Methamphetamine

Methamphetamine or meth is an addictive stimulant drug that strongly activates certain systems in the brain. It produces a temporary state of increased energy, suppressed appetite, and elevated mood. Pure methamphetamine powder is white, odorless and bitter-tasting. Illicit preparations are off-white or yellowish powders, crystals or chunks. They are sometimes packaged as tablets or capsule. Users commonly swallow methamphetamine powder, sniff it, or inject it intravenously. Street methamphetamine is referred to by many names, such as "speed" or "chalk". Methamphetamine hydrochloride, clear chunky crystals resembling ice, which can be inhaled by smoking, is referred to as "ice", "crystal" and "glass".

The central nervous system (CNS) actions that result from taking even small amounts of methamphetamine include increased wakefulness, increased physical activity, decreased appetite, increased respiration, hyperthermia and euphoria. Other CNS effects include irritability, insomnia, confusion, tremors, convulsions, anxiety, paranoia and aggressiveness. Hyperthermia and convulsions can result in death. Some users experience auditory and visual hallucinations as well as a sensation similar to "coke bugs". They believe insects are crawling under their skin and may pick at their bodies until the skin is raw and bleeding.

Chronic use of methamphetamine is usually marked by rapid weight loss as the body burns itself up. Methamphetamine causes increased heart rate and blood pressure and can cause irreversible damage to blood vessels in the brain, producing strokes. Other effects include respiratory problems, irregular heartbeat, and extreme anorexia. Other physical effects of long-term use may include poor coordination, tremors and blurred vision.
