Many agents in the class of tryptamines are hallucinogenic substances that exist naturally in some plants, fungi, and animals, but also can be produced synthetically. These hallucinogens have been placed in Schedule I of the CSA (Controlled Substances Act) and include psilocybin, psilocyn, bufotenine, alpha-ethyltryptamine, diethyltryptamine, and dimethyltryptamine. There are also numerous types of tryptamines available, including AMT (alpha-methyltryptamine) and Foxy (5-MeO-DIPT), that are not listed under the CSA.
