Health effects of tobacco
Health effects of tobacco
Health effects of tobacco (pronunciation: /ˈhɛlθ ɪˈfɛkts ɒv ˈtæbəkoʊ/) are the effects that use of tobacco has on human health. The term is derived from the Old French tobac, which in turn is borrowed from the Spanish tabaco, a term of uncertain origin.
Overview
Research has shown that tobacco use can lead to a variety of health problems, including lung cancer, heart disease, and chronic obstructive pulmonary disease (COPD). The harmful effects of tobacco are primarily due to the presence of nicotine, a highly addictive substance, and other harmful chemicals.
Health effects
Lung cancer
Tobacco use is the leading cause of lung cancer, accounting for about 85% of all cases. The risk of developing lung cancer is significantly higher in smokers than in non-smokers.
Heart disease
Tobacco use increases the risk of heart disease by damaging the lining of the arteries, leading to a buildup of plaque that can cause heart attacks and strokes.
Chronic obstructive pulmonary disease (COPD)
Tobacco use is a major risk factor for chronic obstructive pulmonary disease (COPD), a group of lung diseases that block airflow and make it difficult to breathe.
