– Health is hugely important if you like being on the planet. I’ve been an exercise junky all of my life and, at 67, I think it is paying off nicely for me.
– Of course, nothing is for sure and I could drop tomorrow. But for today, I’m deeply pleased at how I’m weathering the aging process.
– You are what you do. You are what you think. it does’t get much simpler than that.

Identical twins in Finland who shared the same sports and other physical activities as youngsters but different exercise habits as adults soon developed quite different bodies and brains, according to a fascinating new study that highlights the extent to which exercise shapes our health, even in people who have identical genes and nurturing.
Determining the precise, long-term effects of exercise is surprisingly difficult. Most large-scale exercise studies rely on questionnaires or interviews and medical records to establish the role of exercise. But these epidemiological studies, while important and persuasive, cannot prove that exercise causes health changes, only that people who exercise tend to be healthier than those who do not.
To prove that exercise directly causes a change in people’s bodies, scientists must mount randomized controlled trials, during which one group of people works out while a control group does not. But these experiments are complicated and costly and, even in the best circumstances, cannot control for volunteers’ genetics and backgrounds.
And genetics and upbringing matter when it comes to exercise. Genes affect our innate endurance capacity, how well we respond to different types of exercise, and whether we enjoy working out at all. Childhood environment also influences all of this, muddying the results of even well-conducted exercise experiments.
All of this makes identical twins so valuable. By definition, these pairs have the same DNA. If they were raised in the same household, they also had similar upbringing. So they can provide a way to study the effects of changes in lifestyle among people with the same genes and pasts.
Some past studies had found that older identical twins whose workout habits had diverged over the years tended to age differently, with greater risks of poor health and early death among the sedentary twin.
But no studies had looked at young twins and the impacts of different exercise routines on their health. So for the new study, which was published this month in Medicine & Science in Sports & Exercise, researchers at the University of Jyvaskyla and other institutions in Finland turned to that country’s extensive FinnTwin16 database, which contained twins’ answers to questionnaires about their health and medical conditions, beginning when the pairs were 16 and repeated every few years afterward.
The researchers were looking for young adult identical twins in their early- to mid-20s whose exercise habits had substantially diverged after they had left their childhood homes. These twins were not easy to find. Most of the pairs had maintained remarkably similar exercise routines, despite living apart.
But eventually the researchers homed in on 10 pairs of male identical twins, one of whom regularly exercised, while the other did not, usually because of work or family pressures, the researchers determined.
The dissimilarities in their exercise routines had mostly begun within the past three years, according to their questionnaires.
The scientists invited these twins into the lab and measured each young man’s endurance capacity, body composition and insulin sensitivity, to determine their fitness and metabolic health. The scientists also scanned each twin’s brain.
Then they compared the twins’ results.
It turned out that these genetically identical twins looked surprisingly different beneath the skin and skull. The sedentary twins had lower endurance capacities, higher body fat percentages, and signs of insulin resistance, signaling the onset of metabolic problems. (Interestingly, the twins tended to have very similar diets, whatever their workout routines, so food choices were unlikely to have contributed to health differences.)
The twins’ brains also were unalike. The active twins had significantly more grey matter than the sedentary twins, especially in areas of the brain involved in motor control and coordination.
Presumably, all of these differences in the young men’s bodies and brains had developed during their few, brief years of divergent workouts, underscoring how rapidly and robustly exercising — or not — can affect health, said Dr. Urho Kujala, a professor of sports and exercise medicine at the University of Jyvaskyla who oversaw the study.
Of course, the study was small and not a formal randomized trial, although it involved identical twins.
But Dr. Kujala said he believes that the results strongly imply that the differences in the twin’s exercise habits caused the differences in their bodies.
More subtly, the findings also point out that genetics and environment “do not have to be” destiny when it comes to exercise habits, Dr. Kujala said. For these particular twins, whether their genes and childhoods nudged them toward exercising regularly or slumping on the couch, one of the pair overcame that legacy and did the opposite (for better and worse).
The rest of us can do likewise, Dr. Kujala said. Even if the input from our DNA and upbringing urges us to skip the gym, we can “move more,” he said, and, based on this study, rapidly and substantially improve the condition of our bodies and brains.

– Most excellent article by, arguably, the most sincere and honest president during my lifetime. Too bad that the American electorate did’t think he had the right stuff but then they seem drawn to ‘strong leaders with easy to grasp sound-bite answers’ – much to the detriment of the country and the world.
– Bravo, Jimmy Carter!

Women and girls have been discriminated against for too long in a twisted interpretation of the word of God.
I HAVE been a practising Christian all my life and a deacon and Bible teacher for many years. My faith is a source of strength and comfort to me, as religious beliefs are to hundreds of millions of people around the world. So my decision to sever my ties with the Southern Baptist Convention, after six decades, was painful and difficult. It was, however, an unavoidable decision when the convention’s leaders, quoting a few carefully selected Bible verses and claiming that Eve was created second to Adam and was responsible for original sin, ordained that women must be “subservient” to their husbands and prohibited from serving as deacons, pastors or chaplains in the military service.
This view that women are somehow inferior to men is not restricted to one religion or belief. Women are prevented from playing a full and equal role in many faiths. Nor, tragically, does its influence stop at the walls of the church, mosque, synagogue or temple. This discrimination, unjustifiably attributed to a Higher Authority, has provided a reason or excuse for the deprivation of women’s equal rights across the world for centuries.
At its most repugnant, the belief that women must be subjugated to the wishes of men excuses slavery, violence, forced prostitution, genital mutilation and national laws that omit rape as a crime. But it also costs many millions of girls and women control over their own bodies and lives, and continues to deny them fair access to education, health, employment and influence within their own communities.
The impact of these religious beliefs touches every aspect of our lives. They help explain why in many countries boys are educated before girls; why girls are told when and whom they must marry; and why many face enormous and unacceptable risks in pregnancy and childbirth because their basic health needs are not met.
In some Islamic nations, women are restricted in their movements, punished for permitting the exposure of an arm or ankle, deprived of education, prohibited from driving a car or competing with men for a job. If a woman is raped, she is often most severely punished as the guilty party in the crime.
The same discriminatory thinking lies behind the continuing gender gap in pay and why there are still so few women in office in the West. The root of this prejudice lies deep in our histories, but its impact is felt every day. It is not women and girls alone who suffer. It damages all of us. The evidence shows that investing in women and girls delivers major benefits for society. An educated woman has healthier children. She is more likely to send them to school. She earns more and invests what she earns in her family.
It is simply self-defeating for any community to discriminate against half its population. We need to challenge these self-serving and outdated attitudes and practices – as we are seeing in Iran where women are at the forefront of the battle for democracy and freedom.
I understand, however, why many political leaders can be reluctant about stepping into this minefield. Religion, and tradition, are powerful and sensitive areas to challenge. But my fellow Elders and I, who come from many faiths and backgrounds, no longer need to worry about winning votes or avoiding controversy – and we are deeply committed to challenging injustice wherever we see it.
The Elders are an independent group of eminent global leaders, brought together by former South African president Nelson Mandela, who offer their influence and experience to support peace building, help address major causes of human suffering and promote the shared interests of humanity. We have decided to draw particular attention to the responsibility of religious and traditional leaders in ensuring equality and human rights and have recently published a statement that declares: “The justification of discrimination against women and girls on grounds of religion or tradition, as if it were prescribed by a Higher Authority, is unacceptable.”
We are calling on all leaders to challenge and change the harmful teachings and practices, no matter how ingrained, which justify discrimination against women. We ask, in particular, that leaders of all religions have the courage to acknowledge and emphasise the positive messages of dignity and equality that all the world’s major faiths share.
The carefully selected verses found in the Holy Scriptures to justify the superiority of men owe more to time and place – and the determination of male leaders to hold onto their influence – than eternal truths. Similar biblical excerpts could be found to support the approval of slavery and the timid acquiescence to oppressive rulers.
I am also familiar with vivid descriptions in the same Scriptures in which women are revered as pre-eminent leaders. During the years of the early Christian church women served as deacons, priests, bishops, apostles, teachers and prophets. It wasn’t until the fourth century that dominant Christian leaders, all men, twisted and distorted Holy Scriptures to perpetuate their ascendant positions within the religious hierarchy.
The truth is that male religious leaders have had – and still have – an option to interpret holy teachings either to exalt or subjugate women. They have, for their own selfish ends, overwhelmingly chosen the latter. Their continuing choice provides the foundation or justification for much of the pervasive persecution and abuse of women throughout the world. This is in clear violation not just of the Universal Declaration of Human Rights but also the teachings of Jesus Christ, the Apostle Paul, Moses and the prophets, Muhammad, and founders of other great religions – all of whom have called for proper and equitable treatment of all the children of God. It is time we had the courage to challenge these views.

– A long time ago in 1968, in coastal Texas, I tried LSD for the first time. I think it was very likely a “Owsley” tab since it came to me through musicians playing up in Houston. I’d never tried anything other than alcohol before that. It was an amazing experience.
