Sources: DEA — Peyote and mescaline

Dosage context

Mescaline and cactus identity

Mescaline is a chemical compound. Peyote is a cactus, and other mescaline-containing cacti have different biological identities. Botanical material also contains components beyond an isolated mescaline preparation.

Sources: DEA — Peyote and mescaline

Psychedelic effects

Mescaline has serotonergic hallucinogenic effects. Perception, emotion and coordination can change, while nausea and other physical effects may occur. A plant’s name does not establish the amount of mescaline in its material.

Sources: DEA — Peyote and mescaline

Religious context and legal scope

Certain religious uses are subject to specific rules and protections. These are not general permission for every person, product or transaction. A statement about one activity cannot establish the status of unrelated retail supply.

Mescaline versus psilocybin and LSD

Mescaline is a phenethylamine; psilocybin is a tryptamine and LSD is a lysergamide. Similar descriptions of psychedelic experience do not make the structures, pharmacokinetics or legal details interchangeable.
