There are many harmful effects of tobacco products, both for the individual and for society as a whole.
For individuals, the two most significant effects are increased risk of developing cancer and heart disease. Tobacco smoke contains over 7,000 chemicals, including over 70 known carcinogens. The prolonged inhalation of these chemicals increases the risk of developing cancer, particularly lung cancer, and can lead to other types of cancer, such as throat and mouth cancer. In addition, the chemicals in tobacco smoke can damage the cardiovascular system, causing narrowing of the arteries, thickening of the artery walls, and increased risk of stroke and heart attack.
The effects of tobacco extend beyond the individual, to their family and society as a whole. Second-hand smoke, which is the smoke exhaled from a smoker or generated from burning tobacco products, puts the health of non-smokers at risk. The inhalation of second-hand smoke causes increased risk of developing cancer and heart disease, as well as respiratory problems, such as asthma and bronchitis. In addition, tobacco products are a major burden on the healthcare system. They are responsible for billions of dollars in medical costs, lost productivity, and premature death each year.