– UPDATE: Owsley actually died in 2011. The article quoted here did not mention that so I assumed it was recent news. Regardless, he and his LSD adventures are, I think, highly interesting.
= = = = = = = = = = = = = = = = = = = = = = = = =
Self-taught chemist Owsley “Bear” Stanley, a legend of the 1960s psychedelic underground who produced the LSD that fueled Ken Kesey’s “acid tests” and the Grateful Dead’s acid rock, died March 13 after a car accident in Queensland, Australia, where he had lived since the 1980s. He was 76.
Mr. Stanley, the grandson of a Kentucky governor, grew up in the Washington area before he found his calling in Berkeley,Calif., as an early patron of the Dead and one of the first people to produce mass quantities of acid.
“I just wanted to know the dose and purity of what I took into my own body,” he told Rolling Stone magazine in 2007. “Almost before I realized what was happening, the whole affair had gotten completely out of hand. I was riding a magic stallion. A Pegasus. I was not responsible for his wings, but they did carry me to all kinds of places.”
Working at first from a makeshift bathroom laboratory in Berkeley, Mr. Stanley produced at least 1 million doses of LSD between 1965 and 1967.
A stubborn, fast-talking perfectionist, he discarded any batch suspected of impurities and soon gained a reputation for producing reliably pure and powerful LSD. His customers were rock stars, Haight-Ashbury hippies and an ever-widening circle of people who wanted to be part of the hallucinogenic era. It made him a fortune.

Two new studies further support the theory that our political decision making could have a neurological basis
It is still considered highly uncool to ascribe a person’s political beliefs, even in part, to that person’s biology: hormones, physiological responses, even brain structures and genes. And no wonder: Doing so raises all kinds of thorny, non-PC issues involving free will, determinism, toleration, and much else.
There’s just one problem: Published scientific research keeps going there, with ever increasing audacity (not to mention growing stacks of data).
The past two weeks have seen not one but two studies published in scientific journals on the biological underpinnings of political ideology. And these studies go straight at the role of genes and the brain in shaping our views, and even our votes.
First, in the American Journal of Political Science, a team of researchers including Peter Hatemi of Penn State University and Rose McDermott of Brown University studied the relationship between our deep-seated tendencies to experience fear—tendencies that vary from person to person, partly for reasons that seem rooted in our genes—and our political beliefs. What they found is that people who have more fearful disposition also tend to be more politically conservative, and less tolerant of immigrants and people of races different from their own. As McDermott carefully emphasizes, that does not mean that every conservative has a high fear disposition. “It’s not that conservative people are more fearful, it’s that fearful people are more conservative,” as she puts it.
I interviewed the paper’s lead author, Peter Hatemi, about his research for my 2012 book The Republican Brain. Hatemi is both a political scientist and also a microbiologist, and as he stressed to me, “nothing is all genes, or all environment.” These forces combine to make us who we are, in incredibly intricate ways.
And if Hatemi’s and McDermott’s research blows your mind, get this: Darren Schreiber, a political neuroscientist at the University of Exeter in the United Kingdom, first performed brain scans on 82 people participating in a risky gambling task, one in which holding out for more money increases your possible rewards, but also your possible losses. Later, cross-referencing the findings with the participants’ publicly available political party registration information, Schreiber noticed something astonishing: Republicans, when they took the same gambling risk, were activating a different part of the brain than Democrats.
Republicans were using the right amygdala, the center of the brain’s threat response system. Democrats, in contrast, were using the insula, involved in internal monitoring of one’s feelings. Amazingly, Schreiber and his colleagues write that this test predicted 82.9 percent of the study subjects’ political party choices—considerably better, they note, than a simple model that predicts your political party affiliation based on the affiliation of your parents.
I also interviewed Schreiber for The Republican Brain. He’s a scientist who was once quite cautious about the relevance of brain studies to people’s politics. As he put it to me: “If you had called me four years ago and said, ‘What is your view on whether Republicans and Democrats have different brains?’ I would have said no.” Now, his own published research suggests otherwise.
One again, though, there’s a critical nuance here. Schreiber thinks the current research suggests not only that having a particular brain influences your political views, but also that having a particular political view influences and changes your brain. The causal arrow seems likely to run in both directions—which would make sense in light of what we know about the plasticity of the brain. Simply by living our lives, we change our brains. Our political affiliations, and the lifestyles that go along with them, probably condition many such changes.
The two new studies described here are likely connected: It is hard not to infer that fear of outsiders or those different from you—along with greater fear dispositions in general—may be related to the role of amygdala, a brain structure that has been dubbed the “heart and soul of the fear system.” The amygdala has been repeatedly implicated in politics. Indeed, Schreiber’s research builds on prior brain studies: In a group of University College of London students, for instance, conservatives showed more gray matter in the right amygdala.
So what’s the upshot? How about this: We need a much broader and more thoughtful discussion about what it means if political ideology turns out to be nothing like what we actually thought it was. Scientists working in this new field tend towards the conclusion that the new research should make us more tolerant, not less, of political difference—not to mention a whole lot more humble about our own deeply held beliefs.
– In 1999, Motorola, at my request, sent me to Silicon Valley for a week-long course in advanced Windows Win32 programming.
– During this course, I remember talking with another participant; a young computer whiz who was from the NSA.
– He talked about how they (the NSA computer guys) conducted red-team green-team battles to see who could infiltrate the other’s team’s computer systems.
– But the thing he talked about, that caught my interest the most, was when he said the hot new frontier was getting into firmware as a way of exerting control over computers remotely. It was a new idea that immediately fascinated me but once he saw my interest, I think he realized that he might be talking too much and clammed up. He avoided me for the rest of the week.
– The story, below, says that the technique of firmware infiltration may have been around since 2001. I’m sure I heard the sound of the other shoe dropping when I read that.
– The article says:
It is not clear how the NSA may have obtained the hard drives’ source code. Western Digital spokesman Steve Shattuck said the company “has not provided its source code to government agencies.” The other hard drive makers would not say if they had shared their source code with the NSA.
– I don’t find it all that mysterous. How hard would it be for the NSA to field computer-savvy agents directed to seek employment in these companies? Or, as the article says, to require the companies to provide their source code to the NSA for security reviews before the U.S. Government will allow it to be used in U.S. facilities?
– Once the NSA has the firmware’s source code, they can modify it and then intercept the firm’s drives in shipment and refresh the firmware on the intercepted drives with the NSA’s new stuff … that does everything the old firmware does … and a bit more.
– The interception-during-shipment technique was outed over a year ago as being one of their favorite techniques though in that case it had to do with routers.

The US National Security Agency has figured out how to hide spying software deep within hard drives made by Western Digital, Seagate, Toshiba and other top manufacturers, giving the agency the means to eavesdrop on the majority of the world’s computers, according to cyber researchers and former operatives.
That long-sought and closely guarded ability was part of a cluster of spying programs discovered by Kaspersky Lab, the Moscow-based security software maker that has exposed a series of Western cyberespionage operations.
Kaspersky said it found personal computers in 30 countries infected with one or more of the spying programs, with the most infections seen in Iran, followed by Russia, Pakistan, Afghanistan, China, Mali, Syria, Yemen and Algeria. The targets included government and military institutions, telecommunication companies, banks, energy companies, nuclear researchers, media, and Islamic activists, Kaspersky said.
The firm declined to publicly name the country behind the spying campaign, but said it was closely linked to Stuxnet, the NSA-led cyberweapon that was used to attack Iran’s uranium enrichment facility. The NSA is the agency responsible for gathering electronic intelligence on behalf of the United States.
A former NSA employee told Reuters that Kaspersky’s analysis was correct, and that people still in the intelligence agency valued these spying programs as highly as Stuxnet. Another former intelligence operative confirmed that the NSA had developed the prized technique of concealing spyware in hard drives, but said he did not know which spy efforts relied on it.
NSA spokeswoman Vanee Vines declined to comment.
Kaspersky published the technical details of its research on Monday, which should help infected institutions detect the spying programs, some of which trace back as far as 2001.
The disclosure could further hurt the NSA’s surveillance abilities, already damaged by massive leaks by former contractor Edward Snowden. Snowden’s revelations have hurt the United States’ relations with some allies and slowed the sales of US technology products abroad.
The exposure of these new spying tools could lead to greater backlash against Western technology, particularly in countries such as China, which is already drafting regulations that would require most bank technology suppliers to proffer copies of their software code for inspection.
According to Kaspersky, the spies made a technological breakthrough by figuring out how to lodge malicious software in the obscure code called firmware that launches every time a computer is turned on.
Disk drive firmware is viewed by spies and cybersecurity experts as the second-most valuable real estate on a PC for a hacker, second only to the BIOS code invoked automatically as a computer boots up.
“The hardware will be able to infect the computer over and over,” lead Kaspersky researcher Costin Raiu said in an interview.
