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.
