While voters are still grappling with the legality of psychedelics, regular people (as usual) are taking things into their own hands. Make that, their mouths. In late October, the National Park Service posted a message on Facebook cautioning people not to lick toads that produce psychedelic-like effects in humans. They called it a “toad-ally terrifying” practice. There are several species of toads that secrete psychoactive compounds, but one of the most well-known is Bufo alvarius. Commonly called the Colorado River toad, found in northern Mexico and the US Southwest, it is among the largest North American toads, measuring nearly 7 inches. The toad produces DMT derivatives which are fatal to some animals when ingested, but can help humans along on their psychedelic journey — if it doesn’t make you sick. It’s unclear what’s behind the uptick in toad licking, but recently some celebrities, like Mike Tyson, have spoken about their psychedelic trips. Regardless, the toad is considered a threatened species in several states, so it might be best to find a different source for your finger licking.
