The harm of smoking is well known. As many as 2.5 million people die from smoking every year in the world, and smoking is the first killer of mankind. Consciously developing the personal hygiene habit of not smoking is not only beneficial to health, but also the embodiment of noble public health ethics. In the smoking room, especially in the environment with closed doors and windows in winter, the room is not only filled with carbon dioxide exhaled by human body, but also with carbon monoxide exhaled by smokers, which will make people feel headache, burnout and work efficiency decline. More seriously, the contents of tar and nicotine in the cold smoke exhaled by smokers are 1 times higher than those in the hot smoke inhaled by smokers, and benzopyrene is 2 times higher, carbon monoxide is 4 times higher and ammonia is 50 times higher.

The data show that the incidence of lung cancer, laryngeal cancer and coronary heart disease in long-term smokers is 10-20 times, 6- 10 times and 2-3 times higher than that in non-smokers respectively. The incidence of circulatory system is 3 times higher, and the incidence of tracheitis is 2-8 times higher. Some people surveyed 1000 families and found that children under the age of 16 in smoking families suffered from more respiratory diseases than children in non-smoking families. Among children under 5 years old, 33.5% of non-smoking families have respiratory symptoms, and 44.5% of smoking families have respiratory symptoms.

In addition, smoking is related to the occurrence of lip cancer, tongue cancer, oral cancer, esophageal cancer, gastric cancer, colon cancer, pancreatic cancer, renal cancer and cervical cancer. Clinical research and animal experiments show that carcinogens in smoke can also affect the fetus through the placenta, leading to a significant increase in the incidence of cancer in its offspring.

..... Smoking harms others and yourself, and we should consciously form a good health habit of not smoking.
