There is not yet a national database, however some states have a pharmacy watch list, to see to it that you are not double dipping. Case in point, Rush Limbaugh. He was dipping 5 and 6 at a time, and it took his maid turning him in for the DA to find out about it. The Federal Government has tossed the idea around, but have yet to take any action, due to the costs, and privacy rights. This was a topic on all the major networks not to long ago. So I would not be to concerned at this time, maybe in the future, but not yet. Mark
