There is no medication that can clear the lungs of long-term smoking, so you need to stop smoking immediately and check for any lung disease caused by long-term smoking and treat it accordingly.
Long-term smoking can cause damage to the lungs, leading to a variety of lung diseases. There are no medications that can remove the damage to the lungs caused by smoking or prevent smoking-induced lung diseases, so the main measure is to quit smoking immediately.
Long-term smokers may need to undergo regular chest CT, lung function and other related tests to screen for lung cancer, chronic obstructive pulmonary disease and other related diseases, and to intervene as early as possible to improve the patient’s clinical outcome.
In summary, long-term smokers are not reliant on medications to clear their lungs, and need to be monitored by immediate smoking cessation and regular physical examinations and other related means.
