Common questions

Why is ayahuasca active orally when pure DMT is not?+

Ayahuasca combines DMT-containing plant material with a monoamine oxidase inhibitor from another plant, which blocks the enzyme that would otherwise break down DMT in the gut and liver before it reaches the brain.

Does finding trace DMT in a person's blood prove recent drug use?+

Not necessarily at very low levels; DMT occurs endogenously in trace amounts in humans, so toxicologists interpret concentration against reference ranges for endogenous production rather than treating any detectable level as proof of ingestion.
