Behavior was studied in 15 rhesus monkey mother-infant pairs, 5 of whom were exposed to delta-9-tetrahydrocannabinol continuously throughout gestation and the nursing period via drug treatment of mother (2.4 mg/kg /day). The drug-exposed mother-infant pairs were similar to nontreated controls in the amount and types of activity displayed at 10 and 90 days of age, and adequate maternal care was demonstrated by all mothers. Drug-exposed pairs, however, showed an increase in interaction patterns that signal the onset of mother-infant independence at about 3 months of age. This finding suggests that mother-infant attachment may be a behavioral system that is particularly sensitive to modification by perinatal exposure to psychoactive drugs.
