I have a Pharmacist who attends my Group Thearapy Sessions. He said the enforcement of the Anti-Doctor-Shopping Lawa accelerated after the Michael Jackson Death. They are requiring a National Perscription Database that Doctors must check for duplicate perscriptions from other Doctors prior to writing a perscription. The Pharmacy can check and flag suspecious activity too. The technical aspects of the system haven't been implimented Nationwide yet but it's coming. The days of going to six different Pain Clinics to score a couple of hundred Oxycontin are going to be over.
