What does the word intoxifaction mean?

"Intoxifaction" is not a commonly used or recognized word in English. It's likely a misspelling of "intoxication," which refers to the state of being affected by alcohol or drugs.

If you encountered "intoxifaction" in a specific context, it's possible that it's a made-up word or a specific technical term. If you can provide more context, I might be able to offer a more accurate interpretation.
