The Varieties of Psychedelic Experience

Book excerpt: “This is a sober and authoritative appraisal of what is currently the most controversial development in the study of human personality. The authors have spent a combined fifteen years in closely controlled and thoroughly documented research with nonaddictive psychedelic drugs, and most particularly with LSD-25 before it was declared illegal. Avoiding the starry-eyed claims and the fiery denunciations of the pro and con factions, this book sheds much new light on the possibilities and limitations of these drugs, as well as on the techniques for working with them.”-Publisher.
