“Psychedelics may still be a valuable treatment option,” said Balázs Szigeti, PhD, a clinical data scientist at UCSF’s Translational Psychedelic Research Program and the co-first author of a new paper which found that drugs like L*D and psilocybin are no better than antidepressants when it comes to treating major depression. “But if we want to understand their true benefits, we have to compare them fairly — and when we do that, the advantage over standard antidepressants is much smaller than many people, including myself, expected.”
Szigeti's study focuses on a long-standing challenge in psychedelic research: blinding. In standard drug trials, the study is blinded, meaning neither patients nor researchers know who receives the active treatment and who gets a placebo. Psychedelic studies are hard to blind because the drugs cause strong effects.
In psychedelic studies, placebo groups often improve less, partly because participants may realize they did not receive the drug. In antidepressant trials, placebo groups tend to improve more, possibly because more placebo recipients believe they received the active therapy. This difference can make psychedelics appear more effective.
