This was researched before and as a lawyer and this was the topice of discussion way back when this started. Doctor shopping is as rare as unicorns.

This is from a quick Google search -- it's not exhaustive:
From an August 1, 2003 Message from Attorney General Charlie Crist (about stopping prescription drug abuse and doctor shopping) --
"This comes on top of another success in the area of prescription drug fraud, when the Office of Statewide Prosecution worked with law enforcement to arrest 19 individuals on charges of adulterating prescription medication. The arrests followed indictments by a Fort Lauderdale grand jury last week."

From a 2001 St. Lucie County sheriff's report --

From a Florida LE report (more detail on the incident above) --
"In July, 24 people were arrested as part of a drug sting in St. Lucie County, where law enforcement and pharmacies cooperated to disrupt an informal distribution network. Most of the 24 who were arrested were once legitimately ill or disabled and living off Social Security or veteran’s benefits that enabled them to get prescriptions."

Florida started cracking down on Oxycontin abuse long before Rush was caught up in it. Now where's your cite that Florida doctor shopping prosecutions are as rare as unicorns?
