Background: Monitoring trends and perceptions of new nicotine salt-based electronic cigarettes (ECs), like JUUL, is important to identify associations with product experimentation and use. Understanding harm perceptions of these new devices will inform prevention and intervention efforts. The current study assesses perceptions of the absolute harmfulness of JUUL use in addition to comparing it to other tobacco products. Methods: Participants (N = 839, 52% male) reporting ever use of JUUL were recruited from Amazon’s Mechanical Turk from January to March 2018. Respondents completed questionnaire items assessing demographics, co-use of non-JUUL products, JUUL use status (i.e., daily users (10.8%), non-daily users (29.4%), and triers (59.9%)), and JUUL and other tobacco products absolute harm perceptions. Results: Overall, participants rated JUUL as significantly less harmful than all other tobacco products (p < 0.001), except other ECs. Daily JUUL users rated JUUL as less harmful compared to non-daily JUUL users and JUUL triers (p < 0.05). JUUL was rated as more harmful by women compared to men (p < 0.05). Conclusions: Increased frequency of JUUL use was associated with decreased harm perceptions. JUUL was associated with reduced perceptions of absolute harm compared to most other tobacco products, except other ECs. Public health practitioners should develop public health interventions that increase harm perceptions of ECs.

曾经的用户样本中JUUL电子烟的有害感知。

背景：监测新的尼古丁盐基电子烟（EC）的趋势和感知，例如JUUL，对于确定与产品实验和使用之间的关联非常重要。了解这些新设备的危害感知将有助于预防和干预措施。目前的研究除了将其与其他烟草产品进行比较以外，还评估了对JUUL使用绝对危害的看法。方法：参与者（N= 839，报告曾使用过JUUL的男性中有52％是从2018年1月至3月从亚马逊的Mechanical Turk招募的。受访者完成了问卷调查项目，评估了人口统计数据，非JUUUL产品的共同使用，JULU的使用状态（即每日用户（10.8 ％），非每日使用者（29.4％）和试验者（59.9％））以及JUUL和其他烟草制品的绝对危害感知。结果：总体而言，参与者对JUUL的危害程度远低于所有其他烟草制品（p <0.001），其他EC除外。与非每日JUUL用户和JUUL试验者相比，每日JUUL用户对JUUL的危害较小（p <0.05）。与男性相比，女性被JUUL评为危害更大（p<0.05）。结论：使用JUUL的频率增加与伤害感知降低有关。与其他大多数烟草制品相比，除其他EC以外，JUUL与绝对危害的感知减少有关。公共卫生从业人员应制定公共卫生干预措施，以增强对EC的伤害认识。
