摘要

目的:描述年轻人如何使用电子烟(电子尼古丁输送系统(ENDS))戒烟,以及他们可能成功戒烟或不成功戒烟的原因。方法:从2017年到2019年,每年收集美国加利福尼亚州25名使用ENDS戒烟/减少吸烟的年轻成年烟草使用者(18-29岁)的纵向定性数据。主题分析和轨迹分析用于确定烟草/尼古丁使用随时间变化的关键人内和人与人之间的变化。结果:在基线的香烟和ENDS双重使用者中,发现了五种类型的烟草使用转变:持续双重使用而不减少吸烟(n=8)、转变为每日仅使用ENDS(n=6)、持续双重使用并减少吸烟(n=5)、转变回纯吸烟(n=4)和转变为既不吸烟也不吸电子烟(n=2)。参与者的ENDS使用行为随着时间的推移在电子烟的数量和设备特征方面有所不同(例如,尼古丁浓度/味道的变化,在多种设备之间切换)。与用ENDS成功取代香烟有关的三个主题是感知到的积极身体效果、感知到的满足感和乐趣以及环境变化。更换不成功的四个主题是感知到的负面身体不适、感知到的成瘾和伤害、不满意的香烟替代品和设备故障。结论:年轻人使用ENDS作为戒烟辅助工具的经历是高度可变的。充足的尼古丁输送以及感知到的安全性和益处有助于成功减少或戒烟。提供行为咨询和标准化ENDS产品可能会促进年轻人戒烟。

"I'm both smoking and vaping": a longitudinal qualitative study of US young adults who tried to quit smoking cigarettes by using electronic cigarettes.

Objective: To describe how young adults use electronic cigarettes (electronic nicotine delivery systems (ENDS)) for smoking cessation and reasons why they may or may not successfully quit smoking.

Methods: Longitudinal qualitative data were collected annually from 2017 to 2019 for 25 young adult tobacco users (aged 18-29 years) in California (USA) who used ENDS to quit/reduce smoking. Thematic and trajectory analyses were used to identify key within-person and between-person changes in tobacco/nicotine use over time.

Results: Five types of tobacco use transition were identified among baseline dual users of cigarettes and ENDS: sustained dual use without reduced smoking (n=8), transition to exclusive daily ENDS use (n=6), sustained dual use with reduced smoking (n=5), transition back to exclusive smoking (n=4) and transition to neither smoking nor vaping (n=2). Participants' ENDS use behaviour varied over time in terms of vaping quantity and device characteristics (eg, changing nicotine concentrations/flavours, switching between multiple devices). Three themes that related to successfully replacing cigarettes with ENDS were perceived positive physical effects, perceived satisfaction and enjoyment and context changes. Four themes for unsuccessful replacement were perceived negative physical discomforts, perceived addictiveness and harm, unsatisfactory substitution for cigarettes and device malfunction.

Conclusions: Young adults' experiences with using ENDS as a smoking cessation aid were highly variable. Adequate nicotine delivery and perceived safety and benefits contributed to successfully reducing or quitting cigarettes. Providing behavioural counselling and standardising ENDS products may enhance cessation for young adults.
