As an ex-smoker I have no idea why you're trying to defend the habit. Smoking isn't something to be proud of or defend. Not having the willpower or desire to quit is something to be embarrassed about. Smokers stink, make the areas and people around them stink, and force the people around them to inhale their smoke to the detriment of their own health if they want to breathe.
