Mescaline became popular after Aldous Huxley wrote about it in The Doors of Perception (1954) and the word “psychedelic” was coined, but its story begins in deep prehistory. Author Mike Jay follows its trail from the pre-Columbian use of the peyote cactus in Mexico to its adoption by the Plains Indian tribes in their forced captivity on the reservations, and its eventual discovery by Western science.
