To make someone drunk or affected by a substance; or to fill someone with such strong excitement or pleasure that they act differently.
From Latin *intoxicare* “to poison,” from *in-* “in” and *toxicum* “poison.” It originally meant poisoning with drugs or alcohol before expanding to emotional or mental “intoxication.”
We usually think of intoxication as alcohol, but ideas, power, and love can all intoxicate the brain. The scary part is that feeling good and being in control are not the same thing at all.
