@daringfireball look: This is a uniform ban of smoking, which is valid given the intense burden it places on society and the health system-- AND, older generations are grandfathered in so that this will proceed with a strategy of gradualism. Partly because that makes this actually have the potential of working ... and partly because the older generations did not have the benefit of a state that actively combated the smoking threat. "there will simply be a black market?" That's not an argument.
