Nicotine product use (NPU; including combustible tobacco products and/or e-cigarettes) is changing rapidly worldwide. Aiming to inform an agile policy response, this study examined NPU trends, and associations with intentions and attempts to quit tobacco.
Survey-weighted prevalences of NPU (tobacco and/or e-cigarette), tobacco, e-cigarette, and dual (tobacco and e-cigarette) use were estimated from 2015 to 2023 (excluding 2020 and 2021) using seven waves of the nationally representative Healthy Ireland survey (combined N = 52,167). Associations between sociodemographic factors and NPU, as well as between NPU and quit intentions and attempts, were examined using survey-weighted regression in the 2015 and 2023 waves.
Between 2015 and 2023, decreases in NPU were non-significant (24·6% (1846/7502) to 22·9% (1688/7356), p = 0·120), while tobacco use decreased (22·8% (1713/7502) to 17·7% (1303/7356), p = 0·012), e-cigarette use increased (3·1% (230/7502) to 8·4% (614/7356), p = 0·001) and dual use increased (1·3% (97/7502) to 3·1% (230/7356), p = 0·006). Among those aged 15-24, NPU increased from 19·6% (214/1095) in 2015 to 30·0% (345/1149) in 2023. In 2015, dual use was strongly associated with higher odds of quit intentions and attempts to quit tobacco, compared to tobacco-only, but this was no longer the case in 2023.
E-cigarette and dual use have more than doubled in Ireland, while tobacco declines have slowed. The most substantial changes occurred among 15-24-year-olds. Concurrently, the link between dual use and quit intentions and attempts attenuated. These findings underscore the need for stronger e-cigarette regulation and renewed policy efforts to achieve tobacco endgame in Ireland.

尼古丁产品使用（包括可燃烟草制品和/或电子烟）在全球范围内正在迅速变化。为了为灵活的政策应对提供信息，本研究调查了尼古丁产品使用趋势，以及与戒烟意图和尝试的关联。
使用具有全国代表性的七轮爱尔兰健康调查（总计N = 52167），估计了2015年至2023年（不包括2020年和2021年）尼古丁产品使用（烟草和/或电子烟）、烟草、电子烟以及双重使用（烟草和电子烟）的调查加权患病率。在2015年和2023年的调查中，使用调查加权回归分析了社会人口学因素与尼古丁产品使用之间的关联，以及尼古丁产品使用与戒烟意图和尝试之间的关联。
2015年至2023年期间，尼古丁产品使用的下降不显著（从24.6%（1846/7502）降至22.9%（1688/7356），p = 0.120），而烟草使用下降（从22.8%（1713/7502）降至17.7%（1303/7356），p = 0.012），电子烟使用增加（从3.1%（230/7502）增至8.4%（614/7356），p = 0.001），双重使用增加（从1.3%（97/7502）增至3.1%（230/7356），p = 0.006）。在15至24岁人群中，尼古丁产品使用从2015年的19.6%（214/1095）增至2023年的30.0%（345/1149）。2015年，与仅使用烟草相比，双重使用与更高的戒烟意图和尝试戒烟几率密切相关，但在2023年情况不再如此。
在爱尔兰，电子烟和双重使用增加了一倍多，而烟草使用的下降速度放缓。最大的变化发生在15至24岁人群中。与此同时，双重使用与戒烟意图和尝试之间的联系减弱。这些发现强调了在爱尔兰加强电子烟监管以及重新做出政策努力以实现烟草控制最终目标的必要性。
