Summary
AI-generated from the abstractSubstituting a tap water placebo for lysergic acid diethylamide (LSD-25) produced effects in participants that were similar to those of the drug itself, indicating that placebo responses can mimic hallucinogen-induced experiences. The study reports that a notable proportion of subjects reported subjective changes after receiving the placebo, and the authors suggest that psychological factors, including expectation and suggestion, play a significant role in the effects attributed to LSD.
