Kind: research · Impact: medium

## In brief

- A study of more than 2 million California deliveries found that women diagnosed with cannabis use disorder during pregnancy were more likely to visit an emergency room for a psychiatric problem in the year after giving birth.
- The reported finding is an association; the source does not establish that cannabis use causes the postpartum psychiatric emergencies.

## Why it matters

The study links a diagnosed cannabis use disorder during pregnancy with higher rates of postpartum psychiatric emergency visits, which may matter for clinicians screening and following up pregnant and postpartum patients.
