Cigarette smoking is connected with the onset of lung cancer.
It takes 25 years to develop lung cancer. This is the direct outcome of women taking up smoking. I'm so worried about cigarette companies in the West bringing their advertising campaigns to the Middle East, now that they are restrained from advertising in America. This is an important health care problem. The life expectancy of a smoker is 8 years less than that of a non-smoker.
