Brief Summary
Despite the availability of a variety of effective treatments for smoking cessation, uptake of treatments is low. The increasing use of smartphone technology presents an exceptional opportunity to expand access to low-cost smoking cessation services. In this pilot study, the investigators will use a text-messaging platform to test peer mentoring for smoking cessation, delivered by former smokers. While peer mentoring is a common approach to health behavior change, it has rarely been used to maximum effect by smoking cessation programs. The text-messaging platform serves as the basis for a randomized controlled trial to test the effectiveness of peer mentoring for smoking cessation. This pilot will include approximately 200 U.S. adult smokers who will be randomly assigned to a peer mentor or not. Participants in the control group will receive automated text messages used in SmokefreeTXT, a nationwide text-messaging service sponsored by the National Cancer Institute (NCI) in which users receive one to five automated messages per day for up to eight weeks. Smokers in the intervention group will receive a modified version of the same automated messages from SmokefreeTXT, but with additional personalized messages from an assigned peer mentor. Mentors will provide responses to specific questions or comments a smoker may have after receiving the automated messages. The intervention will last 8 weeks. The study includes primary outcomes to measure the acceptability, engagement, user experience, and early efficacy of the intervention.

Outcome Measures
Primary Outcomes (1)
Saliva test for cotinine
The primary measure of early efficacy is the 7-day point prevalence of abstinence measured 3 months after the quit day, using a saliva cotinine test. The saliva test results will be recorded through a series of photographs and shared with the study team via email or online upload. Participants who self-report having smoked in the last 7 days, as part of the follow-up survey, will be considered to be continuing smokers.

Study Arms (2)
Control Arm
ACTIVE COMPARATORParticipants will receive automated text messages drawn from the script used by SmokefreeTXT.
Peer Mentoring Arm
EXPERIMENTALParticipants will receive a modified version of the automated text messages sent to the control arm plus random assignment to a peer mentor.
Interventions
Participants will receive automated text messages used by SmokefreeTXT. The messages are designed to provide encouragement, support, and information about quitting smoking. Participants will receive 1-5 automated messages per day for 6-8 weeks depending on choice of quit date.
Participants will receive a modified version of the automated text messages sent to the control arm plus random assignment to a peer mentor. The modified messages include automated "conversation starters," designed to stimulate conversation with the peer mentor. The peer mentor will then send personalized, tailored responses. The peer mentor is a former smoker who has completed a training program developed by the investigator team. Participants will receive 1-5 automated messages per day for 6-8 weeks depending on choice of quit date.
