Smoking has severe and far-reaching effects on long-term health, damaging nearly every organ in the body. It’s one of the leading preventable causes of death worldwide.
🚭 Key long-term effects of smoking:
🫁 1. Lung diseases
-
Chronic Obstructive Pulmonary Disease (COPD): Smoking is the leading cause of COPD, which includes emphysema and chronic bronchitis.
-
Lung cancer: Smoking causes about 85–90% of all lung cancer deaths.
-
Asthma: Worsens symptoms and frequency of attacks.
❤️ 2. Cardiovascular disease
-
Smoking damages blood vessels, raises blood pressure, and lowers oxygen in the blood.
-
Increases the risk of heart attacks, strokes, and peripheral artery disease.
🧬 3. Cancer (not just lungs)
Smoking is linked to at least 15 types of cancer, including:
-
Mouth, throat, and esophagus
