Marijuana Use During Pregnancy Linked to Unhealthy Outcomes, Study Finds

Heavier and ongoing use throughout pregnancy associated with higher risks, with about 26% of pregnant marijuana users experiencing an unhealthy outcome.

Marijuana use during pregnancy is linked to unhealthy outcomes, particularly low birth weight babies, according to a new study.
Heavier cannabis use during pregnancy is associated with higher risks, with ongoing use throughout pregnancy and higher levels of exposure posing the greatest risks.
The study, which analyzed urine samples from over 9,000 pregnant women, found that about 26% of pregnant marijuana users experienced an unhealthy pregnancy outcome, compared to 17% of those who didn't use marijuana.
Researchers speculate that long-term cannabis exposure might interfere with the blood supply to the placenta, which provides a growing fetus with oxygen and nutrients.
The research team urges people who are considering using marijuana during their pregnancy to consult with their doctor, as there may be alternative therapies that can help mitigate symptoms.
