How does smoking affect health?

Smoking is a major health concern that significantly impacts both smokers and those around them.

Understanding the full scope of how smoking affects health can empower individuals to make informed decisions about their habits and lifestyle.

What Are the Health Effects of Smoking?

• Lung Cancer: Smoking is the primary cause of lung cancer, responsible for approximately 85% of cases.
• Asthma: Smoking can exacerbate asthma symptoms and trigger attacks.

Cardiovascular Health Risks

The cardiovascular system is significantly affected by smoking, increasing the risk of:

• Heart Disease: Smokers are two to four times more likely to develop heart disease than non-smokers.
• Stroke: Smoking doubles the risk of having a stroke.
• Peripheral Arterial Disease (PAD): This condition involves narrowed arteries and reduced blood flow to limbs.

Impact on Cancer Risk

Smoking is a leading cause of cancer across various parts of the body, including:

• Lung Cancer: As previously mentioned, smoking is the leading cause.
• Mouth, Throat, and Esophagus Cancer: The risk is significantly higher for smokers.
• Bladder and Pancreatic Cancer: Smoking increases the risk of these cancers.

Effects on Overall Health

Beyond specific diseases, smoking affects general health in numerous ways:

• Weakened Immune System: Smokers are more susceptible to infections.
