The harmful effects of smoking on health and well-being
Clearly, cigarettes have a major impact on the lungs. An estimated 85% of cases of chronic obstructive pulmonary disease (COPD) and of lung cancer are caused by smoking. About a third of all cancer cases are due to smoking, including:
- Cancer of the esophagus
- Cancer of the mouth
- Cancer of the uterus
- Bladder cancer
- Stomach cancer
- Pancreatic cancer
Tobacco use is also a significant cause of heart disease. In fact, smoking considerably increases the risk of heart attack and stroke.
Smoking can also affect fertility. In addition, smoking during pregnancy can adversely affect fetal development, for example, increase the likelihood of premature birth and low birth weight.
