This is where a national pharmacy data base system would come in handy. A person like that would set off warning bells with a system that tracks a persons prescriptions and can tell when someone is scamming the ERs for prescription drugs to sell on the street.
Some provices in Canada have that. It has really cut down on abusers and prescription drug trafficing and abuse.
The trouble with such a database is that government computer and network security is an absolute joke.
