Lung and esophagus cancer together claim 87,000 lives per year. On average someone who smokes a pack or more a day lives seven years less than a non-smoker. Tar lines the inside of your lungs, which in turn causes the cancer. Someone who smokes 20 cigarettes a day inhales at least one cup of tar per year. The combination of nicotine and carbon monoxide in each cigarette you smoke temporarily augments your heart rate and blood pressure, straining your heart and blood vessels. This in turn can cause a heart attack, or a stroke. Carbon Monoxide deprives your muscles, brain, and body tissues of oxygen making your heart labor harder. As time goes by your airways swell up and allows less air into your lungs. Three out of four deaths from heart disease in young people are caused by smoking. Smoking also causes fat deposits to narrow and obstruct blood vessels which excel heart attacks.
Lipor, oral activity, urinary bladder, and kidney cancer are some of the few cancers that all together claim 18,000 lives each year. One out of two life time smokers will die from their addiction. Emphysema, an illness that slowly rots your lungs is a result of smoking and causes shortness of breathe. Bronchitis usually comes along with this illness as well.
All in all smoking is pretty stupid if you tell me. And I definitely am not going to try it. Teens who smoke are three times more likely to consume alcohol, eight times more likely to use marijuana, and twenty-two times more likely to use cocaine. Smoking is also associated with a number of other risky behaviors such as fighting, and engaging in unprotected sex.
