Abstract

E-cigarette use is prevalent, and rates of use continue to increase. Although e-cigarettes are often used to help combustible users quit or reduce smoking, some use e-cigarettes in the absence of combustible cigarettes, increasing risk for smoking combustible cigarettes. Yet, little research has examined individual vulnerability factors implicated in transitioning from exclusive e-cigarettes use to dual use of combustible cigarettes. Social anxiety may be one such factor given it is related to a variety of negative smoking-related outcomes. Thus, the current study tested whether social anxiety was related to using e-cigarettes before smoking combustibles among 226 current undergraduate dual users (use both e-cigarettes and combustible cigarettes). Most dual users reported initiating with e-cigarettes (67%). Those who initiated with e-cigarettes reported statistically significantly greater negative reinforcement (d = 0.59) and weight control expectancies (d = 0.37) and greater social anxiety (d = 0.37) than those who initiated with combustibles. Social anxiety was indirectly related to e-cigarette initiation via negative and weight control expectancies. Findings add to a growing literature that dual users initiated with e-cigarettes and extend understanding of this phenomenon by identifying that socially anxious persons may be especially vulnerable to doing so, at least partially due to expectations regarding e-cigarette's ability to manage negative affect and/or weight.
