Psychoactive doses (0.7 mg/kg) of the hallucinogen N,N-dimethyltryptamine (DMT) were administered intramuscularly to 11 normal subjects. A gas chromatographic-mass spectrometric isotope dilution determination of DMT concentrations in whole blood and urine revealed that only a fraction of the injected dose was recovered and the blood DMT concentrations had a very similar time course o the subjectively reported “high”. 

Factors affecting the urinary excretion of endogenously formed dimethyltryptamine in normal human subjects

TLDR
The hallucinogenic substance N′,N′-dimethyltryptamine and its precursor N-methylryptamine were found in 24-h speciments of urine from 19 normal human subjects and the urinary excretion of both compounds was unrelated to age, sex, urinary volume, or creatinine, nor was any consistent diurnal pattern observed.

Neuropharmacology of N,N-dimethyltryptamine

TLDR
This paper reviews the current literature of both the recreational use of DMT and its potential roles as an endogenous neurotransmitter and Pharmacokinetics.

Metabolism and disposition of N,N-dimethyltryptamine and harmala alkaloids after oral administration of ayahuasca.

TLDR
The present results show the existence in humans of alternative metabolic routes for DMT other than biotransformation by MAO and that O-demethylation plus conjugation is an important but probably not the only metabolic route for the harmala alkaloids in humans.

Dimethyltryptamine: Endogenous Role and Therapeutic Potential

TLDR
While the role of endogenous DMT remains unclear, ayahuasca has promising results in anxiety, depression and substance dependence, and it is crucial to conduct further research aimed at developing new treatments for psychiatric disorders.

Dark Classics in Chemical Neuroscience: N, N-Dimethyltryptamine (DMT).

TLDR
The synthesis of DMT is covered, as well as its pharmacology, metabolism, adverse effects, and potential use in medicine.

TLDR
The toxicokinetics and toxicodynamics of the psychoactive DMT and harmala alkaloids harmine, harmaline and tetrahydroharmine, are comprehensively covered, particularly emphasizing the psychological, physiological, and toxic effects deriving from their concomitant intake.

A Methodology for Studying Various Interpretations of the N,N-dimethyltryptamine-Induced Alternate Reality

N,N-dimethyltryptamine, or DMT, is an endogenous psychoactive chemical that has been shown through repeated human subject experimentation to provide the subject with a perception of an ‘alternate

TLDR
DMT produced markedly significant mental effects including anxiety, hallucinations, and perceptual distortions and autonomic changes consisting of pupillary dilatation, increase in systolic and diastolic blood pressure, and a decrease in the kneejerk threshold.

Indole(ethyl)amine N-methyltransferase in human brain.

TLDR
Preliminary evidence gathered in laboratories from rats infused intraventricularly with bufotenin has suggested that this substance is at least as potent as its powerfully hallucinogenic 5-methoxy congener, and may not easily cross the blood-brain barrier.

Tryptamine, N,N-Dimethyltryptamine, N,N-Dimethyl-5-hydroxytryptamine and 5-Methoxytryptamine in Human Blood and Urine

TLDR
5-Methoxytryptamine has been found in the urine of patients with rheumatic fever, and that in an order of magnitude of 30–210 µg/24 h, while N,N-dimethyl-5-hydroxytryptamine was still not demonstrated in blood.

Detection of Psychotomimetic N,N-Dimethylated Indoleamines in the Urine of Four Schizophrenic Patients

TLDR
On the basis of their previous work indicating that tryptamine appeared in increased concentrations in the urine before and during the activation of psychotic symptoms, they suggested that under loading conditions the formation of various N,N-dimethylated indoleamines might be facilitated in the body.

A dimethyltryptamine-forming enzyme in human blood.

TLDR
An enzyme capable of forming the hallucinogen dimethyltryptamine was found in human red blood cells, plasma, and platelets and was higher in psychotic subjects than in nonpsychotics and was apparently related to the presence of a dialyzable inhibitor in the normal subjects.
