Mescaline the skills necessary to handle them safely. Special regulations restricting their availability, possession, storage or use may apply."

In Canada, France, The Netherlands and Germany, mescaline in raw form and dried mescaline-containing cacti are considered an illegal drug. However, anyone may grow and use peyote, or "Lophophora williamsii", as well as "Echinopsis pachanoi" and "Echinopsis peruviana" without restriction, as
O-Acetylpsilocin Franz Troxler. Despite this, psilocetin remains a psychedelic compound with a limited history of use. It is theorized to be a prodrug for psilocin, as is psilocybin, which occurs naturally in most species of hallucinogenic mushrooms. This is because the aromatic acetyl moiety on the 4th position is subject to deacetylation by acidic conditions such as those found in the stomach. Psilocetin is "O"-acetylated psilocin, whereas psilocybin is "O"-phosphorylated. "O"-Acetylpsilocin can be obtained by acetylation of psilocin under alkaline or strongly acidic conditions. It is, therefore, a semi-synthetic compound. It is believed to be a prodrug of psilocin, however, speculation
