Researchers at Columbia University’s Mailman School of Public Health looked at the frequency of nonmedical prescription opioid use and the risk of heroin-related behaviors and found that past-year heroin use rose among individuals taking opioids like OxyContin and these increases varied by race and ethnicity.

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% in 2008-2011 compared to earlier years. Findings are online in the journal Drug and Alcohol Dependence.
