Nearly seven in 10 smokers in the United States want to quit according to the Centers for Disease Control and often people try as a New Year’s resolution. Sarah Smith with Prelude Behavioral Services says she sees people who try to quit this time of year. Smith recommends those looking to stop using tobacco check out the free resource Quitline Iowa. The service offers free quit plans and counseling from “quit coaches.”

She explains within 20 minutes of your last cigarette blood pressure goes back to normal levels and after 12 hours of quitting the level of carbon monoxide in your blood drops back to normal. Also, after three months lung function greatly improves.
