MedicalResearch: What is the background for this study? What are the main findings?
Dr. Martins: The background for this study is former studies showing links between nonmedical use of prescription opioids and transition to heroin and other illegal substances, prescription opioid-related and heroin-related fatal overdoses . In addition, a particular public health concern is that the transition to heroin and further injecting heroin may increase the risk of bloodborne infections.
We used data from the National Survey on Drug Use and Health, a large nationally representative household sample of 67,500 people, and self-reported heroin use within the last 12 months, the researchers examined the change in patterns of past-year non-prescription drug and heroin use between 2002-2005 and 2008-2011 across racial and ethnic groups. The most significant rise in heroin use was among Hispanics and non-Hispanic whites, where the rate of
heroin use for the latter group increased by 75 percent in 2008-2011 compared to earlier years. Regarding frequency of use, for Hispanics, increases were significant only among those using opioids about 1-29 days in the past year. Among blacks and whites, significant increases in the rate of heroin use were observed among those using prescription opioids more frequently (100-365 days) in the past year.
