Smoking causes cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. Smoking also increases risk for tuberculosis, certain eye diseases, and problems of the immune system, including rheumatoid arthritis.

Nicotine enters your bloodstream, increasing your pulse and blood pressure. Your sense of smell is reduced. Because nicotine is a stimulant, your brain will release feel-good chemicals or make you want to eat. When you don’t satisfy the urge, you will feel anxious and irritable.

worst effects of smoking:

  • Lung Cancer. More people die from lung cancer than any other type of cancer

  • COPD (chronic obstructive pulmonary disease) COPD is an obstructive lung disease that makes it hard to breathe.

  • Heart Disease

  • Stroke

  • Asthma

  • Reproductive Effects in Women
