Because most medicines and drugs pass through a mother's placenta to her unborn baby, a mother's illegal drug use during pregnancy can cause the child to suffer from neonatal abstinence syndrome (NAS). The Centers for Disease Control and Prevention (CDC) reports that, "according to 2016 data from the Healthcare Cost and Utilization Project … seven newborns were diagnosed with NAS for every 1,000 newborn hospital stays. That is approximately one baby diagnosed with NAS every 19 minutes in the United States, or nearly 80 newborns diagnosed every day."
