Indiana prohibited needle exchanges when the outbreak began primarily among intravenous drug users. But lawmakers passed a law in 2015 allowing the exchange programs with state approval.
Republican Gov. Eric Holcomb wants to roll back that law. He says local officials should be able to approve the exchanges.
Needle exchanges provide intravenous drug users with clean syringes and collect used ones to reduce needle-sharing and the spread of HIV, hepatitis C and other diseases.
