In this study, we assessed complete switching away from cigarette smoking among adult smokers who purchased a JUUL Starter Kit (JSK). Adult (age ≥ 21) established smokers (smoked ≥ 100 lifetime cigarettes) who purchased a JSK in 2018 were invited to complete online surveys 1, 2, 3, 6, 9 and 12 months after initial JSK purchase. Point prevalence of switching (no past 30-day smoking) was assessed at each follow-up. Repeated measures logistic regression models evaluated associations of sociodemographic factors, baseline smoking characteristics and time-varying JUUL System ("JUUL") use characteristics and switching across the 12-month period. Respondents (N = 17,986) were 55.0% male, 78.3% white, mean age = 32.65 years (SD = 10.81), mean baseline cigarettes/day = 11.10 (SD = 8.16). The proportion self-reporting switching increased over time: one-month (27.2%[3718/13,650]), 2-month (36.4%[4926/13,533]), 3-month (41.0%[5434/13,257]), 6-month (46.6%[5411/11,621]), 9-month (49.4%[6017/12,186]), and 12-month (51.2%[6106/11,919]); 33.1% reported switching at both 9-month and 12-month follow-ups. In prospective analyses, smokers with lower cigarette dependence, shorter smoking history, lower cigarette consumption, more frequent JUUL use, greater satisfaction from initial JUUL use, and higher JUUL dependence were significantly more likely to switch. Rates of switching with JUUL increased over time. Over 50% of respondents reported complete switching away from cigarettes 12 months following purchase. Greater use of and dependence on JUUL predicted switching.
在这项研究中，我们评估了购买 JUUL 入门套件（JSK）的成年吸烟者完全戒烟的情况。 2018 年购买 JSK 的成年（年龄≥21 岁）已建立的吸烟者（吸烟≥100 支终生香烟）被邀请在初始 JSK 购买后 1、2、3、6、9 和 12 个月完成在线调查。在每次随访时评估过去 30 天吸烟的点患病率。重复测量逻辑回归模型评估了社会人口统计学因素、基线吸烟特征以及随时间变化的 JUUL 系统（“JUUL”）使用特征与 12 个月期间戒烟的关联。 受访者（N=17986）中，55.0%为男性，78.3%为白人，平均年龄为 32.65 岁（SD=10.81），平均基线每天吸烟量为 11.10 支（SD=8.16）。自我报告戒烟的比例随着时间的推移而增加：一个月（27.2%[3718/13650]），两个月（36.4%[4926/13533]），三个月（41.0%[5434/13257]），六个月（46.6%[5411/11621]），九个月（49.4%[6017/12186]），十二个月（51.2%[6106/11919]）；33.1%的人在 9 个月和 12 个月的随访中都报告了戒烟。在前瞻性分析中，吸烟依赖性较低、吸烟史较短、吸烟量较少、更频繁使用 JUUL、初始 JUUL 使用满意度较高以及 JUUL 依赖性较高的吸烟者戒烟的可能性更大。随着时间的推移，使用 JUUL 戒烟的比例增加。超过 50%的受访者报告在购买 JUUL 后的 12 个月内完全戒烟。对 JUUL 的使用更多和依赖性更高预测了戒烟。
