A proposal advocating research into the long-lasting effects of d-lysergic acid diethylamide (LSD) on normal people. In addition to its use in psychotherapy, there have been reports of experimental subjects who claim lasting beneficial effects attributable to the LSD experience. An experiment is suggested that would attempt to measure any long-lasting changes in attitudes, values, and communicative ability resulting from the administration of LSD. In particular, the measures would concentrate on changes in closed-mindedness as reflected by scales of dogmatism, opinionation, and ethnocentricity. A history of LSD-like drugs is provided, along with a description of some of the more frequent phenomena experienced under their influences.
