Definition: Estimated percentage of public school students in grades 7, 9, 11, and non-traditional programs who have used marijuana in the previous 30 days, by gender, grade level, and frequency (e.g., in 2017-2019, an estimated 1.9% of female 9th graders in California had used marijuana on 20-30 days in the previous month).
Data Source: WestEd, California Healthy Kids Survey (CHKS) & Biennial State CHKS. California Dept. of Education (Aug. 2020).
Footnote: Years presented comprise two school years (e.g., 2017-18 and 2018-19 school years are shown as 2017-2019). County- and state-level data are weighted estimates; school district-level data are unweighted. Students in non-traditional programs are those enrolled in community day schools or continuation education. The notation S refers to (a) data for school districts that have been suppressed because there were fewer than 10 respondents in that group, and (b) data for counties that have been suppressed because the sample was too small to be representative. N/A means that data are not available.
