A number of studies examining the use of LSD to treat a variety of disorders, including alcoholism, were conducted in the 1950s, ’60s and ’70s.
In a new analysis, Norwegian researchers examined six studies of LSD and alcoholism that were conducted in the United States and Canada between 1966 and 1970.
The analysis of data from the 536 patients in the studies showed that a single dose of LSD helped heavy alcoholics quit and reduced their risk of resuming drinking, according to the meta-analysis appearing online March 8 in the Journal of Psychopharmacology.
Patients who received a full dose of the controversial drug did the best. On average, 59 percent of those patients showed a clear improvement, compared with 38 percent of patients in other groups, the Norwegian University of Science and Technology researchers said.
