After a recent surgery my mom was able to pick up an opiate painkiller from the hospital pharmacy for me (she was my driver). They told her to take *MY* ID (she held all of my belongings) but not her own (I did authorize the hospital to talk to her about my condition, but apparently that was not necessary for her to pick up a controlled substance on my behalf).

When I was married, my then husband was able to pick up a controlled substance on my behalf. I did not give any formal permission, but he had to show HIS id (matching super common last name but not address, because when you move our state just gives you a piece of paper with the new address). I don't know if they recorded his id; they didn't record mine when I picked it up.
