There's no way around it. Smoking is bad for your health. Smoking harms nearly every organ of the body. Cigarette smoking causes 87 percent of lung cancer deaths. It is also responsible for many other cancers and health problems. These include lung disease, heart and blood vessel disease, stroke and cataracts. Women who smoke have a greater chance of certain pregnancy problems or having a baby die from sudden infant death syndrome (SIDS). Your smoke is also bad for other people - they breathe in your smoke secondhand and can get many of the same problems as smokers do.
Quitting smoking can reduce your risk of these problems. The earlier you quit, the greater the health. You don't have to be a smoker for smoking to harm you. You can also have health problems from breathing in other people's smoke. Secondhand smoke is the combination of smoke that comes from the burning end of a cigarette, cigar or pipe and the smoke exhaled by the smoker. Secondhand smoke contains more than 50 substances that can cause cancer. Health effects of exposure to secondhand smoke include lung cancer, nasal sinus cancer, respiratory tract infections and heart disease.
Why you should quit
Tobacco use is the most common preventable cause of death. About half of the people who don't quit smoking will die of smoking-related problems. Quitting smoking is important for your health and provides many benefits. Soon after you quit, your circulation begins to improve, and your blood pressure starts to return to normal. Your sense of smell and taste return and breathing starts to become easier. In the long term, giving up tobacco can help you live longer. Your risk of getting cancer decreases with each year you stay smoke-free.
