What Is Methamphetamine (Meth)?

Methamphetamine

Methamphetamine—meth for short—is a stimulant drug that is chemically similar to amphetamines. Stimulants are a class of drugs that can boost mood, increase feelings of well-being, and increase energy and alertness—but they also have dangerous effects like raising heart rate and blood pressure.

Meth is a white, bitter powder and easily dissolves in water or alcohol. Sometimes it's made into a white pill or a shiny, white or clear rock called a crystal. Although most of the meth used in the United States comes from “superlabs”—big illegal laboratories that make meth in large quantities—it is also made in small laboratories using inexpensive, over-the-counter and often toxic ingredients like drain cleaner, battery acid, and antifreeze.
