Methamphetamine: Overview
Long Description
Chemical & Physical Properties
Methamphetamine (N-methyl-1-phenylpropan-2-amine) has a molecular formula of C₁₀H₁₅N and a molecular weight of 149.23 g/mol. Illicit forms include powder (“speed”), crystalline (“ice” or “crystal”), and liquid. The drug has a half-life of approximately 10-12 hours, with effects lasting 4-12+ hours depending on route of administration.
Mechanism of Action
Methamphetamine acts primarily by causing the massive release of dopamine, norepinephrine, and to a lesser extent, serotonin, while also blocking their reuptake. This results in intense euphoria, increased energy and alertness, suppressed appetite, and elevated heart rate and blood pressure. The profound dopamine surge is responsible for its high addiction potential.
