I'll tell you where you can smoke
I have smoked one cigarette in my life--because I wanted to blow smoke rings--but I reserve no ill-will for people who smoke. I reserve all of my ill-will in this regard for people who smoke in the presence of others without regards to their wishes or their health. And, yes, smoking in public places has a negative effect on health, according to a[nother] recent study.
The argument about smoking bans is fairly polarized, but there is some middle ground. My own opinion lies in this middle ground, actually, where I have the right to a large selection of smoke-free public places such as restaurants and bars, and where those inclined to smoke also have a reasonable selection of places where they might be allowed to do so. I firmly believe that people should be allowed to harm themselves given that they accept all risks, and they don't impose on others.
The options for partial smoking bans range from the very lenient mandatory "non-smoking section" to the banning of smoking everywhere except in private establishments such as cigar clubs. I don't know how many countries or U.S. states enacted which versions of bans (I wish I had the statistics) but I know that my home state of Ohio went whole-hog. I think that's stupid.
People have a right to smoke, but they don't have a right to blow it in my face. The city and local governments should be able to issue a fixed number of smoking licenses, in much the same way that liquor licenses are distributed. There would be enough licenses for, say, 10% of restaurants and bars to be able to allow smoking. Maybe there could be more. There must be a fair method of distribution. Mechanisms for alcohol and possibly also carbon emissions might be used as models.
The last hurdle would be smoking opponents who say that workplaces engulfed in smoke are not safe for employees. There must be a solution for this problem, whether it be simple monetary compensation, heavy-duty air filtering, or rotational employment between smoky and fresh-air locations.
Smoke definitely bothers me, to the point where sometimes I believe I have an allergy. But then again, some people like that sort of thing, and I'm not above letting them participate.
