All of these cravings, high or low, are nicely met by the plant kingdom, which has various psychoactive agents that seem almost tailored to the neurotransmitter systems and receptor sites in our brains. (They are not, of course; they have evolved to deter predators or sometimes to attract other animals to eat a plant’s fruit and disseminate its seeds. Nevertheless, one cannot repress a feeling of wonder that there should be so many plants capable of inducing hallucinations or altered brain states of many kinds.)1
Richard Evans Schultes, an ethnobotanist, devoted much of his life to the discovery and description of these plants and their uses, and Albert Hofmann was the Swiss chemist who first synthesized LSD-25 in a Sandoz lab in 1938.

By the 1890s, Westerners were also beginning to sample mescal, or peyote, previously used only as a sacrament in certain Native American traditions.4
As a freshman at Oxford, free to roam the shelves and stacks of the Radcliffe Science Library, I read the first published accounts of mescal, including ones by Havelock Ellis and Silas Weir Mitchell. They were primarily medical men, not just literary ones, and this seemed to lend an extra weight and credibility to their descriptions. I was captivated by Weir Mitchell’s dry tone and his nonchalance about taking what was then an unknown drug with unknown effects.
At one point, Mitchell wrote in an 1896 article for the
