Note. N = 409. Maternal substance use is expressed as median, minimum, and maximum due to skewed distributions. Median values based only on mothers who reported or acknowledged drug use at birth within the subsample of 409 children; drug use composites were calculated as follows: (number of weeks used) × (usual number of days per week) × (usual dose per day). CE = cocaine-exposed.

n = 197.

n = 212.

p < .01, between-group comparison of percentage reporting drug use (Columns 2 and 4; p < .01 for these comparisons).

p < .05, between-group comparison of median maternal drug use (Columns 1 and 3).
