In defense of smokers, it is an addiction, not easily given up. My husband was a smoker for many years, and 14 years after he quit smoking he died of lung cancer. I will not be critical of smokers because it is not as easy as just deciding one morning that you will not smoke any more. I have severe allergies to cigarette smoke, but that is not the smokers problem. I also can't be around perfume and a lot of the air fresheners. But also, I have 2 large dogs and know that sometimes my house smells "doggie". I hope I am not judged because I choose to have a four-legged companion. Please have some compassion for those of us who are not "perfect".
