Psilocybin-assisted therapy has emerged as a promising treatment for major depressive disorder, but little attention has been paid to the psychotherapy that adjoins psilocybin. Providing an adjunctive psychotherapy that is manualized and evidence-based may make psilocybin treatment more acceptable, effective, and disseminable. We examined the acceptability, feasibility, and clinical outcomes of...

Forming a vital component of prehistorical and aboriginal culture and belief systems, hallucinogens were ultimately condemned and repressed by evolving civilizations, only to the “rediscovered” in the 20th century. Of compelling interest to...