Though the leaders of the still-active espionage campaign could have taken control of thousands of PCs, giving them the ability to steal files or eavesdrop on anything they wanted, the spies were selective and only established full remote control over machines belonging to the most desirable foreign targets, according to Raiu. He said Kaspersky found only a few especially high-value computers with the hard-drive infections.
Kaspersky’s reconstructions of the spying programs show that they could work in disk drives sold by more than a dozen companies, comprising essentially the entire market. They include Western Digital, Seagate, Toshiba, IBM, Micron Technology and Samsung.
Western Digital, Seagate and Micron said they had no knowledge of these spying programs. Toshiba and Samsung declined to comment. IBM did not respond to requests for comment.
GETTING THE SOURCE CODE
Raiu said the authors of the spying programs must have had access to the proprietary source code that directs the actions of the hard drives. That code can serve as a roadmap to vulnerabilities, allowing those who study it to launch attacks much more easily.
“There is zero chance that someone could rewrite the [hard drive] operating system using public information,” Raiu said.
Concerns about access to source code flared after a series of high-profile cyberattacks on Google Inc and other US companies in 2009 that were blamed on China. Investigators have said they found evidence that the hackers gained access to source code from several big US tech and defense companies.
It is not clear how the NSA may have obtained the hard drives’ source code. Western Digital spokesman Steve Shattuck said the company “has not provided its source code to government agencies.” The other hard drive makers would not say if they had shared their source code with the NSA.
Seagate spokesman Clive Over said it has “secure measures to prevent tampering or reverse engineering of its firmware and other technologies.” Micron spokesman Daniel Francisco said the company took the security of its products seriously and “we are not aware of any instances of foreign code.”
According to former intelligence operatives, the NSA has multiple ways of obtaining source code from tech companies, including asking directly and posing as a software developer. If a company wants to sell products to the Pentagon or another sensitive US agency, the government can request a security audit to make sure the source code is safe.
“They don’t admit it, but they do say, ‘We’re going to do an evaluation, we need the source code,'” said Vincent Liu, a partner at security consulting firm Bishop Fox and former NSA analyst. “It’s usually the NSA doing the evaluation, and it’s a pretty small leap to say they’re going to keep that source code.”
Kaspersky called the authors of the spying program “the Equation group,” named after their embrace of complex encryption formulas.
The group used a variety of means to spread other spying programs, such as by compromising jihadist websites, infecting USB sticks and CDs, and developing a self-spreading computer worm called Fanny, Kasperky said.
Fanny was like Stuxnet in that it exploited two of the same undisclosed software flaws, known as “zero days,” which strongly suggested collaboration by the authors, Raiu said. He added that it was “quite possible” that the Equation group used Fanny to scout out targets for Stuxnet in Iran and spread the virus.

Research into psychedelics, shut down for decades, is now yielding exciting results.
On an April Monday in 2010, Patrick Mettes, a fifty-four-year-old television news director being treated for a cancer of the bile ducts, read an article on the front page of the Times that would change his death. His diagnosis had come three years earlier, shortly after his wife, Lisa, noticed that the whites of his eyes had turned yellow. By 2010, the cancer had spread to Patrick’s lungs and he was buckling under the weight of a debilitating chemotherapy regimen and the growing fear that he might not survive. The article, headlined “HALLUCINOGENS HAVE DOCTORS TUNING IN AGAIN,” mentioned clinical trials at several universities, including N.Y.U., in which psilocybin—the active ingredient in so-called magic mushrooms—was being administered to cancer patients in an effort to relieve their anxiety and “existential distress.” One of the researchers was quoted as saying that, under the influence of the hallucinogen, “individuals transcend their primary identification with their bodies and experience ego-free states . . . and return with a new perspective and profound acceptance.” Patrick had never taken a psychedelic drug, but he immediately wanted to volunteer. Lisa was against the idea. “I didn’t want there to be an easy way out,” she recently told me. “I wanted him to fight.”
Patrick made the call anyway and, after filling out some forms and answering a long list of questions, was accepted into the trial. Since hallucinogens can sometimes bring to the surface latent psychological problems, researchers try to weed out volunteers at high risk by asking questions about drug use and whether there is a family history of schizophrenia or bipolar disorder. After the screening, Mettes was assigned to a therapist named Anthony Bossis, a bearded, bearish psychologist in his mid-fifties, with a specialty in palliative care. Bossis is a co-principal investigator for the N.Y.U. trial.
After four meetings with Bossis, Mettes was scheduled for two dosings—one of them an “active” placebo (in this case, a high dose of niacin, which can produce a tingling sensation), and the other a pill containing the psilocybin. Both sessions, Mettes was told, would take place in a room decorated to look more like a living room than like a medical office, with a comfortable couch, landscape paintings on the wall, and, on the shelves, books of art and mythology, along with various aboriginal and spiritual tchotchkes, including a Buddha and a glazed ceramic mushroom. During each session, which would last the better part of a day, Mettes would lie on the couch wearing an eye mask and listening through headphones to a carefully curated playlist—Brian Eno, Philip Glass, Pat Metheny, Ravi Shankar. Bossis and a second therapist would be there throughout, saying little but being available to help should he run into any trouble.
I met Bossis last year in the N.Y.U. treatment room, along with his colleague Stephen Ross, an associate professor of psychiatry at N.Y.U.’s medical school, who directs the ongoing psilocybin trials. Ross, who is in his forties, was dressed in a suit and could pass for a banker. He is also the director of the substance-abuse division at Bellevue, and he told me that he had known little about psychedelics—drugs that produce radical changes in consciousness, including hallucinations—until a colleague happened to mention that, in the nineteen-sixties, LSD had been used successfully to treat alcoholics. Ross did some research and was astounded at what he found.
“I felt a little like an archeologist unearthing a completely buried body of knowledge,” he said. Beginning in the nineteen-fifties, psychedelics had been used to treat a wide variety of conditions, including alcoholism and end-of-life anxiety. The American Psychiatric Association held meetings centered on LSD. “Some of the best minds in psychiatry had seriously studied these compounds in therapeutic models, with government funding,” Ross said.
Between 1953 and 1973, the federal government spent four million dollars to fund a hundred and sixteen studies of LSD, involving more than seventeen hundred subjects. (These figures don’t include classified research.) Through the mid-nineteen-sixties, psilocybin and LSD were legal and remarkably easy to obtain. Sandoz, the Swiss chemical company where, in 1938, Albert Hofmann first synthesized LSD, gave away large quantities of Delysid—LSD—to any researcher who requested it, in the hope that someone would discover a marketable application. Psychedelics were tested on alcoholics, people struggling with obsessive-compulsive disorder, depressives, autistic children, schizophrenics, terminal cancer patients, and convicts, as well as on perfectly healthy artists and scientists (to study creativity) and divinity students (to study spirituality). The results reported were frequently positive. But many of the studies were, by modern standards, poorly designed and seldom well controlled, if at all. When there were controls, it was difficult to blind the researchers—that is, hide from them which volunteers had taken the actual drug. (This remains a problem.)
By the mid-nineteen-sixties, LSD had escaped from the laboratory and swept through the counterculture. In 1970, Richard Nixon signed the Controlled Substances Act and put most psychedelics on Schedule 1, prohibiting their use for any purpose. Research soon came to a halt, and what had been learned was all but erased from the field of psychiatry. “By the time I got to medical school, no one even talked about it,” Ross said.
The clinical trials at N.Y.U.—a second one, using psilocybin to treat alcohol addiction, is now getting under way—are part of a renaissance of psychedelic research taking place at several universities in the United States, including Johns Hopkins, the Harbor-U.C.L.A. Medical Center, and the University of New Mexico, as well as at Imperial College, in London, and the University of Zurich. As the drug war subsides, scientists are eager to reconsider the therapeutic potential of these drugs, beginning with psilocybin. (Last month The Lancet, the United Kingdom’s most prominent medical journal, published a guest editorial in support of such research.) The effects of psilocybin resemble those of LSD, but, as one researcher explained, “it carries none of the political and cultural baggage of those three letters.” LSD is also stronger and longer-lasting in its effects, and is considered more likely to produce adverse reactions. Researchers are using or planning to use psilocybin not only to treat anxiety, addiction (to smoking and alcohol), and depression but also to study the neurobiology of mystical experience, which the drug, at high doses, can reliably occasion. Forty years after the Nixon Administration effectively shut down most psychedelic research, the government is gingerly allowing a small number of scientists to resume working with these powerful and still somewhat mysterious molecules.
As I chatted with Tony Bossis and Stephen Ross in the treatment room at N.Y.U., their excitement about the results was evident. According to Ross, cancer patients receiving just a single dose of psilocybin experienced immediate and dramatic reductions in anxiety and depression, improvements that were sustained for at least six months. The data are still being analyzed and have not yet been submitted to a journal for peer review, but the researchers expect to publish later this year.
“I thought the first ten or twenty people were plants—that they must be faking it,” Ross told me. “They were saying things like ‘I understand love is the most powerful force on the planet,’ or ‘I had an encounter with my cancer, this black cloud of smoke.’ People who had been palpably scared of death—they lost their fear. The fact that a drug given once can have such an effect for so long is an unprecedented finding. We have never had anything like it in the psychiatric field.”
