Methamphetamine—known as “meth”—is a very addictive stimulant drug. Stimulants are a class of drugs that can boost mood, increase feelings of well-being, increase energy, and make you more alert—but they also have dangerous effects like raising heart rate and blood pressure.
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. But it is also made in small labs using cheap, over-the-counter ingredients such as pseudoephedrine, which is common in cold medicines. Other chemicals, some of them toxic, are also involved in making methamphetamine.
Methamphetamine is classified as a Schedule II drug, meaning it has high potential for abuse and is available only through a prescription that cannot be refilled. It is prescribed by a doctor in rare cases to treat attention deficit hyperactivity disorder and other conditions. In these cases, the dose is much lower than what is typically used for the purpose of getting high.
