You aren't familiar with NO are you?
No, I'm not. The more I think about it, the more I see how this could happen. It's just hard to imagine. What to do would depend on many things. How big is the hospital, etc. If they scrambled really fast, they could get all the kids to one floor, lock it off, and let the vermin take what drugs they want. But then again, a hospital in that situation is going to need every ounce of every supply (not just drugs) they have for the emergencies and the sick people that will soon be flooding (no pun intended) it. Sorry about my skepticism. All I can do is pray.
