An Airman blows vapor into the air at Warrensburg, MO, Oct. 2, 2019. According to the Centers for Disease Control and Prevention, e-cigarettes produce an aerosol by heating a liquid mixture of nicotine, flavorings or other chemicals which users then inhale. Members should learn the risks they take when choosing to vape and they’re encouraged to use the 509th Medical Group’s resources for quitting smoking or vaping. (U.S. Air Force photo by Staff Sgt.
