No, this emanates from British researchers (full pdf here), is bang up to date, and derives data from the British Household Panel Survey ... so will therefore be dutifully ignored by Nanny Beeb.
We use three waves of the British Household Panel Survey to examine whether changes in smoking behaviour are correlated with life satisfaction and whether the recent ban on smoking in public places in England, Wales and Northern Ireland has affected this relationship. We find that smokers who reduced their daily consumption of cigarettes after the ban report significantly lower levels of life satisfaction compared to those who did not change their smoking habits, with heavy smokers particularly affected. No such finding is reported for previous years.So then Cameron, if you are true to your word in wishing to enact policy on the back of a measure of happiness, amending the smoking ban is a no brainer, yes?
Or were you just talking bollocks like your mate Nick?
