Neonatal Abstinence Syndrome (NAS) has become more prevalent in the United States, with the hospitalization rate increasing from 2.9 to 7.3 hospitalizations per 1,000 newborn births between 2009 and 2017. NAS occurs in newborns who experience withdrawal from substances they were exposed to during pregnancy. While NAS is most often associated with exposure to opioids (e.g., Neonatal Opioid Withdrawal Syndrome), it can also be caused by exposure to other drugs such as cocaine, amphetamines, or barbiturates. Infants with NAS experience withdrawal symptoms including tremors, irritability, poor feeding, vomiting, dehydration, and increased sweating. These symptoms usually appear within 72 hours of birth.
