Mescaline Mescaline Mescaline (3,4,5-trimethoxyphenethylamine) is a naturally occurring psychedelic alkaloid of the phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin. It occurs naturally in the peyote cactus ("Lophophora williamsii"), the San Pedro cactus ("Echinopsis pachanoi"), the Peruvian torch ("Echinopsis peruviana"), and other members of the Cactaceae plant family. It is also found in small amounts in certain members of the Fabaceae (bean) family, including "Acacia berlandieri". However those claims concerning Acacia species have been challenged and have been unsupported in additional analysis. Peyote has been used for at least 5,700 years by Native Americans in
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
