drug-dependent

The compound adjective 'drug-dependent' is a modern formation, combining the noun 'drug' and the adjective 'dependent'. The word 'drug' entered English via Middle French and likely older Dutch terms for 'dry', referring to dried medicinal plants. 'Dependent' stems from the Latin verb dependēre, meaning 'to hang down from', composed of de- (down from) and pendēre (to hang). This literal sense of 'hanging from' something evolved metaphorically into 'being contingent upon' or 'reliant on' a supporting factor. Thus, 'drug-dependent' logically describes a state where an individual's condition 'hangs from' or is contingent upon the continued use of a narcotic substance.
