E-cigarettes are the most popular aid to smoking cessation attempts in England and the USA. This research examined associations between e-cigarette device characteristics and patterns of use, tobacco-smoking relapse, and smoking abstinence.
A convenience sample of 371 participants with experience of vaping, and tobacco-smoking abstinence and/or relapse completed an online cross-sectional survey about e-cigarettes. Factors associated with smoking relapse were examined using multiple linear and logistic regression models.
Most participants were self-reported long-term abstinent smokers (86.3%) intending to continue vaping. Most initiated e-cigarette use with a vape pen (45.8%) or cig-a-like (38.7%) before moving onto a tank device (89%). Due to missing data, managed through pairwise deletion, only around 70 participants were included in some of the main analyses. Those using a tank or vape pen appeared less likely to relapse than those using a cig-a-like (tank vs. cig-a-like OR = 0.06, 95% CI 0.01-0.64, p = 0.019). There was an inverse association between starting self-reported e-cigarette liquid nicotine concentration and relapse, interacting with device type (OR = 0.79, 95% CI 0.63-0.99, p = 0.047), suggesting that risk of relapse may have been greater if starting with a low e-cigarette liquid nicotine concentration and/or cig-a-like device. Participants reported moving from tobacco-flavored cig-a-likes to fruit/sweet/food flavors with tank devices.
Knowledge of how people have successfully maintained tobacco-smoking abstinence using vaping could help other tobacco smokers wishing to quit tobacco smoking through vaping.
电子烟是英国和美国最受欢迎的戒烟辅助工具。本研究调查了电子烟设备特性和使用模式与吸烟复发和戒烟之间的关联。
一项关于电子烟的在线横断面调查，共纳入 371 名有电子烟使用经验且已戒烟和/或复吸的参与者。使用多元线性和逻辑回归模型来检验与吸烟复发相关的因素。
大多数参与者是自我报告的长期戒烟吸烟者（86.3%），打算继续使用电子烟。大多数参与者最初使用笔型电子烟（45.8%）或雪茄型电子烟（38.7%），然后再使用罐式设备（89%）。由于数据缺失，通过成对删除进行了处理，只有大约 70 名参与者被纳入了一些主要分析中。与使用雪茄型电子烟相比，使用罐式或笔型电子烟的人复发的可能性较小（罐式 vs. 雪茄型 OR=0.06，95%CI 0.01-0.64，p=0.019）。开始使用自我报告的电子烟液体尼古丁浓度与复发呈负相关，且与设备类型存在交互作用（OR=0.79，95%CI 0.63-0.99，p=0.047），这表明如果开始时使用低浓度电子烟液体尼古丁和/或雪茄型电子烟，复发的风险可能更大。参与者报告说从烟草味的雪茄型电子烟转向使用罐式设备的水果/甜味/食品味电子烟。
了解人们如何通过电子烟成功保持吸烟戒断，可能有助于其他希望通过电子烟戒烟的吸烟者。
