Despite greater rates of cannabis use among those that smoke combustible cigarettes, it is currently unknown whether cannabis use is related to e-cigarette dependence or maladaptive beliefs about combustible cigarettes. Therefore, the current study sought to identify whether adult dual users of combustible and e-cigarettes (ie, dual users) who also used cannabis differed from dual users who did not use cannabis on e-cigarette dependence severity, perceived barriers to quitting, and perception of risks and of benefits of e-cigarettes.
Participants were 414 current dual users (48.3% female, M = 35.1 years, SD = 10.0), 51% of whom were current cannabis users.
Dual users who reported current cannabis use evidenced more severe dependence on e-cigarettes (η = 0.12), higher perceived barriers for quitting e-cigarettes (η = 0.06), and greater perceived benefits (η = 0.03) as well as higher perception of risks (η = 0.03) for using e-cigarettes. The results were evident after controlling for the variance associated with sex, age, education, income, and frequency of e-cigarette use.
Overall, the current findings suggest cannabis may be an important type of substance use behavior that is relevant to e-cigarette dependence and beliefs about use and quitting among adult dual users.
The present data extend current understanding of dual users by contextualizing cannabis use within e-cigarette and combustible cigarette use behaviors and highlight a potential substance use behavior that may be targetable in the framework of nicotine cessation. (Am J Addict 2020;00:00-00).
尽管吸食可燃香烟者中吸食大麻的比例更高，但目前尚不清楚大麻使用是否与电子烟依赖或对可燃香烟的不良认知有关。因此，本研究旨在确定是否吸食可燃香烟和电子烟的成年双重使用者（即双重使用者）中，那些同时使用大麻的人与那些不使用大麻的双重使用者在电子烟依赖严重程度、戒烟障碍感知、以及对电子烟风险和益处的认知上存在差异。
参与者为 414 名当前的双重使用者（48.3%为女性，M = 35.1 岁，SD = 10.0），其中 51%为当前大麻使用者。
报告当前大麻使用的双重使用者在电子烟依赖程度（η = 0.12）、戒烟电子烟障碍感知（η = 0.06）和电子烟益处感知（η = 0.03）上表现出更严重的情况，同时对电子烟使用风险的感知（η = 0.03）也更高。这些结果在控制了性别、年龄、教育程度、收入和电子烟使用频率相关的方差后仍然存在。
总的来说，目前的研究结果表明，大麻可能是一种重要的物质使用行为，与成年双重使用者的电子烟依赖和对使用和戒烟的认知有关。
本研究将大麻使用置于电子烟和可燃香烟使用行为的背景下，扩展了对双重使用者的现有理解，并强调了一种可能的物质使用行为，可能成为尼古丁戒除框架中的一个目标。
