she definitely didn’t get their overnight, so I’d say she’s already not there.

In any case, it’s illegal to smoke inside public buildings in most places; at least, in the US. I would be shocked if she wasn’t in violation of that. (Some states allow designated smoking rooms, but that’s a different matter.) And it doesn’t matter if your blowing the smoke “away”… if some one can smell it, they’re breathing second hand smoke.
