Smoking and Its Health Effects

What is Smoking?

Smoking involves inhaling and exhaling smoke from burning tobacco products, such as cigarettes, cigars, and pipes. Tobacco contains nicotine, a highly addictive substance that makes quitting difficult.

Smoking introduces over 7,000 harmful chemicals into the body, including tar, carbon monoxide, and formaldehyde—many of which are toxic and carcinogenic.

Health Risks of Smoking

Smoking is associated with numerous life-threatening conditions, including:

1. Lung Diseases

• Lung Cancer – Smoking is the leading cause of lung cancer, responsible for 85% of cases.
• Chronic Obstructive Pulmonary Disease (COPD) – Causes chronic coughing, breathlessness, and lung damage.
• Emphysema – Destroys the lung’s air sacs, making it difficult to breathe.

2. Heart and Blood Vessel Diseases

• Heart Disease – Smoking increases plaque buildup in arteries, raising the risk of heart attacks.
• High Blood Pressure – Nicotine narrows blood vessels, forcing the heart to work harder.
• Stroke – Reduced blood flow to the brain can lead to paralysis or death.

3. Cancers Linked to Smoking

• Lung cancer
• Mouth, throat, and esophageal cancer
• Pancreatic cancer
• Bladder and kidney cancer

4. Weakened Immune System

Smoking makes the body more vulnerable to infections, slows healing, and increases the risk of autoimmune diseases.

Secondhand Smoke: Risks to Non-Smokers

Even non-smokers can suffer serious health issues due to secondhand smoke, which contains over 250 harmful chemicals. Risks include:

• Children: Increased risk of asthma, pneumonia, and sudden infant death syndrome (SIDS).
• Adults: Higher risk of heart disease, lung cancer, and stroke.
• Pregnant Women: Secondhand smoke exposure can cause low birth weight and birth defects.

Quitting smoking is difficult but achievable with the right approach. Here are proven methods to help you quit:
