I would say move to a different state or write your state representatives and let them know how you feel.
Prolonged exposure to second hand smoke can cause some bad things. One of our family friend's kids has bronchitis because of his parents smoking in the house. Now he has a smokers cough and doesn't even smoke.
I'm a smoker but I don't smoke in my house and I don't smoke in my car. Smoking is banned indoors in MN so I can't smoke at bars or pool halls either. I don't usually go out to smoke during a match. You should have to smoke between matches.
I'm really getting sick of these righteous people that don't smoke. Smoking is legal. It probably shouldn't be, but until it's illegal I have the right to smoke outside. Get over it and stop whining.
Also I shouldn't have to pay for your roads or kids hospital bill with my smoking habit. I'm OK with paying for cancer or heart disease research and treatment with the tobacco tax but it shouldn't be used for other things.
I don't think the question here is whether a smoker has the right to smoke. You are right, in that if a person chooses to take up the habit of smoking, that's his/her right to do so. The legal/moral questions are not part of this thread.
Rather, it's the question of, should the smoker be able to do so *during* a match -- a rather rude and inconsiderate thing to do given the information you presented above -- instead of taking his/her smoke break in-between matches?
IMHO, tournaments like the Joss Tour have it right -- it's a hard and fast, black and white, easily-enforced rule with no gray areas: NO SMOKE BREAKS AT ALL when a match is underway. Between matches, yes, go outside and puff away. But once the match is underway, you need to be table-side, or else forfeit.
