It belongs to a group known as the substituted tryptamines which act by stimulating serotonin receptorsin the brain.
5-MeO DMT is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and at least one psychoactive toad species, the Sonora Desert toad. Like its close relatives DMT and bufotenin, it has been used as an entheogen in South America.
