Methamphetamine is the formal, clinical name for this drug. In everyday conversation — in news reports, TV shows, and casual talk — people almost always shorten it to meth or say crystal meth. Slang terms like ice, crank, and speed are also common but sound very informal or dated. Only use the full word methamphetamine in medical writing, formal journalism, court documents, or academic contexts.
