JUUL e-cigarettes are popular among youth. However, it is unknown whether adolescents understand that 5% JUUL pods contain a high nicotine concentration or consider JUULs to be e-cigarettes.
3170 students from 4 Connecticut high schools completed a school-based survey (May-October 2018). Students reported on lifetime and past-month JUUL use and perceived JUUL nicotine strength (low/medium/high/don't know) when no information about nicotine concentration was provided and, subsequently, when informed JUULs contain 5% nicotine. Students reported whether they believe JUULs are e-cigarettes (no/yes/don't know).
Students were never JUUL users (56.6%), ever users (13.2%), and past-month users (30.2%). When no information was provided, students reported that JUULs contain low (10.5%), medium (26.9%), or high nicotine levels (31.1%); 31.4% did not know. When informed JUULs contain 5% nicotine, students were more likely to believe JUUL's nicotine strength was low (29.5%) or medium (29.3%) than high (21.3%) and less likely to report not knowing (19.9%). 39% of students believed JUULs are not e-cigarettes or did not know.
Most students were unaware of JUUL's high nicotine concentration, with more believing that JUULs contain low or medium nicotine concentrations when informed JUULs contain 5% nicotine. Thus, youth may misinterpret the nicotine concentration printed on JUUL pod packaging, raising concerns about inadvertent exposure to high nicotine levels and dependence risk. Further, 39% of adolescents believed JUULs are not e-cigarettes or were unsure. Regulatory efforts are needed to establish understandable nicotine concentration labels, require products to be labeled accordingly, and clarify what products constitute e-cigarettes.
JUUL 电子烟在青少年中很受欢迎。然而，目前尚不清楚青少年是否知道 5% JUUL 烟弹含有高浓度尼古丁，或者是否认为 JUUL 是电子烟。
2018 年 5 月至 10 月，康涅狄格州 4 所高中的 3170 名学生完成了一项基于学校的调查。学生报告了终生和过去一个月使用 JUUL 的情况，并在没有提供尼古丁浓度信息的情况下报告了他们对 JUUL 尼古丁强度的看法（低/中/高/不知道），随后在得知 JUUL 含有 5%尼古丁时再次报告。学生报告他们是否认为 JUUL 是电子烟（否/是/不知道）。
从未使用过 JUUL 的学生（56.6%）、曾经使用过 JUUL 的学生（13.2%）和过去一个月使用过 JUUL 的学生（30.2%）。当没有提供信息时，学生报告说 JUUL 含有低（10.5%）、中（26.9%）或高（31.1%）尼古丁水平；31.4%的学生不知道。当得知 JUUL 含有 5%的尼古丁时，学生更有可能认为 JUUL 的尼古丁强度是低（29.5%）或中（29.3%）而不是高（21.3%），不太可能报告不知道（19.9%）。39%的学生认为 JUUL 不是电子烟或不知道。
大多数学生不知道 JUUL 的高尼古丁浓度，当得知 JUUL 含有 5%的尼古丁时，更多的学生认为 JUUL 含有低或中尼古丁浓度。因此，青少年可能会误解 JUUL 烟弹包装上印刷的尼古丁浓度，这引发了对无意中接触高尼古丁水平和依赖风险的担忧。此外，39%的青少年认为 JUUL 不是电子烟或不确定。需要开展监管工作，制定清晰易懂的尼古丁浓度标签，要求产品按规定标注，并明确哪些产品属于电子烟。
