Every year, as many as 2,500 Iowa children might be exposed to illegal drugs while still in the womb. Under Iowa law, exposing a child to illicit drugs is considered a form of child abuse and neglect. The law only covers children who are already born.
Between 2003 and 2012, 12,152 children were found to have illicit drugs in their system, information from the Department of Human Services shows.
These databases are part of an IowaWatch story about mothers who abused illicit drugs during pregnancy.
