There is general agreement that the “principle of balance” should guide controlled substance policy and regulation in the United States. Although the diversion of controlled substances from medical to nonmedical purposes is a significant public health problem, overly aggressive controlled substance regulation has been shown to have an unintended deterrent effect on appropriate controlled substance use, including pain management with opioid analgesics. The promotion of effective pain management and the reduction of substance abuse are equally important regulatory objectives. Neither regulatory (...) objective need be sacrificed to achieve the other. Rather, the two objectives must be balanced with each other to assure that necessary pain management is encouraged while drug abuse is curtailed.Approximately 75 million people in the United States suffer from severe pain. Fifty million of these suffer chronic pain, and 25 million suffer acute pain from trauma or surgery. Pain is not merely an uncomfortable symptom. (shrink)
