Tulum is experiencing an explosion of people taking Bufo Alvarius. Also called “speed-toading,” it involves smoking the milked poison of the Sonoran Desert toad in a glass pipe and is considered to be the most powerful hallucinogen in the world. Now, growing numbers of psychedelic tourists are traveling to Tulum where Bufo ceremonies are legal, in search of a life-changing experience. However, there are many reports of profoundly negative experiences, lasting psychosis and allegations of sexual assault during ceremonies.
