Mescaline Mexico. Europeans noted use of peyote in Native American religious ceremonies upon early contact, notably by the Huichols in Mexico. Other mescaline-containing cacti such as the San Pedro have a long history of use in South America, from Peru to Ecuador. In traditional peyote preparations, the top of the cactus is cut off, leaving the large tap root along with a ring of green photosynthesizing area to grow new heads. These heads are then dried to make disc-shaped buttons. Buttons are chewed to produce the effects or soaked in water to drink. However, the taste of the cactus is bitter,
Isoproscaline mechanism of action shared by all of the hallucinogenic tryptamines and phenethylamines. The toxicity of isoproscaline is not known. Isoproscaline is unscheduled and unregulated in the United States, however because of its close similarity in structure and effects to mescaline, possession and sale of isoproscaline may be subject to prosecution under the Federal Analog Act. In the UK its highly likely that this compound would be covered by the "phenylethylamine amendment" to the misuse of drugs act likely rendering it (probably) a Class A controlled drug. Isoproscaline Isoproscaline or 4-(i)-propoxy-3,5-dimethoxyphenethylamine is an analogue of mescaline. It is closely related to
