Did You Know?
For those who think that alcohol and drugs qualify as poisons, the history of "intoxicate" offers some etymological evidence to bolster your argument. “Intoxicate” traces back to “toxicum,” the Latin word for “poison” -- and the earliest meaning of "intoxicate" was just that: "to poison." This sense is now extremely rare, and we currently talk about such harmless things as flowers and perfume having the power to intoxicate. "Toxicum" turns up in the etymologies of a number of other English words including "toxic" ("poisonous"), "intoxicant" ("something that intoxicates") and "detoxify" ("to remove a poison from"), as well as a number of the names for various poisons themselves.
