I quit smoking over 24 years ago - I really don't care for smoking, and I think it STINKS...but I'm not saying that other people cannot smoke if they wish.
nutjobs academics out of Australia are suggesting that smokers be licensed, and have to pay the government for the amount of cigarettes they buy. The whole argument is found here http://www.plosmedicine.org/article/info%3Adoi%2F10.1371%2Fjournal.pmed.1001342
Remember the liberals were all about "get the government out of our bedrooms"? Now they're wanting to regulate pretty much every doggone behavior.
