"Underlying explanations include declines in the prevalence of smoking and improved nutrition, and a major cause is social policies that target the most disadvantaged."
It will be interesting how history treats smoking in the long term (next century). I am still interested in the solutions proposed (and defeated) in Singapore and Tasmania where persons born after 200x may not purchase cigarettes. I lean libertarian but this is one area I think government is needed. Taking (or taxing) a pleasure away from someone who has enjoyed it for years is not nice, but preventing people from falling into the trap is different.
