I guess after seeing my sister in-law being diagnosed with COPD and my mother-in-law with COPD and Emphysema and now on Oxygen, I could tell you how I feel about smokers as well, but it doesn't matter what I think. :D My biggest problem with it is the people who are too broke to pay house payments, car payments, electric payments etc, and are on food stamps, but still smoke like a freight train. yep, I have a problem with it...
