What does narco- mean? Narco- is a combining form used like a prefix referring to narcosis. In some instances, narco- is used to refer to various aspects of the trade of illegal drugs trade, i.e., narcotics. Narcosis is a state of stupor or drowsiness, especially as induced by narcotics. Narcotics include drugs such as opiates, heroin, marijuana, and alcohol. Narco- is often used in medical and scientific terms, including in pathology and psychiatry, and often refers to narcotic drugs. Narco- comes from the Greek nárkē, meaning “numbness, stiffness.”Note that narco and narc are slang for a government agent or detective charged with the enforcement of laws restricting the use of narcotics. Both narco and narc are shortened from narcotic, which as you may have guessed, also comes from the Greek nárkē. Narc is sometimes spelled as nark and, while the two terms somewhat overlap in slang sense, nark as slang for “informer” comes from a completely different origin than narcotic.
