Abstract or Artist's Statement

The prevalence of opioid use has increased in many populations including pregnant women, which has led to a substantial rise in infants born dependent on opioids due to in utero exposure. Many women use multiple substances aside from opioids during pregnancy, and their infants therefore present with a variety of symptoms. With increasing legalization and changing perception of marijuana, it has become one of the most commonly used substances during pregnancy. Few studies have evaluated concomitant use of marijuana and opioids in pregnancy despite both being implicated in adverse newborn outcomes. The primary aim of this study was to determine the association between marijuana use and pregnancy outcomes in opioid-exposed pregnancies. The secondary aim was to identify, in a sample of women already using opioids, maternal characteristics associated with marijuana use during pregnancy. A retrospective chart review was conducted from July 2011 to June 2016 of all births from 6 delivery hospitals in South-Central Appalachia to determine pregnancy and neonatal outcomes of pregnancies exposed to any form of opioid and positive urine drug screen for marijuana at the time of delivery. 2375 pregnancies met the inclusion criteria with 108 pregnancies positive for marijuana. Student t-test and Chi-Square test were used for group comparison for presence and absence of marijuana. Logistic regression was done for significant confounding variables to find aOR for marijuana exposure for neonatal abstinence syndrome diagnosis, premature birth, and low birth weight. Among opioid using women, marijuana positive women were more likely to be unmarried, nulliparous, and use tobacco and benzodiazepines. Infants born to the marijuana users were likely to be of earlier gestational age (3 days), lower birth weight, and preterm; with preterm birth and low birth weight (mean difference = 265 gms) increased two fold even after controlling for parity, marital status, tobacco and benzodiazepine use with aOR of 2.35 (1.30-4.23) and 2.02 (1.18-3.47) respectively. Ultimately, prenatal use of marijuana in opioid-exposed pregnancies carries significant risk of prematurity and low birth weight. For pregnant women continuing their American College of Obstetricians and Gynecologists recommended medical assisted treatment for opioid use disorder, providers should counsel women to abstain from marijuana during pregnancy.

The prevalence of opioid use has increased in many populations including pregnant women, which has led to a substantial rise in infants born dependent on opioids due to in utero exposure. Many women use multiple substances aside from opioids during pregnancy, and their infants therefore present with a variety of symptoms. With increasing legalization and changing perception of marijuana, it has become one of the most commonly used substances during pregnancy. Few studies have evaluated concomitant use of marijuana and opioids in pregnancy despite both being implicated in adverse newborn outcomes. The primary aim of this study was to determine the association between marijuana use and pregnancy outcomes in opioid-exposed pregnancies. The secondary aim was to identify, in a sample of women already using opioids, maternal characteristics associated with marijuana use during pregnancy. A retrospective chart review was conducted from July 2011 to June 2016 of all births from 6 delivery hospitals in South-Central Appalachia to determine pregnancy and neonatal outcomes of pregnancies exposed to any form of opioid and positive urine drug screen for marijuana at the time of delivery. 2375 pregnancies met the inclusion criteria with 108 pregnancies positive for marijuana.
