the word "stoned" originates from the old english noun "stān," referring to a piece of rock or hard mineral substance. the addition of the adjectival suffix "-ed" historically created the sense of "made of or resembling stone." the modern, dominant meaning of being under the influence of drugs, particularly cannabis, emerged in mid-20th century american slang. this metaphorical extension likens the heavy, immobile, or insensate state induced by the drug to the inert, unfeeling quality of stone.

Structure: stone (noun) + ed (adjective-forming suffix) "stone" (from old english stān, meaning rock, stone) + "ed" (from old english -ed, -od, a suffix forming adjectives from nouns, indicating possession or likeness).
