..DMT is found naturally in small amounts in human blood, cerebrospinal fluid, and urine, along with NMT, bufotenine and other amines [see:
Determination of potentially hallucinogenic N-dimethylated indoleamines in human urine by HPLC/ESI-MS-MS.
..it's role is not known, but it appears to be required in everyday normal conscious functioning..
the claims that it is released at death, or is in the pineal, are purely speculative..there is no direct evidence (there is evidence of ß-carbolines and 5methoxy-tryptamine in the pineal, and i have been told recently by S. Voogelbreinder, also 5meothyDMT)
..there is no current fast enough methodology to test the released at death theory..
the fact that DMT has no physiological tolerance [Strassman] indicates that it is a readily up-taken, low toxicity substance..
