E-cigarettes, the most popular tobacco product among adolescents, vary widely in design and nicotine composition; thus, different devices may have different addictive potential. However, few studies examine levels of nicotine dependence across devices among adolescent and young adult (AYA) e-cigarette users. To assess the extent of nicotine dependence among US AYA (ages 13-24) by e-cigarette device type, we conducted a large, national, cross-sectional survey ( = 4351) and used the Hooked on Nicotine Checklist (HONC) to assess levels of nicotine dependence among those who had used disposable, pod-based, and/or mods/other e-cigarette devices in the past 30 days. We also examined HONC scores among those who had used combustible cigarettes in the past 30 days, whether with or without using e-cigarettes. Patterns of nicotine dependence were comparable across those who had used a combustible cigarette and/or e-cigarette in the past 30 days, with 91.4% of combustible cigarette users, 80.7% of disposable e-cigarette users, 83.1% of pod-based e-cigarette users, and 82.5% of mods/other e-cigarette users showing signs of nicotine dependence, as measured by endorsing at least one HONC symptom. This pattern persisted when analyses were restricted to e-cigarette only users, with more than 70% of all e-cigarette only past-30-day users endorsing at least one HONC symptom, across all types of devices. A thorough understanding of the extent and presentation of nicotine dependence among AYA will help researchers, public health officials, and clinicians recognize and manage AYA nicotine dependence.
电子烟是青少年最受欢迎的烟草产品之一，在设计和尼古丁成分上差异很大；因此，不同的设备可能具有不同的成瘾潜力。然而，很少有研究调查青少年和年轻成年人（AYA）电子烟使用者中不同设备之间的尼古丁依赖程度。为了评估美国 AYA（13-24 岁）电子烟设备类型的尼古丁依赖程度，我们进行了一项大型的全国性横断面调查（n=4351），并使用尼古丁依赖程度检查表（HONC）评估了过去 30 天内使用过一次性、pod 型和/或 mods/其他电子烟设备的人群的尼古丁依赖程度。我们还检查了过去 30 天内使用过可燃香烟（无论是否同时使用电子烟）的人群中的 HONC 评分。在过去 30 天内使用过可燃香烟和/或电子烟的人群中，尼古丁依赖模式相似，使用可燃香烟的人群中有 91.4%、一次性电子烟使用者中有 80.7%、pod 型电子烟使用者中有 83.1%、mods/其他电子烟使用者中有 82.5%出现尼古丁依赖迹象，这是通过至少一个 HONC 症状来衡量的。当分析仅限于仅使用电子烟的人群时，这种模式仍然存在，所有类型设备中，超过 70%的所有过去 30 天仅使用电子烟的人群都至少认可了一个 HONC 症状。全面了解 AYA 尼古丁依赖的程度和表现将有助于研究人员、公共卫生官员和临床医生识别和管理 AYA 尼古丁依赖。
