unless you are licking the walls you are not taking in carcinogens- Carcinogens are airbourne for the most part- once the carcinogens settle on something, it becomes lodged and stuck in a sticky residue-

You will however still have the smell of tobacco- but the smell isn’t toxic-

Just don’t lick the walks and you’ll be fine

The smell may not cause cancer but it stinks on ice. Worse than farts which at least dissipate over time.
