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.”
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?”
“There is such a sense of authority that comes out of the primary mystical experience that it can be threatening to existing hierarchical structures,” Roland Griffiths, a psychopharmacologist at Johns Hopkins University School of Medicine, 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.”
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.
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.”
