DENVER – A new report released Thursday that studies heroin use in Colorado shows a huge spike in heroin seizures and hepatitis C transmissions among young users in the state.

The report, “Heroin in Colorado,” was compiled by a wide array of public health, drug enforcement and other officials and prepared by the Heroin Response Work Group. It's the first of its kind in Colorado.

It is broken down into seizure and arrest data, overdose data, data on Naloxone use, disease transmission data, neonatal data, exposure calls and other treatment and user information.

Pueblo County has the highest age-adjusted death rate due to heroin, and southern Colorado has higher rates than the rest of the state.

Some of the data was also released in January in the Substance Abuse Trend and Response Task Force’s 11th-annual report.

“Too many Colorado families have been hurt by the heroin epidemic,” said Lt. Gov. and Chief Operating Officer Donna Lynne. “This first-ever report provides the sobering statistics and serves as our call to action to do all we can to help our citizens avoid its use and provide support to those on the front lines of battling its misuse.”

“People are dying from opioid overdoses at an alarming rate across the country and here in Colorado,” said Colorado Attorney General Cynthia Coffman. “Every one of the people we lose to an overdose is somebody’s loved one and their addiction and subsequent death not only impacts them and their families, it affects our community as a whole. Colorado must be proactive in tackling this heroin crisis, and this report provides us with comprehensive data that can help us to focus our state’s resources where they are most needed. My office will continue to work collaboratively with stakeholders to combat this growing issue.”
