NOTE: The term "anywhere" is not used in the Youth Risk Behavior Survey (YRBS) questionnaire; students are simply asked how many times during the previous 30 days they used marijuana. In the question that asks students about using marijuana at school, "on school property" was not defined for survey respondents.
