LSD before Leary: Sidney Cohen's Critique of 1950s Psychedelic Drug Research

Summary

In 1962, Sidney Cohen highlighted the dangers of LSD, a drug initially celebrated for its potential to induce mystical experiences. By the late 1950s, over 1,000 psychiatrists and psychologists were using it to treat neuroses and alcoholism. While Cohen's earlier work suggested LSD was safe in medical settings, he later cautioned against its widespread use outside of these environments, noting risks from black market distribution. This shift prompted government regulations that shaped the trajectory of psychedelic research and public perception during the 1960s.

Abstract

In 1962 Sidney Cohen presented the medical community with its first warning about the dangers of the drug LSD. LSD had arrived in the United States in 1949 and was originally perceived as a psychotomimetic capable of producing a model psychosis. But in the mid 1950s intellectuals in Southern California redefined LSD as a psychedelic capable of producing mystical enlightenment. Though LSD was an investigational drug, authorized only for experimental use, by the late 1950s psychiatrists and psychologists were administering it to cure neuroses and alcoholism and to enhance creativity. Cohen's 1960 study of LSD effects concluded that the drug was safe if given in a supervised medical setting, but by 1962 his concern about popularization, nonmedical use, black market LSD, and patients harmed by the drug led him to warn that the spread of LSD was dangerous. The subsequent government crackdown and regulation of LSD preceded the 1960s drug movement and was prompted by medical, not social, concerns.
