"• Approximately 3 million full-time workers (2.6 percent) aged 18 to 64 met the criteria for past year illicit drug dependence or abuse (Figure 2.3 and Table 2.4).

"• Approximately 7.5 percent of 18- to 25-year-old workers had past year illicit drug dependence or abuse. This was higher than among all other age groups studied (26- to 34-year-olds [3.3 percent], 35- to 49-year-olds [1.9 percent], and 50- to 64-year-olds [0.7 percent]) (Figure 2.3 and Table 2.4).

"• Males were nearly twice as likely as females to meet the criteria for past year illicit drug dependence or abuse (3.3 vs. 1.8 percent) (Figure 2.4 and Table 2.4).

"• Hispanics (3.2 percent) had a higher prevalence of past year illicit drug dependence or abuse than non-Hispanics (2.6 percent) (Figure 2.8 and Table 2.4).

"• Within non-Hispanic subgroups, Asians had the lowest prevalence of past year illicit drug dependence or abuse (1.1 percent). This was lower than non-Hispanic white adults (2.5 percent), black (2.9 percent) adults, American Indian or Alaska Native (4.5 percent) adults, and adults reporting two or more races (4.3 percent) (Figure 2.8 and Table 2.4)."
