I'll buy alcohol, but not drugs... From what I read of the AV she appears to have recently been honored for having good grades... I don't think you consistently get good grades with a drug habit...
I'll buy booze as courage or mental defense mechanism... She got drunk to do a disgusting job... If she has had run-ins with CPS before, this may have been her only out...
Personally I see Kim as a scam artist in this deal and the AV as a desperate, misguided, scared woman... But that's just my opinion... I haven't see the AV speak in person yet...

Unfortunately historically African-American college went from being very demanding prior to 1960 to being not very demanding at all post 1970. Good grades at NCCU do not necessarily mean anything.
