This FDA film explores the history of hallucinogenic drugs, and specifically the effects and therapeutic uses of lysergic acid diethylamide (LSD). Combining graphics that suggest a hallucinogenic experience, snippets of interviews with users (who explain their reasons for taking the drug) and doctors, and taped sessions of research with volunteers, the film delves into the destructive as well as possible positive uses of the drug.
