Metabolite Identification
Common NameDimethyltryptamine
DescriptionDimethyltryptamine is an N-methylated indoleamine derivative, a serotonergic hallucinogen found in several plants, especially Prestonia amazonica (Apocynaceae) and in mammalian brain, blood, and urine. It apparently acts as an agonist at some types of serotonin receptors and an antagonist at others. DMT is a derivative of tryptamine with two additional methyl groups at the amine nitrogen atom. DMT is often synthesized by the Speeter-Anthony synthesis from indole using oxalyl chloride, dimethylamine, and lithium aluminium hydride as reagents. DMT is usually used in its base form, but it is more stable as a salt, e.g. as a fumarate. In contrast to DMT's base, its salts are water-soluble. DMT in solution degrades relatively fast and should be stored protected from air and light in a freezer. Highly pure DMT crystals, when evaporated out of a solvent and depositing upon glass, often produce small but highly defined white crystalline needles which when viewed under intense light will sparkle, and appear colorless under high magnification. In labs, it has been known to be explosive under a certain degree of heat. 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 visual hallucinations, euphoria, even true hallucinations (perceived extensions of reality). A trip sitter is recommended to assist the drug user in staying physically and mentally healthy, and, in the case of smoked DMT, to catch the pipe if the user loses awareness of it. DMT is classified in the United States as a Schedule I drug. There are no drug tests that would show DMT usage. None of the basic NIDA 5 drug tests or any extended drug test will show a result for DMT. Dimethyltryptamine (DMT), also known as N,N-dimethyltryptamine, is a psychedelic tryptamine. It is not to be confused with 5-MeO-DMT and is similar in chemical structure to the neurotransmitter serotonin. DMT is created in small amounts by the human body during normal metabolism by the enzyme tryptamine-N-methyltransferase. Pure DMT at room temperature is a clear or white crystalline solid. DMT was first chemically synthesized in 1931. It also occurs naturally in many species of plants. DMT-containing plants are used in several South American shamanic practices. It is one of the main active constituents of snuffs like yopo and of the drink ayahuasca. Oral ingestion: DMT, which is broken down by the digestive enzyme monoamine oxidase, is practically inactive if taken orally, unless combined with a monoamine oxidase inhibitor (MAOI). The traditional South American ayahuasca, or yage, is a tea mixture containing DMT and a MAOI. There are a number of admixtures to this brew, but most commonly it is simply the leaves of Psychotria viridis (containing DMT), and the vine Banisteriopsis caapi (the source of MAOI). Other DMT containing plants, including Diplopterys cabrerana, are sometimes used in ayahuasca in different areas of South America. Two common sources in the western US are Reed canary grass (Phalaris arundinacea) and Harding grass (Phalaris aquatica). These invasive grasses contain low levels of DMT and other alkaloids. Taken orally with an appropriate MAOI, DMT produces a long lasting (over 3 hour), slow, but deep spiritual experience. MAOIs should be used with extreme caution as they can have lethal complications with some prescription drugs, such as SSRI antidepressants, and some over-the-counter drugs. Smoked: If DMT is smoked, the maximal effects last for a short period of time (5-30 minutes dose dependent). The onset after inhalation is very fast (less than 45 seconds) and maximal effects are reached within about a minute. The Business Man's lunch trip is a common name due to the relatively short duration of vaporized, insufflated, or injected DMT.

Chemical Taxonomy
Description belongs to the class of organic compounds known as tryptamines and derivatives. Tryptamines and derivatives are compounds containing the tryptamine backbone, which is structurally characterized by an indole ring substituted at the 3-position by an ethanamine.
