Nine programs implemented smoke-free household efforts with mixed but generally positive uptake of voluntary pledges. Five programs implemented tobacco product waste initiatives that increased awareness of environmental harms and mobilized community clean-up events, and four pursued excise tax strategies, with questions about revenue allocation emerging as a key challenge. Across objectives, culturally relevant, community-driven approaches were seen as critical to success.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Tribal-led interventions including youth coalitions, smoke-free household pledges, and tobacco waste campaigns show promise for reducing commercial tobacco harms in California American Indian communities, though policy and implementation barriers remain and warrant ongoing attention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Implications<\/jats:title>\n                    <jats:p>This study adds to the limited body of research evaluating culturally grounded tobacco control interventions in American Indian communities. By highlighting the relative success of youth engagement, smoke-free household pledges, and community-based environmental initiatives, the findings underscore the importance of culturally relevant, community-driven approaches. These results can inform future Tribal, state, and federal tobacco prevention strategies, reinforcing the need to integrate Indigenous values, leadership, and local context into public health programming to improve intervention reach and sustainability.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ntr\/ntag105","type":"journal-article","created":{"date-parts":[[2026,5,12]],"date-time":"2026-05-12T11:29:04Z","timestamp":1778585344000},"page":"1548-1554","source":"Crossref","is-referenced-by-count":0,"title":["Success and challenges of tobacco control interventions among American Indians in California"],"prefix":"10.1093","volume":"28","author":[{"given":"Ana Liujia Peng","family":"Zhao","sequence":"first","affiliation":[{"name":"Herbert Wertheim School of Public Health and Human Longevity Science, University of California San Diego , La Jolla, CA 92093 ,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chadwick K","family":"Campbell","sequence":"additional","affiliation":[{"name":"Herbert Wertheim School of Public Health and Human Longevity Science, University of California San Diego , La Jolla, CA 92093 ,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Becky","family":"Marquez","sequence":"additional","affiliation":[{"name":"Herbert Wertheim School of Public Health and Human Longevity Science, University of California San Diego , La Jolla, CA 92093 ,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8292-0510","authenticated-orcid":false,"given":"Wael K","family":"Al-Delaimy","sequence":"additional","affiliation":[{"name":"Herbert Wertheim School of Public Health and Human Longevity Science, University of California San Diego , La Jolla, CA 92093 ,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,5,14]]},"reference":[{"key":"2026082400121218100_ref1","doi-asserted-by":"publisher","first-page":"E45","DOI":"10.5888\/pcd20.220375","article-title":"US cigarette smoking disparities by race and ethnicity - keep going and going!","volume":"20","author":"Arrazola","year":"2023","journal-title":"Prev Chronic Dis"},{"key":"2026082400121218100_ref2","volume-title":"California Tobacco Facts and Figures 2022","author":"California Department of Public Health","year":"2023"},{"key":"2026082400121218100_ref3","article-title":"American Indian and Alaska native people need more protection from exposure to secondhand smoke","author":"Centers for Disease Control and Prevention","year":"2024"},{"key":"2026082400121218100_ref4","article-title":"American Indian and Alaska native people experience a health burden from commercial tobacco","author":"Centers for Disease Control and Prevention","year":"2024"},{"key":"2026082400121218100_ref5","article-title":"Lung cancer risk factors: smoking and lung cancer.
