Students aged 18 and older, black students, and students with parents with lower education levels were more likely than others to report no nonmedical amphetamine use, despite reporting
nonmedical Adderall use, the study found.
Though nearly 8 percent of the students reported nonmedical amphetamine use and about 7 percent reported
nonmedical Adderall use in the past year, about 29 percent of
nonmedical Adderall users reported no nonmedical amphetamine use.
