 Patients will be followed up for 52 weeks after starting the treatment. Participants in both groups will receive a follow up visit by the study coordinator or a research assistant during their hospital stay i.e., at discharge for day surgery patients or at 24 hrs after their surgery. Patients in both groups will receive weekly follow up calls during the first 4 weeks and then at the end of 8 week after starting the treatment. At the end of treatment period, i.e. 12 weeks patients will come be visited in the hospital. For the rest of follow-up period, i.e. until the end of week 52, patients will receive phone calls for every 4 weeks to help support abstinence and to report smoking status. Focus will be on the second week following start of abstinence as it has been shown that abstinence of smoking at 2 wks after a cessation attempt is highly predictive of success. The self reports of smoking status at 24- and 52-week follow-up will be verified by measuring COE and urine cotinine.
