Hi My answer will be a big NO . People recovering from lung cancer continue to have problems - pain, fatigue, and shortness of breath., depression and anxiety, even after treatment is completed. Moreover there is chance of relapse and nothing helps recovery more than stopping smoking. Smoking is a major cause of heart attack. Heart attack greatly increases with the number of cigarettes he or she smokes. Smokers continue to increase their risk of heart attack the longer they smoke as well. People who smoke a pack of cigarettes a day have more than twice the risk of heart attack than non-smokers. Regards Ranjit