I was surprised to hear such unguarded enthusiasm from a scientist, and a substance-abuse specialist, about a street drug that, since 1970, has been classified by the government as having no accepted medical use and a high potential for abuse. But the support for renewed research on psychedelics is widespread among medical experts. “I’m personally biased in favor of these type of studies,” Thomas R. Insel, the director of the National Institute of Mental Health (N.I.M.H.) and a neuroscientist, told me. “If it proves useful to people who are really suffering, we should look at it. Just because it is a psychedelic doesn’t disqualify it in our eyes.” Nora Volkow, the director of the National Institute on Drug Abuse (NIDA), emphasized that “it is important to remind people that experimenting with drugs of abuse outside a research setting can produce serious harms.”
Many researchers I spoke with described their findings with excitement, some using words like “mind-blowing.” Bossis said, “People don’t realize how few tools we have in psychiatry to address existential distress. Xanax isn’t the answer. So how can we not explore this, if it can recalibrate how we die?”
Herbert D. Kleber, a psychiatrist and the director of the substance-abuse division at the Columbia University–N.Y. State Psychiatric Institute, who is one of the nation’s leading experts on drug abuse, struck a cautionary note. “The whole area of research is fascinating,” he said. “But it’s important to remember that the sample sizes are small.” He also stressed the risk of adverse effects and the importance of “having guides in the room, since you can have a good experience or a frightful one.” But he added, referring to the N.Y.U. and Johns Hopkins research, “These studies are being carried out by very well trained and dedicated therapists who know what they’re doing. The question is, is it ready for prime time?”
The idea of giving a psychedelic drug to the dying was conceived by a novelist: Aldous Huxley. In 1953, Humphry Osmond, an English psychiatrist, introduced Huxley to mescaline, an experience he chronicled in “The Doors of Perception,” in 1954. (Osmond coined the word “psychedelic,” which means “mind-manifesting,” in a 1957 letter to Huxley.) Huxley proposed a research project involving the “administration of LSD to terminal cancer cases, in the hope that it would make dying a more spiritual, less strictly physiological process.” Huxley had his wife inject him with the drug on his deathbed; he died at sixty-nine, of laryngeal cancer, on November 22, 1963.
Psilocybin mushrooms first came to the attention of Western medicine (and popular culture) in a fifteen-page 1957 Life article by an amateur mycologist—and a vice-president of J. P. Morgan in New York—named R. Gordon Wasson. In 1955, after years spent chasing down reports of the clandestine use of magic mushrooms among indigenous Mexicans, Wasson was introduced to them by María Sabina, a curandera—a healer, or shaman—in southern Mexico. Wasson’s awed first-person account of his psychedelic journey during a nocturnal mushroom ceremony inspired several scientists, including Timothy Leary, a well-regarded psychologist doing personality research at Harvard, to take up the study of psilocybin. After trying magic mushrooms in Cuernavaca, in 1960, Leary conceived the Harvard Psilocybin Project, to study the therapeutic potential of hallucinogens. His involvement with LSD came a few years later.
In the wake of Wasson’s research, Albert Hofmann experimented with magic mushrooms in 1957. “Thirty minutes after my taking the mushrooms, the exterior world began to undergo a strange transformation,” he wrote. “Everything assumed a Mexican character.” Hofmann proceeded to identify, isolate, and then synthesize the active ingredient, psilocybin, the compound being used in the current research.
Perhaps the most influential and rigorous of these early studies was the Good Friday experiment, conducted in 1962 by Walter Pahnke, a psychiatrist and minister working on a Ph.D. dissertation under Leary at Harvard. In a double-blind experiment, twenty divinity students received a capsule of white powder right before a Good Friday service at Marsh Chapel, on the Boston University campus; ten contained psilocybin, ten an active placebo (nicotinic acid). Eight of the ten students receiving psilocybin reported a mystical experience, while only one in the control group experienced a feeling of “sacredness” and a “sense of peace.” (Telling the subjects apart was not difficult, rendering the double-blind a somewhat hollow conceit: those on the placebo sat sedately in their pews while the others lay down or wandered around the chapel, muttering things like “God is everywhere” and “Oh, the glory!”) Pahnke concluded that the experiences of eight who received the psilocybin were “indistinguishable from, if not identical with,” the classic mystical experiences reported in the literature by William James, Walter Stace, and others.
In 1991, Rick Doblin, the director of the Multidisciplinary Association for Psychedelic Studies (MAPS), published a follow-up study, in which he tracked down all but one of the divinity students who received psilocybin at Marsh Chapel and interviewed seven of them. They all reported that the experience had shaped their lives and work in profound and enduring ways. But Doblin found flaws in Pahnke’s published account: he had failed to mention that several subjects struggled with acute anxiety during their experience. One had to be restrained and given Thorazine, a powerful antipsychotic, after he ran from the chapel and headed down Commonwealth Avenue, convinced that he had been chosen to announce that the Messiah had arrived.
The first wave of research into psychedelics was doomed by an excessive exuberance about their potential. For people working with these remarkable molecules, it was difficult not to conclude that they were suddenly in possession of news with the power to change the world—a psychedelic gospel. They found it hard to justify confining these drugs to the laboratory or using them only for the benefit of the sick. It didn’t take long for once respectable scientists such as Leary to grow impatient with the rigmarole of objective science. He came to see science as just another societal “game,” a conventional box it was time to blow up—along with all the others.
Was the suppression of psychedelic research inevitable? Stanislav Grof, a Czech-born psychiatrist who used LSD extensively in his practice in the nineteen-sixties, believes that psychedelics “loosed the Dionysian element” on America, posing a threat to the country’s Puritan values that was bound to be repulsed. (He thinks the same thing could happen again.) Roland Griffiths, a psychopharmacologist at Johns Hopkins University School of Medicine, points out that ours is not the first culture to feel threatened by psychedelics: the reason Gordon Wasson had to rediscover magic mushrooms in Mexico was that the Spanish had suppressed them so thoroughly, deeming them dangerous instruments of paganism.
“There is such a sense of authority that comes out of the primary mystical experience that it can be threatening to existing hierarchical structures,” Griffiths told me when we met in his office last spring. “We ended up demonizing these compounds. Can you think of another area of science regarded as so dangerous and taboo that all research gets shut down for decades? It’s unprecedented in modern science.”
Early in 2006, Tony Bossis, Stephen Ross, and Jeffrey Guss, a psychiatrist and N.Y.U. colleague, began meeting after work on Friday afternoons to read up on and discuss the scientific literature on psychedelics. They called themselves the P.R.G., or Psychedelic Reading Group, but within a few months the “R” in P.R.G. had come to stand for “Research.” They had decided to try to start an experimental trial at N.Y.U., using psilocybin alongside therapy to treat anxiety in cancer patients. The obstacles to such a trial were formidable: Would the F.D.A. and the D.E.A. grant permission to use the drug? Would N.Y.U.’s Institutional Review Board, charged with protecting experimental subjects, allow them to administer a psychedelic to cancer patients? Then, in July of 2006, the journal Psychopharmacology published a landmark article by Roland Griffiths, et al., titled “Psilocybin Can Occasion Mystical-Type Experiences Having Substantial and Sustained Personal Meaning and Spiritual Significance.”
“We all rushed in with Roland’s article,” Bossis recalls. “It solidified our confidence that we could do this work. Johns Hopkins had shown it could be done safely.” The article also gave Ross the ammunition he needed to persuade a skeptical I.R.B. “The fact that psychedelic research was being done at Hopkins—considered the premier medical center in the country—made it easier to get it approved here. It was an amazing study, with such an elegant design. And it opened up the field.” (Even so, psychedelic research remains tightly regulated and closely scrutinized. The N.Y.U. trial could not begin until Ross obtained approvals first from the F.D.A., then from N.Y.U.’s Oncology Review Board, and then from the I.R.B., the Bellevue Research Review Committee, the Bluestone Center for Clinical Research, the Clinical and Translational Science Institute, and, finally, the Drug Enforcement Administration, which must grant the license to use a Schedule 1 substance.)
Griffiths’s double-blind study reprised the work done by Pahnke in the nineteen-sixties, but with considerably more scientific rigor. Thirty-six volunteers, none of whom had ever taken a hallucinogen, received a pill containing either psilocybin or an active placebo (methylphenidate, or Ritalin); in a subsequent session the pills were reversed. “When administered under supportive conditions,” the paper concluded, “psilocybin occasioned experiences similar to spontaneously occurring mystical experiences.” Participants ranked these experiences as among the most meaningful in their lives, comparable to the birth of a child or the death of a parent. Two-thirds of the participants rated the psilocybin session among the top five most spiritually significant experiences of their lives; a third ranked it at the top. Fourteen months later, these ratings had slipped only slightly.
