Book excerpt: Combining literature, social history, and personal experience, author Robert J. Campbell traces the birth, downfall, and legacy of the innovative, playful, and spontaneous counterculture launched in 1960s Haight-Ashbury. In a lively writing style, Campbell describes the discovery of LSD, its slow adoption, and the promotion of it by Timothy Leary and Ken Kesey, who each became missionaries for the drug. Campbell relates how LSD allowed users to enhance the perception of alternative realities and describes its wide-scale use in the Haight-Ashbury District of San Francisco from 1964 to 1967 that led to imaginative and creative change, including collaborative behavior, a new way of looking at the world, acid rock, and a host of other paradigm shifts. Haight-Ashbury, Psychedelics, and the Birth of Acid Rock concludes by examining the inherent dangers of constant drug use as well as the positive legacy of the 1960s, including a focus on health food, cooperative living arrangements, recycling, battling climate change, free medical help, and personal responsibility. The book incorporates ideas from a broad range of disciplines for general readers for a unique and fresh look at this impactful era.
