William E. Hurwitz, M.D., was a Virginia based pain management physician who was prosecuted and convicted by the United States Government in 2004 for excessively prescribing addictive opioid pain medication to patients, some of whom subsequently abused and redistributed their medications on the black market. Before his conviction, Hurwitz had a series of running battles with the Virginia Board of Medicine which, in 2003 found fault with some of his prescriptions but also held that all were written "in good faith".
