What is methamphetamine (meth)?
Methamphetamine—known as “meth”— is a laboratory-made, white, bitter-tasting powder. Sometimes it's made into a white pill or a shiny, white or clear rock called crystal. Meth is made in the United States and often in Mexico—in "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 a common ingredient in cold medicines. Drug stores often put these products behind the counter so people cannot use them to create meth in home labs. Other chemicals, some of them toxic, are also involved in making methamphetamine. Meth is sometimes pressed into little pills that look like Ecstasy to make it more appealing to young people.
Methamphetamine is a 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, and use can lead to addiction. Methamphetamine’s pleasurable effects can disappear even before the drug levels fall in the blood, leading people to use more and more, sometimes not sleeping and using the drug for several days.
Methamphetamine is classified as a Schedule II drug, meaning it has high potential for abuse and is legally available only through a prescription that cannot be refilled. It is prescribed by doctors in limited doses in rare cases for certain medical conditions.
How Methamphetamine Is Used
- injected with a needle
“Crystal meth” is a large, usually clear crystal that is smoked in a glass pipe. Smoking or injecting the drug delivers it very quickly to the brain, where it produces an immediate and intense high. Because the feeling doesn’t last long, users often take the drug repeatedly, in a “binge and crash” pattern.
