Unconsumed opioids pose a diversion risk. In the 2011 National Survey on Drug Use and Health, 70.8% of those who used a prescription medication non-medically obtained the medication from a friend or relative, with or without their knowledge. Additionally, nonmedical prescription opioid use is a common pathway to heroin use. Importantly, over 80% of young intravenous drug users report initiation of prescription opioid misuse prior to heroin.
