A Secretary of State audit found that after four years and roughly $800 million, OHA cannot determine whether Measure 110 reduced overdoses or expanded treatment. OPB reported the agency cannot answer basic questions about how many people received services.

The Legislature recriminalized drug possession in 2024 after public backlash. The audit found inconsistent data collection, no standardized metrics, and limited oversight. OHA now requires grantees to submit data through two new integrated data systems by November 2026.

Washington State has cited Oregon's experience in retreating from decriminalization. Measure 110's perceived failure has reshaped the national conversation around harm reduction.

Watch for: The November 2026 deadline — the last credible opportunity to demonstrate impact before the 2027 session. Oregon's experience will factor into the national reckoning over whether decriminalization-plus-treatment models can work at scale.
