This book is fascinating. It is not an "I like trippin' and listenin' to the Dead" book. It is a very thorough, interesting account of the work of two very intelligent and thoughtful people in the area of psychedelic drugs and their influence on/application to human life. Here's a quote that gives some idea of the orientation of the book: of marijuana (not a phenethylamine, and thus, not really addressed fully in the book), Shulgin writes, "I have chosen not to use marijuana, as I feel the light-headed intoxication and benign alteration of consciousness does not adequately compensate for an uncomfortable feeling that I am wasting time." Of psychedelics, he writes, "the potential of the psychedelic drugs to provide access to the interior universe, is, I believe, their most valuable property." This isn't a book about seeing jerry-bears and setting up clandestine labs. It's an introduction to a new way of exploring one's relationship to the rest of the universe. It is wonderful and an invaluable resource to all who are willing to try to deal with this piece of the puzzle.
