Indicator 16: Students' Use of Marijuana on School Property and Anywhere

In 2007, 20 percent of students in grades 9–12 reported using marijuana anywhere in the past 30 days, while 4 percent reported using marijuana on school property.

In the Youth Risk Behavior Survey, students in grades 9–12 were asked whether they had used marijuana at all (referred to as "anywhere" in this indicator) in the past 30 days as well as whether they had used marijuana on school property.41 In 2007, 20 percent of students in grades 9–12 reported using marijuana anywhere in the past 30 days, while 4 percent reported using marijuana on school property (figure 16.1 and table 16.1).

The percentage of students who reported using marijuana anywhere was higher in 1995 (25 percent) than in 1993 (18 percent). During the second half of the 1990s, there was no measurable change in the percentage of students who reported using marijuana anywhere (it ranged from 25 to 27 percent). Between 1999 and 2007, the percentage of students who reported using marijuana anywhere had declined to 20 percent. However, there was no measurable change in the percentage of students who reported using marijuana anywhere between 2005 and 2007.

With regard to marijuana use on school property, the percentage of students who reported using marijuana was higher in 1995 (9 percent) than the percentage who reported doing so in 1993 (6 percent). Between 1995 and 2007, the percentage of students who reported using marijuana on school property declined from 9 to 4 percent. The percentage of students who reported using marijuana on school property in 2007 was not measurably different from the percentage of students who reported doing so in 1993.

Marijuana use anywhere and on school property varied by students sex and grade level. In every survey year, a greater percentage of males than females reported using marijuana in the past 30 days, both anywhere and on school property. For example, in 2007, 22 percent of males reported using marijuana anywhere in the past 30 days compared to 17 percent of females, and 6 percent of males reported using marijuana on school property compared to 3 percent of females.

In 2007, a smaller percentage of 9th-grade students than students in higher grades reported using marijuana anywhere. In 2007, 15 percent of 9th-grade students reported using marijuana anywhere compared to 19 percent of 10th-graders, 21 percent of 11th-graders, and 25 percent of 12th-graders (figure 16.2 and table 16.1). There were no measurable differences in student reports of marijuana use on school property by grade level in 2007.

In 2007, a smaller percentage of Asian students (9 percent) than students from other racial/ethnic groups (ranging from 18 to 29 percent) reported using marijuana anywhere. A larger percentage of American Indian/Alaska Native students (27 percent) than White students (20 percent), Hispanic students (18 percent), and Asian students (9 percent) also reported using marijuana anywhere. At school, there were generally few differences in the percentage of students who reported using marijuana by race/ethnicity in 2007.

In 2007, the percentage of students who reported using marijuana anywhere (39 states and the District of Columbia) and on school property (38 states and the District of Columbia) varied among the states and the District of Columbia for which data were available. Among these states and the District of Columbia, the percentage of students who reported using marijuana anywhere ranged from 9 percent in Utah to 25 percent in Delaware, Massachusetts, and New Mexico, while the percentage of students who reported using marijuana on school property ranged from 2 percent in Iowa to 8 percent in New Mexico (table 16.2).

This indicator repeats information from the 2008 Indicators of School Crime and Safety report. For more information: Tables 16.1 and 16.2 and Centers for Disease Control and Prevention (2008b).
