Aims: To identify the predictors associated with smoking cessation in smokers under treatment for alcohol and/or cannabis treated in drug treatment centers (DTC). Methodology: Mixed methods project with qualitative and quantitative designs (three studies). Study I discussion groups: of clinical professionals of DTC to explore the barriers/facilitators of these smokers in quitting and the interventions carried out. Study II Prospective cohort of smokers in alcohol and/or cannabis treatment that will be followed-up for 12 months. Sample size: difference in incidence (exposed to cessation interventions versus non-exposed = 12 per 100 years), α = 0.05, β = 0.10, losses = 20% (n = 726). Dependent variables: self-reported and verified tobacco consumption abstinence, quit attempts, motivation, and self-efficacy. Independent variables: age, sex, the substance under treatment. Analysis: incidence, relative risk and simple and multiple logistic regression models (odds ratio and confidence interval, CI, 95%) of quitting. Study III discussion groups: with smokers under alcohol and/or cannabis treatment selected according to their typology. Analysis: of thematic content and triangulation qualitative and quantitative results. Expected results: Characterization of variables that influence tobacco cessation, to improve the design of interventions.
