This week’s final state report on the collapse of Serenity Place in Manchester is more than a cautionary tale of a well-intentioned group that grew too fast. It should be a wake-up call for the governor and council and all involved in the spending of millions upon millions of our tax dollars.

Tom Donovan is the capable head of the state Attorney General’s Charitable Trust Division, which prepared the report on Serenity Place’s downfall. His office has initiated a training process with the Department of Health and Human Services as the New Hampshire Charitable Foundation.

That ought to be mandatory for any group providing treatment service for substance abuse, as pretty much all of them involve public dollars.

Even as our newspaper reported on the issues that brought down Serenity Place, we were reporting on the unveiling of the new plan by the Granite Pathways group to oversee opioid addiction treatment in the state’s two largest cities.

It has a chunk of the $46 million in federal funds the state was recently allocated for its much-ballyhooed “hub and spoke” system. That program holds promise, but the proof of the pudding will lie in results. What checks does the state have that Granite Pathways will not trip up?

Serenity Place developed as one of the initial responses to the opioid tidal wave. It took on too much and too fast without proper expertise.

New Hampshire’s top officials need to make sure that doesn’t happen again.
