This day and time we all know you have to show identification to purchase certain types of cold meds. Your name goes on a list with other names to be checked. What I want to know is what agency checks these list? If you know for a fact its local law enforcement than this doesn't help me at all. I'm trying to figure out if its government controlled, DEA, some kind of special dept. or what. I really need this info to help someone. This person is not abusing the system but could be helped by what ever agency over sees the process. The pharmacy will not give up the info, but I only tried calling one pharmacy.
