My guess is that the hospitals and/or doctors were involved in adoption or trafficking. I worked for 43 years on a postpartum/newborn division and mothers were screened for drug testing for: 1) no or less than 3 prenatal visits, 2) history of drug abuse, 3) erratic or violent behavior. Then we carefully reviewed what was given via epidurals, in labor and after delivery. Then, if indicated by the toxicology report, they were referred to a social worker for careful screening. Believe it or not, sometimes the “significant other or friend” actually had slipped something in to their beverage, rare but occasionally. They were then referred, if indicated, to DCFS for follow up.
