Description
Summary:•Marijuana co-use with alcohol and tobacco is common during pregnancy.•Postpartum marijuana use linked with depressive symptoms and shortened breastfeeding.•Marijuana use during pregnancy associated with lower mean infant birthweight.•After adjustment for confounders, association no longer significant. We sought to describe the correlates of marijuana use during and after pregnancy, and to examine the independent relationship between prenatal marijuana use and infant outcomes. We used state-specific data from the Pregnancy Risk Assessment Monitoring System (N = 9013) to describe correlates of self-reported prenatal and postpartum marijuana use. We estimated differences in mean infant birth weight and gestational age among prenatal marijuana users and nonusers, controlling for relevant covariates (i.e., cigarette smoking). Respectively, 4.2% (95% CI: 3.8–4.7) and 6.8% (95% CI: 6.0–7.7) of women reported using marijuana during and after pregnancy. Compared to nonusers, prenatal marijuana users were more likely to be ≤24 years; non-Hispanic white, not married, have
