Cannabis use during pregnancy carries significant risks, and major medical organizations recommend against it. The primary concerns include low birth weight, preterm birth, stillbirth, and potential effects on fetal brain development. THC, the main psychoactive compound in cannabis, crosses the placenta and can reach the fetus.
What Are the Main Risks of Cannabis Use During Pregnancy?
Research links cannabis use during pregnancy to several negative outcomes. These risks may vary based on how often and how much cannabis is used, but no safe level has been established.
Cannabis and Pregnant Women: What You Need to Know
- Low birth weight: Babies born to mothers who use cannabis may weigh less than average.
- Preterm birth: Cannabis use is associated with a higher chance of birth before 37 weeks.
- Stillbirth: Some studies suggest an increased risk of stillbirth, though more research is needed.
- NICU admission: Infants may require specialized care after birth.
- Developmental issues: Long-term effects on attention, memory, and behavior have been observed in some children.
How Does Cannabis Affect the Fetus?
THC crosses the placenta and binds to cannabinoid receptors in the fetal brain. The endocannabinoid system plays a role in brain development, so disrupting it could have lasting effects. Smoking cannabis also exposes the fetus to carbon monoxide and other harmful chemicals, which can reduce oxygen supply.
Additionally, cannabis products may contain contaminants like pesticides, heavy metals, or mold. These substances can be harmful to both mother and fetus.
Is Any Amount of Cannabis Safe During Pregnancy?
No. The American College of Obstetricians and Gynecologists (ACOG) advises against cannabis use during pregnancy. The U.S. Food and Drug Administration (FDA) also recommends against it. There is no known safe amount, and no safe trimester. Some pregnant people use cannabis to manage nausea, but safer, approved treatments are available. Always talk to your healthcare provider about options.
What About CBD During Pregnancy?
CBD products are not recommended during pregnancy. Many CBD products contain THC, even if labeled otherwise. They may also have contaminants. The FDA has not approved CBD for use during pregnancy, and its effects on fetal development are not well understood. Avoiding CBD is the safest choice.
What Should You Do If You Are Pregnant and Using Cannabis?
If you are pregnant and using cannabis, talk to your healthcare provider. They can provide non-judgmental support and help you find safe alternatives for any symptoms you are managing. Quitting cannabis is best for your baby, but your provider can help you do so safely.
