Smoking damages the alveoli, the tiny air sacs in the lungs responsible for gas exchange. It leads to inflammation and the destruction of alveolar walls, reducing their surface area and making it harder for oxygen to enter the bloodstream. This damage can contribute to chronic obstructive pulmonary disease (COPD) and emphysema, resulting in decreased lung function and respiratory difficulties. Over time, the accumulation of tar and toxins from smoking can also increase the risk of lung infections and other respiratory illnesses.
