PURPOSE
Although existing evidence indicates that e-cigarette use is a risk factor for cigarette smoking initiation, mechanisms of this association are not yet known. E-cigarette users perceive e-cigarette use to be less harmful relative to conventional cigarettes, but their absolute perceptions of addictiveness of conventional cigarette smoking are unknown. This study examines how e-cigarette users compare with nonusers (non-e-cigarette users/nonconventional cigarette smokers), conventional cigarette smokers, and dual users on perceptions of harm and the addictiveness of conventional cigarette smoking and on other known predictors of cigarette smoking such as peer smoking, influence of antismoking ads, and risk-taking propensity.
METHODS
National samples of 8th- and 10th-grade students from 2014 and 2015 (N = 14,151) were obtained from the Monitoring the Future Study. Multivariate logistic regression models were used to examine relationships between adolescent smoking status and perceptions of harm and the addictiveness of conventional cigarette smoking while controlling for potential confounders.
RESULTS
E-cigarette users had lower perceptions of the addictiveness of conventional cigarette smoking compared with nonusers but higher than cigarette smokers and dual users. E-cigarette users reported lower influence by antismoking ads, more conventional cigarette-smoking peers, and greater risk-taking propensity than nonusers. E-cigarette users and cigarette smokers did not differ in their perceived harm of conventional cigarette smoking or in their risk-taking propensity.
CONCLUSIONS
E-cigarette users' attitudes and perceptions regarding conventional cigarette smoking may leave them vulnerable to becoming conventional cigarette smokers. Future studies should explore the prospective relationship between smoking-related perceptions of conventional cigarette smoking among e-cigarette users and the onset of cigarette smoking.
目的
尽管现有证据表明电子烟的使用是开始吸烟的一个风险因素，但这种关联的机制尚不清楚。电子烟使用者认为电子烟相对于传统香烟的危害较小，但他们对传统香烟成瘾性的绝对认知尚不清楚。本研究考察了电子烟使用者与非使用者（非电子烟使用者/非传统香烟吸烟者）、传统香烟吸烟者和双重使用者在对传统香烟危害和成瘾性的看法上有何不同，以及在其他已知的吸烟预测因素（如同伴吸烟、反吸烟广告的影响和冒险倾向）上有何不同。
方法
本研究从 2014 年和 2015 年的“监测未来研究”中获得了来自八年级和十年级学生的全国样本（N=14151）。采用多变量逻辑回归模型，在控制潜在混杂因素的情况下，考察了青少年吸烟状况与对传统香烟危害和成瘾性的看法之间的关系。
结果
与非使用者相比，电子烟使用者对传统香烟成瘾性的看法较低，但高于香烟吸烟者和双重使用者。电子烟使用者报告说，反吸烟广告对他们的影响较小，吸传统香烟的同伴较多，冒险倾向较大。电子烟使用者和香烟吸烟者在对传统香烟危害的看法或冒险倾向方面没有差异。
结论
电子烟使用者对传统香烟的态度和看法可能使他们容易成为传统香烟吸烟者。未来的研究应该探讨电子烟使用者与传统香烟相关的吸烟看法与开始吸烟之间的前瞻性关系。
