The clinical trials at N.Y.U.—a second one, using psilocybin to treat alcohol addiction, is now getting under way [newyorker.com]—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.
The results taste orange.
