Youth nicotine dependence may vary by e-cigarette device used.
E-cigarette device type ("JUUL," "similar pod/JUUL like device (i.e., pod mod)," or "other type of e-cigarette" (i.e., tank, mod)), nicotine dependence (Hooked on Nicotine Checklist; HONC), frequency of e-cigarette use (i.e., weekly, daily, monthly), and covariates were examined via a convenience sample of youth who use e-cigarettes in the United States via an online Qualtrics panel survey from April 2019 to May 2019.
Youth aged 13-17 (Mean age = 15.9 years, SD = 1.0 year; n = 185) were mostly 72.4% female. Primary device used by category was endorsed as follows: JUUL n = 87, pod mod n = 42, and other type of e-cigarette n = 56. Participants endorsed an average of 4.5 / 10 HONC symptoms (SD = 3.6). Compared to other e-cigarettes, youth who used JUUL and pod mod devices endorsed more dependence symptoms, even when adjusting for current smoking status (JUUL IRR = 1.96, 95% CI 1.30-2.97; pod mod device IRR = 1.76, 95% CI 1.08-2.87). In total, HONC symptoms significantly differed by device for 8/10 symptoms, with JUUL and pod mod users reporting higher frequency of items compared to other e-cigarette devices.
Features of nicotine dependence experienced by youth (i.e., feeling a stronger urge to vape) differed by primary device used, with those using JUUL and pod-mods reporting a greater level of dependence. Regulation of features of e-cigarette devices that may increase nicotine delivery and subsequent development of dependence among youth warrant urgent consideration.
青少年对尼古丁的依赖可能因使用的电子烟装置而异。
通过美国在线 Qualtrics 小组调查，对使用电子烟的青少年进行便利抽样，调查电子烟装置类型（“JUUL”、“类似烟弹/JUUL 类似装置（即烟弹装置）”或“其他类型电子烟”（即罐式、模块式）”）、尼古丁依赖（尼古丁依赖检查表；HONC）、电子烟使用频率（即每周、每天、每月）和协变量。
年龄在 13-17 岁之间的青少年（平均年龄 15.9 岁，标准差 1.0 岁；n=185）中，女性占 72.4%。按类别使用的主要装置如下：JUUL n=87、pod mod n=42、其他类型电子烟 n=56。参与者平均报告了 4.5/10 个 HONC 症状（标准差 3.6）。与其他电子烟相比，使用 JUUL 和 pod mod 装置的青少年报告的依赖症状更多，即使调整了当前吸烟状况（JUUL 的 IRR=1.96，95%置信区间 1.30-2.97；pod mod 装置的 IRR=1.76，95%置信区间 1.08-2.87）。总共有 8/10 个症状的 HONC 症状因装置而异，与其他电子烟装置相比，使用 JUUL 和 pod mod 的用户报告的项目频率更高。
青少年经历的尼古丁依赖特征因主要使用的装置而异，使用 JUUL 和 pod-mod 的青少年报告的依赖程度更高。急需考虑对电子烟装置的特征进行监管，这些特征可能会增加尼古丁的输送，并随后导致青少年对尼古丁的依赖。
