I said the first thing they do is collect the morphine. You are confirming that fact. What they do with it varies, of course. The reason they collect it so fast is it’s so dangerous.... it can and does kill.
I misunderstood you. But the reason they get rid of it is not for your more nefarious reasons. It’s because it’s a controlled substance and can’t be left around when the person it’s issued to is gone.
