The coronavirus disease 2019(COVID-19)pandemic has raised concerns about the mental health and social well-being of youth,including its potential to increase or exacerbate substance use behaviors[1].Among adolescents,the COVID-19pandemic has resulted in limited face-to-face school contact and thus missed milestones in preventing alcohol and substance use.
