I'm also a non-smoker who feels that smokers should be able to smoke outside...to a point. If they are in close quarters with others (e.g., outdoor dining patio at a restaurant, crowded concert) they should have enough consideration for others not to light up, knowing that they are not only bothering others with their smoke but poisoning them with it, too. The problem is, many smokers care more about their "right" to smoke than others' NEED for clean air. (Remember the days when people actually asked "Mind if I smoke?" before lighting up?) If they're that hard up for nicotine that they can't make it through a meal or a concert, they should chew, which contains the poison to their own bodies.
