Smoking tea cigarettes is harmful to people. Tea cigarettes are smoked by using tea leaves as tobacco, and there is no nicotine in tea cigarettes. However, tea contains more carbohydrates, tea polyphenols, amino acids, etc. These nutrients are not resistant to high temperatures. When burned at high temperatures, the nutrients can be destroyed, resulting in more carbon monoxide, respirable particles, and tar. Among them, carbon monoxide and tar and other harmful substances can directly stimulate the respiratory mucosa and the lungs, lightly cause bronchitis and pneumonia in the lungs, and in the long term can also increase the incidence of lung cancer, stomach cancer and other cancers, which is very harmful to health. Therefore, it is not recommended to smoke either tea cigarettes or traditional tobacco.
