1. Lung cancer: One of the causes of lung cancer is smoking. Tobacco smoke contains cancer-causing tars, nitrosamines, polynuclear hydrocarbons, etc. These substances enter the lungs during smoking and cause cancer.
2. Pleurisy: Inflammation of the lining of the lungs or pleura is called pleurisy. Nicotine in tobacco causes the lung pleura to swell and produce fluid pus. It disturbs breathing.
3. Bronchitis: It is called bronchitis when mucus accumulates in the trachea or lungs. Carbon monoxide in cigarette smoke paralyzes the cilia of the trachea and bronchi. So much cilia keep swinging.
4. Emphysema: Cigarette smoke destroys the walls of the alveoli and creates empty spaces in the lungs. This is called emphysema. In this disease, the respiratory area of the lungs decreases and the elasticity decreases.
5. Tuberculosis: Excessive smoking causes tuberculosis.
6. Heart attack: Carbon monoxide is absorbed in the hemoglobin of the smoker’s blood. Carbon monoxide helps cholesterol build up inside the arteries. It narrows the arteries and causes a heart attack.
7. Fibrosis: Thickening of the lung wall is called fibrosis. Smoking thickens the thin walls of the lungs and impairs breathing.
8. Whooping cough: Mucus comes out of the lungs due to smoking. It is called Udgari cough.
9. Chest pain and vomiting: Smokers have chest pain and vomiting.
10. Corona: Lungs of smokers are damaged. Therefore, if infected with corona, the possibility of death is high.
