DMT is extremely powerful and short-lived when taken via smoking or injection. It is interesting because it is an endogenous substance, and it is essentially the root of all of the related hallucinogens like Psilocybin or LSD - . Psilocybin is turned into psilocin, which is 4-hydroxy-N,N-DMT, and then DMT in your body shortly after you ingest it. Compare the chemical structure to LSD, too.
