“BUT HOW ABOUT OBESITY ITS JUST AS BAD MAYBE WORSE WHY DONT I HEAR ANYBODY POSTING ABOUT THAT????? “
That would probably be, because while obesity is potentially dangerous for the person who is obese, it is NOT a habit and it does not cause physical harm to the rest of the world. When you smoke,you ingest the tar and nicotine, but I have to breathe the air you polluted when you exhaled. When I overeat, I am the only one who will gain 10 lbs. and not you, too.
