Lung cancer patients who continue to smoke after diagnosis are at increased risk of treatment toxicity, residual/recurrent disease, future malignancies, and all-cause mortality. Guidelines including those from National Comprehensive Cancer Network and Cancer Care Ontario advocate for screening, counseling, and access to smoking cessation services for all cancer patients;  however, barriers from both patient and health care professional (HCP) perspectives contribute to lack of implementation.
