This topic was an old one, but to get short of it, why not just stop smoking if someone is near you specially if there are women and children, this is not just to respect or abide to the Law, but to give respect to the rights of women and kids and to any people not smoking.

 Maybe some doesn't know that the non-smokers will get cancer or other illness easilly than that smoking when inhaled the cigarette? Hope people smoking should consider the other people from taking their habit.
