The observation that tolerance to LSD does not confer cross tolerance to several of DMT's autonomic effects suggests that these N-disubstituted compounds may differ in some respects from LSD. The duration of action of DMT is less than that of LSD. Further, we have not been able to demonstrate tachyphylaxis to the actions of tryptamine in the dog (MARTIN and EADES, 1972). Tryptamine's duration of action is less than that of DMT. It is possible that a long duration of action is a necessary attribute of LSD-like hallucinogens for them to effectively induce tolerance (see Subsect. E.III).
Lengthening of the side chain of DMT by a single methylene group produces N,N-dimethylhomotryptamine (DMHT; 76, R = H, n = 3). which produced hyperthermia when administered to rabbits (7,232) but was found to be inactive in man (235). Intravenous administration of 5 and 10 mg and intramuscular injection of 20 to 70 mg DMHT was without psychologic effect in 10 human subjects (235). Additional studies on DMHT homologs (i.e., 76, n = 4–10) did not show any interesting activity (7,232).
[...] all are apparently orally active except for DMT itself, which is orally inactive in doses exceeding 1,000 mg.

After the elaboration of sufficiently selective and quantitative procedures, which are discussed elsewhere, we were able to study the occurrence of tryptamine, N,N-dimethyltryptamine, N,N-dimethyl-5-hydroxytryptamine and 5-hydroxytryptamine in normal human blood and urine. [...] In 11 of 37 probands N,N-dimethyltryptamine was demonstrated in blood (...). In the urine 42.95 ± 8.6 μg of dimethyltryptamine/24 h were excreted.

"When you look at molecules like psilocybin, lysergic acid diethylamide (LSD) or dimethyltryptamine (DMT), they are all almost identical to approved headache medications in terms of their chemical structure and pharmacological profile," Schindler states.

Son of central district judge arrested for allegedly importing DMT – LSD like drug – from Holland. [...] The suspect denies the allegations against him and claims he did not know the substance was on the list of illegal drugs.