Furthermore, the “completeness” of the mystical experience closely tracked the improvements reported in personal well-being, life satisfaction, and “positive behavior change” measured two months and then fourteen months after the session. (The researchers relied on both self-assessments and the assessments of co-workers, friends, and family.) The authors determined the completeness of a mystical experience using two questionnaires, including the Pahnke-Richards Mystical Experience Questionnaire, which is based in part on William James’s writing in “The Varieties of Religious Experience.” The questionnaire measures feelings of unity, sacredness, ineffability, peace and joy, as well as the impression of having transcended space and time and the “noetic sense” that the experience has disclosed some objective truth about reality. A “complete” mystical experience is one that exhibits all six characteristics. Griffiths believes that the long-term effectiveness of the drug is due to its ability to occasion such a transformative experience, but not by changing the brain’s long-term chemistry, as a conventional psychiatric drug like Prozac does.
A follow-up study by Katherine MacLean, a psychologist in Griffiths’s lab, found that the psilocybin experience also had a positive and lasting effect on the personality of most participants. This is a striking result, since the conventional wisdom in psychology holds that personality is usually fixed by age thirty and thereafter is unlikely to substantially change. But more than a year after their psilocybin sessions volunteers who had had the most complete mystical experiences showed significant increases in their “openness,” one of the five domains that psychologists look at in assessing personality traits. (The others are conscientiousness, extroversion, agreeableness, and neuroticism.) Openness, which encompasses aesthetic appreciation, imagination, and tolerance of others’ viewpoints, is a good predictor of creativity.
“I don’t want to use the word ‘mind-blowing,’ ” Griffiths told me, “but, as a scientific phenomenon, if you can create conditions in which seventy per cent of people will say they have had one of the five most meaningful experiences of their lives? To a scientist, that’s just incredible.”
The revival of psychedelic research today owes much to the respectability of its new advocates. At sixty-eight, Roland Griffiths, who was trained as a behaviorist and holds senior appointments in psychiatry and neuroscience at Hopkins, is one of the nation’s leading drug-addiction researchers. More than six feet tall, he is rail-thin and stands bolt upright; the only undisciplined thing about him is a thatch of white hair so dense that it appears to have held his comb to a draw. His long, productive relationship with NIDA has resulted in some three hundred and fifty papers, with titles such as “Reduction of Heroin Self-Administration in Baboons by Manipulation of Behavioral and Pharmacological Conditions.” Tom Insel, the director of the N.I.M.H., described Griffiths as “a very careful, thoughtful scientist” with “a reputation for meticulous data analysis. So it’s fascinating that he’s now involved in an area that other people might view as pushing the edge.”
Griffiths’s career took an unexpected turn in the nineteen-nineties after two serendipitous introductions. The first came when a friend introduced him to Siddha Yoga, in 1994. He told me that meditation acquainted him with “something way, way beyond a material world view that I can’t really talk to my colleagues about, because it involves metaphors or assumptions that I’m really uncomfortable with as a scientist.” He began entertaining “fanciful thoughts” of quitting science and going to India.
In 1996, an old friend and colleague named Charles R. (Bob) Schuster, recently retired as the head of NIDA, suggested that Griffiths talk to Robert Jesse, a young man he’d recently met at Esalen, the retreat center in Big Sur, California. Jesse was neither a medical professional nor a scientist; he was a computer guy, a vice-president at Oracle, who had made it his mission to revive the science of psychedelics, as a tool not so much of medicine as of spirituality. He had organized a gathering of researchers and religious figures to discuss the spiritual and therapeutic potential of psychedelic drugs and how they might be rehabilitated.
When the history of second-wave psychedelic research is written, Bob Jesse will be remembered as one of two scientific outsiders who worked for years, mostly behind the scenes, to get it off the ground. (The other is Rick Doblin, the founder of MAPS.) While on leave from Oracle, Jesse established a nonprofit called the Council on Spiritual Practices, with the aim of “making direct experience of the sacred more available to more people.” (He prefers the term “entheogen,” or “God-facilitating,” to “psychedelic.”) In 1996, the C.S.P. organized the historic gathering at Esalen. Many of the fifteen in attendance were “psychedelic elders,” researchers such as James Fadiman and Willis Harman, both of whom had done early psychedelic research while at Stanford, and religious figures like Huston Smith, the scholar of comparative religion. But Jesse wisely decided to invite an outsider as well: Bob Schuster, a drug-abuse expert who had served in two Republican Administrations. By the end of the meeting, the Esalen group had decided on a plan: “to get aboveboard, unassailable research done, at an institution with investigators beyond reproach,” and, ideally, “do this without any promise of clinical treatment.” Jesse was ultimately less interested in people’s mental disorders than in their spiritual well-being—in using entheogens for what he calls “the betterment of well people.”
Shortly after the Esalen meeting, Bob Schuster (who died in 2011) phoned Jesse to tell him about his old friend Roland Griffiths, whom he described as “the investigator beyond reproach” Jesse was looking for. Jesse flew to Baltimore to meet Griffiths, inaugurating a series of conversations and meetings about meditation and spirituality that eventually drew Griffiths into psychedelic research and would culminate, a few years later, in the 2006 paper in Psychopharmacology.
The significance of the 2006 paper went far beyond its findings. The journal invited several prominent drug researchers and neuroscientists to comment on the study, and all of them treated it as a convincing case for further research. Herbert Kleber, of Columbia, applauded the paper and acknowledged that “major therapeutic possibilities” could result from further psychedelic research studies, some of which “merit N.I.H. support.” Solomon Snyder, the Hopkins neuroscientist who, in the nineteen-seventies, discovered the brain’s opioid receptors, summarized what Griffiths had achieved for the field: “The ability of these researchers to conduct a double-blind, well-controlled study tells us that clinical research with psychedelic drugs need not be so risky as to be off-limits to most investigators.”
Roland Griffiths and Bob Jesse had opened a door that had been tightly shut for more than three decades. Charles Grob, at U.C.L.A., was the first to step through it, winning F.D.A. approval for a Phase I pilot study to assess the safety, dosing, and efficacy of psilocybin in the treatment of anxiety in cancer patients. Next came the Phase II trials, just concluded at both Hopkins and N.Y.U., involving higher doses and larger groups (twenty-nine at N.Y.U.; fifty-six at Hopkins)—including Patrick Mettes and about a dozen other cancer patients in New York and Baltimore whom I recently interviewed.
Since 2006, Griffiths’s lab has conducted a pilot study on the potential of psilocybin to treat smoking addiction, the results of which were published last November in the Journal of Psychopharmacology. The sample is tiny—fifteen smokers—but the success rate is striking. Twelve subjects, all of whom had tried to quit multiple times, using various methods, were verified as abstinent six months after treatment, a success rate of eighty per cent. (Currently, the leading cessation treatment is nicotine-replacement therapy; a recent review article in the BMJ—formerly the British Medical Journal—reported that the treatment helped smokers remain abstinent for six months in less than seven per cent of cases.) In the Hopkins study, subjects underwent two or three psilocybin sessions and a course of cognitive-behavioral therapy to help them deal with cravings. The psychedelic experience seems to allow many subjects to reframe, and then break, a lifelong habit. “Smoking seemed irrelevant, so I stopped,” one subject told me. The volunteers who reported a more complete mystical experience had greater success in breaking the habit. A larger, Phase II trial comparing psilocybin to nicotine replacement (both in conjunction with cognitive behavioral therapy) is getting under way at Hopkins.
“We desperately need a new treatment approach for addiction,” Herbert Kleber told me. “Done in the right hands—and I stress that, because the whole psychedelic area attracts people who often think that they know the truth before doing the science—this could be a very useful one.”
Thus far, criticism of psychedelic research has been limited. Last summer, Florian Holsboer, the director of the Max Planck Institute of Psychiatry, in Munich, told Science, “You can’t give patients some substance just because it has an antidepressant effect on top of many other effects. That’s too dangerous.” Nora Volkow, of NIDA, wrote me in an e-mail that “the main concern we have at NIDA in relation to this work is that the public will walk away with the message that psilocybin is a safe drug to use. In fact, its adverse effects are well known, although not completely predictable.” She added, “Progress has been made in decreasing use of hallucinogens, particularly in young people. We would not want to see that trend altered.”
The recreational use of psychedelics is famously associated with instances of psychosis, flashback, and suicide. But these adverse effects have not surfaced in the trials of drugs at N.Y.U. and Johns Hopkins. After nearly five hundred administrations of psilocybin, the researchers have reported no serious negative effects. This is perhaps less surprising than it sounds, since volunteers are self-selected, carefully screened and prepared for the experience, and are then guided through it by therapists well trained to manage the episodes of fear and anxiety that many volunteers do report. Apart from the molecules involved, a psychedelic therapy session and a recreational psychedelic experience have very little in common.
