Methamphetamine is an addictive stimulant drug that strongly activates the central nervous system. It can be smoked, snorted, orally ingested, and injected. It is available in many different forms and may be identified by color, which can range from white to yellow to darker colors such as red and brown. Methamphetamine comes in a powder form that looks like granulated crystals and in a rock form known as “ice,” which is the smokeable version of methamphetamine.
Methamphetamine is commonly known as “speed,” “meth,” and “chalk.” In its smoked form, it is often referred to as “ice,” “crystal,” “crank,” and “glass.” It is a white, odorless, bitter-tasting crystalline powder that easily dissolves in water or alcohol. The drug was developed early last century from its parent drug, amphetamine, and was used originally in nasal decongestants and bronchial inhalers. Like amphetamine, methamphetamine causes increased activity and talkativeness, decreased appetite, and a general sense of well-being.
