Psychoactive Toad Venom
Bufo [new or subgenus: Incilius]
Colorado River Toad; Sonoran Desert Toad; Toad Venom; Otac (the venom)
Several species of toads produce venom that contains psychoactive chemicals, but only Bufo alvarius venom contains 5-MeO-DMT, and in high enough quantities to smoke directly for effect. The venom of some Bufo species, including B. alvarius, contains trace amounts of bufotenin and some may also contain toxic chemicals. Bufo toad venom is poisonous if eaten.
