I don't understand why pharmacies are the target. People that want Xanax and Adderall for recreational use start with doctor shopping for doctors that will write prescriptions for more than needed, for people that don't need it, etc. So, I could sort of understand identifying doctors that write a disproportionate number of prescriptions for these, or a high ratio of prescriptions for high doses versus more common doses. But the pharmacies? Why? What does that accomplish? Doesn't the person just then go to a different pharmacy?
