 Any interruption in the treatment which might happen due to patient surgical conditions e.g. patients having abdominal surgeries, etc. will be recorded for taking into account in the final sub-analysis. The second counseling session will be at discharge for day-surgery patients or at 24 hrs after other surgeries. Participants will be visited by the study coordinator in the hospital to review smoking status and to encourage future abstinence. The self-reported preoperative abstinence will then be verified by measurement of expired carbon monoxide COE and urinary cotinine in all patients. Patients will receive counseling with special emphasis on the skills associated with relapse prevention and remaining abstinent during second week as research suggests that abstinence during that time period is highly predictive of success Kenford et al 1994 and promotes surgical healing Warner et al 2004. Patients will also be informed of benefits of long-term cessation and will be encouraged to continue pharmacotherapy.
