The goal of this study is to examine if e-cigarette education messages delivered using a source and presentation tailored to one's vaping status influences young adults' vaping behaviors. The main questions it aims to answer are: 1. Does receiving e-cigarette education messages presented using a source (expert or peer) and sidedness (one or two-sided) optimized for the current vaper group influence vaping cessation among young adults who vape daily? 2. Does receiving e-cigarette education messages presented using a source (expert or peer) and sidedness (one or two-sided) optimized for the non-vaper group influence vaping initiation among young adults who are susceptible to vaping? Participants will be randomly assigned to either the treatment (receiving messages tailored to one's vaping status) or the control (receiving non-tobacco messages) condition and receive SMS three times per week over the course of 6 months. They will complete self-report assessment and show salivary cotinine results for nicotine testing at 4 timepoints.

Self-reported vaping
Past-30-day vaping (yes/no) will be assessed
Time frame: Baseline, six-month
Biochemical confirmation of vaping
Salivary cotinine for nicotine testing
Time frame: Baseline, one-month, three-month, six-month
Harm perceptions
Participants will be asked to indicate the extent to which they think vaping nicotine (using e-cigarettes) is… safe, containing flavors that are safe to use, containing dangerous chemical, harmful to health on a scale from 1 (strongly disagree) to 5 (strongly agree).
Time frame: Baseline, one-month, three-month, six-month
Message perceptions
Participants will be asked to indicate the extent to which they think the message was worth remembering, grabbed their attention, powerful, convincing, meaningful on a scale from 1 (strongly disagree) to 5 (strongly agree).
Time frame: One-month, three-month, six-month
Message liking
Participants will be asked to indicate the extent to which they liked the message they saw on a scale from 1 (dislike very much) to 5 (like very much).
Time frame: One-month, three-month, six-month
Number of days of past-30-day e-cigarette use
Participants will be asked to report the number of days in the past 30 days (between 0 to 30) they used an e-cigarette.
Time frame: From enrollment to the end of study at 24 weeks.
E-cigarette accessibility
Participants will be assessed how they usually purchase e-cigarettes for themselves with categorical response options of…in person, from the Internet, by phone, don't buy their own. This question will only be asked if response indicates participants are between the ages of 18 and 20 AND have used e-cigarettes more than 0 days in the past 30 days.
Time frame: Baseline, one-month, three-month, six-month
