Narcotic

The term narcotic, derived from the Greek word narkoticos, meaning "benumbing or deadening", originally referred to a variety of substances that induced sleep (such state is narcosis). In the U.S. legal context, narcotic refers to opium, opium derivatives, and their semisynthetic or totally synthetic substitutes. Cocaine and coca leaves, which are classified as "narcotics" in the U.S. Controlled Substances Act (CSA), are technically not narcotics.

Administration

Narcotics can be administered in a variety of ways. Some are taken orally, transdermally (skin patches) or injected. They are also available in suppositories. As recreational drugs, they are often smoked, sniffed or self-administered by the more direct routes of subcutaneous ("skin popping") and intravenous ("mainlining") injection.
