The Substances & The Research

Psilocybin

The active compound in “magic mushrooms.” The study by Davis et al. (2021) in JAMA Psychiatry showed that 2 psilocybin sessions reduced depression symptoms in 71% of participants, with results lasting at least 4 weeks. Carhart-Harris et al. (2021) in the New England Journal of Medicine confirmed these findings.

MDMA

The only psychedelic substance already used legally (esketamine/Spravato, FDA 2019) for treatment-resistant depression. It acts in hours, not weeks like conventional antidepressants.
