Marijuana and cannabis-containing products are growing in popularity and availability in the United States, and use during pregnancy has increased dramatically. The overarching aim of this proposal is to provide pilot data for a submission which will explore the impact of chronic maternal marijuana use (primary or secondary) on fetal functioning, maternal reflective functioning and infant birth and neurodevelopmental outcomes. Chronically marijuana using pregnant women in treatment at the Center for Addiction and Pregnancy will be enrolled and asked to provide information about participants' marijuana and other licit and illicit substance use and feelings about parenting and participants' infant and undergo fetal monitoring at 36 weeks gestation. The neonates will undergo neurobehavioral examination during the first and fourth weeks of life.

| Maternal-fetal monitoring | Device | Maternal-fetal monitoring evaluates fetal and maternal heart rate, maternal respirations, fetal movement, and maternal skin conductance (a way to monitor emotional response) | ||
| NICU Network Neurobehavioral Scale | Other | Evaluates neurobehavioral organization, neurological reflexes, motor development, and signs of stress and withdrawal of substance-exposed infants. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Prevalence of maternal cannabis use disorder | Rates of Cannabis use disorder among pregnant women reporting primary or secondary (i.e. first or second drug of choice) cannabis use during pregnancy. | The first day of study enrollment and again at infant delivery |
| Fetal functioning as assessed by fetal heart rate | Fetal heart rate in beats per minute will be measured. | One day during 36th weeks of gestation |
| Fetal functioning as assessed by fetal movement | Fetal movement: number and length in msecs of bouts of fetal movement as determined by fetal actograph testing | One day during 36th weeks of gestation |

| Change in Maternal reflective functioning as assessed by the Parental Reflective Functioning Questionnaire | Responses that evaluate the mother's ability to reflect on and interpret her own behavior and that of her child in terms of mental states and intentions; this will be assessed using the Parental Reflective Functioning Questionnaire. | At 36 weeks of gestation, postpartum week 1, postpartum week 4 |
