Opioid Use Disorder in Pregnancy in Long-Term Maternal/Infant Outcomes

Pregnant Mothers must be taking buprenorphine / subutex for opioid use disorder.

Mothers who consent will be given a fetal MRI and after the baby is born, a neonatal MRI.

Throughout the pregnancy, Mothers will be participating in blood collection throughout the study. At enrollment, we will collect DNA, Genetic and PK blood specimens, then throughout the study, we will be collecting random PK samples.
