Mouth and throat: Tobacco smoke can cause gum disease and tooth decay. The teeth become yellow or black.
Esophagus: The tars in smoke can trigger cancer.
Brain: Headaches are common. Lack of oxygen and narrowing of blood-vessels can lead to strokes.
Bronchi: Smoke contains hydrogen cyanide and other chemicals, which attack the lining of the bronchi, inflaming them and increasing susceptibility to bronchitis.
Lungs: People who inhale smoke are ten times more likely to get lung cancer than non-smokers. Mucus secretion is increased, causing chronic catarrh and smoker’s cough.
Circulation: Nicotine raises blood-pressure. Carbon monoxide leads to development of cholesterol deposits in artery walls, causing heart attacks and strokes. Loss of circulation in limbs can cause amputation.
