What You Need to Know
Information for expectant parents based on current medical research
Cannabis (marijuana, weed, CBD products) is a plant that contains chemicals that affect your brain and body.
It can be smoked, vaped, eaten in foods, or used as oils.
Many people use it to feel relaxed, reduce nausea, or manage stress.
Between 6 and 20 out of every 100 pregnant people report using cannabis or CBD products.
Use has increased in recent years, especially in early pregnancy.
A large study looked at over 320,000 pregnancies between 2011 and 2019.
Study from Kaiser Permanente Northern California health system
17% higher risk for gestational hypertension
8% higher risk for this serious condition
19% higher risk (placenta separating early)
More likely to gain above recommended amounts
Higher risk does not mean it will definitely happen.
Most people who use cannabis during pregnancy do not develop these complications.
But your chance is somewhat higher compared to not using cannabis.
The research showed a dose-response relationship.
Stopping or reducing use may lower your risk.
| Condition | Why It's Important |
|---|---|
| High Blood Pressure | Can affect baby's growth and increase health risks |
