The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
The study that I'd like to highlight is a fairly recent one. It was published in may of 2021 in Journal of the American Medical Association Psychiatry, so JAMA Psychiatry, and it's entitled, "Effects of Psilocybin Assisted Therapy "on Major Depressive Disorder, a Randomized Clinical Trial."
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The study that I'd like to highlight is a fairly recent one. It was published in May of 2021 in Journal of the American Medical Association Psychiatry, so JAMA Psychiatry, and it's entitled, "Effects of Psilocybin-Assisted Therapy on Major Depressive Disorder: A Randomized Clinical Trial." Basically, what they did was they screened for patients to come into the clinic. These were people that suffered from major depressive disorder and administered either one or two rounds of psilocybin. Typically, it was 20 milligrams per kilogram of body weight, so it depends on body weight. What's really striking about this study, is that there was a very significant improvement in mood, and affect, and relief from depressive symptoms in anywhere from 50 to 70% of the people that were subjects in the study who received the psilocybin treatment.
