‡Reporting standards not met. Either there are too few cases for a reliable estimate or the coefficient of variation (CV) is 50 percent or greater.
1 The term "anywhere" is not used in the Youth Risk Behavior Survey (YRBS) questionnaire; students were simply asked how many times during the previous 30 days they had used marijuana.
2 In the question about using marijuana at school, "on school property" was not defined for survey respondents.
3 Data on marijuana use at school were not collected from 2013 onward.
4 Students were asked which sexual orientation--"heterosexual (straight)," "gay or lesbian," "bisexual," or “not sure"--best described them.
NOTE: Race categories exclude persons of Hispanic ethnicity. Detail may not sum to totals because of rounding.
