Dimethyltryptamine (DMT), also known as N,N-dimethyltryptamine (N,N-DMT), is a serotonergic hallucinogen and investigational drug of the tryptamine family that occurs naturally in many plants and animals.[1][2][3][9] DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.[10]

DMT has a rapid onset, intense effects, and a relatively short duration of action. For those reasons, DMT was known as the "businessman's trip" during the 1960s in the United States, as a user could access the full depth of a psychedelic experience in considerably less time than with other substances such as LSD or psilocybin mushrooms.[11] DMT can be inhaled or injected and its effects depend on the dose, as well as the mode of administration. When inhaled or injected, the effects last about five to fifteen minutes. Effects can last three hours or more when orally ingested along with a monoamine oxidase inhibitor (MAOI), such as the ayahuasca brew of many native Amazonian tribes.[12] DMT induces intense, often indescribable subjective experiences involving vivid visual hallucinations, altered sensory perception, ego dissolution, and encounters with seemingly autonomous entities. DMT is generally considered non-addictive with low dependence and no tolerance buildup, but it may cause acute psychological distress or cardiovascular effects, especially in predisposed individuals.

DMT was first synthesized in 1931. It is a functional analog and structural analog of other psychedelic tryptamines such as O-acetylpsilocin (4-AcO-DMT),[13] psilocybin (4-PO-DMT), psilocin (4-HO-DMT), NB-DMT, O-methylbufotenin (5-MeO-DMT), and bufotenin (5-HO-DMT). Parts of the structure of DMT occur within some important biomolecules like serotonin and melatonin, making them structural analogs of DMT.

DMT exhibits broad and variable binding affinities across numerous receptors, showing its strongest interactions with serotonin receptors, especially 5-HT2A, 5-HT1A, and 5-HT2C, which are believed to mediate its psychedelic effects. Endogenous DMT, a psychedelic compound, is naturally produced in mammals, with evidence showing its synthesis and presence in brain and body tissues, though its exact roles and origins remain debated. DMT is internationally illegal without authorization, with most countries banning its possession and trade, though some allow religious use of ayahuasca, a DMT-containing decoction. Short-acting psychedelics like DMT are considered scalable alternatives to longer-acting drugs like psilocybin for potential clinical use.[14][15] DMT is currently undergoing clinical trials for treatment-resistant depression.[16]
