High levels of Controlled Prescription Drug (CPD) abuse are contributing to increased heroin use.
Increased demand for, and use of, heroin is being driven by both increasing availability of heroin in the U.S. market and by some controlled prescription drug (CPD) abusers using heroin. After the 2010 reformulation of the commonly abused prescription opioid OxyContin®, which made it difficult to inhale or inject, some people who abused OxyContin® migrated to heroin for access to a potent injectable drug. This phenomenon is contributing to the increase in heroin use in the United States.
Like much of the nation, Wisconsin continues to battle a heroin and opiate epidemic. Milwaukee County alone has seen a 495% increase in heroin related deaths between 2005 - 2014. The Milwaukee County medical examiner's office reported that a record high 255 people died in Milwaukee County of drug overdoses in 2015, an increase of 53% from 2012.