The lab at Hopkins is currently conducting a study of particular interest to Griffiths: examining the effect of psilocybin on long-term meditators. The study plans to use fMRI—functional magnetic-resonance imaging—to study the brains of forty meditators before, during, and after they have taken psilocybin, to measure changes in brain activity and connectivity and to see what these “trained contemplatives can tell us about the experience.” Griffiths’s lab is also launching a study in collaboration with N.Y.U. that will give the drug to religious professionals in a number of faiths to see how the experience might contribute to their work. “I feel like a kid in a candy shop,” Griffiths told me. “There are so many directions to take this research. It’s a Rip Van Winkle effect—after three decades of no research, we’re rubbing the sleep from our eyes.”
“Ineffability” is a hallmark of the mystical experience. Many struggle to describe the bizarre events going on in their minds during a guided psychedelic journey without sounding like either a New Age guru or a lunatic. The available vocabulary isn’t always up to the task of recounting an experience that seemingly can take someone out of body, across vast stretches of time and space, and include face-to-face encounters with divinities and demons and previews of their own death.
Volunteers in the N.Y.U. psilocybin trial were required to write a narrative of their experience soon after the treatment, and Patrick Mettes, having worked in journalism, took the assignment seriously. His wife, Lisa, said that, after his Friday session, he worked all weekend to make sense of the experience and write it down.
When Mettes arrived at the treatment room, at First Avenue and Twenty-fifth Street, Tony Bossis and Krystallia Kalliontzi, his guides, greeted him, reviewed the day’s plan, and, at 9 A.M., presented him with a small chalice containing the pill. None of them knew whether it contained psilocybin or the placebo. Asked to state his intention, Mettes said that he wanted to learn to cope better with the anxiety and the fear that he felt about his cancer. As the researchers had suggested, he’d brought a few photographs along—of Lisa and him on their wedding day, and of their dog, Arlo—and placed them around the room.
At nine-thirty, Mettes lay down on the couch, put on the headphones and eye mask, and fell silent. In his account, he likened the start of the journey to the launch of a space shuttle, “a physically violent and rather clunky liftoff which eventually gave way to the blissful serenity of weightlessness.”
Several of the volunteers I interviewed reported feeling intense fear and anxiety before giving themselves up to the experience, as the guides encourage them to do. The guides work from a set of “flight instructions” prepared by Bill Richards, a Baltimore psychologist who worked with Stanislav Grof during the nineteen-seventies and now trains a new generation of psychedelic therapists. The document is a summary of the experience accumulated from managing thousands of psychedelic sessions—and countless bad trips—during the nineteen-sixties, whether these took place in therapeutic settings or in the bad-trip tent at Woodstock.
The “same force that takes you deep within will, of its own impetus, return you safely to the everyday world,” the manual offers at one point. Guides are instructed to remind subjects that they’ll never be left alone and not to worry about their bodies while journeying, since the guides will keep an eye on them. If you feel like you’re “dying, melting, dissolving, exploding, going crazy etc.—go ahead,” embrace it: “Climb staircases, open doors, explore paths, fly over landscapes.” And if you confront anything frightening, “look the monster in the eye and move towards it. . . . Dig in your heels; ask, ‘What are you doing in my mind?’ Or, ‘What can I learn from you?’ Look for the darkest corner in the basement, and shine your light there.” This training may help explain why the darker experiences that sometimes accompany the recreational use of psychedelics have not surfaced in the N.Y.U. and Hopkins trials.
Early on, Mettes encountered his brother’s wife, Ruth, who died of cancer more than twenty years earlier, at forty-three. Ruth “acted as my tour guide,” he wrote, and “didn’t seem surprised to see me. She ‘wore’ her translucent body so I would know her.” Michelle Obama made an appearance. “The considerable feminine energy all around me made clear the idea that a mother, any mother, regardless of her shortcomings . . . could never NOT love her offspring. This was very powerful. I know I was crying.” He felt as if he were coming out of the womb, “being birthed again.”
Bossis noted that Mettes was crying and breathing heavily. Mettes said, “Birth and death is a lot of work,” and appeared to be convulsing. Then he reached out and clutched Kalliontzi’s hand while pulling his knees up and pushing, as if he were delivering a baby.
“Oh God,” he said, “it all makes sense now, so simple and beautiful.”
Around noon, Mettes asked to take a break. “It was getting too intense,” he wrote. They helped him to the bathroom. “Even the germs were beautiful, as was everything in our world and universe.” Afterward, he was reluctant to “go back in.” He wrote, “The work was considerable but I loved the sense of adventure.” He put on his eye mask and headphones and lay back down.
“From here on, love was the only consideration. It was and is the only purpose. Love seemed to emanate from a single point of light. And it vibrated.” He wrote that “no sensation, no image of beauty, nothing during my time on earth has felt as pure and joyful and glorious as the height of this journey.”
Then, at twelve-ten, he said something that Bossis jotted down: “O.K., we can all punch out now. I get it.”
He went on to take a tour of his lungs, where he “saw two spots.” They were “no big deal.” Mettes recalled, “I was being told (without words) not to worry about the cancer . . . it’s minor in the scheme of things . . . simply an imperfection of your humanity.”
Then he experienced what he called “a brief death.”
“I approached what appeared to be a very sharp, pointed piece of stainless steel. It had a razor blade quality to it. I continued up to the apex of this shiny metal object and as I arrived, I had a choice, to look or not look, over the edge and into the infinite abyss.” He stared into “the vastness of the universe,” hesitant but not frightened. “I wanted to go all in but felt that if I did, I would possibly leave my body permanently,” he wrote. But he “knew there was much more for me here.” Telling his guides about his choice, he explained that he was “not ready to jump off and leave Lisa.”
Around 3 P.M., it was over. “The transition from a state where I had no sense of time or space to the relative dullness of now, happened quickly. I had a headache.”
When Lisa arrived to take him home, Patrick “looked like he had run a race,” she recalled. “The color in his face was not good, he looked tired and sweaty, but he was fired up.” He told her he had touched the face of God.
Bossis was deeply moved by the session. “You’re in this room, but you’re in the presence of something large,” he recalled. “It’s humbling to sit there. It’s the most rewarding day of your career.”
Every guided psychedelic journey is different, but a few themes seem to recur. Several of the cancer patients I interviewed at N.Y.U. and Hopkins described an experience of either giving birth or being born. Many also described an encounter with their cancer that had the effect of diminishing its power over them. Dinah Bazer, a shy woman in her sixties who had been given a diagnosis of ovarian cancer in 2010, screamed at the black mass of fear she encountered while peering into her rib cage: “Fuck you, I won’t be eaten alive!” Since her session, she says, she has stopped worrying about a recurrence—one of the objectives of the trial.
Great secrets of the universe often become clear during the journey, such as “We are all one” or “Love is all that matters.” The usual ratio of wonder to banality in the adult mind is overturned, and such ideas acquire the force of revealed truth. The result is a kind of conversion experience, and the researchers believe that this is what is responsible for the therapeutic effect.
Subjects revelled in their sudden ability to travel seemingly at will through space and time, using it to visit Elizabethan England, the banks of the Ganges, or Wordsworthian scenes from their childhood. The impediment of a body is gone, as is one’s identity, yet, paradoxically, a perceiving and recording “I” still exists. Several volunteers used the metaphor of a camera being pulled back on the scene of their lives, to a point where matters that had once seemed daunting now appeared manageable—smoking, cancer, even death. Their accounts are reminiscent of the “overview effect” described by astronauts who have glimpsed the earth from a great distance, an experience that some of them say permanently altered their priorities. Roland Griffiths likens the therapeutic experience of psilocybin to a kind of “inverse P.T.S.D.”—“a discrete event that produces persisting positive changes in attitudes, moods, and behavior, and presumably in the brain.”
Death looms large in the journeys taken by the cancer patients. A woman I’ll call Deborah Ames, a breast-cancer survivor in her sixties (she asked not to be identified), described zipping through space as if in a video game until she arrived at the wall of a crematorium and realized, with a fright, “I’ve died and now I’m going to be cremated. The next thing I know, I’m below the ground in this gorgeous forest, deep woods, loamy and brown. There are roots all around me and I’m seeing the trees growing, and I’m part of them. It didn’t feel sad or happy, just natural, contented, peaceful. I wasn’t gone. I was part of the earth.” Several patients described edging up to the precipice of death and looking over to the other side. Tammy Burgess, given a diagnosis of ovarian cancer at fifty-five, found herself gazing across “the great plain of consciousness. It was very serene and beautiful. I felt alone but I could reach out and touch anyone I’d ever known. When my time came, that’s where my life would go once it left me and that was O.K.”
I was struck by how the descriptions of psychedelic journeys differed from the typical accounts of dreams. For one thing, most people’s recall of their journey is not just vivid but comprehensive, the narratives they reconstruct seamless and fully accessible, even years later. They don’t regard these narratives as “just a dream,” the evanescent products of fantasy or wish fulfillment, but, rather, as genuine and sturdy experiences. This is the “noetic” quality that students of mysticism often describe: the unmistakable sense that whatever has been learned or witnessed has the authority and the durability of objective truth. “You don’t get that on other drugs,” as Roland Griffiths points out; after the fact, we’re fully aware of, and often embarrassed by, the inauthenticity of the drug experience.
