Look it up on WEBMD. It is a Doctor's reference

Hi.
Yes that is true but it also depends on how long a person has been smoking and how much. Another good reason to quit!

Once the damage to the lungs is done, there is no reversing it. My doctor still considers me a smoker and requires regular chest Xrays after quitting 40 years ago!
