Risks for Baby:^1,2,3,4

Fetal growth restriction and low birth weight

Premature birth (especially with marijuana and cigarette use)

Disrupted brain development and function

Greater risk of stillbirth

Harm from marijuana smoke

Risks for Mother:^1,5,6,7

Increased heart rate and blood pressure

Lung problems (bronchitis and coughing)

Trouble paying attention or thinking clearly

Clumsiness, poor coordination, and poor balance

Mental health disorders (especially with frequent use)

The American College of Obstetricians and Gynecologists (ACOG) recommends that pregnant women or women trying to become pregnant not use marijuana. The negative effects of marijuana on the baby may occur throughout pregnancy, including during the first trimester.^1,2

The Blunt Facts:^1,2,4

THC and other chemicals in marijuana can cross the placenta and enters the baby’s brain.

No amount of marijuana has been proven safe to use during pregnancy.

There is no evidence marijuana is helpful in managing morning sickness.

Use of marijuana during pregnancy is not proven to be safe in any form (smoking, vaping, edibles, or oils) or intended purpose (recreational or medical).

Because THC, the chemical in marijuana responsible for the “high”, is stored in body fat and the brain, and slowly released over time, a baby can be exposed to THC even after a mother has stopped using marijuana.⁴

Marijuana smoke contains many of the same harmful chemicals as tobacco smoke, in some cases in higher amounts. Neither marijuana nor tobacco products should be smoked around a baby or older children.^2,3
