OxyContin is an opioid painkiller whose abuse and overprescribing have fueled addiction crises and regulatory scrutiny.
Federal filings show a nurse practitioner prescribed hundreds of thousands of opioid pills across more than 20 states, guiding clients on evading DEA scrutiny. The DEA has revoked her authority to prescribe controlled substances. Civil settlement reached earlier this year did not admit wrongdoing. Details tie prominent athletes and others to the operation.
