I think that if the tank (or whatever you keep her in) smells like smoke still, I would be putting her into a new environment anyways.

I have heard of snakes getting sick from second hand smoke but I don't have any experience in it myself. If you do take her to a vet my advice would be to find someone who actually looks over snakes. Otherwise you will be charged for a vet visit just to be told to take them to a specialist anyways. Lol or just get poor advice from them.
