This study reports the prevalence of ever use of marijuana in e-cigarette among U.S. youth in 2020, and changes in prevalence from 2017 to 2020*, by racial and ethnic groups based on National Youth Tobacco Survey (NYTS) data.  In 2020, 5.1 million U.S. middle school (grades 6-8) and high school (grades 9-12) students (1 in 5) reported ever using marijuana in e-cigarettes.  Increases in ever use occurred among all racial and ethnic groups from 2017 to 2020, with Hispanic youths having the highest prevalence and largest percent increase, followed by non-Hispanic Black youths.  Further research is needed to assess why differences in marijuana use in e-cigarettes exist.  Identifying differences in marijuana use in e-cigarettes by racial and ethnic groups opens avenues for targeted interventions.  Evidence-based strategies to reduce marijuana use in e-cigarettes are important for protecting young people from related health risks.

*Marijuana use in e-cigarettes was queried in 2017, 2018, and 2020; it was not queried in 2019.
