If you want to smoke, smoke at your own risk- do not effect othters. I know numerous people who have serious problems to due second hand smoke. The smoke that non smokers inhale is not filtered!! Another thing being that a lot of restaurants are open-no seperate rooms for smoke. Many bars are not closed off from the diners. I just don't think non smokers should be exposed to cigarette smoke. It is unhealthy and goes into the food, peoples' clothes, and peoples' lungs.
