Multiple drug use in adults has been shown to result in impaired functioning of the brain’s “frontal system,” producing deficits in concept tracking, shifting, and learning. In the present study, adolescents with histories of severe, though time-limited, polydrug abuse were found to perform as well as nonabusers on two very sensitive indicators of frontal system functioning. The results are discussed in terms of the natural history of drug-related neuropsychological deficits.
