No I don't. I'm an ex-smoker and this would be taking things too far. Especially when you consider the amount of pollutants that are given off by vehicles, industry etc. If the governments of the world stop them belching out dangerous crap into the atmosphere then by all means introduce some further restrictions on smoking. I'm all for making the environment safer for everyone, including smokers, but sometimes it feels like there is a bit of a witch hunt going on, not to mention paranoia.
