What a great idea! I have always wanted a government to control my life, and when they do look after my health, perhaps I will live forever. And let's not just stop at cigarettes, think of the harm that comes from all that sugar! So let's ban sweets and chocolates and ice-cream. And how about obesity? Time for the government to step in and ban KFC and McDonalds! All fat people should be put in special camps to "learn" their errors and to recant and eat green stuff. Yeah, all that would sort the country. Great idea!
I'm not advocating for the fun police, and slippery slopes are all well and good, but currently we do ban a hell of a lot of stuff which is less addictive and less harmful than tobacco. While we're taking things to extremes, maybe we should un-ban everything, and let the tobacco or other drug companies market everything from dope to heroin or meth to whoever wants it, just make sure we tax it enough to cover any adverse health effects so the users are paying for the down sides of their fun.
An alternative, raise the smoking age year on year to 'grandparent' in the current legal smokers. The legal age to buy smokes is 18 right now, make it 19 next year, 20 the year after, and so on until the last smoker has given up (one way or the other). That way anyone who currently enjoys the habit is free to continue to their heart's content, but the rate of new smokers will decline.
