Long term effects of smoking Tobacco(20)

Coronary heart disease and stroke

Nicotine contracts the blood vessels, cutting down blood flow to the body's limbs. Nicotine also contributes to buildup in the blood vessels. This can lead to a condition called arteriosclerosis, or hardened arteries. The arteries may become clogged, increasing the risk of heart attack and stroke.

Chronic bronchitis

Over time, tobacco can damage the cilia in the bronchi until they become useless, leading to a buildup of tar in the lungs. The user develops a chronic cough and excessive mucus secretion.

Emphysema

Tobacco smoke destroys the tiny air sacs in the lungs. They become less elastic, making it difficult for the lungs to absorb oxygen. A person with advanced emphysema uses up to 80 percent of their energy just to breathe.

Weakened immune system

Weakened immune system. Long-term tobacco use weakens the immune system, leaving the body open to disease

Lung cancer

When the cilia in the bronchi have been destroyed, the lungs cannot expel excess mucus. As a result, cancerous cells can multiply, block the bronchi, and move to the lungs. 90% of lung cancer deaths are caused by smoking.
