Measure
iCOMMIT
Components include: 1. mobile contingency management (mCM): Participants provide video recordings of themselves taking carbon monoxide readings to confirm smoking abstinence. 2. pharmacotherapy for smoking cessation: Includes nicotine replacement therapy \[nicotine patch and one nicotine rescue method (e.g., nicotine gum, lozenge, inhaler)\] and bupropion (150 mg/daily for days 1-7 and 300 mg/daily thereafter) 3. 4 sessions cognitive-behavioral smoking cessation counseling; 4. Stay Quit Coach: Stay Quit Coach is a smart phone application that provides support and information for adults who are already in treatment to quit smoking and to help them stay quit after treatment. 5. SMS text messaging: Patients assigned to this condition will receive text messages relevant to their current status in their smoking quit attempt.
Control Group
Components include: 1. pharmacotherapy for smoking cessation: Includes nicotine replacement therapy \[nicotine patch and one nicotine rescue method (e.g., nicotine gum, lozenge, inhaler)\] and bupropion (150 mg/daily for days 1-7 and 300 mg/daily thereafter) 2. 4 sessions cognitive-behavioral smoking cessation counseling;
