-The lungs of smokers are damaged after prolonged use of cigarettes because cigarette smoke contains many harmful chemicals, including tar, carbon monoxide, and various carcinogens. These chemicals irritate and inflame the lungs, leading to chronic bronchitis, emphysema, and other respiratory problems. Over time, smoking can also cause damage to the tiny air sacs in the lungs known as alveoli, which can lead to reduced lung function and an increased risk of lung cancer. The longer a person smokes and the more cigarettes they smoke, the greater the damage to their lungs is likely to be.
