This is correct. Don't link cigarette smoke with other pollutants ! Just for the record (without giving too much information) I have rarely seen anatomically normal pink lungs in 10,000 postmortem examinations carried out over 35 years in UK and Malaysia. Almost everywhere now there is atmospheric pollution affecting lung function to varying degrees. There are of course occupational lung diseases following exposure to fumes, inorganic and organic dusts, coal dust, and ....worst of all ...asbestos. Lung cancer and asbestos exposure are related. Not all lung cancers are due to smoking (and not all smokers get lung cancer).
