Someone said cigarettes must be banned because smoking kills people.. Well, so do guns and alcohol.. AND CARS! It's scary how people have nothing better to do but judge people 24/7 while trying to make them more like them or if that doesn't work - remove them from society. I've quit smoking years ago and I have no problem with people smoking.
About the lung cancer - the truth is that no doctor can tell whether it is caused by smoking or not. High percentage of lung cancer victims are non-smokers. In some years the percentage is higher than that of smokers. It's not about second hand smoking.. Whatever the cigarette smoke has can also be found on every highway or large busy street - minus the nicotine (which is not harmful to humans.. Actually it's pretty close to caffeine - and that we all enjoy). So, just because you don't like the sight of a smoking person that doesn't mean he or she must be punished for it. Whiners.
