Association Between Self-reported Prenatal Cannabis Use and Maternal, Perinatal, and Neonatal Outcomes.

ABSTRACT:

Importance

Recent evidence suggests that cannabis use during pregnancy is increasing, although population-based data about perinatal outcomes following in utero exposure remain limited.

Objective

To assess whether there are associations between self-reported prenatal cannabis use and adverse maternal and perinatal outcomes.

Design, setting, and participants

Population-based retrospective cohort study covering live births and stillbirths among women aged 15 years and older in Ontario, Canada, between April 2012 and December 2017.

Exposures

Self-reported cannabis exposure in pregnancy was ascertained through routine perinatal care.

Main outcomes and measures

The primary outcome was preterm birth before 37 weeks' gestation. Indicators were defined for birth
