A new report from CDC's National Center for Health Statistics shows that nearly 7% of adults reported using a prescription opioid analgesic in the past month in 2011-12. Use of opioid analgesics increased from 5% to 6.9% between 199902 and 200306, and the rate has remained stable since then. CDC also reports that the percentage of opioid analgesic users who used a drug stronger than morphine more than doubled during the study period, from 17% to 37%. Meanwhile, the percentage of adults who used only a weaker-than-morphine opioid analgesic declined from 42.4% to 20%. More women than men used opioid analgesics between 2007 and 2012, with 7.2% of women and 6.3% of men. In addition, adults aged 40 years and older were more likely to use opioid analgesics than adults aged 20 to 39 years, while women aged 60 years and older were more likely to use the drugs than men in the same age group.
