5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine) is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and at least one toad species, the Sonora Desert toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America.^[1]
