When people smoke cigarettes for the first time, the nicotine may make them feel sick to their stomach and dizzy. Smokers often find they need a second cigarette, and another and another, in order to get the same feelings. After awhile, they find the number of cigarettes that keeps them satisfied. At that point, the person is physically addicted and will only feel comfortable when nicotine is in his or her system. One in four smokers dies early because of his or her smoking.
Smokers die of heart disease, cancer and emphysema.
What's more, research shows that secondhand smoke, the smoke from other people's cigarettes, can harm the health of nonsmokers. Breathing in another person's smoke can cause many breathing problems in children and cancer and heart disease in adults. The trend now is for public places and work places to go smoke free. This should help smokers make the move to quit and keep everyone's lungs healthier. They are easy to buy and inexpensive compared to other drugs.
