I'm a non smoker, and would prefer no smoking in a restaurant. Outside, I don't much care, unless someone is right in top of me. On some other boards I frequent, I would say the hostility is pretty much evenly divided (smokers vs non) and it's turning into a ridiculous argument.

In all honesty, I see nothing coming from this for tourists, except maybe an end to smoking in jamaican restaurants. I think some folks just look for a chance to argue or make outrageous statements on the Internet. Really, for the US and Canadian citizens (thanks for education, Robin) it is really no different than at home...
