What does the term 'narcotic' derive from?

The term 'narcotic' is derived from the Greek word "narkōtikos," which translates to "stupor." This origin highlights the primary effect of narcotics, which is to induce a state of numbness or sedation. Historically, substances classified as narcotics have been known to dull the senses and relieve pain, often leading to a state of stupor or unconsciousness when used in sufficient quantities. This etymological background underscores the central characteristic of narcotics in their ability to create sedation and affect consciousness. Understanding this origin helps clarify why the term is used for specific drugs that have these sedative properties.
