Can the damage from smoking be undone?
Eventually, the body is able to clean the lungs after a person stops smoking. Doctors say it can take many years for a smoker’s lungs to return to normal after they quit smoking. The longer the person smoked, the longer it will take for their lungs to get healthy. But, the lungs do begin to return to their natural pink shortly after smoking is stopped. The damage to the heart also gets better over time. Generally, ten years after a person stops smoking, the risk is 1/3 lower than if the person had continued smoking.
