Smoking causes many serious diseases including cardiovascular disease (heart disease), lung cancer, and chronic obstructive pulmonary disease (emphysema, chronic bronchitis). Smokers are far more likely to become sick with one of these diseases than non-smokers. Smoking is also addictive and can be extremely difficult to stop. These are the views of every leading medical and scientific organization around the world. And they are the views of Philip Morris International.
Public health authorities have concluded that smoking causes many other diseases.
