The main questions it aims to answer are:\n\n* Compared to the control condition, does the intervention reduce e-cigarette use frequency in teenagers?\n* Compared to the control condition, does the intervention reduce risk to start smoking cigarettes in teenagers? Researchers will compare the digital intervention to see if it leads to greater reductions in e-cigarette use and smoking risk than a waitlist control condition.\n\nParticipants will complete 5 brief online surveys across 12 weeks, and some will be selected to do a post-intervention virtual interview. In this interview, participants will be asked to share their opinions about the intervention and identify areas that need refinement.",[27,28],"E-cigarette Use","Cigarette Smoking Risk",[30,31,32,33],"E-cigarette","Tobacco","Nicotine addiction","mHealth","NOT_YET_RECRUITING","2026-05-31",{"date":37,"type":38},"2026-06-03","ACTUAL",{"date":40,"type":21},"2026-07-01",{"date":42,"type":21},"2027-03-30",{"name":44,"class":45},"University of Southern California","OTHER"]
