Alpha-methyltryptamine (aMT/AMT) is a long acting synthetic hallucinogen with stimulant properties. It usually comes as an off white or yellowish/orange powder which can be either clumpy or fine. It is also found in tablet form.
AMT is often consumed orally, either by swallowing tablets, wrapping powder in a cigarette paper (bombing) or by taking a small bit of powder from the tip of a moistened finger (dabbing). The powder can be smoked, leading to a faster onset of effects.
