Article Summary

About AMT

AMT Profile

Alpha-methyltryptamine (AMT) is a stimulant hallucinogen that has recently been emerging in the club and rave scene. It is part of a class of chemicals called tryptamines, which produce hallucinogenic effects.1 AMT and another tryptamine analog, foxy methoxy (5-MeO-DIPT), were placed into Schedule I of the Controlled Substances Act in April 2003.2 The Drug Enforcement Agency considered the threat of abuse and harm high enough to send AMT through emergency scheduling provisions to have its sale made illegal. Because this drug is so new, not much is known about its pharmacological effects.


Although AMT has been in existence for many years, authorities have only recently noted an increase in use. For a short period during the 1960s, AMT was sold as an antidepressant in the Soviet Union.3 It is most often sold in conjunction with foxy methoxy.4

Methods of AMT Use

AMT is most often found in a crystalline powder form with an off-white or orange hue.5 This powder can be portioned into pills or capsules or mixed into water for ingestion. The drug can also be taken intranasally or smoked. A typical dosage of AMT is around 20 to 40 milligrams.6 The drug is most often purchased from chemical companies on the Internet.7

AMT Effects

The effects of AMT, foxy methoxy, and other tryptamines are highly dose-dependent. A moderate dose of AMT (20 mg) causes effects that last anywhere from 12 to 24 hours.8 Some reports contend that the effects of AMT are similar to those of mescaline.9
