The presence of DMT in human blood and urine has been conclusively reported in a number of papers (Riceberg and van Vunakis, 1978). For many years, its presence in urine was tied to people with schizophrenia and psychosis (Jacobs and Presti, 2005). There is no question that DMT is naturally produced in the human body. The enzymes necessary to produce DMT from tryptamine and serotonin--N-methyltransferase (NMT) and indolethylamine N-methyltransferase (INMT)--as well as the mRNA necessary to produce the enzymes have been shown to exist in human tissues outside the brain.
