AMT is a psychedelic amphetamine-tryptamine first developed in the 1960's for anti-depressant research , although it was never very successful as a prescription antidepressant. Its effects usually last 8-14 hours when swallowed and 3-6 hours when insufflated. Its effects are often characterized as a cross between a psychedelic and an MDMA, with empathogenesis and strong physical stimulation common. One common side effect with both insufflated and oral ingestion of AMT is powerful nausea and associated vomiting.
A standard oral dose of AMT is between 15 - 60 mg.
