The main reason for throat discomfort from smoking is that the harmful substances in the process of smoking will stimulate the local throat causing local congestion and edema, and will also cause lymphatic hyperplasia, which will easily cause chronic throat inflammation, and will show a foreign body sensation, and will also cause nausea, vomiting, and even local pain in the throat, which may also induce cancer over time. It is necessary to quit smoking in time. In addition to the effect on the throat, it can also stimulate the trachea and lungs, causing chronic bronchitis, chronic obstructive pulmonary disease, and even induce lung cancer, which can seriously affect the health of the body, and also stimulate the stomach, causing reflux esophagitis and chronic gastritis, which may also lead to throat discomfort.
