Toad Venom?


"Toad smoking," which is a substitute for "toad licking," is done by extracting venom from the Sonoran Desert toad of the Colorado River. The toad's venom - which is secreted when the toad gets angry or scared - contains a hallucinogen called bufotenine that can be dried and smoked to produce a buzz.
