I know a few people are saying why not just ban smoking completely, and aside from jnoiles arguement that it's actually a money spinner, consider prohibition in the the US - criminal organisations running the production and distribution of alcohol at inflated prices, with god (who?) knows what kind of impurities, pretty much the same as you get with any illegal drug. Legalise them and let the government control them and not only will the quality improve but it'll bring more income rather than costing the country to police and the associated healthcare costs. But sure, ban smoking if you like, see how long it lasts ...
