Joe Rogan talks about DMT

Dimethyltryptamine (DMT), also known as N,N-dimethyltryptamine, is a naturally occurring tryptamine and potent psychedelic drug, found not only in many plants, but also in trace amounts in the human body wherein its natural function is undetermined. Structurally, it is analogous to the neurotransmitter serotonin and other psychedelic tryptamines such as 5-MeO-DMT and 4-HO-DMT. DMT is created in small amounts by the human body during normal metabolism by the enzyme tryptamine-N-methyltransferase.

DMT is a powerful psychoactive substance. If DMT is smoked, injected, or orally ingested with an MAOI, it can produce powerful entheogenic experiences including intense visuals, euphoria, even true hallucinations (perceived extensions of reality).

Many cultures, indigenous and modern, ingest DMT as a psychedelic in extracted or synthesized forms. Pure DMT at room temperature is a clear or white to yellowish-red crystalline solid. DMT was first chemically synthesized in 1931.

DMT occurs naturally in many species of plants often in conjunction with its close chemical relatives 5-MeO-DMT and bufotenin (5-OH-DMT). DMT-containing plants are commonly used in several South American shamanic practices. It is usually one of the main active constituents of the drink ayahuasca, however ayahuasca is sometimes brewed without plants that produce DMT. DMT occurs as the primary active alkaloid in several plants including such plants as Mimosa hostilis, Diplopterys cabrerana, and Psychotria viridis. DMT is found as a minor alkaloid in snuff made from Virola bark resin in which 5-MeO-DMT is the main active alkaloid. DMT is also found as a minor alkaloid in the beans of Anadenanthera peregrina and Anadenanthera colubrina used to make Yopo and Vilca snuff in which bufotenin is the main active alkaloid.

Psilocybin, the active chemical in psilocybin mushrooms can also be considered a close chemical relative for the psilocybin molecule contains a DMT molecule at the end as with other close chemical relatives (4-Phosphoryloxy-N,N-dimethyl-tryptamine).

DMT is generally not active orally unless it is combined with a monoamine oxidase inhibitor (MAOI), such as harmaline. Without a MAOI, the body quickly metabolizes orally-administered DMT, and it therefore has no hallucinogenic effect unless the dose exceeds monoamine oxidase's metabolic capacity (very rare). Other means of ingestion such as smoking or injecting the drug can produce powerful hallucinations and entheogenic activity for a short time (usually less than half an hour), as the DMT reaches the brain before it can be metabolised by the body's natural monoamine oxidase. Taking a MAOI prior to smoking or injecting DMT will greatly prolong and potentiate the effects of DMT.

The psychotropic effects of DMT were first studied scientifically by the Hungarian chemist and psychologist Dr. Stephen Szára who performed research with volunteers in the mid-1950s. Szára, who later worked for the U.S. National Institutes of Health, had turned his attention to DMT after his order for LSD from the Swiss company Sandoz Laboratories was rejected on the grounds that the powerful psychotropic could be dangerous in the hands of a communist country.
