We’ve all heard about the negative effects of smoking and passive smoking; most notably, the development of cancer.

Passive smoking has always been considered to be just as bad as actual smoking, which has been a driving force in bringing in smoking bans.

However, it’s been revealed that evidence claiming passive smoking is dangerous is actually inconsistent.

Nearly ten years after Ireland introduced the first workplace smoking ban, the latest report on the lung cancer risks of passive smoking contradict previous research.

Apparently, “exposure to passive smoking overall, and to most individual categories of passive smoking, did not significantly increase lung-cancer risk.”

However, if you live with a smoker, you may be in trouble as the report “shows a trend of increased risk was living in the same house with a smoker for 30 years or more”.
