What this research studies

This research investigates how cannabis use changes throughout pregnancy, focusing on the first trimester and its potential effects on both mothers and their babies. By recruiting 1,200 pregnant individuals from clinical sites in Maryland and California, the study aims to gather longitudinal data on cannabis use trajectories, including factors that influence changes in usage. The goal is to better understand the risks associated with cannabis exposure during pregnancy and to inform counseling and treatment strategies for expecting mothers.

Who could benefit from this research

Good fit: Ideal candidates for this research are pregnant individuals who use cannabis or are considering its use during their pregnancy.

Not a fit: Patients who are not pregnant or those who do not use cannabis may not receive any benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved maternal and child health outcomes by providing insights into safe cannabis use practices during pregnancy.

How similar studies have performed: Previous research has indicated risks associated with cannabis use during pregnancy, but this study aims to provide novel longitudinal insights into usage patterns.
