Abstract
Introduction: Cannabis is one of the most commonly used illicit drugs during pregnancy in the United States and this prevalence may rise with a growing number of states legalizing its use. We aimed to describe the rate of its use during pregnancy and evaluate its adjusted effect on obstetric and neonatal outcomes.
Methods: We performed a retrospective population-based cohort study composed of 12 million births in the United States between 1999 and 2013, extracted from the National Inpatient Sample, compiled by the Healthcare Cost and Utilization Project. Births to mothers abusing or dependent on cannabis were identified using ICD-9 codes and were compared to unexposed women. The adjusted effect of cannabis exposure during pregnancy on various obstetrical and neonatal outcomes was assessed with the use of unconditional logistic regression.
Results: There were 66,925 births to mothers using cannabis with an incidence rising from 0.28% in 1999 to 0.95% in 2013, p
