It's bad but I really just don't give a stuff if people do it or not. It's their life, if they like nicotine, great, if not, fine. I hate the people that try to get laws passed that ban smoking and whatnot. This is 'Murrica. It's supposed to be the land of the free. So don't forget up everything the revolutionaries fought for by trying to make other people live how you want them to.

Also I don't smoke nor will I, and I am in no way better than anyone that does smoke.
Edit: While I'm at it, why the hell do the government officials keep making laws to try to stop crime (i.e. some firearm regulation laws). CRIMINALS DON'T FOLLOW THE DAMN LAW. If they really want to be effective than alter the punishment for breaking the law.
