Key Points

Question  Are adverse neonatal outcomes associated with exposure to marijuana among mothers during pregnancy?

Findings  In this meta-analysis of 16 studies including 59 138 patients, maternal marijuana exposure during pregnancy was associated with increased risk of preterm deliveries and neonatal intensive care unit admission and decreased mean birth weight, 1-minute Apgar score, and head circumference of babies. There were no differences in mean 5-minute Apgar score or total infant length.

Meaning  This study found that women using marijuana during pregnancy may be at increased risk of some adverse neonatal outcomes.
