Who could benefit from this research

Could help

Ideal candidates for this research are pregnant women who use marijuana, particularly those from underserved communities.

Less likely to help

Patients who are not pregnant or who have not used marijuana during pregnancy may not benefit from this research.

What this research studies

This research focuses on understanding the effects of prenatal marijuana use on the placenta and its implications for infant neurodevelopment. By examining genomic pathways in the placenta, the study aims to identify biomarkers that indicate fetal harm and develop new screening tools and interventions. The research is particularly relevant given the increasing rates of cannabis use among pregnant women, especially in underserved populations. The findings could lead to better protective measures for infants exposed to cannabis in utero.

Why it matters

Potential benefit: If successful, this research could lead to improved screening and intervention strategies for infants affected by prenatal cannabis exposure.

How similar studies have gone: Other research has shown promising results in understanding the effects of prenatal substance exposure, but this specific genomic approach is relatively novel.
