N,N-Dimethyltryptamine (DMT or N,N-DMT) is a chemical substance that occurs in many plants and animals and which is both a derivative and a structural analog of tryptamine. It is used as a recreational psychedelic drug and prepared by various cultures for ritual purposes as an entheogen (a psychoactive substance that induces alterations in perception, mood, consciousness, cognition, or behavior for the purposes of engendering spiritual development or otherwise in sacred contexts).
DMT is a functional analog and structural analog of other psychedelic tryptamines such as O-acetylpsilocin (4-AcO-DMT), 5-MeO-DMT, psilocybin (4-PO-DMT), psilocin (4-HO-DMT), and bufotenin (5-HO-DMT).
DMT is classified in the United States as a Schedule I drug under the Controlled Substances Act of 1970.
