Pass it up! I really believe that I can sit there while my friend smokes and that it won't bother me, except it might cause me to cough. I don't like the smell of cigarette smoke. (I've always used clean air machines.) Fortunately, I was one of last of my circle of friends to quit smoking. The vast majority of my friends were, and are nonsmokers. I think I only have one smoking friend, and she lives in Oakland, CA. Now many of my relatives smoke, but they cannot do so indoors at family gatherings.
