The vets drank psilocybin, a psychoactive compound found in some mushrooms, put on blindfolds to shut out distractions and lay down. The retreat was organized and paid for by the Heroic Hearts Project, a nonprofit that's helped more than 1,000 U.S. veterans with combat-related PTSD access psychedelics. Them seeking this type of unauthorized therapy is just another indication on why we need to study this further and get it to a safe and effective medical environment.
