Study Arms:
- Arm A (bupropion hydrochloride) (Type: EXPERIMENTAL): Patients receive bupropion hydrochloride PO for 3 days and then BID for up to 1 year post RT/CRT.
- Arm B (varenicline, NRT) (Type: ACTIVE_COMPARATOR): Patients receive smoking cessation treatment tailored to individual smokers based on preference, smoking history and contra-indications. Patients are given the choice of one of the NCCN-recommended first-line pharmacotherapy options for smoking cessation comprised of varenicline PO daily for 1 week and then BID for 12 weeks or combination of nicotine patch and acute NRT for 12 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Treatment with varenicline or NRT can be extended up to 6 months to 1 year as needed.
