Methamphetamine
is a powerful stimulant. The street version of the drug is most often
manufactured illegally in underground labs. Methamphetamine is a drug that
strongly activates certain systems in the brain. It is closely related
chemically to amphetamine, but the central nervous system effects of
methamphetamine are greater. Both drugs have some medical uses, primarily in the
treatment of obesity, but their therapeutic use is limited. 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. Methamphetamine is also known as "speed" or "crystal" when it is swallowed or sniffed; as "crank" when it is injected; and as "ice" or "glass" when it is smoked. Ice is clear chunky crystals that resemble ice. All forms of methamphetamine are extremely dangerous and induce long-lasting, debilitating effects. Methamphetamine has a high potential for abuse and dependence. Side effects of methamphetamine use include irritability, nervousness, insomnia, nausea, hot flashes, dryness of the mouth, sweating, palpitations, and hypertension. Excessive doses can produce mental confusion, severe anxiety, and paranoia. Continued moderate to chronic use may lead to physical dependence and even death. Methamphetamine is a Schedule II drug under Federal regulations, meaning it has a high potential for abuse with severe liability to cause dependence.
