Illustration comparing the lungs and alveoli of a smoker (right) and of a non-smoker (left). Smoking can result in chronic obstructive pulmonary disease (COPD), emphysema, and cancer. Here, the smoker's lungs appear gray and the alveoli are significantly damaged (emphysema), while the non-smoker has healthy lungs and alveoli.
