Source term: bullroarer
"Sapo del amanecer," the toad of dawn — Rettig's name for Bufo alvarius, the Sonoran Desert toad whose venom yields the 5-MeO-DMT used in the ceremony.
In the Vice series Miscelánea Mexicana, the episode "El profeta del sapo" follows the Guadalajara doctor Octavio Rettig into the Sonoran desert and to Isla Tiburón, where, as a Seri elder sings, he administers the venom of the Sonoran Desert toad, Bufo alvarius, whose secretion contains the potent psychedelic 5-MeO-DMT. Rettig, author of the 2016 book Bufo Alvarius: el sapo del amanecer ("the toad of dawn"), promoted the smoking of toad venom as an ancestral medicine of the Seri, or Comcaac, of Sonora. There is no archaeological or ethnographic record of such ceremonial use; the early ethnobotanists Richard Felger and Mary Moser found toads inconsequential in Seri culture. Researchers trace the modern practice instead to a 1984 booklet, Bufo alvarius: The Psychedelic Toad of the Sonoran Desert, written under the pseudonym Albert Most by Ken Nelson, and to a Comcaac foundation, OTA.C, which around 2011 introduced toad venom as a contemporary treatment for methamphetamine addiction rather than a revival of any old rite. When The New Yorker profiled Rettig in 2022 as "the pied piper of psychedelic toads," the few Seri who spoke of an ancient toad-smoking tradition described it as something they had only heard of; a Seri historian, Alberto Mellado Moreno, called it "speculative even for us." A bullroarer is reported to appear in the filmed ceremony, spun over the participants, an instrument that belongs to this contemporary practice and to no documented Seri tradition.
There is no ethnographic record of the ceremonial consumption of the toad secretion among traditional peoples, although the practice of smoking the "sacred medicine of the toad" spread all over the globe.
