Abstract
INTRODUCTION: Initiation of e-cigarette use by young adults is a significant public health issue within the debate on vaping. The current study is an exploratory evaluation of brief educational information among young adults and investigated outcomes as a function of JUUL use and smoking status. METHODS: Participants (N = 947) were young adults (<30 years old) recruited from Amazon's Mechanical Turk based on smoking and JUUL use status. Participants completed baseline assessments, viewed a brief JUUL educational handout, and completed post-assessments. RESULTS: There was a significant Time X Group interaction for JUUL-related knowledge (p < .001), with never JUUL/never smokers showing the greatest increase in knowledge. Brief education increased JUUL-related knowledge and risk perceptions and had a modest impact on commitment to quitting and readiness to quit JUUL (all p ≤ 0.001; ds = 0.06-0.74; time × group p > .05 for all contrasts except JUUL-related knowledge). Participants showed modest decreases in interest in future JUUL use, interest in purchasing, and interest in future regular use (all p ≤ 0.001; ds = 0.07-0.08; time × group p > .05 for all contrasts). In terms of smoking outcomes, participants reported reduced perceived harm to others (p < .001; d = 0.09) and decreased intentions to smoke regularly (p = .001; d = 0.07). CONCLUSIONS: Brief education was effective in increasing knowledge and risk perceptions while showing a modest effect on intentions for future use. The information was most effective in increasing knowledge among non-users, suggesting that brief education may be useful for preventing initiation. Analysis of group differences suggest current JUUL use status is more important in informing JUUL-related attitudes than smoking status.
