Alpha-methyltryptamine (IT-290 or 3-IT)

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.

Price
Rare, but sometimes sold at events for 5-20$ per dose, available from exotic chemical suppliers for 100-150$ per gram, aproximately the same from underground sources

AMT was placed in Schedule I in the United States on April 4th, 2003 through the emergency scheduling procedure. This makes it illegal to buy, sell, or possess without a license.
