What does coked mean?
Coked is the past tense and past participle of the verb 'to coke', which has two distinct meanings separated sharply by register. In its primary technical sense, used throughout the coal, steel, and metallurgical industries, it describes coal that has been heated in airless ovens to drive off volatile impurities, leaving behind coke — a porous, high-carbon fuel essential to smelting iron and steel. Sentences like 'the plant coked thousands of tonnes of coal' are standard in industrial writing. Separately, in informal American slang, 'coked' can describe someone under the influence of cocaine, a usage that is colloquial and often inappropriate in polite or formal settings. The two senses rarely collide because their contexts — furnace rooms versus casual conversation — almost never overlap. The word derives from 'coke', the fuel itself, a term of obscure but long-established origin in British English dating back several centuries.
Converted (coal) into coke by heating in the absence of air.
"The plant coked more than a million tonnes of coal last year."
(Informal) Under the influence of cocaine.
"He was clearly coked when he made that reckless decision."
Slang register; avoid in formal or professional writing.
The same three-letter root gives us both a fuel that helped build the Industrial Revolution and one of modern slang's most notorious drug references — context decides which 'coked' you mean.

Etymology of coked
The verb 'to coke' derives from the noun 'coke', the solid carbon fuel produced by heating coal without air. The noun first appears in English in the seventeenth century, with its etymological roots uncertain but generally linked to northern English dialect words for charcoal or the core of burned material. From this noun, the verb developed to describe the process of producing coke from coal, yielding the past form 'coked'. The slang sense relating to cocaine arose much later in twentieth-century American English, derived from 'cocaine' via the clipped form 'coke'; it is etymologically unrelated to the coal-based verb despite sharing its spelling.
