A single dose of the psychedelic drug LSD may ease generalized anxiety disorder for months, a clinical trial has found.
The trial results, published Thursday (Sept. 4) in JAMA, include data from 194 people with moderate to severe anxiety across the U.S. The study compared these participants' responses to different doses of LSD against a placebo treatment. It found that the drug alleviated symptoms in many patients for at least three months after just one exposure.
