What You Need to Know About Drugs: Methamphetamines

The crystal form, nicknamed crystal meth, is a popular drug, especially with young adults and for those who frequently go out to dance clubs and parties. The number of teens who abuse crystal meth is on the rise in the United States.

Methamphetamines, like regular amphetamines, also take away appetite. It is a dangerous strategy sometimes used by people trying to lose weight quickly.

Methamphetamines give someone the ability to stay awake and do continuous activity with less need for sleep. They pump up a person's heart rate, breathing, and blood pressure . They also cause sweating, headaches, blurred vision, dry mouth, hot flashes, and dizziness.

People who are abusing 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. Long-term use of methamphetamines can cause brain damage that causes problems with memory and body movement.

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