RecruitingBehavioural interventionUrban and Reservation Implementation of All Nations Breath of LifeThis is an implementation trial of the All Nations Breath of Life (ANBL) smoking cessation program, which has already been tested for efficacy in reservation populations and shown feasibility in urban populations. It includes four implementation sites, two reservation sites and two urban sites. Therefore, investigators plan to test efficacy simultaneously. Implementation will follow guidelines described in the protocol, with all sites implementing certain parts of the intervention the same way, with the freedom to modify some aspects of the intervention for appropriate use in their communities. Statistical considerations are described in the appropriate section.
