The report, written by the WHO, says there is no link between child hood exposure to and only a slightly higher chance, 25% more likely for adults who work with a smoke or have a spouse as a smoker, however, they way the calculate it is a total farce, 1:80,000 of people exposed to second hand smoke die from lung cancer, where as 1:100,000 who are not exposed to it die from lung cancer. This is just slightly higher then statistically insignificant.
I hate smoke, it smells horrible, and however, there is no scientific evidence to show a conclusive link between second hand smoking and cancer.
