This issue of "The NSDUH Report" examines the rates of nonmedical use of Adderall[R] in the past year among full-time college students aged 18 to 22 and comparably aged persons who were not full-time college students. All findings presented in this report are annual averages based on combined 2006 and 2007 data. Full-time college students aged 18 to 22 were twice as likely as their counterparts who were not full-time college students to have used Adderall[R] nonmedically in the past year (6.4 vs. 3.0 percent). Full-time college students who were nonmedical users of Adderall[R] were almost 3 times as likely as those who had not used Adderall[R] nonmedically to have used marijuana in the past year (79.9 vs. 27.2 percent), 8 times more likely to have used cocaine in that period (28.9 vs. 3.6 percent), 8 times more likely to have been nonmedical users of prescription tranquilizers (24.5 vs. 3.0 percent), and 5 times more likely to have been nonmedical users of prescription pain relievers (44.9 vs. 8.7 percent). Nearly 90 percent of full-time college students who used Adderall[R] nonmedically in the past year were past month binge alcohol users, and more than half were heavy alcohol users.
