Peyote (Lophophora williamsii) is a small, spineless cactus whose native region extends from the southwestern United States (including the states of Texas and New Mexico) through central Mexico. It has been used for centuries for the psychedelic effects experienced when it is ingested.
The cactus flowers sporadically, producing small pink fruit, similar in appearance to a chili pepper, which can be very delectable and sweet-tasting when eaten. Peyote contains a large spectrum of phenethylamine alkaloids, the principal of which is mescaline, also found in many other cactus species like San Pedro and Peruvian Torch. All Lophophora species are extremely slow growing, often taking up to thirty years to reach flowering age (at about the size of a golf ball, not including root) in the wild. Due to this slow growth and over-harvesting by collectors, peyote is considered to be in danger of extinction in the wild.
