More Rehab Centers, But Overdoses Rose in One California Region

The development

One California region saw overdoses move in the opposite direction from what many would expect as rehabilitation centers became more common. Instead of falling, overdoses increased.

What the comparison shows

The development raises a basic public-health question: why did a larger network of rehabilitation centers not produce fewer overdoses in that region? The answer cannot be reduced to the number of facilities alone. Treatment availability, whether people can enter care, and what happens after treatment may all matter, but the region, dates and numbers are not established here.

What remains to be established

A clear account would need to identify the California region, measure the change in rehabilitation capacity, and compare it with overdose data over the same period. It would also need to distinguish between overdose deaths and other overdose measures.

The central point is narrower: more rehabilitation centers and fewer overdoses did not occur together in the region described. That finding does not show that rehabilitation centers are ineffective, but it does show that counting facilities alone cannot demonstrate that overdose risks are falling.
