Figure 6.4 is titled "Perceived Great Risk of Use of Selected Illicit Drugs among Youths Aged 12 to 17: 2002 through 2004." It is a bar graph, where selected illicit drug use behaviors are shown on the horizontal axis, and the percentage perceiving great risk is shown on the vertical axis. For each of the four behavior categories there are bars representing 2002, 2003, and 2004. Tests of statistical significance at the .05 level were performed between 2003 and 2004 estimates and between 2002 and 2004 estimates; significant results are indicated where appropriate.
The percentage of youths who perceived that smoking marijuana once a month is a great risk was 32.4 percent in 2002, 34.9 percent in 2003, and 35.0 percent in 2004. The difference between the 2004 estimate and 2002 estimate was significant.
