About The Study: Cannabis use in pregnancy was associated with greater odds of preterm birth, small for gestational age, and low birth weight even after adjusting for co-use of tobacco products, and confidence in these findings increased from low in the prior review to moderate in the current meta-analysis. The findings of this study may help inform patient counseling and future public health policies.
