I've never really smoked, and definitely not cigarettes, just played some with pipes and cigars. I'll still occasionally have a cigar - with friends on Christmas & New Year's Eve, and a pipe occasionally during a historic reenactment. So I'm not entirely certain what that makes me by the above poll, though I voted tried once/twice. Tobacco use per year - probably less than once a month, and cigarettes never.
On the other hand, I firmly believe we're reacting to the harm from smoking (& second hand smoke especially) excessively. (I'm not arguing that both smoke & second hand smoke don't harm people, just that our reaction is excessive.) I view smoking at least partly as a question of personal freedom - should there be smoke-free locations - absolutely. Should there be venues where smoking is permitted, and if you want to be there you'll have to deal with the smoke - again, absolutely. The question in part is how much should we the people allow government to control our habits/vices. Tobacco's a specially vexacious question because here in the US, we support the growing of tobacco through farm subsidies, we also restrict the growing of tobacco through allotments given historically to farmers, we tax the blazes out of it at state and national levels and use the taxes for various reasons, and we also have the "tobacco settlement" with big pay-outs for lawyers and the states that was supposed to in part provide money for Stop Smoking campaigns and health support for smokers. Jeez - talk about schizoprenic behaviour!
Overall - I guess I take a more libertarian view - people should be able to engage in potentially dangerous behaviour when they know the dangers involved (Not true, I agree in the past, but I'm 52, and find it difficult to believe that anyone my age or younger isn't well aware of the dangers of smoking tobacco.), and also when their actions have minimal affect on others. I'm also not certain if the results of government restrictions on recreational substances are't as negative as the free use of them might be/was. (NB - personally, the only 2 drugs I use on a regular reoccuring basis are caffeine and alcohol, as a glass or 2 of wine with dinner & and an occasional single malt scotch with friends.)
