Smoking itself causes damage to the respiratory tract and is not recommended no matter what the time period, which is not necessarily related to the occurrence of an epidemic. The occurrence and spread of the epidemic lies in the fact that the novel coronavirus can be transmitted through respiratory droplets and contact. Firstly, people smoke without masks and if they have conversations, they do not keep a safe distance, increasing the possibility of respiratory droplet transmission. Secondly, the risk of contact transmission is also increased by the fact that people often gather together to smoke. Smoking is one of the main triggers of chronic bronchitis, emphysema, and chronic airway obstruction, and smokers should not only pay extra attention during an epidemic, but should also quit smoking in a timely manner.
