Oklahoma has a shortage of drug treatment programs. People struggling with addiction who can’t afford or access private treatment have limited options — and many turn to unlicensed recovery programs that put them to work for local employers. A new joint investigation by StateImpact and The Frontier found problems at some of these programs — including reports of confiscated disability checks and federal scrutiny for labor practices. This story was co-reported by StateImpact Oklahoma and The Frontier with help from Reveal from the Center for Investigative Reporting as part of a network of local journalists working to investigate work-based rehab programs across the country.
