The Indiana gubernatorial candidates say the state should do more to attack the abuse of heroin and other drugs. Gregg says the state can see long-term savings by spending on rehabilitation programs rather than sending abusers to jail or prison. Republican candidate Eric Holcomb says drug abuse is strangling many communities and that prevention and treatment programs must be priorities. Republican Eric Holcomb and Democrat John Gregg are set for a final televised debate as they go into the last two weeks of their contentious campaign for the Indiana governor's office.
