Ewww...that is so so nasty. I hate people who smoke as well. It grosses me out to no end! I always think of this when ever I see someone smoke:
If you smoked, would you still want to smoke if it effected the outside of your body? Think about it. If it effects the inside of you what happens? Your insides turn all yucky colored black and whatever else. But on the outside? You'd look super nasty. All with black all over your skin. Also, when you smoke, it causes really bad wrinkles on your skin and everywhere!
I know this because I did a pamphlet about this last year...it was sooo nasty!!
