Study assesses the direct effects of prenatal cocaine exposure (PCE) on adolescent internalizing, externalizing, and attention problems, controlling for confounding drug and environmental factors.

The effect of prenatal cocaine exposure (PCE) on externalizing behavior and substance use related problems at 15 years of age was examined. Participants consisted of 358 adolescents (183 PCE, 175 non-cocaine exposed (NCE)), primarily African–American and of low socioeconomic status, prospectively enrolled in a longitudinal study from birth.

Prominent neuroscience models suggest that addictive behavior occurs when environmental stressors and drug-relevant cues activate a cycle of cognitive, affective, and psychophysiological mechanisms, including dysregulated interactions between bottom-up and top-down neural processes, that compel the user to seek out and use drugs.
