Today's guest is Susannah Cahalan, whose new book is The Acid Queen, a biography of Rosemary Woodruff Leary—muse, fugitive, and heavily indicted co-conspirator in Timothy Leary's psychedelic revolution. She talks with Reason's Nick Gillespie about hippie communes, outlaw drug smuggling, the war on drugs—and how the '60s counterculture, in its best moments, ran experiments in radical individualism, using personal freedoms to build voluntary communities rooted in altered consciousness and aesthetic liberation. The Acid Queen helps explain how the personal became the political, why libertarians should care about the messy legacy of the counterculture, and what comes next in drug policy, especially regarding psychedelics. This conversation was recorded at a live event in New York City. Go here to find out about upcoming events.
