Quitting smoking makes you happier, says study
PARIS (AFP) - Moderate or heavy smokers who quit tobacco get a boost in mental wellbeing that, for people who are anxious or stressed, is equivalent to taking anti-depressants, a study said Thursday.
British researchers examined 26 published investigations into the mental health of smokers.
They looked at standardised scorecards for symptoms of anxiety, depression, stress and quality of life, derived from questionnaires completed by volunteers.
The smokers were 44 years old on average and smoked between 10 and 40 cigarettes a day. They were questioned before they tried to give up smoking and again after their attempt - an average of six months later.
