Question  What are the characteristics of current (past 30-day) e-cigarette use among US high school and middle school students in 2020?

Findings  This survey study of 14 531 students found that among the 19.6% of high school students and 4.7% of middle school students who currently used e-cigarettes in 2020, 38.9% of high school users and 20.0% of middle school users self-reported use on 20 to 30 days during the past 30 days, and most reported flavored e-cigarette use.

Meaning  These results suggest that although current e-cigarette use among youth significantly decreased during 2019 to 2020, use prevalence, frequent use, and flavored e-cigarette use remained high.
