This week’s books podcast promises to be a trip. Sam is joined by Mike Jay to talk about the history of mescaline — a psychedelic drug whose influence goes from the earliest South American civilisations through the 19th-century Indian Wars up to W B Yeats, Aleister Crowley and (of course) Aldous Huxley and Hunter S Thompson. Does tripping balls tell us anything profound about human consciousness? How come Mexico got all the good drugs? And why did Aldous Huxley lie about his trousers?
Presented by Sam Leith.
