Smoking among PLWHA is a critical public health issue, with the rate of smoking 2-3 times greater than it is in the general population and the health risks of smoking outweighing those associated with the virus itself. Unfortunately, remarkably few studies have evaluated smoking cessation interventions for PLWHA and the available literature indicates that both behavioral and pharmacological smoking cessation interventions yield modest effect sizes and quit rates that are considerably lower than in the general population. A sizable literature, including studies by our research team, indicates that using the nicotine metabolite ratio (NMR) to personalize the selection of medications for tobacco use and the MAPS intervention to augment adherence to these medications can optimize treatments for tobacco use among PLWHA. The NCI recognized the potential for clinicians to use the NMR to individualize cessation treatment in order to improve effectiveness (https://www.cancer.gov/about-nci/budget/plan/public-health) and the Centers for Disease Control and Prevention (CDC) has endorsed MAPS as an evidence-based approach to increasing medication adherence among PLWHA. As such, this trial will test these intervention optimization strategies to determine if individually or together they can represent an effective approach to treating tobacco use in this under-served population of smokers. As a major advance for this area of work, the investigators will use rigorous methodology to evaluate these optimization strategies (i.e., a randomized design, biological verification, an ITT approach, and 6-month outcome assessments) and, overall, our approach is consistent with the multiphase optimization strategy (MOST) framework, which has been used to identify intervention components that maximize cessation outcomes. This trial will also assess theoretically derived and empirically based mechanisms through which these optimization strategies affect cessation and explore sub-groups who are more or less responsive to these strategies. In the end, this trial, which is consistent with the Office of AIDS Research trans-NIH Strategic Plan for HIV and HIV-Related Research (https://www.oar.nih.gov/hiv-policy-and-research/research-priorities), will determine if getting the right medication to the right person and making sure they adequately use the medication optimizes tobacco cessation treatments among PLWHA as a critical way to improve health outcomes for this population.
