Background: The potential risks of prenatal cannabis use may vary depending on how cannabis is administered, but little is known about modes of prenatal cannabis use. This study characterized prevalence and sociodemographic correlates of modes of prenatal cannabis use in California.
Methods: This cross-sectional study included patients with pregnancies between January 1, 2021 and December 31, 2022 in a large healthcare system (3507 pregnancies [3454 individuals]) who self-reported prenatal cannabis use and mode of use (smoke, vape, edibles, dabs, and topicals) during universal screening at entrance to prenatal care.
Objectives: Assessment and counseling are recommended for individuals with prenatal cannabis use. We examined characteristics that predict prenatal substance use assessment and counseling among individuals who screened positive for prenatal cannabis use in prenatal settings.
Methods: Electronic health record data from Kaiser Permanente Northern California's Early Start perinatal substance use screening, assessment, and counseling program was used to identify individuals with ≥1 pregnancies positive for prenatal cannabis use.
Importance: It is unknown whether state recreational cannabis legalization (RCL) is related to increased rates of prenatal cannabis use or whether RCL-related changes vary with cannabis screening methods or the local policy environment.
Objective: To test whether RCL in California was associated with changes in prenatal cannabis use rates, whether changes were evident in both self-report and urine toxicology testing, and whether rates varied by local policies banning vs allowing adult-use retailers post-RCL.
Design, Setting, And Participants: This population-based time-series study used data from pregnancies in Kaiser Permanente Northern California universally screened for cannabis use during early pregnancy by self-report and toxicology testing from January 1, 2012, to December 31, 2019.
Importance: Maternal prenatal cannabis use is associated with adverse neonatal health effects, yet little is known about its association with child developmental outcomes.
Objective: To evaluate associations between maternal prenatal cannabis use in early pregnancy and child early developmental delays.
Design, Setting, And Participants: This cohort study included 119 976 children born to 106 240 unique individuals between January 2015 and December 2019 and followed up to aged 5.
Article Synopsis
- A study was conducted to explore the relationship between maternal cannabis use during early pregnancy and the risk of autism spectrum disorder (ASD) in children, due to a rise in prenatal cannabis use and its potential negative effects on neonatal health.
- The research utilized data from a large cohort of pregnancies (178,948 singleton births) from Kaiser Permanente Northern California between 2011 and 2019, examining factors like maternal age, sociodemographics, and substance use.
- Findings indicated that while 4.7% of mothers screened positive for cannabis use, comprehensive analysis is needed to better understand the implications of maternal cannabis use on child neurodevelopment, specifically in relation to ASD.
