hat is AMT?

AMT is a common name for a synthetic drug with the chemical name alpha-methyltryptamine. Abused for the hallucinogenic and stimulative effects it produces, AMT belongs to a class of chemical compounds known as tryptamines. Other hallucinogenic tryptamines include 5-MeO-DIPT (5-methoxy-N, N-diisopropyltryptamine, also known as foxy), psilocybin, and psilocyn.

How is AMT used?

AMT typically is consumed orally in 15- to 40-milligram dosages, although dosage amounts vary widely. The drug also may be administered via snorting or smoking. Users typically begin to feel the drug's effects within 3 to 4 hours after administration. The hallucinogenic and stimulative effects generally subside after 12 to 24 hours but may last up to 2 days.

Who abuses AMT?

AMT typically is abused by teenagers and young adults. The drug is used at raves, nightclubs, and other venues where the use of club drugs, particularly MDMA (3,4-methylenedioxymethamphetamine, also known as ecstasy), is well-established. AMT also is used at private parties.

What are the risks?

AMT produces various negative physical and psychological effects in users. Physical effects include visual and auditory disturbances and distortions, increased blood pressure, blurry vision, dilated pupils, and nausea. Psychological effects associated with the use of AMT include terrifying hallucinations, emotional distress, nervousness, tension, irritability, restlessness, and inability to sleep. AMT also diminishes user inhibitions, which can result in high-risk sexual activity or accidental injury. Overdoses of AMT can lead to death.
