Also known as MESCALINE, 3,4,5-TRIMETHOXYPHENETHYLAMINE

Mescaline ranks among humanity's most ancient known psychedelics, being the chief psychoactive constituent of the peyote cactus, which native peoples of the southwestern part of the United States and northern Mexico have long taken ceremonially. Every other psychedelic tends to be rated against it in both strength and duration, and a typical adult becomes affected near the 300 milligram mark.
