Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung condition characterized by obstructed airflow, making it difficult to breathe. Smoking is the primary cause of COPD, with approximately 90% of cases attributed to tobacco use. The harmful chemicals in cigarette smoke damage the lungs' delicate air sacs and bronchial tubes, leading to inflammation and narrowing of airways. This chronic irritation triggers a cascade of destructive events, resulting in the loss of lung function over time. Quitting smoking is the most effective way to prevent COPD progression and improve respiratory health, underscoring the vital role of smoking cessation in managing this debilitating disease.
