Passive exposure to combustible cigarette use has been shown to act as a cue to increase smoking urge. Given the resemblance of e-cigarettes and other electronic nicotine delivery systems (ENDS) to combustible cigarettes, we examined whether these devices could also act as a cue to increase smoking desire and urges in those passively exposed.
Young adult daily smokers (age 18-35 years; N=60) completed subjective ratings before and after exposure to a study confederate drinking bottled water (control cue) and then smoking either a combustible or e-cigarette (active cue). Smoking desire and urge ratings were measured with visual analogue scale items for desire for a regular and an e-cigarette and the Brief Questionnaire of Smoking Urges.
Passive exposure to both the e-cigarette and combustible cigarette cue significantly increased observers' ratings of desire and urge to smoke a regular cigarette (all ps<0.05). Exposure to the e-cigarette cue but not the regular cigarette cue also increased desire to smoke an e-cigarette (p<0.01).
The results provide the first evidence in a controlled setting that electronic cigarette exposure may evoke smoking urges in young adult daily smokers. With replication, these findings may have relevance for ENDS regulation and policy.
被动接触可燃香烟已被证明是增加吸烟欲望的一个诱因。鉴于电子烟和其他电子尼古丁传送系统（ENDS）与可燃香烟相似，我们研究了这些装置是否也能成为增加被动接触者吸烟欲望和冲动的诱因。
成年日常吸烟者（年龄18 - 35岁；N = 60）在接触一名研究助手喝瓶装水（对照诱因）以及随后吸一支可燃香烟或电子烟（主动诱因）之前和之后完成主观评分。吸烟欲望和冲动评分通过视觉模拟量表项目来测量，这些项目涉及对普通香烟和电子烟的渴望以及简短吸烟冲动问卷。
被动接触电子烟和可燃香烟诱因均显著提高了观察者对吸普通香烟的欲望和冲动评分（所有p值<0.05）。接触电子烟诱因而非普通香烟诱因也增加了吸电子烟的欲望（p<0.01）。
研究结果首次在可控环境中证明，接触电子烟可能会唤起成年日常吸烟者的吸烟冲动。若能重复验证，这些发现可能与ENDS的监管和政策相关。
