Your body makes it. DMT is produced endogenously in the mammalian brain. The enzyme INMT converts tryptamine into DMT in the lungs, brain, liver, and blood.

Plants make it too. Found in Psychotria viridis, Mimosa hostilis, Acacia species, and dozens more. It's the active ingredient in ayahuasca, one of humanity's oldest ceremonial brews.

It acts on sigma-1 receptors. Beyond serotonin, DMT binds to sigma-1 receptors — involved in cellular stress response, neuroprotection, and neuroplasticity. This might explain its therapeutic potential.
💡
The pineal gland mystery. Rick Strassman's hypothesis that the pineal produces DMT at birth and death remains unproven but tantalizing. What we do know: rat pineal glands produce DMT. The human question is still open.

MAO breaks it down instantly. Monoamine oxidase in your gut destroys DMT on contact. That's why ayahuasca combines it with MAO inhibitors. When smoked, it bypasses the gut entirely.

5,000+ years of human use. Archaeological evidence from the Sora River valley in Bolivia shows snuff-tray kits containing DMT residues dating to 1000 BCE. This isn't new.

Clinical research is accelerating. Imperial College London, Johns Hopkins, and others are studying DMT for treatment-resistant depression. Extended-state DMT (DMTx) trials are underway.
