Cannabis Use and Brain development Study (CUBS)

Cannabis Use and Brain development Study (CUBS)

The purpose of the CUB Study is to improve our understanding of brain development in infants whose mothers used cannabis during pregnancy and in those whose mothers did not. Although cannabis use has increased among pregnant and non-pregnant people nationwide, there is still limited and often conflicting scientific data available to help future parents understand the risks and benefits associated with using cannabis as an alternative interventions while pregnant. Through observational and neurobehavioral measures, we will follow participants from their first trimester of pregnancy through their child’s first 18 months of life. Our goal is to learn new information that will provide guidance for medical professionals and help pregnant people make informed choices about cannabis use for themselves and their families.

Participants are eligible to receive $350 or more throughout the duration of this study. Participants may also receive MRIs of their babies brains as well as developmental feedback reports.

We are currently recruiting pregnant individuals who have already made the personal choice to use or not use cannabis during their first trimester.
