Artaud received a grant to travel to Mexico, where he met his first (Mexican) Parisian friend, the Painter Federico Cantú in 1936 when he gave lectures on the decadence of Western civilization. He also studied and lived with the Tarahumaran people and experimented with peyote, recording his experiences, which were later released in a volume called Voyage to the Land of the Tarahumara. The content of this work closely resembles the poems of his later days, concerned primarily with the supernatural. Artaud also recorded his horrific withdrawal from heroin upon entering the land of the Tarahumaras; having deserted his last supply of the drug at a mountainside, he literally had to be hoisted onto his horse, and soon resembled, in his words, "a giant, inflamed gum". Artaud would return to opiates later in life.
