2013 (when they constitute about 15 with the population) than they had in 1999 (when every day smoking prevalence was about 30 ). When this consistency may have one thing to do with what in an international context might be characterised as Norwegian affluence, it also indicates that the developing "marginalisation of smokers" among the public (that is what we have studied right here, and which we only uncover minor assistance for) is often a different sort of query than the overrepresentation of smokers in marginal dilemma groups (which we've got not studied here).
