Hey people I feel your pain. Ha, Ha I am a pain doc.
Just be happy e-precribe works for non-controlled drugs. As far as controlled meds there are many more DIFFERENT federal vs state laws, some trump the other and some are more stringent than the other. Usually the tougher law wins. Then each state has a pharmacy board which can get their feelings hurt when a law is changed and no one asked them. Even more stupid they can influence e-prescribe laws b/c they are concerned that there are some little mom and pop pharmacies that don't have a computer. ( here in Georgia they actually said that !)
It is a lot more complicated than just point verification. Hey there are drug dealers out there that are pretty good a computer stuff.
Don't look at these issues as a pain in the ---, look at them as the government is really trying to keep prescribed narcotics off your local playground. But, remember how long and inefficiently it takes any government agency to do the right thing.
