narkōtikos

Greek narke meant numbness or stupor — specifically the numbness caused by the torpedo fish (Torpedo torpedo), a ray that delivers electric shocks strong enough to numb the hand holding a fishing line. Narkōtikos described anything that caused numbness or stupor. The word entered medieval medical Latin as narcoticum, describing drugs that dulled sensation and induced sleep.

Opium was the original narcotic in Western medicine. The Sumerians cultivated poppies and described opium's effects by 3400 BCE. Hippocratic medicine used opium preparations for pain relief and as anesthesia during surgery. Paracelsus, the 16th-century Swiss physician, introduced laudanum — opium dissolved in alcohol — as a tincture that became Europe's most widely used pain remedy for 300 years.

The chemical isolation of morphine from opium by Friedrich Sertürner in 1804, codeine in 1832, and the invention of the hypodermic needle in 1853 transformed narcotics from folk remedies into industrialized pharmaceuticals. Bayer's 1898 launch of heroin (diacetylmorphine) as a 'non-addictive' morphine substitute was one of the more catastrophic pharmaceutical miscalculations in history.

The legal category 'narcotics' now covers substances far beyond the Greek numbness definition — in the United States, narcotics encompasses cocaine and other stimulants that do not cause numbness at all. The legal category has expanded beyond the medical one. The Greek torpedo fish's numb hand is unrecognizable in the Drug Enforcement Administration's schedules.
