Mescaline it is specifically exempt from legislation. In Canada, mescaline is classified as a schedule III drug under the Controlled Drugs and Substances Act, whereas peyote is exempt. In Russia mescaline, its derivatives and mescaline-containing plants are banned as narcotic drugs (Schedule I). 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
4,5-Dihydroxy-2,3-pentanedione 4,5-Dihydroxy-2,3-pentanedione 4,5-Dihydroxy-2,3-pentanedione (DPD) is an organic compound that occurs naturally but exists as several related structures. The idealized formula for this species is CHC(O)C(O)CH(OH)CHOH, but it is known to exist as several other forms resulting from cyclization. It is not stable at room temperature as a pure material, which has further complicated its analysis. The ("S")-stereoisomer occurs naturally. It is typically hydrated, i.e., one keto group has added water to give the geminal diol. DPD is produced by degradation of "S"-adenosylhomocysteine by the action of the enzyme "S"-ribosylhomocysteinase. The compound probably does not exist as depicted above, but as an
