Lysergide Treatment of Schizophrenic and Nonschizophrenic Alcoholics; A Controlled Evaluation

This historic study (1970; n=75) used LSD (500μg) in the treatment of alcoholics and found that those without schizophrenia (about 2/3 of patients) responded better.

Abstract

Of 75 alcoholics treated with lysergide, 23 were diagnosed as schizophrenics. The nonschizophrenics had better reactions to the drug and more of them were abstinent at a 1-year follow-up than the schizophrenics and than alcoholics treated by other methods.

Research Summary of 'Lysergide Treatment of Schizophrenic and Nonschizophrenic Alcoholics; A Controlled Evaluation'

Introduction

Earlier research on lysergide (LSD) as a treatment for alcoholism began in the 1950s with Hoffer and Osmond and emphasised producing a controlled altered state that might motivate abstinence. Over the next decade a number of reports—many from Canadian groups—described promising therapeutic effects, but several were criticised for weak methodology, chiefly lack of appropriate controls, blind assessment, and standardised outcome measurement. Subsequent controlled projects produced mixed results, with some early controlled trials finding no differences and others reporting benefits, highlighting uncertainty about whether observed changes were transient or durable once patients returned to ordinary life. Tomsovic and colleagues initiated this study (data collection September 1965 to April 1968) to provide a controlled evaluation of adding a single, high-dose lysergide experience to an existing 90-day Alcoholic Rehabilitation Programme. Although the original plan was to have comparable proportions of schizophrenic and nonschizophrenic alcoholics across treated and control groups, preliminary analyses drew attention to differential effects by psychiatric diagnosis and prompted a focussed comparison of outcomes for schizophrenic versus nonschizophrenic patients. The investigators acknowledged substantial methodological challenges in evaluating a spectacular mind‑altering drug and aimed to report one-year follow-up outcomes, psychometric measures of the acute experience, and the incidence of post‑treatment recrudescence.

Single Oral Lysergide (LSD 500 µg) in Inpatient Alcoholic Rehabilitation: Controlled Evaluation with Schizophrenic Sub-Analysis (Tomsovic & Edwards 1970)

Controlled evaluation of single oral lysergide (LSD) 500 µg in an inpatient 90-day Alcoholic Rehabilitation Programme (Q J Stud Alcohol 1970 Dec; Tomsovic M, Edwards RV; PMID 5490826). n=75 volunteers received lysergide; among these, 23 were classified as schizophrenic. Volunteers paired with contemporaneous admissions; at day 45, one of each pair assigned to lysergide by coin toss (partially randomised). Control group I: volunteers who did not receive lysergide or received placebo substitute. Control group II: routine programme participants who had completed before the project or did not volunteer. Session: single oral 500 µg lysergide in specially furnished room (colourful drapes, pictures, music); patient-chosen nursing assistant present non-directively for 7 h; administering psychiatrist made intermittent visits; preparatory readings and debrief the next day. Primary outcome: drinking control (Drinking Adjustment Scale) at 3, 6, and 12 months; validation by spouses/informants. Secondary: Blewett & Chwelos Scales (acute/subacute reactions); subjective session classification ("good"/"moderate"/"poor"); rates of recrudescence (vivid post-session recurrences). Schizophrenic vs non-schizophrenic sub-analyses. No registration (pre-registration era, 1970). CT.gov: 0 hits.
