Interventions
6-week smoking cessation program delivered via daily text messages SMS Turkey: 6-week smoking cessation program delivered via text messaging. SMS Turkey content is guided by the Cognitive Behavioral Therapy (CBT) theory. Content was tailored based on participant's stage in quitting (i.e., pre-quit, quit day, early-quit, late-quit, relapse). Based on the typical relapse trajectory, content paths were created for participants based on whether or not they were smoking 2 days after quit day; and again at 7 days after quit day. Depending on the participant's content path, the total number of messages received ranged from 91 (for those assigned to the encouragement arm) to 146 (for those who relapsed and then were assigned to the late quit messages).

Limitations and Caveats
An imbalance favoring the intervention was detected after approximately 100 participants were enrolled. To ensure a 1:1 match, the procedure was modified so that the RA pulled a slip of paper from a hat that read either "SMS Turkey" or "brochure."
