The English word "drug" covers a wide range of substances, from illegal narcotics to life-saving medicines. Japanese distinguishes these carefully, and the right word depends heavily on context.

Specifically narcotics or illegal drugs. Strongly associated with crime and addiction.

Stimulant drugs, especially methamphetamine. Very specific term used in legal and news reports.
