Most people who smoke cigarettes begin young. Consequently, public health efforts directed at youth are a priority. The increasing popularity of electronic nicotine delivery systems (ENDS) among youth in the United States has raised concerns in the public health community about the potential of ENDS to renormalize cigarette smoking and perpetuate nicotine addiction, creating dual users who both vape and smoke. Despite limited and inconclusive evidence about dual use for young people, restrictive approaches towards ENDS have shaped tobacco control agendas in the United States. Based on analysis of 26 interviews with young dual users in California, we explored the meanings young people ascribe to their dual using practices and how those meanings relate to the broader tobacco control environment which structures their lives. Results suggest that dual users of ENDS and cigarettes overwhelmingly perceive a utilitarian meaning of dual use and view vaping as a tool for reducing smoking-related harm in the near term and facilitating quitting smoking in the long term. Also, participants' narratives related to Tobacco 21 laws, which prohibit sales of both ENDS and cigarettes to individuals under 21 years of age, revealed concerns about restrictive policies that limit access to less harmful tobacco products. Results of this study raise important questions about whether we are working towards further reductions in the prevalence of smoking and tobacco-related diseases.
大多数吸烟的人都是从年轻时开始的。因此，针对年轻人的公共卫生工作是当务之急。在美国，年轻人越来越喜欢使用电子尼古丁输送系统（ENDS），这引起了公共卫生界的关注，担心 ENDS 会使吸烟行为正常化，使尼古丁成瘾永久化，导致双重使用者既吸电子烟又吸香烟。尽管关于年轻人双重使用的证据有限且不明确，但对 ENDS 的限制措施已经影响了美国的烟草控制议程。本研究基于对加利福尼亚州 26 名年轻双重使用者的访谈分析，探讨了年轻人对其双重使用行为的看法，以及这些看法与塑造他们生活的更广泛的烟草控制环境之间的关系。结果表明，电子烟和香烟的双重使用者普遍认为双重使用具有功利意义，他们将吸电子烟视为减少吸烟相关危害的短期工具，并长期促进戒烟。此外，参与者对禁止向 21 岁以下个人销售电子烟和香烟的 21 岁烟草法案的叙述，也揭示了对限制获取危害较小的烟草产品的政策的担忧。本研究结果提出了一些重要问题，即我们是否在努力进一步降低吸烟和与烟草相关疾病的流行率。
