An audit by the Oregon Secretary of State's office has delivered a damning verdict on the state's implementation of Measure 110, the landmark 2020 ballot initiative that decriminalized possession of small amounts of drugs and redirected cannabis tax revenue toward treatment. The audit found that Oregon has dedicated approximately $800 million in cannabis tax dollars and other funding to Measure 110 programs — but cannot answer fundamental questions about how many people have been served or whether outcomes have improved. Demographic data such as race, ethnicity, age, and gender is often missing or inconsistent, making it impossible to determine whether funding is reaching communities most harmed by the war on drugs.

The audit's central finding — "a lopsided implementation" — reflects a systemic failure. Law enforcement lost tools to engage with people possessing small amounts of drugs, while no established treatment system existed to catch them. Inside OHA, leadership changes, reorganizations, and unclear accountability weakened the program from day one. The Legislature compounded the chaos by amending Measure 110 nearly every year since passage, making it impossible for OHA to build or evaluate long-term strategies. In 2024, legislators recriminalized possession of smaller drug amounts via House Bill 4002, further destabilizing the policy framework. Service data may even double-count individuals across different program categories, the audit found.

For Oregon's behavioral health providers and CCOs, the audit raises urgent questions about accountability and sustainability. The Behavioral Health Resource Network — Measure 110's primary service delivery mechanism — has operated without reliable outcome data for five years. Providers cannot demonstrate effectiveness, funders cannot justify allocations, and communities cannot assess whether the $800 million investment has reduced harm. OHA agreed with only three of six audit recommendations, pushing back on evaluating Measure 110's impact on overdose rates by citing fentanyl's arrival as confounding any valid comparison.

Watch for OHA's November 2026 deadline: all Measure 110 grantees will be required to submit data through two new systems that integrate with electronic health records. Whether these systems produce meaningful accountability — or become another reporting burden without insight — will determine whether Oregon can salvage its boldest drug policy experiment. The Legislature's appetite for further reforms in the 2027 session will depend heavily on whether that data finally tells a coherent story.
