Altered minds: mescaline’s complicated history

Pharmacologists gave mescaline a fair trial. In the early and mid-twentieth century, it seemed more than plausible that the fashionable hallucinogen could be tamed into a therapeutic agent. After all, it had profound effects on the human body, and had been used for centuries in parts of the Americas as a gateway to ceremonial spiritual experience. But this psychoactive alkaloid never found its clinical indication, as science writer Mike Jay explains in Mescaline, his anthropological and medical history. In the 1950s, the attention of biomedical researchers abruptly switched to a newly synthesized molecule with similar hallucinogenic properties but fewer physical side effects: lysergic acid diethylamide, or LSD. First synthesized by Swiss scientist Albert Hofmann in 1938, LSD went on to become a recreational drug of choice in the 1960s hippy era. And, like mescaline, it teased psychiatrists without delivering a cure.
