Long before Timothy Leary urged a generation to "tune in, turn on and drop out," lysergic acid diethylamide (or LSD) was being used by researchers committed to understanding the workings of the human mind. Discovered in 1943 by Swiss chemist Albert Hofmann, LSD was hailed as a powerful tool for the treatment of alcoholism and drug addiction and to provide a window into schizophrenia and other mental illnesses. While researchers were establishing the medical benefits of LSD, others promoted the drug as a powerful tool for mental exploration and self-understanding. With thoughtful interviews, beautiful music and stunning cinematography, Hofmann's Potion is an invitation to look at LSD with a more open, compassionate mind.
