Methamphetamine, commonly called “meth,” is a highly addictive synthetic stimulant. Methamphetamine can come in several forms, including a white, odorless, crystalline powder, crystals (rocks), and pills. Depending on the form, the drug can be used through oral ingestion, smoking, snorting, and injection use.

    Methamphetamine is a Schedule II substance, meaning that it is available through a prescription and has high potential for abuse. The drug is derived from amphetamine, a prescribed stimulant that is used to treat ADHD and narcolepsy. However, methamphetamine is more potent than amphetamine medications because more of the drug is able to reach the brain, thus creating an intense, long-lasting stimulant high.
