There is no evidence to prove that smoking can prevent novel coronavirus pneumonia. Moreover, some reports claim that the nicotine content in tobacco is more irritating to the lungs and may aggravate dyspnea or the clinical manifestations of novel coronavirus pneumonia, so it is important to adopt a more correct preventive approach. Smoking is harmful to health, and smoking is one of the main factors in the development of lung cancer. It is recommended to minimize or quit smoking, and to do a good job of self-protection, because after all, you can’t wear a mask when you smoke. You should wear a good mask when you go out, wash your hands frequently, do not go to densely populated places, ventilate your room frequently for more than 30 minutes in the morning and more than 30 minutes in the evening, exercise appropriately to improve your resistance, and wear a mask or disinfect with alcohol can play a role in preventing the virus. Coronavirus can be spread through droplets in the air or through close contact, so try not to go to places with a large flow of people, and smoking is not an effective way to prevent and control the virus.
