Cigarette and E-Cigarette Retail Marketing on and Near California Tribal Lands
Open accessAbstract
Introduction. Retail settings are major channels for the tobacco industry to market commercial tobacco products. However, few studies have examined marketing strategies on Tribal lands. The resulting evidence is important, especially given that American Indian/Alaska Native (AI/AN) youth and adults have the highest smoking prevalence of any racial/ethnic group in the United States. In this study, we examined cigarette, e-cigarette, and vape/vaporizer availability, advertising, and price-reducing promotions in retail settings on and within a 1-mile radius of Tribal lands in California. Method. Trained AI/AN community health representatives (n = 8) conducted store observations (n = 96) using a checklist adapted from the Standardized Tobacco Assessment for Retail Settings observation tool. Chi-square analyses were performed to look for potential differences in availability, exterior advertising, and price promotions for cigarettes, e-cigarettes, and vapes between stores. Results. All stores sold cigarettes and over 95% sold menthol cigarettes. Nearly 25% of stores on Tribal lands were located inside a casino, and 40.4% of stores on Tribal lands offered a Tribal member discount. Stores within a 1-mile radius of Tribal lands sold significantly (p < .01) more e-cigarettes (69.8%), including flavored e-cigarettes (53.4%), compared to stores on Tribal lands (37.7% and 28.3%, respectively). Price promotions for cigarettes were significantly (p < .01) more common in stores located within a 1-mile radius of Tribal lands (46.5%) than stores on Tribal lands (22.6%). Discussion. To our knowledge, this study is the first to use store observations to examine cigarette and e-cigarette availability, advertising, and price promotions in retail settings on and near California Tribal lands. We recommend future studies build on our initial efforts to take an AI/AN Tribal community-engaged approach in assessing and documenting tobacco marketing practices on and near Tribal lands. Tribal governments can consider tobacco policies to help reduce smoking disparities and advance health equity for their communities.
Overview

Written from the paper’s full text.
TL;DR
This study used community health representatives to observe tobacco retail marketing at 96 stores on and within 1 mile of California Tribal lands. It found widespread cigarette availability and higher e-cigarette availability and cigarette price promotions in stores near Tribal lands, while Tribal member discounts were exclusive to stores on Tribal lands.
Key findings
- All stores sold cigarettes and over 95% sold menthol cigarettes; 52.1% sold e-cigarettes, 39.5% sold flavored e-cigarettes, 27% sold vape pens/vaporizers, and 25% sold flavored vape pens/vaporizers.
- Stores within a 1-mile radius of Tribal lands sold significantly more e-cigarettes (69.8%) and flavored e-cigarettes (53.4%) than stores on Tribal lands (37.7% and 28.3%, respectively; p < .01).
- Cigarette price promotions were significantly more common in stores within a 1-mile radius (46.5%) than on Tribal lands (22.6%; p < .01).
- Nearly 25% of stores on Tribal lands were located inside a casino, and Tribal member discounts were more common at retailers on Tribal lands (39.6%) than at retailers within 1 mile (0%).
Methods
- Trained AI/AN community health representatives (n = 8) conducted store observations (n = 96) using the STARS-TCT checklist adapted from STARS; data were collected October 30, 2015–February 4, 2017, on and within a 1-mile radius of California Tribal lands.
- Observations coded availability, exterior advertising, and price promotions for cigarettes, e-cigarettes, and vape pens/vaporizers; chi-square analyses tested differences between on- and near-Tribal-land stores; intercoder reliability kappa values exceeded 0.70 among 14 retailers.
- Retailers were identified from California Department of Tax and Fee Administration, Google Maps, and Esri Dun & Bradstreet data; recruitment required Tribal council/community health board permissions and Community Advisory Board guidance.
Limitations
- The paper states findings are limited to a convenience sample of retailers on or near California Tribal lands and are not generalizable to all U.S. Tribal lands due to geographic and Tribal diversity.
- The paper notes data collection took approximately 16 months (October 2015–February 2017) versus approximately 10 months for similarly sized samples in other racial/ethnic minority communities, reflecting remote geography and permission/recruitment challenges.
- Evident from the text/table: some subgroup analyses had cells with fewer than 5 and were noted as not statistically valid; the cross-sectional observational design cannot establish causal effects of marketing on tobacco use.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
