E-cigarettes differ from combustible cigarettes in ways that may make it harder to control vaping.  For example, e-cigarettes lack many of the same stopping cues as cigarettes, indoor bans are less common, and discreet use is easy. The goal of this study is to understand uncontrolled vaping and vaping restraint strategies. Study aims are: (1) to develop measures of uncontrolled vaping and restraint strategies; (2) to assess prevalence of and factors related to both uncontrolled vaping and restraint strategies; and (3) to establish the long-term impact of vaping restraint on uncontrolled vaping. To achieve Aim 1, researchers will conduct phone interviews with 8 adolescent (ages 13-17), 8 young adult (ages 18-25), and 8 adult (ages 26 and older) current e-cigarette users to understand how they describe uncontrolled use and vaping restraint and will then develop survey measures. To achieve Aim 2, researchers will survey 1,050 current e-cigarette users (300 adolescents, 300 young adults, and 450 adults) and evaluate the usefulness of the new measures. Researchers will then estimate uncontrolled use and vaping restraint strategies for the nation and examine whether these outcomes are more common among vulnerable populations, certain device type users, and dual users. To achieve Aim 3, researchers will conduct a follow-up online survey with approximately 700 e-cigarette users from the Aim 2 sample to examine how baseline vaping restraint related to uncontrolled vaping and smoking behavior one year later. Findings may inform regulatory activities related to e-cigarettes.
