Meth

Methamphetamine—known as “meth”—is a very addictive stimulant drug. 

Also known as:  “Speed”  “Chalk”  “Tina"  “Ice”  “Crank”  “Glass” and “Fire”

Methamphetamine is a manmade, white, bitter-tasting powder. Sometimes it's made into a white pill or a shiny, white or clear rock called a crystal. Most of the meth used in the United States comes from “superlabs”—big illegal laboratories that make the drug in large quantities.

Regular use of methamphetamine causes chemical and molecular changes in the brain. The activity of the dopamine system changes, causing problems with movement and thinking. Some of these changes remain long after methamphetamine use has stopped. Although, some may reverse after a person is off the drug for a long period of time, perhaps more than a year, methamphetamine may destroy nerve cells that produce dopamine and another neurotransmitter called serotonin.


Methamphetamine use can quickly lead to addiction.

That’s when a person seeks out the drug over and over, even after they want to stop and even after it has caused damage to their health and other parts of their life.

Methamphetamine causes tolerance—

when a person needs to take more of it to get the same high. People who usually eat or snort meth might start to smoke or inject it to get a stronger, quicker high.
