How cannabis use changes during pregnancy
Trajectories of Cannabis Use in Pregnancy
This project will follow pregnant people who use cannabis to track how their use changes across pregnancy and identify factors linked to those patterns.

What this research studies
If you join, you'll be one of about 1,200 pregnant people recruited at prenatal clinics in Maryland and California. Researchers will collect information over time about how much and when you use cannabis during pregnancy, looking for decreases, continued use, or other patterns. They will also gather medical and social information that might influence those patterns and connect use trajectories to pregnancy outcomes. The goal is to help clinicians better support pregnant people who use cannabis and reduce risks to babies.
Who could benefit from this research
Good fit: Pregnant people who currently use cannabis or recently used it and who receive prenatal care at participating clinics in Maryland or California are the best fit to join.
Not a fit: People who are not pregnant, who do not use cannabis, or who cannot attend the participating clinics are unlikely to be helped by this project.
Why it matters
Potential benefit: Could help clinicians give clearer guidance and targeted support to reduce pregnancy and child health risks from cannabis exposure.
How similar studies have performed: Most prior research has been cross-sectional and binary (use versus abstinence), so long-term trajectory tracking like this is relatively new and fills an evidence gap.
