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.
Quitting is not easy. You may have short-term effects such as weight gain, irritability and anxiety. Some people try several times before succeeding. There are many ways to quit smoking. Some people stop "cold turkey." Others benefit from step-by-step manuals, counseling or medicines or products that help reduce nicotine addiction. Your health care provider can help you find the best way for you to quit.
