You smell like it, you just dont know it. Take it from an EX smoker of YEARS. I can smell a cover-up attempt 20 feet away. And if you smoke in your car, your car HAS to smell also. I NEVER noticed it when I smoked but once i stopped i could smell my car and it was AWFUL! Plus anything that was in my car smelled too ( purse, backpack, clothes)
Once you give it up you will see what I am talking about.
Good luck to everyone trying to stop. It is NOT easy :)
