"In the recent Imperial trial, the first with psilocybin in depression, 20 patients with treatment-resistant form of the disorder were given two doses of psilocybin (10 mg and 25 mg), with the second dose a week after the first."
I've always been under the impression any anti-depressant effect of psilocybin would be primarily based in psychology, but at that low of a dosage it seems unlikely which makes one wonder if there is also a significant biological basis.
But that said, I don't understand the desire for others to control what people put into their own bodies in the first place.
