It is usually not recommended to smoke again after being cured of neocoronavirus. After being infected with the New Crown Virus, the main site of attack is the lungs, which will cause inflammatory changes, exudative and interstitial changes in the lungs, and may even lead to respiratory difficulties in severe cases. After the patient is cured and discharged from the hospital, although the body functions and lung functions have basically recovered, the lungs are still relatively fragile at this time due to a longer period of attack by the new coronavirus. When smoking, harmful substances such as nicotine and tar contained in cigarettes will enter the lungs and cause damage to the lungs. Continuing to smoke after the new coronavirus has been cured will cause great damage to the lungs and seriously affect the self-repair of the lungs. After a new crown is cured, patients should develop good living habits and avoid unhealthy lifestyles such as smoking, drinking and staying up late. When the body again appears uncomfortable symptoms after the cure, should promptly seek medical attention.
