According to WHO data, almost 8 million people die each year due to smoking and exposure to tobacco smoke. More than 7 million of those deaths are the result of direct tobacco use while around 1.2 million are the result of non-smokers being exposed to second-hand smoke. WHO data suggests that combustible cigarettes kill up to half of their users.
Numerous studies have shown that there is a cause-and-effect relationship between this addiction and the development of various diseases. Smokers are more likely to develop: cancers of the mouth, throat, larynx, lungs, and other organs, cardiovascular diseases, strokes, respiratory diseases (e.g. chronic obstructive pulmonary disease), Crohn’s disease, osteoporosis, Alzheimer’s disease as well as cervical, pancreatic and kidney cancer.
