The Harvard Psychedelic Club is not only a great read, it's also an unforgettable head trip. Lattin weaves a masterful tale of

1960s-style spirituality, professional jealousy, and out-of-body experiences. Lattin has done his homework and it shows. Read this book and expand your mind. No hallucinogenics required. (Eric Weiner, author of The Geography of Bliss )

A revealing account of four iconic personalities who helped define an era, sowed seeds of consciousness, and left indelible marks in the lives of spiritual explorers to this day. The Conclusion is alone worth the price of the book. (Dan Millman, author of The Peaceful Warrior )

With care and considerable humor, Don Lattin shows us how the interwoven relationships of four charismatic visionaries contributed to the expansion of mind that changed American culture forever. The way we eat, pray, and love have all been conditioned by their lives and teachings. (Mirabai Bush, co-founder and Senior Fellow of the Center for Contemplative Mind in Society, co-author (with Ram Dass) of Compassion in Action )

I suspect I'm not the only person who thought the psychedelics-at-Harvard story had been pretty well settled, but Lattin's work has widened my perspective considerably. By focusing on Huston Smith and Andrew Weil as well as Leary and Alpert, he's created a stimulating and thoroughly engrossing read.
