The figure of the 'mad scientist' associated with unethical LSD experiments persists in public imagination even as psychedelic stigma fades. Scientists and humanities scholars have tried to separate careful from ignorant use of psychedelics, but historical examples from Canada show that knowledgeable psychedelic therapists also used LSD on vulnerable populations in correctional facilities. Enthusiasm about the drug's potential led experienced therapists to apply it in institutional settings like prisons. This history reveals how modern industrial society's institutional context shaped past psychedelic therapy and suggests today's therapists must consider how this broader context affects their work.
In 1962, the Addiction Research Foundation of Ontario conducted the first double-blind randomized controlled trial of LSD therapy for alcoholism, finding it ineffective. Critics argued the Toronto researchers were biased against LSD, using an anti-therapeutic method—restraining patients to a bed, administering an unusually large dose, and providing minimal support—which some called a form of torture. Historians have dismissed the study as flawed or naïve. This paper reexamines the Toronto psychiatrists, showing they were actually enthusiastic about LSD and had their own sophisticated expertise, differing from the Saskatchewan psychedelic approach. The study's problems arose not from bias or incompetence but from the tension between LSD therapy and controlled trial methodology.
Psychedelic drugs show promise for treating psychological disorders, but understanding how they work requires mechanistic evidence—reasoning about the causal pathways behind their effects. This thesis surveys past and current proposals, identifying two broad views: “mind-manifesting” views, where psychedelics help by revealing unconscious content, and “mind-modifying” views, where they disrupt rigid thought patterns and boost psychological flexibility. These views are often conflated in research, and the author argues they must be clearly distinguished to better understand psychedelic benefits. The work then explores using “psychedelic testimony” to help separate these views.
