This has already been discussed several times in this thread, but there has been significant effort (& success) to shut down pill mills in the last ~10 years. Opiate Rxs have tapered and are starting to go down, due to 1) increased awareness among the provider community and 2) controlled Rx surveillance programs at the state and national level.
However, the void filled by the decreased supply of prescription opiates has been more than filled by illicit heroin. Not to mention that even with increased provider accountability for narcotic Rxs, there is an equally increased effort to illicitly divert opiates from the healthcare system (i.e. robberies of pharmacies, skilled nursing facilities & elderly communities, organized diversion of opiates from hospital settings, etc).
While there are probably still some holdouts, the healthcare community is painfully aware of the dangers of opiate Rxs and they are dispensed accordingly. We are taught in school that narcotics are to be limited to acute pain (i.e. post surgical) or given chronically to those with terminal disease.
do you have any evidence for this? Physicians are investigated by law enforcement and their respective state medical boards for writing inappropriate opiate prescriptions all the time. There was a case here in Colorado (won't say what specialty or institution) who was busted for writing himself or proxies opiate Rxs so he could take them to get high. Didn't even make it to other people, but the degree of oversight now is such that he had no chance of going undetected.
