Abstract

A 6‐week study comparing the psychedelic psilocybin with the antidepressant escitalopram found no significant difference in antidepressant effects in patients with moderate to severe depression. Some secondary outcome measures favored psilocybin, but those analyses were not adjusted for multiple comparisons. Study results were published in the April 15, 2021 issue of The New England Journal of Medicine .
