The goal of this intervention development and pilot clinical trial is to determine whether receiving the brief online intervention results in greater reductions in past 7-day e-cigarette use frequency and smoking susceptibility over an 8-week period compared to receiving the control condition in young adults who currently use e-cigarettes. Participants in the experimental condition will be asked to complete the 30-minute mobile-based program. Participants in the assessment-only control will be given the option to access the intervention after they complete their final survey at 8 weeks. All participants will complete our online surveys at baseline as well as 2-weeks, 4-weeks, and 8-weeks post-randomization. Researchers will compare outcomes among the intervention and control groups to determine the efficacy of the intervention.

Smoking Susceptibility
4-item Expanded Susceptibility to Smoking Index (ESSI)
Time frame: 8 weeks
Perceived harms and benefits of vaping
Using the 21-item Short Form Vaping Consequences Questionnaire (S-VSQ), participants will rate the likelihood that each consequence will occur when they vape.
Time frame: 8 weeks
Perceived harms and benefits of smoking
Using the 21-item Short Form Smoking Consequences Questionnaire (S-SCQ), participants will rate the likelihood that each consequence will occur when they smoke.
Time frame: 8 weeks
Motivation to vape
Participants will select which option best describes their interest in e-cigarette use: plan to stop (coded as 1), decrease (2), continue (3) or increase (4) vaping.

Time frame: 8 weeks
Vaping quit attempts
During follow-up assessments, participants will report on the number of times they have stopped vaping for one day or longer because they were trying to quit vaping.
