Electronic cigarettes (e-cigarettes) have become increasingly popular in recent years. Existing evidence indicates e-cigarettes used in isolation are less harmful than combustible cigarettes, yet emerging work has demonstrated that adults use e-cigarettes largely in combination with combustible cigarettes (i.e. dual use). Despite this data, little is understood about how exclusive and dual e-cigarette users may differ across behavioral outcomes, such as substance use dependence and behaviors among adults.
Thus, the current project examined differences in e-cigarette dependence, problematic alcohol use, cannabis use, and nonmedical prescription opioid use (e.g. methadone and oxycodone) across both exclusive and dual e-cigarette adult users.
Participants included 531 (53.6% female; M = 35.29years, SD = 10.44) adults with past-month e-cigarette use. Dual users reported greater e-cigarette dependence, alcohol use, current cannabis use, and endorsement of nonprescription opioid use. Conclusions/Importance: Importantly, this work suggests that adults who use both combustible and e-cigarettes may constitute a group more vulnerable to experiencing problematic substance use and more severe e-cigarette dependence than exclusive e-cigarette users.
近年来，电子烟（e-cigarettes）越来越受欢迎。现有证据表明，单独使用电子烟比可燃香烟的危害小，但新出现的研究表明，成年人主要将电子烟与可燃香烟一起使用（即双重使用）。尽管有这些数据，但对于完全使用电子烟和双重使用者在物质使用依赖和成年人行为等方面可能存在哪些差异，人们知之甚少。
因此，本项目研究了完全使用电子烟和双重使用者在电子烟依赖、有问题的酒精使用、大麻使用和非医疗处方类阿片类药物使用（例如美沙酮和羟考酮）方面的差异。
参与者包括 531 名（53.6%为女性；M = 35.29 岁，SD = 10.44）过去一个月有电子烟使用经历的成年人。双重使用者报告称电子烟依赖、酒精使用、当前大麻使用和非处方类阿片类药物使用的情况更为严重。
结论/重要性：重要的是，这项工作表明，同时使用可燃香烟和电子烟的成年人可能比仅使用电子烟的成年人更容易出现有问题的物质使用和更严重的电子烟依赖。
