Regular smoking is particularly harmful to the body. Smoke from smoking can irritate the throat area and can easily cause chronic pharyngitis, which can lead to irritating coughs and, in severe cases, may also cause mucosal damage and symptoms of laryngeal edema and blood in the sputum. It will also easily irritate the trachea and lungs and develop chronic bronchitis. Because tobacco contains a lot of tar and nicotine, these harmful substances will be deposited in the lungs, and over time, it may also cause lung cancer. Frequent smoking also has an effect on the cardiovascular and cerebrovascular, inducing a variety of cardiovascular and cerebrovascular diseases, even if it is second-hand smoke. Try not to smoke again, and even less when you are in public places.
