Smoking is such a gross selfish habit. I've started using the entrance on the other side of AA just to avoid walking into the smoke cloud. I quit almost 8 years ago and it was such an awesome decision (I used Chantix). I can't stand to see people just flick a butt on the ground or out of a car window. Also the smokers in AA that will smoke half a cigarette and put the other back in their pack. The smell is awful.
