Growth of e-cigarette use among smokers has raised concerns over uptake by non-smokers, particularly young people. Legislative changes aimed in part at reducing youth exposure to e-cigarettes include the EU Tobacco Products Directive (TPD). A core justification for such measures is the belief that e-cigarettes can lead to tobacco smoking through mechanisms of renormalisation including: mimicking and normalizing the act of smoking; increasing product acceptability via marketing; nicotine exposure. These mechanisms are here explored in relation to findings from qualitative research.
This paper reports results from twenty-one group interviews with 14-15 year olds in Wales, England and Scotland, conducted as part of an ongoing evaluation of the impact of the TPD on youth smoking and e-cigarette use. Interviews were conducted around the end of the transitional period for TPD implementation, and explored perceptions of e-cigarettes and tobacco, as well as similarities and differences between them.
Young people differentiated between tobacco and e-cigarettes, rejecting the term e-cigarette in favour of alternatives such as 'vapes'. Experimental or occasional use was common and generally approved of where occurring within social activity with peers. However, regular use outside of this context was widely disapproved of, unless for the purpose of stopping smoking. Increased prevalence of e-cigarettes did not challenge strongly negative views of smoking or reduce perceived harms caused by it, with disapproval of smoking remaining high. Nicotine use was variable, with flavour a stronger driver for choice of e-liquid, and interest more generally.
The extent to which participants differentiated between vaping and smoking, including styles and reasons for use in adults and young people; absence of marketing awareness; and continued strong disapproval of smoking provides limited support for some of the potential mechanisms through which e-cigarettes may renormalise smoking. However caution over nicotine exposure is still necessary.
电子烟在吸烟者中的使用增长引起了人们对非吸烟者,尤其是年轻人使用电子烟的担忧。立法的改变旨在减少年轻人接触电子烟,其中包括欧盟烟草产品指令(TPD)。采取这些措施的核心理由是,人们相信电子烟可以通过正常化机制导致吸烟,包括模仿和正常化吸烟行为;通过营销提高产品接受度;尼古丁暴露。本文探讨了这些机制与定性研究结果的关系。
本文报告了在威尔士、英格兰和苏格兰进行的 21 组 14-15 岁青少年小组访谈的结果,这些访谈是对 TPD 对青少年吸烟和电子烟使用影响的持续评估的一部分。访谈是在 TPD 实施过渡期结束时进行的,探讨了对电子烟和烟草的看法,以及它们之间的相似之处和不同之处。
年轻人区分了烟草和电子烟,拒绝使用电子烟一词,而是更喜欢“vapes”等替代词。实验性或偶尔使用很常见,并且在与同伴进行社交活动时普遍被认可。然而,在这种情况下之外的常规使用则受到广泛的反对,除非是为了戒烟。电子烟的普及并没有挑战人们对吸烟的强烈负面看法,也没有降低人们对其造成的危害的认知,对吸烟的反对仍然很高。尼古丁的使用是可变的,口味是选择电子烟液体的更强驱动力,对电子烟的兴趣更普遍。
参与者对包括成年人和年轻人使用风格和原因在内的 vaping 和吸烟之间的区分程度;缺乏营销意识;以及对吸烟的持续强烈反对,为电子烟可能使吸烟正常化的一些潜在机制提供了有限的支持。然而,对尼古丁暴露的谨慎仍然是必要的。