This might help explain why so many cancer patients in the trials reported that their fear of death had lifted or at least abated: they had stared directly at death and come to know something about it, in a kind of dress rehearsal. “A high-dose psychedelic experience is death practice,” Katherine MacLean, the former Hopkins psychologist, said. “You’re losing everything you know to be real, letting go of your ego and your body, and that process can feel like dying.” And yet you don’t die; in fact, some volunteers become convinced by the experience that consciousness may somehow survive the death of their bodies.
In follow-up discussions with Bossis, Patrick Mettes spoke of his body and his cancer as a “type of illusion” and how there might be “something beyond this physical body.” It also became clear that, psychologically, at least, Mettes was doing remarkably well: he was meditating regularly, felt he had become better able to live in the present, and described loving his wife “even more.” In a session in March, two months after his journey, Bossis noted that Mettes “reports feeling the happiest in his life.”
How are we to judge the veracity of the insights gleaned during a psychedelic journey? It’s one thing to conclude that love is all that matters, but quite another to come away from a therapy convinced that “there is another reality” awaiting us after death, as one volunteer put it, or that there is more to the universe—and to consciousness—than a purely materialist world view would have us believe. Is psychedelic therapy simply foisting a comforting delusion on the sick and dying?
“That’s above my pay grade,” Bossis said, with a shrug, when I asked him. Bill Richards cited William James, who suggested that we judge the mystical experience not by its veracity, which is unknowable, but by its fruits: does it turn someone’s life in a positive direction?
Many researchers acknowledge that the power of suggestion may play a role when a drug like psilocybin is administered by medical professionals with legal and institutional sanction: under such conditions, the expectations of the therapist are much more likely to be fulfilled by the patient. (And bad trips are much less likely to occur.) But who cares, some argue, as long as it helps? David Nichols, an emeritus professor of pharmacology at Purdue University—and a founder, in 1993, of the Heffter Research Institute, a key funder of psychedelic research—put the pragmatic case most baldly in a recent interview with Science:“If it gives them peace, if it helps people to die peacefully with their friends and their family at their side, I don’t care if it’s real or an illusion.”
Roland Griffiths is willing to consider the challenge that the mystical experience poses to the prevailing scientific paradigm. He conceded that “authenticity is a scientific question not yet answered” and that all that scientists have to go by is what people tell them about their experiences. But he pointed out that the same is true for much more familiar mental phenomena.
“What about the miracle that we are conscious? Just think about that for a second, that we are aware we’re aware!” Insofar as I was on board for one miracle well beyond the reach of materialist science, Griffiths was suggesting, I should remain open to the possibility of others.
“I’m willing to hold that there’s a mystery here we don’t understand, that these experiences may or may not be ‘true,’ ” he said. “What’s exciting is to use the tools we have to explore and pick apart this mystery.”
Perhaps the most ambitious attempt to pick apart the scientific mystery of the psychedelic experience has been taking place in a lab based at Imperial College, in London. There a thirty-four-year-old neuroscientist named Robin Carhart-Harris has been injecting healthy volunteers with psilocybin and LSD and then using a variety of scanning tools—including fMRI and magnetoencephalography (MEG)—to observe what happens in their brains.
Carhart-Harris works in the laboratory of David Nutt, a prominent English psychopharmacologist. Nutt served as the drug-policy adviser to the Labour Government until 2011, when he was fired for arguing that psychedelic drugs should be rescheduled on the ground that they are safer than alcohol or tobacco and potentially invaluable to neuroscience. Carhart-Harris’s own path to neuroscience was an eccentric one. First, he took a graduate course in psychoanalysis—a field that few neuroscientists take seriously, regarding it less as a science than as a set of untestable beliefs. Carhart-Harris was fascinated by psychoanalytic theory but frustrated by the paucity of its tools for exploring what it deemed most important about the mind: the unconscious.
“If the only way we can access the unconscious mind is via dreams and free association, we aren’t going to get anywhere,” he said. “Surely there must be something else.” One day, he asked his seminar leader if that might be a drug. She was intrigued. He set off to search the library catalogue for “LSD and the Unconscious” and found “Realms of the Human Unconscious,” by Stanislav Grof. “I read the book cover to cover. That set the course for the rest of my young life.”
Carhart-Harris, who is slender and intense, with large pale-blue eyes that seldom blink, decided that he would use psychedelic drugs and modern brain-imaging techniques to put a foundation of hard science beneath psychoanalysis. “Freud said dreams were the royal road to the unconscious,” he said in our first interview. “LSD may turn out to be the superhighway.” Nutt agreed to let him follow this hunch in his lab. He ran bureaucratic interference and helped secure funding (from the Beckley Foundation, which supports psychedelic research).
When, in 2010, Carhart-Harris first began studying the brains of volunteers on psychedelics, neuroscientists assumed that the drugs somehow excited brain activity—hence the vivid hallucinations and powerful emotions that people report. But when Carhart-Harris looked at the results of the first set of fMRI scans—which pinpoint areas of brain activity by mapping local blood flow and oxygen consumption—he discovered that the drug appeared to substantially reduce brain activity in one particular region: the “default-mode network.”
The default-mode network was first described in 2001, in a landmark paper by Marcus Raichle, a neurologist at Washington University, in St. Louis, and it has since become the focus of much discussion in neuroscience. The network comprises a critical and centrally situated hub of brain activity that links parts of the cerebral cortex to deeper, older structures in the brain, such as the limbic system and the hippocampus.
The network, which consumes a significant portion of the brain’s energy, appears to be most active when we are least engaged in attending to the world or to a task. It lights up when we are daydreaming, removed from sensory processing, and engaging in higher-level “meta-cognitive” processes such as self-reflection, mental time travel, rumination, and “theory of mind”—the ability to attribute mental states to others. Carhart-Harris describes the default-mode network variously as the brain’s “orchestra conductor” or “corporate executive” or “capital city,” charged with managing and “holding the entire system together.” It is thought to be the physical counterpart of the autobiographical self, or ego.
“The brain is a hierarchical system,” Carhart-Harris said. “The highest-level parts”—such as the default-mode network—“have an inhibitory influence on the lower-level parts, like emotion and memory.” He discovered that blood flow and electrical activity in the default-mode network dropped off precipitously under the influence of psychedelics, a finding that may help to explain the loss of the sense of self that volunteers reported. (The biggest dropoffs in default-mode-network activity correlated with volunteers’ reports of ego dissolution.) Just before Carhart-Harris published his results, in a 2012 paper in Proceedings of the National Academy of Sciences, a researcher at Yale named Judson Brewer, who was using fMRI to study the brains of experienced meditators, noticed that their default-mode networks had also been quieted relative to those of novice meditators. It appears that, with the ego temporarily out of commission, the boundaries between self and world, subject and object, all dissolve. These are hallmarks of the mystical experience.
If the default-mode network functions as the conductor of the symphony of brain activity, we might expect its temporary disappearance from the stage to lead to an increase in dissonance and mental disorder—as appears to happen during the psychedelic journey. Carhart-Harris has found evidence in scans of brain waves that, when the default-mode network shuts down, other brain regions “are let off the leash.” Mental contents hidden from view (or suppressed) during normal waking consciousness come to the fore: emotions, memories, wishes and fears. Regions that don’t ordinarily communicate directly with one another strike up conversations (neuroscientists sometimes call this “crosstalk”), often with bizarre results. Carhart-Harris thinks that hallucinations occur when the visual-processing centers of the brain, left to their own devices, become more susceptible to the influence of our beliefs and emotions.Carhart-Harris doesn’t romanticize psychedelics, and he has little patience for the sort of “magical thinking” and “metaphysics” they promote. In his view, the forms of consciousness that psychedelics unleash are regressions to a more “primitive style of cognition.” Following Freud, he says that the mystical experience—whatever its source—returns us to the psychological condition of the infant, who has yet to develop a sense of himself as a bounded individual. The pinnacle of human development is the achievement of the ego, which imposes order on the anarchy of a primitive mind buffeted by magical thinking. (The developmental psychologist Alison Gopnik has speculated that the way young children perceive the world has much in common with the psychedelic experience. As she puts it, “They’re basically tripping all the time.”) The psychoanalytic value of psychedelics, in his view, is that they allow us to bring the workings of the unconscious mind “into an observable space.”
In “The Doors of Perception,” Aldous Huxley concluded from his psychedelic experience that the conscious mind is less a window on reality than a furious editor of it. The mind is a “reducing valve,” he wrote, eliminating far more reality than it admits to our conscious awareness, lest we be overwhelmed. “What comes out at the other end is a measly trickle of the kind of consciousness which will help us to stay alive.” Psychedelics open the valve wide, removing the filter that hides much of reality, as well as dimensions of our own minds, from ordinary consciousness. Carhart-Harris has cited Huxley’s metaphor in some of his papers, likening the default-mode network to the reducing valve, but he does not agree that everything that comes through the opened doors of perception is necessarily real. The psychedelic experience, he suggests, can yield a lot of “fool’s gold.”
