No one should smoke. According to the CDC, smoking leads to disease and disability and harms nearly every organ system of the body. Cigarette smoking is a risk factor for lung cancer. It is the leading cause of preventable death.
Smoking can trigger asthma. Cigarette smoke irritates the lungs, causing redness, swelling and more mucus. Your lungs have a natural defense to keep dirt and germs out. Cigarette smoke destroys lung tissue and breaks down these defenses. This puts people with asthma in a precarious spot, because those changes to the lungs cause symptoms and asthma episodes.
Frequent asthma attacks can cause changes to the lungs over time and lead to more severe disease, chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, or asthma-COPD overlap.
If you have asthma and smoke, please consider smoking cessation.
