PURPOSE
The aim of the study was to describe young adult use and perceptions of different brands of pod-based electronic cigarettes (e-cigarettes) and compare with earlier types of non-pod-based e-cigarettes (e.g., mods and tanks).
METHODS
Data were collected from January to March 2019 and derive from the final wave of a cohort study recruited in 2013-2014 using a convenience sample from 10 large California high schools with racially/ethnically and socioeconomically diverse populations. A total of 445 participants completed an online survey (mean age = 20.1 years [SD = 1.66], 64.8% female [n = 278], 38.8% white [n = 161], 23.9% each for Asian and "more than one race" [n = 99], 13.5% other [n = 56], and 36.9% Hispanic [n = 160]). The main outcomes were description of and reasons to use pods, perceived nicotine content, and use patterns.
RESULTS
Although <25% of participants reported smoking cigarettes and using non-pod-based e-cigarettes, >25% reported ever use of JUUL. Similarly, <33% of cigarette smokers and non-pod-based e-cigarette users reported use in the past 30 days, and >50% of JUUL ever users did. The most agreed upon reason (58%) for using pods was because they are "easy to hide." About half of pod users "do not know" if they mix brands of e-juice and pods, the nicotine concentration in their e-juice cartridges, nor time to finish a cartridge. Of the 50% of participants who shared their pod, 23 (15%) did "sometimes," 20 (13%) "always," and 16 (11% each) "about half the time" or "often." There was no consensus about how to refer to different brands of pods.
CONCLUSIONS
Our findings indicate young adults harbor confusion about pod-based e-cigarettes, including nicotine content, usage patterns, and labeling, and that pod use is largely because of the ease with which they can "stealth" vape. The findings suggest needed regulation and education about these products.
目的
本研究旨在描述年轻成年人使用不同品牌 pod 型电子烟（电子烟）的情况和认知，并与早期的非 pod 型电子烟（如 mod 和 tank）进行比较。
方法
数据收集于 2019 年 1 月至 3 月，来源于 2013-2014 年一项队列研究的最后一波调查，该研究采用便利抽样从加利福尼亚州 10 所大型高中招募参与者，这些高中的人群在种族/民族和社会经济方面具有多样性。共有 445 名参与者完成了一项在线调查（平均年龄 20.1 岁[SD=1.66]，64.8%为女性[n=278]，38.8%为白人[n=161]，各有 23.9%为亚裔和“多于一个种族”[n=99]，13.5%为其他[n=56]，36.9%为西班牙裔[n=160]）。主要结果是描述和使用 pod 的原因、感知尼古丁含量和使用模式。
结果
尽管<25%的参与者报告吸烟和使用非 pod 型电子烟，但>25%的参与者报告曾使用过 JUUL。同样，<33%的香烟吸烟者和非 pod 型电子烟使用者报告在过去 30 天内使用过，而>50%的 JUUL 曾使用者有过使用。使用 pod 的最主要原因（58%）是因为它们“易于隐藏”。大约一半的 pod 用户“不知道”他们是否混合使用不同品牌的电子烟烟油和 pod，也不知道他们电子烟烟油盒中的尼古丁浓度，以及用完一个烟油盒所需的时间。在分享 pod 的 50%参与者中，23（15%）人“有时”分享，20（13%）人“总是”分享，16（11%）人“大约一半时间”或“经常”分享。对于不同品牌的 pod，参与者没有达成共识如何称呼它们。
结论
我们的研究结果表明，年轻成年人对 pod 型电子烟存在困惑，包括尼古丁含量、使用模式和标签，而且他们使用 pod 主要是因为可以“偷偷”吸电子烟。研究结果表明，需要对这些产品进行监管和教育。
