What Is Methamphetamine?
Methamphetamine is a synthetic central-nervous-system stimulant chemically related to amphetamine, but substantially more potent, longer-acting, and more neurotoxic. It triggers a large release of dopamine, norepinephrine, and serotonin, and it also blocks their reuptake — which is what produces the characteristic long-lasting euphoria, hyper-alertness, and suppressed appetite. The euphoric "high" from methamphetamine commonly lasts 6 to 12 hours, compared to roughly 15 to 30 minutes for snorted cocaine, and it is followed by a severe crash that drives the binge-and-crash pattern clinicians see again and again.
On the illicit market, methamphetamine primarily appears in two forms. Powder methamphetamine is the older form — an off-white or yellowish powder, usually snorted, swallowed, or dissolved and injected. Crystal methamphetamine, known as "ice," "glass," or "shards," is a higher-purity crystalline form that is typically smoked from a glass pipe or injected. Crystal meth is what dominates the supply today. Over the past decade, small-scale U.S. production from pseudoephedrine-based home labs has been almost entirely replaced by high-purity, mass-produced methamphetamine trafficked from large-scale operations across the Mexican border. The result is that street methamphetamine in 2026 is cheaper, purer, and more widely available than at any point in the last thirty years, which is part of why rural communities in Southeast Tennessee have been hit so hard.
Like cocaine use disorder, there is no FDA-approved medication-assisted treatment for methamphetamine use disorder. Despite decades of pharmaceutical research, no medication has been approved by the FDA for stimulant addiction the way medications exist for opioid and alcohol use disorders. Effective treatment for methamphetamine is therefore behavioral: evidence-based counseling, the Matrix Model and similar structured curricula, contingency management, intensive outpatient programming, peer support, and psychiatric medication for the co-occurring mental health conditions that are common in long-term meth users.
That absence of a pill does not mean treatment doesn’t work. It means the mechanism is different. Behavioral treatment for methamphetamine use disorder is well-researched, well-funded, and measurably effective — but it requires showing up to something structured, repeatedly, during the long window of anhedonia and cravings that follows last use.
