Trichocereus peruvianus, a.k.a.
Peruvian Torch
T. peruvianus is a mescaline-bearing cactus comparable to Trichocereus pachanoi (San Pedro). T. peruvianus, like its cousin San Pedro, is a large, fast-growing, columnular cactus, growing 10 feet tall or more, and about 7 inches in diameter. It is easy to cultivate at home in a pot. It bears beautiful night-blooming flowers. T. peruvianus has larger spines than San Pedro.
T. peruvianus usually has a higher mescaline content than San Pedro. Also, since T. peruvianus contains extremely low quantities of other psychoactive alkaloids, it could be said to give a "purer" mescaline experience than San Pedro or Peyote (Lophophora williamsii). It should be noted that T. peruvianus, like San Pedro but unlike Peyote, is legal to own and cultivate in the United States. It is illegal to use for its psychoactive purposes or to process it for mescaline.
