Contingency Management for Smoking Cessation in Homeless Smokers
The purpose of this study is to examine the effectiveness of an internet-based contingency management program for smoking cessation in persons who are homeless. Thirty homeless smokers will be enrolled in the study. Participants will receive payment based on their own low carbon monoxide readings, which indicate being quit from smoking. Participants will be prescribed nicotine replacement (patches and either gum or lozenge)and bupropion. All participants will receive a four sessions of smoking cessation counseling, and will be trained to perform carbon monoxide monitoring with a device provided by the study. They will also be provided with a mobile phone equipped with a video camera, and will use this equipment at home to monitor their carbon monoxide . Participants will record videos of themselves taking a carbon monoxide reading and displaying the results, and will upload the videos to a secured website that is only accessible by the research team members and the participant. Payment will be based on providing carbon monoxide readings that indicate abstinence.
The study is designed to address the following aims:
Specific Aim 1: To evaluate whether it is feasible to use internet-based contingency management for helping smokers who are homeless stop smoking.
Specific Aim 2: To evaluate how effective internet-based contingency managementis on decreasing smoking in smokers who are homeless.

|Official Title:||Contingency Management for Smoking Cessation in Homeless Smokers|
- Breath carbon monoxide [ Time Frame: Throughout study - one year ]
- Saliva cotinine [ Time Frame: 2 months, 3 months, 6 months ]When the body processes nicotine, it produces cotinine. Cotinine can be found in saliva.
|Study Start Date:||January 2013|
|Study Completion Date:||September 2014|
|Primary Completion Date:||September 2014 (Final data collection date for primary outcome measure)|
Experimental: Active Contingency Management
All participants are assigned to a single arm, active contingency management. In this arm, participants are provided monetary rewards for remaining abstinent from smoking.
All participants who are medically eligible to take Bupropion will receive this study medication one week prior to their smoking quit date.
Other Name: ZybanDrug: Nicotine replacement therapy
All participants will receive two forms of nicotine replacement therapy - nicotine patches and a rescue method (either gum or lozenge).
