Figure 2.8 is titled "Past Month Illicit Drug Use among Persons Aged 12 or Older, by Race/Ethnicity: 2002 and 2003." It is a bar graph, with the following note below the graph: "Statistically significant differences (at 0.05 level) between 2002 and 2003 are denoted by '+.'"

There are seven categories of race/ethnicity: white, black or African American, American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, Asian, two or more races, and Hispanic or Latino. Within each of the race and ethnicity categories there is a bar for 2002 and a bar for 2003.
