BackgroundWith the highest cancer incidence and mortality rates in the country, rural Appalachia has experienced a decades-long health decline, due in part to high smoking rates. Cigarette smoking prevalence exceeds 30% in much of the region. Oral nicotine pouches (ONPs), which contain nicotine but no tobacco, present an unexplored opportunity to reduce cigarette smoking and cancer incidence.
ObjectivesWe outline the protocol for the Appalachian Research to Impact Smoking’s Effects (ARISE) study, a randomized controlled trial to determine whether ONPs affect cigarette smoking patterns short- and long-term, and to evaluate their abuse liability versus nicotine replacement therapy (NRT) in a large sample of Appalachian smokers (clinicaltrials.gov: NCT06763536).
MethodsBetween 2025 and 2029, we will recruit 1,000 adult smokers living in rural Appalachian counties across 11 states. Participants will be identified via media outreach, mobile cancer screening, community events, and respondent-driven sampling, then randomized to ONP or NRT and complete four study phases: Baseline, Sampling, Switch, and Observation. In the Sampling phase, participants will receive varied flavors and nicotine strengths of their assigned product and select preferred options for use. During the Switch Phase, they will attempt to quit smoking and switch completely to their assigned product. The Observation phase will monitor tobacco use after discontinuation of study products. Study procedures will be conducted online and by mail, including surveys, expired carbon monoxide verification, and product delivery. The primary outcome is 7-day biochemically verified cigarette abstinence at the end of the Switch Phase. Secondary outcomes include switching rates, product appeal, craving, withdrawal, dependence, and purchases during the Observation phase. An intention-to-treat log-binomial regression model will estimate the effect of intervention assignment on cigarette abstinence.
ConclusionsResults will inform whether and how ONPs should be regulated, approached clinically, and used in public health interventions to reduce the burdens of cigarette smoking in Appalachia.
Alcohol is consumed by an estimated 137.4 million people in the USA 12 years of age and older and, as a result, is estimated to have caused about 140 thousand deaths among people 20 to 64 years of age each year from 2015 up to and including 2019.
The proposed review of the evidence on alcohol’s impact on health aims to produce conclusions to inform the Dietary Guidelines for Americans, 2026–2030. A multi-method approach will be utilised to formulate conclusions on (i) weekly (ie, average) thresholds to minimise long-term and short-term risks of morbidity and mortality, (ii) daily thresholds to minimise the short-term risk of injury or acute illness due to per occasion drinking, (iii) alcohol use among vulnerable populations (eg, pregnant women) and (iv) situations and circumstances that are hazardous for alcohol use. To inform expert decisions, this project will also include a systematic review of existing low-risk drinking guidelines, a systematic review of meta-analyses which examine alcohol’s impact on key attributable disease and mortality outcomes, and of estimates of the lifetime absolute risk of alcohol-attributable mortality and morbidity based on a person’s sex and average level of alcohol use. The systematic reviews were designed in accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). The preliminary conclusions produced as a result of this project will undergo public consultation, and data from these consultations will be qualitatively analysed. The results of the public consultations will be used to further revise and refine the project’s conclusions.
The study was granted an ethics exemption as only secondary data sources and unidentifiable public consultation will be utilised. Systematic reviews are pre-registered with PROSPERO (registration numbers CRD42024584924 and CRD42024584948).
This project will establish a scientific consensus concerning alcohol’s impact on health. This consensus is imperative for informing the upcoming Dietary Guidelines for Americans, 2026–2030, and for better informing individuals about the health risks associated with alcohol use.
