N,N-Dimethyltryptamine

N,N-Dimethyltryptamine (DMT or N,N-DMT) is a substituted tryptamine that occurs in many plants and animals, including humans, and which is both a derivative and a structural analog of tryptamine. DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen. 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. DMT can be inhaled, ingested, or injected and its effects depend on the dose, as well as the mode of administration. When inhaled or injected, the effects last a short period of time: about five to 15 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. DMT can produce vivid "projections" of mystical experiences involving euphoria and dynamic pseudohallucinations of geometric forms. DMT is a functional analog and structural analog of other psychedelic tryptamines such as O-acetylpsilocin (4-AcO-DMT), psilocybin (4-PO-DMT), psilocin (4-HO-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 is produced in many species of plants often in conjunction with its close chemical relatives 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and bufotenin (5-OH-DMT). DMT-containing plants are commonly used in indigenous Amazonian shamanic practices. It is usually one of the main active constituents of the drink ayahuasca; however, ayahuasca is sometimes brewed with plants that do not produce DMT. It occurs as the primary psychoactive alkaloid in several plants including Mimosa tenuiflora, Diplopterys cabrerana, and Psychotria viridis.

Psychedelic drug

Psychedelics are a subclass of hallucinogenic drugs whose primary effect is to trigger non-ordinary mental states (known as psychedelic experiences or psychedelic "trips") and/or an apparent expansion of consciousness. Sometimes, they are called classic hallucinogens, serotonergic hallucinogens, or serotonergic psychedelics, and the term psychedelic is sometimes used more broadly to include various types of hallucinogens or those which are atypical or adjacent to psychedelia such as salvia and MDMA, respectively; this article uses the narrower definition of psychedelics.
