Measure
This is Quitting
Participants will be enrolled to receive messages from This is Quitting. Users receive one age-appropriate message per day tailored to their enrollment date or quit date, which can be set and reset via text message. Those not ready to quit receive 4 weeks of messages focused on building skills and confidence. Users who set a quit date receive messages for a week preceding it and 8 weeks afterward that include encouragement and support, skill- and self-efficacy building exercises, coping strategies, and information about the risks of vaping, benefits of quitting, and cutting down to quit. Keywords COPE, STRESS, SLIP, and MORE provide on-demand support. This is Quitting: Text message-based intervention for quit vaping support.
Assessment Only Control
After an initial enrollment message, participants will be contacted monthly to assess e-cigarette use. At the end of the study data collection period, they will receive information on how to sign up for This is Quitting if they are interested in the program. Assessment only control: Assessment only
Waitlist Control
After an initial enrollment message, participants will receive no contact from study staff except for 1-month and 7-month follow-up assessments.

Waitlist control: No contact until follow-up survey, waitlisted to receive intervention post study
