Effects of Smoking

Lung Cancer Smoking causes lung cancer. Lumps and tumours develop which are cancerous growth that block the air passages and causes suffocation.

Heart diseases Smoking makes blood clot more easily Walls of the blood vessels become damages and accumulate fat deposits The heart has to now pump faster and harder to maintain a normal blood flow Blood vessels may burst and the person may suffer a stroke Or if the blood supply is blocked the person may have a heart attack Smokers are 2 to 3 times more likely to have a heart attack than non-smokers

Bronchitis Smoking damages the cilia which are tiny hairs that line our air passages that trap dust and germs, so they now enter easily. This causes the dust to produce a lot of mucus which causes the person to cough continuously known as the smoker’s cough The air passages become inflamed and the person may suffer from bronchitis Bronchitis causes the person to not walk properly or even sleep properly.

Emphysema Smoking damages the air sacks in the lungs More air now has to be moved in and out of the lungs as the gas exchange surfaces are damaged The damaged lungs and the increased rate of breathing makes breathing very painful Emphysema prevents people from being active, some persons need a constant supply of oxygen even when sitting

Passive smokers Passive smokers are persons who do not smoke but who breathe in tobacco smoke from smokers . This smoke is also called second hand smoke Passive smokers suffer from sore eyes, smoker’s cough, headaches and lung cancer.
