Avoidance biases for vaping stimuli among college students with electronic-cigarette use

Previous research has suggested that individuals who smoke demonstrate a behavioral tendency to approach rather than avoid smoking-related stimuli (i.e., approach bias). This study assessed whether 149 undergraduates with varying levels of e-cigarette use demonstrated an approach bias for vaping-related stimuli on an Approach-Avoidance Task (AAT). In contrast to our hypotheses, participants with e-cigarette use demonstrated a significant avoidance bias to vaping-related stimuli, and this effect appeared to be primarily driven by female e-cigarette users. Further, we found that more severe e-cigarette use was associated with numerous adverse outcomes, including reduced quality of life and increased vaping cravings, depressive symptoms, perceived stress, and cannabis use severity. Overall, our findings elucidate various negative impacts of e-cigarette use and suggest a potential role for sex differences in approach-avoidance tendencies toward vaping-related stimuli among young adults.
