Introduction To identify intervention priorities for reducing tobacco use among youth in Heilongjiang, this study examined provincial epidemiological patterns of cigarette and e-cigarette adoption from 2014 to 2023, providing evidence-based foundations for timely provincial school tobacco control strategies. Methods School-based cross-sectional surveys were conducted in 2014, 2019, 2021 and 2023. A randomized multistage stratified cluster sampling design was employed to obtain representative samples of middle school students (MSs) and high school students (HSs). Results In 2019, 2021 and 2023, the current cigarette and e-cigarette use rates among MSs and HSs were 6.79%, 5.45%, and 4.70%, and 3.61%, 5.46%, and 2.07%, respectively. The current dual-use rates for cigarettes and e-cigarettes were 1.74%, 2.83%, and 1.03%, respectively. The current rates for either cigarette or e-cigarette use were 8.70%, 8.10%, and 5.76%, respectively. Among current cigarette users of MSs and HSs, the rates of e-cigarette use first were 15.59%, 12.75%, and 21.80%, respectively. Among cigarette and e-cigarette dual-users of MSs and HSs, the rates of e-cigarette use first were 17.46%, 14.99%, and 28.41%, respectively. Conclusions From 2014 to 2023, based on results from four province-wide surveys, cigarette use rates among MSs and HSs in Heilongjiang declined, while e-cigarette use rates showed a peak in 2021 before decreasing. Policies such as "smoke-free schools" and e-cigarette regulation were beginning to show results. Joint efforts between families and schools, as well as collaboration among multiple departments were essential to ensure effective implementation of tobacco control measures and would be the focus of future tobacco control work.
