What does methamphetamine do?

Some illegal drugs slow down your system. But methamphetamine speeds it up. In fact, methamphetamine is often known as "speed" or "crank." It is like adrenaline that is made by your body. Users have increased energy. Some may go days without food or sleep. The drug comes in many forms. Users can inject, smoke, inhale, or eat it. Methamphetamine causes an intense rush that may last from minutes to hours.

What are the risks?

Methamphetamine triggers your brain to release large amounts of the chemical dopamine. This causes feelings of extreme well-being. It may also damage the cells that make dopamine. This can make it harder to feel pleasure over time. Using methamphetamine may also lead to these problems:

• Addiction. This means you develop a strong physical and psychological dependence on the drug. And you may not be able to stop taking it on your own. A potent form of methamphetamine known as "ice" or "crystal meth" is even more addictive.

• Overdose. You may need more and more methamphetamine to feel good. But taking too much can lead to seizures or death. According to the CDC, thousands of people die each year from methamphetamine overdose.

• Exposure to HIV. Using shared needles to inject methamphetamine can spread the virus that cause AIDS and hepatitis.

• Hallucinations. You may hear and see things that aren’t there.

• Paranoia. You may have intense feelings of fear of other people.

• Violent action

• Bleeding in the brain

• Severe dental problems, called meth mouth

• Heart problems, such as heart attacks
