Smoked or vaporized DMT experiences often last only 5–15 minutes.

DMT (Dimethyltryptamine) belongs to the tryptamine class because its chemical structure is built around a tryptamine backbone, which is derived from the amino acid tryptophan. Tryptamines are known for interacting strongly with serotonin receptors in the brain, especially the 5-HT2A receptor, which is responsible for the intense psychedelic effects associated with compounds like DMT, psilocybin, and LSD.
