Who could benefit from this research

Could help

Ideal candidates for this research include pregnant individuals and their partners who have used alcohol or cannabis before or during pregnancy.

Less likely to help

Patients who have not used alcohol or cannabis during the relevant time periods may not benefit from this research.

What this research studies

This research aims to understand the patterns of alcohol and cannabis use among individuals before and during pregnancy, including the biological fathers. It will gather data on how these substances are used together and their potential effects on fetal development. The study will focus on both maternal and paternal substance use to assess risks associated with prenatal exposure. By collecting this information, the research seeks to lay the groundwork for a larger study in the future.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and prevention of adverse outcomes in pregnancies affected by substance use.

How similar studies have gone: While there is evidence from animal models regarding the risks of co-exposure to alcohol and cannabis, this specific investigation in pregnant populations is novel and has not been extensively studied.
