Harm of Smoking

Smoking is very dangerous according to a review of epidemiological data by the WHO cancer agency. This International Agency published the first evidence for Research on Cancer and linked conclusively smoking with increased risk of cancer. Twenty nine scientists from twelve countries reviewed all researches on smoking. They stated unanimously that even passive exposure to tobacco products can cause lung cancer in people who have never smoked. Tobacco is the leading cause of preventable cancers worldwide and half of these deaths because of smoking occur in middle age 35-69 years. The WHO hopes that its report will convince governments to act on controlling smoking in public places and to encourage people to stop.
