drug-abusing

The compound adjective 'drug-abusing' is a modern English formation built from three distinct elements. The noun 'drug' entered English via medieval trade, originally referring to any medicinal substance. The core 'abus' derives from Latin abuti, combining ab- (away, from) and uti (to use), thus literally meaning 'to use away' or 'to use up', which evolved to signify misuse or perversion of purpose. The suffix '-ing' is the native English present participle marker, here converting the verbal action 'to abuse drugs' into an adjective describing a person or behavior characterized by that action. The term's logic is transparent: it literally describes the act of using pharmacological substances in a harmful, improper, or excessive manner, directly linking the object ('drug') with the negative action ('abusing').
