Psilocybe cubensis grows worldwide in tropical and subtropical regions, including Central and South America, Southeast Asia, and Oceania. The mushroom prefers moist, fertile soils and contains the psychoactive substance psilocybin, which is currently being investigated as an active ingredient in the treatment of treatment-resistant depression.
