narcotics
This term carries a heavy legal and clinical weight, typically appearing in official police reports, court documents, or medical texts. While it refers to sleep-inducing or pain-relieving drugs, in modern common usage, it is almost exclusively associated with illegal drug trafficking and the criminal justice system rather than general pharmacology.
When referring to the police division, the word functions as a collective noun for the unit. In this context, it is often used without an article (e.g., "working for narcotics") to denote the specific field of law enforcement.
Meanings
Drugs that produce sleep or stupor, specifically those that relieve pain and are often controlled by law due to their addictive nature.
A specialized police or government division responsible for the investigation and prevention of the illegal trade of controlled substances.
Examples
He spent ten years working undercover for narcotics.
