You can use ePrescribe with Schedule II and Schedule IV and V, although I don't know where they are with the logistics. I think of it as weddings for DEA. The saying for weddings is:
Something borrowed Something new Something old, and Something blue
while the DEA wants:
Something you have Something you are Something you know
Absolutely stupid, given ePrescribe is likely the safest way to prescribe. Just give us a password or one of those little things that change passwords every eight seconds. Please.
