Methamphetamine, a derivative of amphetamine, is a powerful stimulant that affects the central nervous system. Amphetamines were originally intended for use in nasal decongestants and bronchial inhalers and have limited medical applications, which include the treatment of narcolepsy, weight control, and attention deficit disorder. Methamphetamine can be smoked, snorted, orally ingested, and injected.
It is accessible in many different forms and may be identified by color, which ranges from white to yellow to darker colors such as red and brown. Methamphetamine comes in a powder form that resembles granulated crystals and in a rock form known as "ice," which is the smokeable version of methamphetamine that came into use during the 1980s.
