What does detoxified mean?
Detoxified is the past tense and past participle of the verb detoxify, meaning to remove poisonous or harmful substances from a person, organism, substance, or environment. It appears in two main contexts: in medicine, where a patient is detoxified during supervised withdrawal from drugs or alcohol, and in science and industry, where water, soil, food, or chemicals are detoxified to make them safe. The word carries a clinical, technical connotation and belongs mostly to formal writing — doctors, researchers, and regulators say things like "the site was detoxified before redevelopment." Its root lies in the Greek toxikon, originally referring to poison smeared on arrows, which also gives us toxin, toxic, and intoxication. In casual conversation English speakers usually prefer the shorter forms detox or detoxed, reserving detoxified for precise, technical description.
verbPast tense and past participle of "detoxify": to remove toxic or poisonous substances from something, such as a person's body, a substance, or an environment; also, to treat a person so as to free them from dependence on drugs or alcohol.

The word "detox" is just a clipped form of "detoxify" — the same root that gave us "toxin" comes from the Greek "toxikon", meaning poison for arrows.

Etymology of detoxified
The word derives from the prefix de- (removal or reversal), attached to toxic, which ultimately traces back to the Greek toxikon pharmakon, meaning "poison for arrows" (from toxon, "bow"). Latin adopted this as toxicum before it entered European languages. Detoxify itself formed in English in the late nineteenth century by combining de- with the adjective toxic; its derivative noun detoxification followed soon after. Cognate family members include toxin, toxicology, intoxication, and cytotoxic.

How detoxified is actually used
"Detoxified" belongs chiefly to formal, scientific, and medical registers. In everyday speech people more often use the clipped noun or verb "detox" (e.g. "she detoxed for a week"). In medical contexts it typically refers to managed withdrawal from drugs or alcohol; in environmental and food-science contexts it refers to removing poisons from a substance or site. It should not be confused with the wellness-industry sense of "detoxing", which often lacks scientific backing.
