ATLANTA, March 3 (UPI) -- Those at highest overdose risk from prescription painkillers -- opioids -- most likely get them from a doctor, U.S. health officials say.
Researchers at the Centers for Disease Control and Prevention analyzed data from 2008 through 2011 from the Substance Abuse and Mental Health Services Administration's National Survey on Drug Use and Health involving those who use prescription painkillers non-medically -- those who use the medications without a prescription, or use the drugs for their "high."
