The scientists found that lung cancer is not related with passive smoking.


Scientists from Stanford University have found that lung cancer is not directly related with passive smoking. A detailed description of the research has been presented in the study at the June 2013 meeting of the American Society of Clinical Oncology in Chicago and published in Journal of the National Cancer Institute. As exception may be people who for more than 30 years are living in the same household with a smoker. But in this case, they may receive only the propensity to lug cancer disease.

"The fact that passive smoking is increasingly not associated with lung cancer, forced scientists to look for other factors of this disease," said Ange Wang, one of the authors of the project.

In observation was attended more than 76,000 people, and the study lasted for a ten years. During this time, lung cancer developed in 901 of the tested person. In total, the risk of lug cancer disease in smokers is in 13 times higher than in those who have never tried cigarettes, and in those who quit the habit - only in four times higher.

To this conclusion the researchers came more than ones, however, to the results of their research has not been brought a lot of attention. For a long time before that, it was thought that tobacco smoke is equally dangerous for smoker as for people surrounding him.

For tobacco control in many countries was introduced the so-called "anti-smoking law". According to it, was prohibited any advertising of tobacco products and for smoking in unauthorized places the person was subjected to a fine. At this time appeared many signs on the streets which reminds about this smoking ban. Sanctions provided for the anti smoking breach prescribed in the legislation, began to be spread not only to advertisers, but also to sponsors of such projects.

It would seem that anyone could be worse than a smoker who poisons himself and others, so says the social advertising, so claimed doctors, but the results of this experiment casts doubt on these claims.

It is possible that at least some of the allegations which are aimed against tobacco smokers are not based on proven facts, and this experiment clearly demonstrates that not all attacks on smokers have a reasonable basis.
