Most of studies were conducted double-blind and placebo-controlled, a few were single-blind and placebo-controlled. In total, 506 medically healthy subjects with no personal or familial Axis I psychotic spectrum disorders were administered at least one dose of psilocybin (115-350 µg/ kg po) (n=250), ketamine (6-12 µg /kg min i.v.) (n=149) or MDMA (1.5-1.7mg/kg) (n=107).
It is planned do an in depth statistical analysis of the acute, post-acute and long-term effects.
