Definition: Estimated percentage of public school students in grades 7, 9, 11, and non-traditional programs who have ever used marijuana, by level of school connectedness and number of occasions (e.g., in 2017-2019, an estimated 16.8% of California students in grades 7, 9, 11, and non-traditional programs with low levels of school connectedness had used marijuana on seven or more occasions in their lifetimes).
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. Levels of school connectedness are based on a scale created from responses to five questions about feeling safe, close to people, and a part of school, being happy at school, and about teachers treating students fairly. 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.
