This the story of LSD, as told by Albert Hofmann, PhD. Hofmann follows the path of LSD as a promising psychiatric medicine to its use as a recreation drug, most popularized in the late 1960s and very early 1970s, especially in the United States. In the book, Hofmann talks about how he discovered LSD. He was researching medically useful ergot alkaloid derivatives to assist women in the birthing process. Hofmann talks about how he first synthesized LSD in Switzerland 1938, from ergotamine, a chemical from the fungus ergot. He then discovered its psychoactive effects in 1943 by accidentally ingesting an unknown amount of the chemical. He describes his bike ride back to his home, after ingesting the LSD for the first time. In the book, Hofmann talks about LSD in the context of psychiatry, the natural precursors to LSD (LSA), and his meeting with Aldous Huxley. Hofmann also talks about the LSD experience in his own words. In the version I have which was given to me by the Multidisciplinary Association for Psychedelic Studies in ~2010, the forward of the book is authored by Stanislav Grof, who is a psychedelic giant in his own right. If LSD is your favorite psychoactive substance or you are a psychedelic enthusiast, this is a must-read.
