alpha-Methyltryptamine  is a tryptamine (indole ethylamine) derivative that shares

several similarities with various scheduled tryptamine hallucinogens.

Human subjects using alpha-Methyltryptamine report euphoria, stimulation, visual effects such as blurry vision, bright colors, after

images and amphetamine-like mood elevating eff

ects.

Oral AMT has a slow onset of action of  3-4 h but an extended duration of 12-24 h although some users have reported effects for 2days. Although essentially unknown as a recreational drug until the late 1990s, AMT has slowly appeared in various countries as users seek legal highs and alternate hallucinogens.

AMT is less frequently used than other hallucinogenic tryptamines although it has recently seen a relatively low but stable baseline of use globally.

Pharmacologically, alpha-Methyltryptamine has high affinity for the serotonin (5-HT) transporter,a number of 5-HT receptors, and potentlyinhibits reuptake of monoamines dopamine, 5-HT, and norepinephrine reuptake.

Furthermore,AMT was similar to methamphetamine in its effectiveness to release these monoamines.

alpha-Methyltryptamine is also a monoamine oxidase A inhibitor which conceivably could contribute to its

pharmacological effect. The finding that alpha-Methyltryptamine activates 5-HT

2A/Creceptors likely contributes to its hallucinogenic activity. In animals,alpha-Methyltryptamine produced discriminative stimulus effectssimilar to DOM and MDMA.

Some deaths have been associated with alpha-Methyltryptamine especially in combination with other substances and a number of countries have recently added alpha-Methyltryptamine to their controlled substances list. In summary, despite the general lack of pre clinical or clinical data on alpha-Methyltryptamine, it appears that alpha-Methyltryptamine produces effects and toxicities similar to other tryptamine

derivatives with hallucinogenic and stimulatory properties and therefore should be scheduled

as such.

α-Methyltryptamine (abbreviated as αMT, AMT) is a psychedelic, stimulant, and entactogen drug of the tryptamine class.
