has been illegal in the United States for more than 40 years. But Mr. Mihai, who had just finished treatment for Stage 3 Hodgkin’s lymphoma, was participating in a study looking at whether the drug can reduce anxiety and depression in cancer patients. Throughout that eight-hour session, a psychiatrist and a social worker from NYU Langone Medical Center stayed by his side.
Published Thursday, the results from that study, and a similar small, controlled trial, were striking. About 80 percent of cancer patients showed clinically significant reductions in both psychological disorders, a response sustained some seven months after the single dose. Side effects were minimal.
In both trials, the intensity of the mystical experience described by patients correlated with the degree to which their depression and anxiety decreased.
The studies, by researchers at New York University, with 29 patients, and at Johns Hopkins University, with 51, were released concurrently in The Journal of Psychopharmacology. They proceeded after arduous review by regulators and are the largest and most meticulous among a handful of trials to explore the possible therapeutic benefit of psilocybin.
Dr. Jeffrey Lieberman, a past president of the American Psychiatric Association, and Dr. Daniel Shalev of the New York State Psychiatric Institute are among leaders in psychiatry, addiction medicine and palliative care who endorsed the work. The studies, they wrote, are “a model for revisiting criminalized compounds of interest in a safe, ethical way.”
If research restrictions could be eased, they continued, “there is much potential for new scientific insights and clinical applications.”
Psilocybin trials are underway in the United States and Europe for alcoholism, tobacco addiction and treatment-resistant depression. Other hallucinogens are also being studied for clinical application. This week, the Food and Drug Administration approved a large-scale trial investigating MDMA, the illegal party drug better known as Ecstasy, for post-traumatic stress disorder.
