Is Marijuana Use Safe While Pregnant?

As of January 1, 2022, marijuana purchase and use is legal for individuals over 21 in Montana. Though it is legal to use medicinally and recreationally, marijuana use is not without side effects, especially when pregnant.

Risks of Using Marijuana During Pregnancy

As marijuana use began to rise, infants and children became more and more affected. In 2018, the American Academy of Pediatrics released an official recommendation against marijuana use during pregnancy, while breastfeeding, or while in the vicinity of children. (1)

The drug contains nearly 500 chemicals including tetrahydrocannabinol (THC), and these chemicals can pass through a woman’s placenta, directly to the fetus (2) potentially causing:

  • fetal growth restriction (3)

  • greater risk of stillbirth

  • greater risk of pre-term birth

  • low birth weight

  • long-term brain development issues affecting memory, learning, and behavior

Infants born exposed to marijuana in-utero, often exhibit withdrawal symptoms after birth, have sleep disruptions, and encounter challenges as they grow. (4)

Some women believe using marijuana is a safe, natural way to treat morning sickness, but research indicates that it is not safe for a woman or her baby. Be sure to reach out to your healthcare provider for safer alternatives for treating morning sickness.

Similarly, marijuana use while breastfeeding also impacts the brain development of an infant. THC is stored in body fat and slowly released into the body over time. (5) Thus, a baby could still be exposed even after a person has stopped using marijuana.

The CDC also cautions against second-hand marijuana smoke due to chemical exposure risks to babies and children. (4)

Risks of Using Marijuana for Women

It is also important to recognize the risks associated with marijuana use for adults. A few risks to consider include permanent lung injury, dizziness and risk of falling, impaired judgement and risk of injury to yourself or others, and lower oxygen levels in the body that may lead to breathing problems. (6) Some studies also indicate that marijuana use can affect fertility in women due to disruption of hormones and effects on a woman’s menstrual cycle. (4)
