Here's an artile from of Wikipedia:
N , N -Dimethyltryptamine
or N , N -DMT
) is anaturally occurringpsychedeliccompound of thetryptaminefamily. Its presence is widespread throughout theplant kingdom.   DMT occurs in trace amounts in mammals, including humans, where it putatively functions as atrace amineneurotransmitter.  It is originally derived from theessential amino acidtryptophanand ultimately produced by the enzymeINMTduring normalmetabolism.  The significance of its widespread natural presence remains undetermined.Structurally, DMT is analogous to theneurotransmitterserotonin(5-HT), thehormonemelatonin, and otherpsychedelictryptamines, such as5-MeO-DMT,bufotenin, andpsilocin(the active metabolite ofpsilocybin).
When ingested, DMT acts as apsychedelic drug.  Depending on the dose and method of administration, its subjective effects can range from short-lived milderpsychedelic statesto powerful immersive experiences; these are often described as a total loss of connection to conventional reality with the encounter ofineffablespiritual/alien realms.
 Indigenous Amazonian Amerindian cultures consume DMT as the primary psychoactive inayahuasca, a shamanisticbrewused for divinatory and healing purposes
. Pharmacologically, ayahuasca combines DMT with anMAOI, an enzyme inhibitor that allows DMT to be orally active.
