Do you know for sure that she was a "drug baby?" If so, I've lost all sympathy for the late ANS.
My gut is telling me Stern had a huge role in the addiction of both Anna and her son.
I have no idea what the purpose of the methadone prescription was for ANS, but please know that methadone is an extremely common pain medicine for chronic back pain, among other painful ailments. It is long acting and doesn't have the same dosage frequency as other opiates. It is not just utilized to wean addicts off of heroin.
All reports have been that not only did Daniel die from a Methadone overdose (Howard k Stern flused the drugs in the hospital room toilet and called police) but that Anna used Methadone before, during and after her pregnancy.
