Marijuana and Pregnancy
Marijuana use during pregnancy can be harmful to a baby’s health and cause many serious problems, including stillbirth, preterm birth, and growth and development issues.
Associations Between Prenatal Cannabis Exposure and Childhood OutcomesResults From the ABCD Study
Abstract
Importance In light of increasing cannabis use among pregnant women, the US Surgeon General recently issued an advisory against the use of marijuana during pregnancy.
Objective To evaluate whether cannabis use during pregnancy is associated with adverse outcomes among offspring.
Design, Setting, and Participants In this cross-sectional study, data were obtained from the baseline session of the ongoing longitudinal Adolescent Brain and Cognitive Development Study, which recruited 11 875 children aged 9 to 11 years, as well as a parent or caregiver, from 22 sites across the United States between June 1, 2016, and October 15, 2018.
Exposure Prenatal cannabis exposure prior to and after maternal knowledge of pregnancy.
Main Outcomes and Measures Symptoms of psychopathology in children (ie, psychotic-like experiences [PLEs] and internalizing, externalizing, attention, thought, and social problems), cognition, sleep, birth weight, gestational age at birth, body mass index, and brain structure (ie, total intracranial volume, white matter volume, and gray matter volume). Covariates included familial (eg, income and familial psychopathology), pregnancy (eg, prenatal exposure to alcohol and tobacco), and child (eg, substance use) variables.
Results Among 11 489 children (5997 boys [52.2%]; mean [SD] age, 9.9 [0.6] years) with nonmissing prenatal cannabis exposure data, 655 (5.7%) were exposed to cannabis prenatally. Relative to no exposure, cannabis exposure only before (413 [3.6%]) and after (242 [2.1%]) maternal knowledge of pregnancy were associated with greater offspring psychopathology characteristics (ie, PLEs and internalizing, externalizing, attention, thought and, social problems), sleep problems, and body mass index, as well as lower cognition and gray matter volume (all |β| > 0.02; all false discovery rate [FDR]–corrected P < .03). Only exposure after knowledge of pregnancy was associated with lower birth weight as well as total intracranial volume and white matter volumes relative to no exposure and exposure only before knowledge (all |β| > 0.02; all FDR-corrected P < .04). When including potentially confounding covariates, exposure after maternal knowledge of pregnancy remained associated with greater PLEs and externalizing, attention, thought, and social problems (all β > 0.02; FDR-corrected P < .02). Exposure only prior to maternal knowledge of pregnancy did not differ from no exposure on any outcomes when considering potentially confounding variables (all |β| < 0.02; FDR-corrected P > .70).
Conclusions and Relevance This study suggests that prenatal cannabis exposure and its correlated factors are associated with greater risk for psychopathology during middle childhood. Cannabis use during pregnancy should be discouraged.
American Journal of Obstetrics & Gynecology-Recommendations from cannabis dispensaries on first trimester marijuana use
Objective
To characterize recommendations given to pregnant women by Colorado marijuana dispensaries regarding use of cannabis products for nausea during the first trimester
Study Design
This was a statewide cross-sectional study in which advice about cannabis product use was requested using a mystery caller approach.
Conclusion
Nearly 70% of randomly selected Colorado marijuana dispensaries recommended cannabis products to treat nausea in the first trimester. Few dispensaries encouraged discussion with a health care provider without prompting. Policy and education efforts should target dispensaries as legalization expands.

What You Should Know About Using Cannabis, Including CBD, When Pregnant or Breastfeeding
FDA strongly advises against the use of cannabidiol (CBD), tetrahydrocannabinol (THC), and marijuana in any form during pregnancy or while breastfeeding.
Every Brain Matters is a unifying alliance of organizations and individuals that educate about the dangers of marijuana and the drug culture expansion. We call for a cultural movement by encouraging widespread use of Every Brain Matters merchandise t
What should you remember about using cannabis or cannabis-derived products?
If you are considering using cannabis, or any products containing THC or CBD, you should be aware of the following:
- FDA strongly advises that during pregnancy and while breastfeeding, you avoid using CBD, THC, or marijuana in any form.
- Although many of these products are being sold, FDA has not approved these products, other than one prescription CBD drug product and two prescription drug products containing dronabinol, a synthetic version of THC (which are approved to treat certain side effects of HIV-AIDS or chemotherapy). All three of these prescription products have associated risks and side effects.
- Always talk with your doctor, nurse, or pharmacist before taking any medicines, vitamins, or herbs while pregnant or breastfeeding.
Do not put yourself or your baby at risk by using cannabis products while pregnant or breastfeeding. Check out these links to learn more about cannabis, marijuana, CBD, and THC, and about taking medicines while you are pregnant.

Associations Between Prenatal Cannabis Exposure and Childhood OutcomesResults From the ABCD Study
Key Points
Question Is prenatal exposure to cannabis associated with child outcomes?
Findings This cross-sectional analysis of 11 489 children (655 exposed to cannabis prenatally) found that prenatal cannabis exposure after maternal knowledge of pregnancy was associated with greater psychopathology during middle childhood, even after accounting for potentially confounding variables.
Meaning Prenatal cannabis exposure may increase risk for psychopathology; consistent with recent recommendations by the Surgeon General of the United States, these data suggest that cannabis use during pregnancy should be discouraged by clinicians and dispensaries.
Parental Cannabis Use Tied to Child Psychosis Risk
April 11, 2018
FLORENCE, Italy — Both mothers and fathers who use cannabis during pregnancy are more likely to have children who experience psychotic symptoms, new research suggests.
An analysis of more than 3500 families showed that maternal cannabis use was linked to a 38% increased risk for psychotic symptoms in offspring at 10 years of age; cannabis use among fathers was associated with a 44% increased risk.
