These days it is harder than ever to get away with doctor shopping because an increasing number of states belong to a national data bank, meaning -- as you have already found out -- that if you fill a prescription in Arkansas and again in California the pharmacy will catch it and can report this to the doctors involved and to the authorities.
You can have more than one doctor. And both can prescribe you medication. What you can't do is lie to your doctors and not tell him what you are getting prescribed elsewhere, in order to get more medication than any one doctor would be willing to prescribe for you. That's doctor shopping, and it is a felony.
If the DA is already alerted to your situation, then not only are you at risk for a felony arrest, so is your doctor. In general, however, the criminal justice
system equates these cases with substance abuse cases. That is, they are likely to offer a defendant felony probation with some kind of drug treatment component, perhaps drug court
, for example, which would give a defendant the possibility of wiping the offense off of his record if he gets his pain management issues in hand and successfully complete the program requirements.
