AbstractBackground: Electronic nicotine delivery systems (ENDS), especially vaping, have increased in use and resulted in severe lung injuries (EVALI). In 2020, there were nearly 3.6 million middle school and high school (HS) students who vape. More research is needed to identify effective teaching strategies for adolescents on ENDS. Our previous research found that high school students’ experiences with vaping were related to social and behavioral influences, a knowledge deficit, and media exposure. They suggested a video educational intervention.
