α-methyl-tryptamine, also known as α-MT, AMT or IT-290, is a synthetic drug of the tryptamine family. First developed as an antidepressant, in the 1960s it was produced commercially for this purpose in the Soviet Union under the trade name "Indopan" in 5mg and 10mg pills. Like many other tryptamines, at sufficient dosages it is a psychedelic hallucinogen. Its effects may take 2-3 hours to onset, and can last for 18 to 24 hours. It also acts as a monoamine oxidase inhibitor and a stimulant, the latter property possibly being related to similarities in chemical structure to amphetamine. On 4 April 2003, an emergency United States DEA order resulted in α-MT being placed, along with 5-MeO-DIPT, on Schedule I of the Controlled Substances Act.
Effects
AMT is a long-acting psychedelic/euphoric stimulant. It is known to cause nausea and vomiting in many recreational users.
