Methamphetamine Information
Methamphetamine is an addictive stimulant drug that is
chemically related to amphetamine, but the central nervous system effects of
methamphetamine are greater.
Methamphetamine is made in illegal
laboratories and has a high potential for abuse and addiction. Street
methamphetamine is referred to by many names, such as "speed," "meth," and
"crank." Methamphetamine hydrochloride, clear chunky crystals resembling ice,
which can be inhaled by smoking, is referred to as "ice" or "crystal."
Methamphetamine is taken orally or intranasally (snorting the powder),
by intravenous injection, and by smoking. The effects of meth on the Central
Nervous System include irritability, insomnia, confusion, tremors, convulsions,
anxiety, paranoia, and aggressiveness. Hyperthermia and convulsions can result
in death.
Methamphetamine causes increased heart rate and blood pressure
and can cause irreversible damage to blood vessels in the brain, producing
strokes. Other effects of methamphetamine include respiratory problems,
irregular heartbeat, and extreme anorexia. Its use can result in cardiovascular
collapse and death.
According to the National Survey on Drug Use and
Health, approximately 12 million Americans age 12 and older had tried
methamphetamine at least once in their lifetimes, with the majority of
past-year users between 18 and 34 years of age. Total current meth users is
estamated to be around 600,000 people. Significant decreases in past year use
were seen among 12- to 17-year-olds.
