On March 4, 2014, the results of our completed study of the therapeutic use of lysergic acid diethylamide (LSD) to treat anxiety associated with advanced-stage illness were published online in the peer-reviewed Journal of Nervous and Mental Disease. This is the first study of the therapeutic use of LSD in humans in over 40 years. The double-blind, placebo-controlled pilot study in 12 subjects found statistically significant reductions in trait anxiety following two LSD-assisted psychotherapy sessions. The results also indicate that LSD-assisted psychotherapy can be safely administered in these subjects, and justify further research. Eleven of the 12 subjects had never used LSD previously. “The study was a success in the sense that we did not have any noteworthy adverse effects,” reports Principal Investigator Peter Gasser, M.D.. “All participants reported a personal benefit from the treatment, and the effects were stable over time.” Download the paper . . .
