Question

How does smoking harm passive smokers?

Answer 1

1. Damaging Lungs and Causing Breathing Problems:
   Passive smoking irritates the lungs. It can cause-

   • Coughing, wheezing, and breathlessness

   • Reduced lung function, especially in children

   • Increased risk of bronchitis and pneumonia

2. Increasing Risk of Heart Disease and Stroke:
   Even occasional exposure to second-hand smoke-
   

   • Narrows blood vessels and increases blood pressure

   • Leads to plaque buildup in arteries

   • Increases chances of heart attacks and strokes

3. Raising Cancer Risk:
   Passive smoke contains over 70 cancer-causing chemicals. It increases the risk of-
   

   • Lung cancer (even in lifelong non-smokers)

   • Possibly throat, breast, or bladder cancers

4. Harming Children:
   Children are more vulnerable due to smaller lungs. Passive smoking can cause-

   • Asthma attacks or trigger wheezing

   • Ear infections and frequent colds

   • Poor lung development and weakened immunity
