To a certain extent. Fortunately, lungs can heal and regenerate to repair themselves to a certain extent but cannot reverse permanent damage. A review has described the adult lung as having the ability to regenerate after injury. Even after quitting smoking, the lungs can repair injury and remove toxins to improve respiratory function. But there is no way to reverse lung damage that has resulted in scarring.
The American Cancer Society (ACS) website says that the effects of quitting smoking on the lungs begin to show within two weeks to three months. THIP MEDIA has shown that we can reverse the damage caused to lungs by smoking to a certain extent only.
However, conditions like emphysema or chronic bronchitis, which together constitute chronic obstructive pulmonary disease (COPD), cannot be reversed.
