There is limited long-term and independent research on heated tobacco products (HTPs). We compared people who used HTPs with those who used nicotine vaping products (NVP) or cigarettes on smoker identity, indicators of effectiveness and, among NVP/HTP users, perceptions of these products.
Adults exclusive cigarette smokers (N = 45) and ex-smokers with medium/long-term (>3months) NVP (N = 46) or HTP use (N = 45) were recruited in London, UK. Participants completed a questionnaire assessing socio-demographics, smoking characteristics, smoker identity, dependence, intention to stop and attitudes towards HTP/NVP.
In adjusted analysis, people who used cigarettes (Mean Difference (MD) = 1.4, 95%Confidence Intervals (CI) 0.7,2.0) and HTPs (MD = 0.8, 95%CI 0.1, 1.5) reported stronger smoker identities than those who used NVPs. Compared with smokers, HTP/NVP users had lower cravings for cigarettes (MD = 3.0, 95%CI 1.6, 4.3; MD = 3.1, 95%CI 1.9, 4.3, respectively), and higher intention to stop product use (MD = -0.8, 95%CI -1.7,-0.01; MD = -1.2, 95%CI -2.0, -0.3, respectively). People using HTPs or NVPs reported similar perceived product satisfaction (HTP:M = 3.4, 95%CI 2.8, 3.9; NVP:M = 3.0, 95%CI 2.5, 3.5), efficacy for smoking cessation (HTP:M = 4.5, 95%CI 4.2, 4.9; NVP:M = 4.6, 95%CI 4.3, 4.9) and safety (HTP:M = 2.1, 95%CI 2.0, 2.2; NVP:M = 2.0, 95%CI 1.8, 2.1). HTP users reported greater perceived addictiveness than NVPs (MD = 0.3, 95%CI 0.2, 0.6).
HTP and NVP users perceived products to be similarly acceptable and effective suggesting that HTPs, like NVPs, may support smoking cessation. However, since HTP use appears to maintain a stronger smoker identity and perceived addiction, this may suggest a more limited role of HTP for a permanent transition away from cigarettes.
关于加热烟草制品（HTP）的长期独立研究有限。我们比较了使用 HTP 与使用尼古丁电子烟产品（NVP）或香烟的人群在烟民身份、有效性指标以及 NVP/HTP 使用者对这些产品的看法方面的差异。
在英国伦敦招募了 45 名专吸香烟的成年烟民和 46 名具有中/长期（>3 个月）NVP 或 HTP 使用史的前烟民（NVP 组和 HTP 组各 45 人）。参与者完成了一份问卷，评估了社会人口统计学特征、吸烟特征、烟民身份、依赖程度、戒烟意愿和对 HTP/NVP 的态度。
在调整分析中，使用香烟（MD=1.4，95%置信区间（CI）0.7，2.0）和 HTP（MD=0.8，95%CI 0.1，1.5）的人比使用 NVP 的人报告有更强的烟民身份认同感。与吸烟者相比，HTP/NVP 使用者对香烟的渴望程度更低（MD=-3.0，95%CI 1.6，4.3；MD=-3.1，95%CI 1.9，4.3），戒烟意愿更高（MD=-0.8，95%CI-1.7，-0.01；MD=-1.2，95%CI-2.0，-0.3）。使用 HTP 或 NVP 的人报告的产品满意度（HTP：M=3.4，95%CI 2.8，3.9；NVP：M=3.0，95%CI 2.5，3.5）和戒烟效果（HTP：M=4.5，95%CI 4.2，4.9；NVP：M=4.6，95%CI 4.3，4.9）和安全性（HTP：M=2.1，95%CI 2.0，2.2；NVP：M=2.0，95%CI 1.8，2.1）相似。HTP 用户报告的成瘾性感知高于 NVP（MD=0.3，95%CI 0.2，0.6）。
HTP 和 NVP 用户对产品的感知类似，认为它们是可接受和有效的，这表明 HTP 可能与 NVP 一样有助于戒烟。然而，由于 HTP 的使用似乎保持了更强的烟民身份认同感和感知成瘾性，这可能表明 HTP 在永久性戒烟方面的作用更为有限。
