Smoking is indeed a major cause of death worldwide. Here's a brief overview of why smoking is harmful and how it affects the body:

2. Heart Disease
- Cardiovascular Disease: Smoking increases the risk of heart attacks, strokes, and coronary artery disease.
- Atherosclerosis: Smoking damages arteries, leading to plaque buildup and narrowing.
3. Other Health Issues

5. Impact on the Body
