If you have a cough that is caused by smoking, you need to quit smoking and seek medical attention to rule out lung-related diseases. 1. If you have a hacking cough, the main cause is smoking. Tobacco can damage the trachea, bronchial tubes and lung tissues, resulting in damage to their mucous membranes and normal function, as well as an increase in sputum secretion, which can lead to coughing. 2. At the same time do not rule out the possibility of lung diseases, including pneumonia, chronic obstructive pulmonary disease, bronchial asthma, lung cancer, etc., can cause long-term cough symptoms. Therefore, it is recommended to consult a doctor in time for lung X-ray, blood routine, tumor markers, sputum culture and other tests. 3. It is recommended to quit smoking immediately, and to clarify the cause of coughing and then target treatment. For example, antibiotics such as ceftriaxone should be considered for respiratory infections, albuterol should be considered for bronchial asthma to dilate the bronchial tubes, and surgical resection should be evaluated for lung cancer, etc., depending on the doctor’s recommendation.
