Jumping into our new column, Backyard Entheogens is Bufo alvarius, the Sonoran Desert Toad. The venom of Bufo alvarius is a potent source of the naturally occurring hallucinogenic 5MeO-DMT used by ancient peoples and is at the origin of the toad-sucking myth. Psychonauts beware: Toad tripping can range from bliss to terror. Discover the ritualistic and modern applications of this visionary compound and many more psychedelics in Backyard Entheogens.
