{"doi":"10.1111/josh.70077","title":"Student and Staff Knowledge of School Tobacco Policies and Student E‐Cigarette Use, California 2022–2023","abstract":"BACKGROUND: Since 2016, California has prohibited e-cigarette use alongside smoking in K-12 schools. School tobacco policies may reduce student e-cigarette use. METHODS: We analyzed 2022 to 2023 California Healthy Kids Survey (CHKS) and School Staff Survey data (n = 219,114). Multivariable logistic regression was used to examine associations between student and staff awareness of school tobacco policies and current e-cigarette use, adjusting for demographics. RESULTS: Among students, 5.2% reported current e-cigarette use; 69.6% knew of a school policy. Most staff knew the policy (91.2%), but fewer endorsed consistent enforcement (88.2%) or prevention education (61.7%). Compared to students reporting no policy, those aware of one (OR = 0.54, p < 0.0001) or unsure (OR = 0.40, p < 0.0001) had lower use. Higher staff knowledge was associated with increased use (OR = 1.2, p = 0.0199), while enforcement agreement was associated with lower use (OR = 0.81, p = 0.0019). CONCLUSIONS: Student knowledge and staff perceptions of policy enforcement were associated with lower e-cigarette use. Findings suggest that consistent enforcement and school-wide communication, not just policy presence, are essential for impact. IMPLICATIONS: Improving policy visibility and staff training on enforcement may strengthen school policies and reduce tobacco use.","journal":"Journal of School Health","year":2025,"id":536646,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9512,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":431794,"name":"Susan L.
