Don Lattin recalls the creation of the Harvard Psilocybin Project (Harvard Psychedelic Club) in 1960-1961 by a group of four students interested in studying the effects of psychedelic drugs.  The students, Timothy Leary, Andrew Weil, Huston Smith, and Richard Alpert (Ram Dass) would later introduce Americans to mind expanding drugs, alternative healing and medicine, and world religions.  Don Lattin discussed his book at the Harvard Book Store in Cambridge, Massachusetts.
