Peter Day's World of Business

Ohio is one of the worst hit US states for opioid addiction rates and deaths. Huge numbers of people have dropped out of the workforce and employers say they struggle to recruit the people they need.

For them, the opioid crisis might just be a very profitable business opportunity. Producer: Rosamund Jones
