LEE COUNTY, Fla. - Pain is big business and legitimate pain clinics are out there to help people who live with pain. But illegitimate clinics - operating on the edge of the law - are causing pain and creating addicts by recklessly prescribing powerful, highly addictive drugs.

At southwest Florida addiction services more and more people are being treated for drug addictions to medications they got with a prescription from pain clinics.

Those clinics are popping up all the time. Ads for retired doctors to run the clinics are even finding their way to Craigslist.

Right now anyone - even a convicted felon can own a pain clinic. But that's about to change and law enforcement says it's about time. A new law takes affect later this year will allow only a physician to open a pain clinic.

There is even a plan to track prescriptions. the effort is to stop people from doctor shopping - going from clinic to clinic getting multiple prescriptions for the same symptom.
