Diabetes type 2 risk grows with 'passive' smoking

Lancet journal's meta-analysis says chance of diabetes for non-smokers inhaling 'secondhand' smoke raised by 22%

Non-smokers who breathe in other people's cigarette smoke are at significantly higher risk of developing type 2 diabetes, research published on Friday shows.

"Passive smoking" increases a non-smoker's chances of becoming a diabetic by 22% compared with the chances for those who have never inhaled tobacco smoke, the study says.
