Smoking is a bad hobby, especially among men. It has become a very common phenomenon that people are addicted to cigarettes and smoke frequently for a long time.

1, carcinogenic

One of the most serious hazards of long-term smoking is cancer, which can increase the incidence of lung cancer, oral cancer, laryngeal cancer and other cancer diseases, especially squamous cell cancer, and women are prone to breast cancer.

Long-term heavy smoking may be a risk factor for a variety of cardiovascular and cerebrovascular diseases. Clinicopathological studies show that the incidence of coronary heart disease, hypertension and cerebrovascular disease in smokers is 5-6 times that of normal people. Nicotine and carbon monoxide in cigarettes and smoke can cause coronary atherosclerosis, affect the changes of blood lipid and platelet content, and cause myocardial hypoxia and vasoconstriction.

3. Damage to respiratory tract

Smoking will cause bad stimulation to bronchial mucosa and the whole respiratory tract, and there may be signs of damaged cilia, shortened cilia, increased mucus secretion, and emphysematous lesions in the lungs. Long-term smokers are prone to chronic cough, phlegm in pharynx and dyspnea, and suffer from spontaneous pneumothorax and chronic pharyngitis.

4, damage to the digestive tract

Because smoking will lead to an increase in gastric acid secretion and inhibit pancreatic secretion, it is prone to gastric acid, stomach pain and gastric ulcer. At the same time, it can obviously reduce the tension of lower esophageal sphincter, and even suffer from reflux esophagitis.

5. Other dangers

Smoking will not only make your face dull, but also damage your skin barrier, especially make your fingers and cheeks grow yellow spots or black spots. If women smoke for a long time, it will lead to menstrual disorder, and the incidence of ectopic pregnancy and threatened abortion will increase significantly.
