Abstract

Background

Understanding the motivational processes that influence e-cigarette use in a laboratory setting may help elucidate mechanisms that support long-term ecigarette use, which could have significant clinical and public health consequences.

Methods

Secondary analyses were conducted on data from exclusive smokers (N=47) and dual users (N=88) who underwent a laboratory ad lib use session. Participants were given 10 minutes to smoke (exclusive smokers) or vape (dual users) as much as they wanted. Withdrawal was assessed pre- and post-use. Smoking and vaping behavior was coded from session videos. Person-level predictors included cigarette/ecigarette craving-relief expectancies, demographics, and cigarette/e-cigarette use and dependence. Smoking and vaping status was assessed at Year 1 using self-reported 30-day point prevalence. Data were analyzed using general linear models and logistic regressions.

Results

Both groups reported reductions in withdrawal after product use, including cigarette craving. Baseline e-cigarette craving-relief expectancies, pre-session ecigarette craving, heaviness of e-cigarette use, and relative e-cigarette dependence were significant univariate predictors of continued vaping in dual users at Year 1 (ORs>1.04, ps<.05). Dual users and exclusive smokers did not differ on use behavior (i.e., average number of puffs, ps>.16).

Conclusions

E-cigarette use alleviated withdrawal, including cigarette and e-cigarette craving, in dual users. Laboratory use behavior did not differ between dual users using e-cigarettes and exclusive smokers using cigarettes. Greater e-cigarette craving-relief expectancies, e-cigarette craving, heaviness of e-cigarette use, and morning product use pattern (‘relative dependence’) may reflect mechanisms that sustain e-cigarette use.

了解双重吸烟者和专门吸烟者吸烟和吸食电子烟的动机机制
背景了解在实验室环境中影响电子烟使用的动机过程可能有助于阐明支持长期使用电子烟的机制,这可能会对临床和公共健康产生重大影响。方法对接受实验室自由使用环节的专属吸烟者(N=47)和双重使用者(N=88)的数据进行了二次分析。参与者有10分钟的时间随意吸烟(完全吸烟者)或吸食毒品(双重使用者)。对使用前和使用后的戒断情况进行了评估。吸烟和吸食电子烟的行为是通过会话视频进行编码的。个人层面的预测因素包括香烟/电子烟渴望-缓解期望、人口统计学、香烟/电子烟使用和依赖。在第一年,使用自我报告的 30 天点流行率评估吸烟和吸电子烟状况。使用一般线性模型和逻辑回归对数据进行了分析。基线电子烟渴求缓解预期、会前电子烟渴求、电子烟使用强度和电子烟相对依赖性是双重使用者在第一年继续吸食电子烟的重要单变量预测因素(ORs>1.04, ps<.05)。结论使用电子烟可减轻双重使用者的戒断症状,包括对香烟和电子烟的渴求。使用电子烟的双重使用者与使用香烟的纯吸烟者在实验室使用行为上没有差异。更大的电子烟渴求缓解预期、电子烟渴求、电子烟使用强度和上午产品使用模式("相对依赖")可能反映了维持电子烟使用的机制。

期刊介绍: Drug and Alcohol Dependence is an international journal devoted to publishing original research, scholarly reviews, commentaries, and policy analyses in the area of drug, alcohol and tobacco use and dependence. Articles range from studies of the chemistry of substances of abuse, their actions at molecular and cellular sites, in vitro and in vivo investigations of their biochemical, pharmacological and behavioural actions, laboratory-based and clinical research in humans, substance abuse treatment and prevention research, and studies employing methods from epidemiology, sociology, and economics.
