Peyote is a tiny cactus that has had a giant impact on history and culture. It is one of the most ancient hallucinogens - finds near the Texas-Mexico border indicate that humans have been consuming this Plant of the Gods for over 6000 years. Many credit Aldous Huxley's 1954's book "The Doors of Perception" - based on his experiences with mescaline, the most active alkaloid in peyote - as launching the Psychedelic Renaissance. And this cactus and this alkaloid and this book impacted The Beatles, The Doors and The Who as well. This episode tells that story.
