! Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.

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 majijuana at school, 'on school property' was not defined for survey respondents. Detail may not sum to totals because of rounding.
