What It Is:

Methamphetamines are stimulants, a type of drug that gives someone the ability to stay awake and do continuous activity with less need for sleep.

These drugs are produced as pills, powders, or chunky crystals called ice. Ice, nicknamed crystal meth, is a popular drug, especially with young adults and for those who frequently go out to dance clubs and parties.

Sometimes Called: speed, uppers, meth, crystal meth, chalk, ice, glass, Christmas tree, crank (especially when injected)
How It's Used: Methamphetamines are swallowed, inhaled, smoked, or injected into a vein.
What It Does: Swallowed or snorted (also called bumping) methamphetamines give the user an intense high. Injections create a quick but strong intense high, called a rush or a flash.

People who abuse methamphetamines feel high and full of energy. They think the drug will allow their bodies to keep going and going. But methamphetamines are very damaging to the body and brain, especially with repeated use.

Side effects include rapid breathing, an irregular heart rate, and increased blood pressure. Users also complain of sweating, headaches, blurred vision, dry mouth, hot flashes, and dizziness. Since the drug often decreases or even eliminates appetite, it has been used as a dangerous dieting strategy for people trying to lose weight quickly.

Long-term use of methamphetamines can bring on brain damage that causes problems with memory and body movements, and can cause mood swings and violent behavior.

When used in larger doses, methamphetamines can cause dangerously high body temperature, confusion, convulsions (uncontrollable jerking body movements), and even death.
