| — Not available. ! Interpret data with caution. NOTE: “On school property” was not defined for survey respondents. The term “anywhere” is not used in the YRBS questionnaire; students are simply asked how many times during the past 30 days they used marijuana. The estimate for the United States is drawn from a nationally representative sample of schools and is not the aggregate of participating states. Each state estimate is based on a sample that is representative of that state.
