That's silly. 99% of the time, a drug addict is not fit to be a parent. Depending on the drug, even breastfeeding the baby will cause it to OD. It's perfectly reasonable to get child services involved if the mother tests positive for illicit drugs.
Now, what's ridiculous is getting child services involved because a patient tested positive to a drug you gave them, unless there's other obvious signs of drug abuse.
Yes, I do.
