Persuasive Substances: Transdisciplinary Rhetorics of Drugs and Recovery in the Rise and Decline of Psychedelic Therapy

This dissertation is a rhetorical-historiographic analysis of the emergence and dissolution of a model of therapy, one that showed promise in the 1950s as a treatment for a deadly disease (alcoholism) using a recently developed pharmaceutical drug (LSD-25). By the time this treatment model, called “psychedelic therapy,” was fully developed and ready to be tested, the rhetoric surrounding LSD in the 1960s public sphere had already turned mainstream psychiatry against the drug. Psychedelic therapy became rhetorically inextricable from the counterculture that grew out of its fringes, although its basic principles were actually borrowed from the widely-accepted Alcoholics Anonymous recovery movement. Moreover, the therapy only worked if the patient took the drug in a context designed to facilitate a particular type of experience, akin to a spiritual conversion. This method flew in the face of psychiatry’s insistence on double-blind placebo-controlled trials, which could only account for the drug’s strictly biochemical effects, regardless of therapeutic context. Through my analysis of archival sources, letters, conference proceedings, and research publications, I argue that psychedelic therapy’s failure to gain legitimacy despite its early success indicates how attributions of  rhetorical action (or lack thereof) serve to mark out the boundaries of discursive arenas. These demarcations of rhetorical legitimacy thus allow for disciplinary legitimacy, even while the techniques, strategies, and materials of particular rhetorical appeals circulate among disciplines and other arenas without regard for these limits of legitimate persuasion. A drug may undeniably affect a person’s behavior, but to assert that the drug is persuasive will necessarily raise questions of legitimacy that must be resolved before it can be incorporated into a set of disciplinary practices.
