Simple fact is that since I quit almost 7 yrs ago I can't stand the smell of it around me. I won't ride in a car with a smoker as it burns my eyes up, clothes stink, and the smell of the ash tray would soon be mixed with the smell of my puke. That some people think they are better off smoking is no business of mine. I just choose not to be around them especially diving. So far all the dive boats I've been on do not allow it anyway. I never though I would be so sensitive to it but I can smell someone smoking in the car infront of me if it's warm and the windows are down. In which case mine go up as I don't want that smell in my car. As far as those who don't care about others and light up whenever and wherever that's fine. Just hope I have not had beans the night before.