Nevertheless, Carhart-Harris believes that the psychedelic experience can help people by relaxing the grip of an overbearing ego and the rigid, habitual thinking it enforces. The human brain is perhaps the most complex system there is, and the emergence of a conscious self is its highest achievement. By adulthood, the mind has become very good at observing and testing reality and developing confident predictions about it that optimize our investments of energy (mental and otherwise) and therefore our survival. Much of what we think of as perceptions of the world are really educated guesses based on past experience (“That fractal pattern of little green bits in my visual field must be a tree”), and this kind of conventional thinking serves us well.
But only up to a point. In Carhart-Harris’s view, a steep price is paid for the achievement of order and ego in the adult mind. “We give up our emotional lability,” he told me, “our ability to be open to surprises, our ability to think flexibly, and our ability to value nature.” The sovereign ego can become a despot. This is perhaps most evident in depression, when the self turns on itself and uncontrollable introspection gradually shades out reality. In “The Entropic Brain,” a paper published last year in Frontiers in Human Neuroscience, Carhart-Harris cites research indicating that this debilitating state, sometimes called “heavy self-consciousness,” may be the result of a “hyperactive” default-mode network. The lab recently received government funding to conduct a clinical study using psychedelics to treat depression.
Carhart-Harris believes that people suffering from other mental disorders characterized by excessively rigid patterns of thinking, such as addiction and obsessive-compulsive disorder, could benefit from psychedelics, which “disrupt stereotyped patterns of thought and behavior.” In his view, all these disorders are, in a sense, ailments of the ego. He also thinks that this disruption could promote more creative thinking. It may be that some brains could benefit from a little less order.
Existential distress at the end of life bears many of the psychological hallmarks of a hyperactive default-mode network, including excessive self-reflection and an inability to jump the deepening grooves of negative thought. The ego, faced with the prospect of its own dissolution, becomes hypervigilant, withdrawing its investment in the world and other people. It is striking that a single psychedelic experience—an intervention that Carhart-Harris calls “shaking the snow globe”—should have the power to alter these patterns in a lasting way.
This appears to be the case for many of the patients in the clinical trial of psilocybin just concluded at Hopkins and N.Y.U. Patrick Mettes lived for seventeen months after his psilocybin journey, and, according to Lisa, he enjoyed many unexpected satisfactions in that time, along with a dawning acceptance of death.
After the psilocybin session, Mettes spent his good days walking around the city. “He would walk everywhere, try every restaurant for lunch, and tell me about all these great places he’d discovered. But his good days got fewer and fewer.” In March, 2012, he stopped chemo. “He didn’t want to die,” she said. “But I think he just decided that this is not how he wanted to live.”
In April, his lungs failing, Mettes wound up back in the hospital. “He gathered everyone together and said goodbye, and explained that this is how he wanted to die. He had a very conscious death.”
Mettes’s equanimity exerted a powerful influence on everyone around him, Lisa said, and his room in the palliative-care unit at Mt. Sinai became a center of gravity. “Everyone, the nurses and the doctors, wanted to hang out in our room—they just didn’t want to leave. Patrick would talk and talk. He put out so much love.” When Tony Bossis visited Mettes the week before he died, he was struck by Mettes’s serenity. “He was consoling me. He said his biggest sadness was leaving his wife. But he was not afraid.”
Lisa took a picture of Patrick a few days before he died, and when it popped open on my screen it momentarily took my breath away: a gaunt man in a hospital gown, an oxygen clip in his nose, but with shining blue eyes and a broad smile.
Lisa stayed with him in his hospital room night after night, the two of them often talking into the morning hours. “I feel like I have one foot in this world and one in the next,” he told her at one point. Lisa told me, “One of the last nights we were together, he said, ‘Honey, don’t push me. I’m finding my way.’ ”
Lisa hadn’t had a shower in days, and her brother encouraged her to go home for a few hours. Minutes before she returned, Patrick slipped away. “He wasn’t going to die as long as I was there,” she said. “My brother had told me, ‘You need to let him go.’ ”
Lisa said she feels indebted to the people running the N.Y.U. trial and is convinced that the psilocybin experience “allowed him to tap into his own deep resources. That, I think, is what these mind-altering drugs do.”
Despite the encouraging results from the N.Y.U. and Hopkins trials, much stands in the way of the routine use of psychedelic therapy. “We don’t die well in America,” Bossis recently said over lunch at a restaurant near the N.Y.U. medical center. “Ask people where they want to die, and they will tell you at home, with their loved ones. But most of us die in an I.C.U. The biggest taboo in American medicine is the conversation about death. To a doctor, it’s a defeat to let a patient go.” Bossis and several of his colleagues described the considerable difficulty they had recruiting patients from N.Y.U. ’s cancer center for the psilocybin trials. “I’m busy trying to keep my patients alive,” one oncologist told Gabrielle Agin-Liebes, the trial’s project manager. Only when reports of positive experiences began to filter back to the cancer center did nurses there—not doctors—begin to tell patients about the trial.
Recruitment is only one of the many challenges facing a Phase III trial of psilocybin, which would involve hundreds of patients at multiple locations and cost millions of dollars. The University of Wisconsin and the University of California, Los Angeles, are making plans to participate in such a trial, but F.D.A. approval is not guaranteed. If the trial was successful, the government would be under pressure to reschedule psilocybin under the Controlled Substances Act, having recognized a medical use for the drug.
Also, it seems unlikely that the government would ever fund such a study. “The N.I.M.H. is not opposed to work with psychedelics, but I doubt we would make a major investment,” Tom Insel, the institute’s director, told me. He said that the N.I.M.H would need to see “a path to development” and suspects that “it would be very difficult to get a pharmaceutical company interested in developing this drug, since it cannot be patented.” It’s also unlikely that Big Pharma would have any interest in a drug that is administered only once or twice in the course of treatment. “There’s not a lot of money here when you can be cured with one session,” Bossis pointed out. Still, Bob Jesse and Rick Doblin are confident that they will find private money for a Phase III clinical trial, and several private funders I spoke to indicated that it would be forthcoming.
In MacLean’s thinking, one hears echoes of the excitement of the sixties about the potential of psychedelics to help a wide range of people, and the impatience with the cumbersome structures of medicine. It was precisely this exuberance about psychedelics, and the frustration with the slow pace of science, that helped fuel the backlash against them.
Still, “the betterment of well people,” to borrow a phrase of Bob Jesse’s, is very much on the minds of most of the researchers I interviewed, some of whom were more reluctant to discuss it on the record than institutional outsiders like Jesse and MacLean. For them, medical acceptance is a first step to a broader cultural acceptance. Jesse would like to see the drugs administered by skilled guides working in “longitudinal multigenerational contexts”—which, as he describes them, sound a lot like church communities. Others envisage a time when people seeking a psychedelic experience—whether for reasons of mental health or spiritual seeking or simple curiosity—could go to something like a “mental-health club,” as Julie Holland, a psychiatrist formerly at Bellevue, described it: “Sort of like a cross between a spa/retreat and a gym where people can experience psychedelics in a safe, supportive environment.” All spoke of the importance of well-trained guides (N.Y.U. has had a training program in psychedelic therapy since 2008, directed by Jeffrey Guss, a co-principal investigator for the psilocybin trials)* and the need to help people afterward “integrate” the powerful experiences they have had in order to render them truly useful. This is not something that happens when these drugs are used recreationally. Bossis paraphrases Huston Smith on this point: “A spiritual experience does not by itself make a spiritual life.”
When I asked Rick Doblin if he worries about another backlash, he suggested that the culture has made much progress since the nineteen-sixties. “That was a very different time,” he said. “People wouldn’t even talk about cancer or death then. Women were tranquillized to give birth; men weren’t allowed in the delivery room. Yoga and meditation were totally weird. Now mindfulness is mainstream and everyone does yoga, and there are birthing centers and hospices all over. We’ve integrated all these things into our culture. And now I think we’re ready to integrate psychedelics.” He also points out that many of the people in charge of our institutions today have personal experience with psychedelics and so feel less threatened by them.
Bossis would like to believe in Doblin’s sunny forecast, and he hopes that “the legacy of this work” will be the routine use of psychedelics in palliative care. But he also thinks that the medical use of psychedelics could easily run into resistance. “This culture has a fear of death, a fear of transcendence, and a fear of the unknown, all of which are embodied in this work.” Psychedelics may be too disruptive for our society and institutions ever to embrace them.
The first time I raised the idea of “the betterment of well people” with Roland Griffiths, he shifted in his chair and chose his words carefully. “Culturally, right now, that’s a dangerous idea to promote,” he said. And yet, as we talked, it became clear that he, too, feels that many of us stand to benefit from these molecules and, even more, from the spiritual experiences they can make available.
“We are all terminal,” Griffiths said. “We’re all dealing with death. This will be far too valuable to limit to sick people.”
