Highlights
- Interviews with American Indian young adults in CA revealed their commercial tobacco and cannabis co-use patterns.
- Participants co-used commercial tobacco and cannabis to tailor psychoactive effects or to balance with work or caregiving.
- Co-use was also influenced by social motivations and settings that facilitate use and enhance social bonding.
Abstract
Introduction
Commercial tobacco and cannabis use in American Indian populations are disproportionately high compared to non-American Indian groups, and a nuanced understanding of patterns, contexts, and motivations for co-use of these products is needed.
Methods
American Indian young adults (N = 52, ages 21–29) in California currently using commercial tobacco and cannabis participated in a community-engaged study where they completed in-depth interviews about their commercial tobacco and cannabis use between 2023 and 2024.
Results
Participants co-used commercial tobacco and cannabis to tailor psychoactive effects (e.g., alertness from nicotine and relaxation from cannabis). Social factors influenced co-use patterns. Some participants reported using certain products like vapes or blunts to facilitate bonding in social settings. Products were commonly shared, and their use often involved taking multiple hits from the same device or product. Co-use routines also depended on participants’ responsibilities for the day, including caregiving and working, or considerations for public environments. For some, mixing commercial tobacco and cannabis was a cost-saving strategy.
Conclusions
Co-use is complex and contextual, often influenced by multiple factors, including psychoactive effects, social settings, and day-to-day responsibilities. Future interventions addressing co-use among American Indian individuals should address cravings and environmental and behavioral cues, social contexts, and promote alternative coping strategies.

Abstract
Background
American Indian (AI) youth report disproportionately high e-cigarette use (16%), twice that of Non-Hispanic White youth (8%). However, culturally tailored vaping prevention interventions remain. Preliminary findings from the pilot assessment of Vaping Endgame (VE), an AI culturally adapted vaping prevention curriculum developed through a community-informed process, highlights pre–post outcomes, participant acceptability, and satisfaction.
Methods
Using Community-Based Participatory Research and Positive Youth Development principles, the VE curriculum was adapted from the Intervention for Nicotine Dependence: Education, Prevention, Tobacco, and Health and included Medicine Wheel elements. AI students participated in the 5-day VE program. Pre–post assessment included knowledge, attitudes, perceived behavioral control, intentions toward e-cigarette use, and readiness to change vaping behaviors. Feedback from participants and Youth Advocate Team (YAT) members assessed acceptability and satisfaction of the curriculum.
Results
Of 63 eligible AI students (7–12 grade), 32 participated in the VE pilot intervention (50.8% participation; 100% retention). Participants had a significant increase in knowledge of vaping harms (100% vs. 88%), commercial tobacco marketing tactics toward youth (94% vs. 97%), and ceremonial tobacco use (6% vs. 16%). Their perceived behavioral control against vaping significantly increased (r = −0.50, P < .001). Students rated the curriculum and facilitator (average 8.8/10). YAT members described pride contributing to the VE program.
Conclusion
Preliminary outcomes showed changes in knowledge and perceived behavioral control of vaping, and high satisfaction of the VE program. To our knowledge, this is the first culturally responsive vaping curriculum developed and assessed for AI youth, suggesting potential for broader delivery.
