How far away are employees supposed to stand while smoking outside of a restaurant entrance?

Question Details: I work at a small family-owned restaurant and both of our only cooks are smokers who frequently take breaks to sit outside and smoke. The door to the kitchen the steps where they smoke is only a good 3-8 feet away from the front entrance to our restaurant. Often times the kitchen itself reeks of cigarettes and sometimes if the front door is open for too long, the entrance itself smells as well. I have told my employer that they should stand further away to smoke so it doesn't hurt business or my lungs but he says that they are fine as long as they aren't inside the restaurant. I can't possibly believe that there's no law regarding a required distance from the restaurant's entrance. My research regarding NJ law has led me to no answer.
