I have always wondered this. The company asks if you smoke or not. Lets assume you dont smoke and you get cancer from 2nd hand smoke. How do they proove that. Or vice versa, you do smoke but told them you didnt. You get lung cancer and die. How do they prove you were a smoker and it wasnt from second hand smoke. I guess if the person smoked for a long time, it would be pretty evident they were a smoker. What about for a social smoker though that only smoked lets just say a pack a year?
