Clinical Takeaway
Clinical Takeaway: Maternal cannabis use during peripregnancy (3 months before conception through delivery) showed associations with behavioral and developmental outcomes in young children, with different patterns observed between children with and without autism spectrum disorder symptoms. The study indicates that ASD status may modify how prenatal cannabis exposure affects developmental trajectories in early childhood. Healthcare providers should counsel women of reproductive age about potential neurodevelopmental risks associated with peripregnancy cannabis use.

Abstract: Some studies report increased prevalence of autism spectrum disorder (ASD) and associated symptoms with prenatal cannabis exposure. We examined whether associations of maternal cannabis use from 3 months preconception through delivery (“peripregnancy”) with behavior and development in the offspring varied with the presence of ASD symptoms. Children ages 30-68 months with ASD symptoms (i.e., met study criteria for ASD or had ASD symptoms on standardized assessments or community ASD diagnosis, N = 2734) and without ASD symptoms (other developmental delay/disorders or general population sample, N = 3454) were evaluated with the Child Behavior Checklist and Mullen Scales of Early Learning. We examined cannabis use during three time periods: peripregnancy, pregnancy, and only preconception. Peripregnancy cannabis exposure was reported for 6.0% of children with and 4.6% of children without ASD symptoms. Preconception-only cannabis use (versus no use) was associated with more aggressive behavior, emotional reactivity, and sleep problems in children with ASD symptoms, but not in children without ASD symptoms. Cannabis use during pregnancy was associated with increased attention and sleep problems in children with ASD symptoms; these associations did not differ significantly by ASD symptoms. Peripregnancy cannabis use was not associated with child developmental abilities regardless of ASD symptoms. In summary, associations of peripregnancy cannabis use with some behavioral outcomes differed in children with and without ASD symptoms. With rising cannabis use among pregnant women, future studies that examine a range of developmental risks associated with timing and patterns of cannabis use prior to conception as well as during pregnancy could inform clinical guidance.
