Introduction

Youth nicotine dependence may vary by e-cigarette device used.

Methods

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.

Results

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.

Conclusions

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.

青少年使用电子烟：依赖是否因设备类型而异？

介绍

青少年尼古丁依赖可能因使用的电子烟设备而异。

方法

电子烟设备类型（“JUUL”、“类似烟弹/类似烟弹的设备（即烟弹 mod）”或“其他类型的电子烟”（即罐、烟弹））、尼古丁依赖（Hooked on Nicotine Checklist ; HONC)、电子烟使用频率（即每周、每天、每月）和协变量通过 2019 年 4 月至 5 月的在线 Qualtrics 小组调查在美国使用电子烟的青年的便利样本进行了检查2019 年。

结果

13-17 岁的青年（平均年龄 = 15.9 岁，SD = 1.0 岁；n  = 185）大部分是 72.4% 的女性。按类别使用的主要设备被认可如下：JUUL n  = 87，pod mod n  = 42，和其他类型的电子烟n  = 56。参与者认可平均 4.5 / 10 HONC 症状（SD  = 3.6）。与其他电子烟相比，使用 JUUL 和 pod mod 设备的青少年认可更多的依赖症状，即使在调整当前吸烟状态时也是如此（JUUL IRR = 1.96, 95% CI 1.30–2.97; pod mod device IRR = 1.76, 95% CI 1.08-2.87)。总体而言，HONC 症状因 8/10 症状的设备而异，与其他电子烟设备相比，JUUL 和 pod mod 用户报告的物品频率更高。

结论

青少年经历的尼古丁依赖特征（即，感到更强烈的电子烟冲动）因使用的主要设备而异，使用 JUUL 和 pod-mods 的人报告的依赖程度更高。需要紧急考虑对可能增加尼古丁输送和随后发展青年依赖的电子烟设备的功能进行监管。
