Smoking any cigarette is harmful to health! The most obvious harm is the damage to the respiratory system. The pseudo-stratified ciliated columnar epithelium on the wall of your trachea will produce a large number of goblet cells due to stimulation and metaplasia, and the trachea will lose its function of purifying and discharging pollutants, thus producing a large amount of mucus, and you will keep coughing. Not to mention the damage to lung function ~ And the latest research shows that smoking will greatly change human dna, and the chances of developing Alzheimer's disease in old age will greatly increase!
