It\'s not easy to quit smoking, but it could be the most important decision anybody ever makes, U.S. health officials said. The Centers for Disease Control and Prevention in Atlanta began a new campaign -- Tips from Former Smokers -- to show just how harsh tobacco can be, via smoking or by secondhand smoke. \"Quitting smoking, or never starting, is so vital to your health,\" CDC officials said in a statement. \"For example, Suzy was 15 when she started smoking. When she was 57 she suffered a stroke.\" Most know that people could get cancer from smoking, but some might not know smoking is also linked to heart disease, stroke, asthma and other diseases, the CDC said. \"Apparently, a lot of people don\'t know smoking can cause a stroke,\" Suzy said. \"It can. It caused mine. I used to love to travel. Now, I can\'t leave the house by myself. And I can\'t drive anymore.\" CDC offers free resources to help people to quit smoking.
