Note: Drinking volume, marijuana use, illicit drugs used, alcohol problems and externalizing problems were all correlated at p<.0001; r’s ranged from .29 for drinking volume and externalizing to .74 for illicit drug use and alcohol problems. L, left hemisphere; R, right hemisphere; OFC, orbitofrontal cortex; PFC, prefrontal cortex; mDPFC, dorsomedial prefrontal cortex; BA, Brodmann’s Area; bolded values represent significant differences at p<.01.
