People Smoke example essay topic
There are many reasons why people start to smoke, but is it worth it to start? Cigarette smoking causes a variety of life-threatening diseases, including lung cancer, emphysema, and heart disease. An estimated 430,000 deaths each year are directly caused by cigarette smoking. Smoking is responsible for changes in all parts of the body, including the digestive system. This fact can have serious consequences because it is the digestive system that converts foods into the nutrients the body needs to live. Smoking has been shown to have harmful effects on all parts of the digestive system, contributing to such common disorders as heartburn and peptic ulcers.
It also increases the risk of Crohn's disease and possibly gallstones. Smoking seems to affect the liver, too, by changing the way it handles drugs and alcohol. In fact, there seems to be enough evidence to stop smoking solely on the basis of digestive distress. Smoking one cigarette immediately raises a person's blood pressure and heart rate and decreases the blood flow to body extremities such as the fingers and toes.

Appetite, taste and smell are weakened. Smokers typically experience shortness of breath, persistent coughs, reduced fitness, yellow stains on fingers and teeth and decreased sense of taste and smell. Smokers have more colds and flu than non-smokers and find it harder to recover from minor illnesses. Smoking can cause impotence in men, while women who smoke are less fertile than non-smokers. People who smoke tend to have facial wrinkles appearing much earlier and, in general, look older than non-smokers of the same age. Smokers have an increased risk of developing respiratory infections such as pneumonia and chronic bronchitis; emphysema; heart attack and coronary disease; cancer of the lung, throat, mouth, bladder, kidney, pancreas, cervix, stomach; stomach ulcers; and peripheral vascular disease due to decreased blood flow to the legs.
