In health class, I learned that smoking is bad for your heart.  If you smoke, eventually you may die.  Smoking is the leading cause of lung disease.  Smoking is an addiction and tobacco smoke contains nicotine, which is a drug that makes it very hard to quit smoking.  By quiting smoking you save money.  You will also be able to smell and breathe better.  It will lower your chances of getting heart disease, lung cancer, and stroke.  Don't let smoking ruin your heart and lungs!  Stay alive and don't smoke!
