I measured the role of opioid analgesics in drug abuse-related deaths in a consistent panel of 28 metropolitan areas from the Drug Abuse Warning Network. The number of reports of opioid analgesics increased 96.6% from 1997 to 2002; methadone, oxycodone, and unspecified opioid analgesics accounted for 74.3% of the increase. Oxycodone reports increased 727.8% (from 72 to 596 reports). By 2002, opioid analgesics were noted more frequently than were heroin or cocaine. Dramatic increases in the availability of such opioids have made their abuse a major, growing problem.
