Title: Adolescents and Alcohol: Acute Sensitivities, Enhanced Intake and Later Consequences
Adolescents ingest more alcohol per occasion than adults do. This age effect is evident not only in human adolescents but also in laboratory animals undergoing this developmental transition, suggesting that such intakes may be partly biologically based. Work using rodent models has revealed that adolescents display an attenuated sensitivity to many alcohol effects likely serving as cues to moderate drinking, but enhanced sensitivity to ethanol-induced social stimulation and rewarding effects. Although limited, available data in human adolescents suggest similar findings. Such a developmental blending of increased and decreased EtOH sensitivities may promote relatively high levels of alcohol intake, especially among at-risk adolescents, potentially leading to lasting adverse consequences. Indeed, recent pre-clinical studies have revealed notable enduring neural and behavioral consequences of adolescent EtOH exposure, including the persistence of adolescent-typical responding to alcohol and other adolescent phenotypes into adulthood.
