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 trying to understand the human mind. This documentary is a fascinating look at the story of "acid" before it hit the streets.  Featuring interviews with many LSD pioneers, Hofmann's Potion is much more than a simple chronicle of the drug's early days. With thoughtful interviews, beautiful music and stunning cinematography, it is an invitation to look at LSD, and our world, with a more open, compassionate mind.
