"The Harvard Psychedelic Club" is a non-fiction book by Don Lattin that explores the history of the psychedelic movement in the United States during the 1960s. The book focuses on the lives and work of four key figures in the movement: Timothy Leary, Richard Alpert (aka Ram Dass), Andrew Weil, and Huston Smith. Lattin follows the personal and professional journeys of these four men as they experiment with LSD and other mind-altering drugs, form friendships and rivalries, and ultimately shape the course of the psychedelic movement. Along the way, Lattin also examines the social and political context in which the movement emerged, including the countercultural movements of the era and the changing attitudes towards drugs and spirituality in American society. Through a combination of interviews, archival research, and personal anecdotes, Lattin provides a rich and engaging account of a pivotal moment in American cultural history.
