California's drug-treatment diversion law falls short as counties struggle with funding and uneven rollout

California’s Proposition 36, passed two years ago to divert non-violent drug offenders into addiction treatment rather than prison, is not delivering on its promise, according to analysis of the 15 counties with the highest case volumes. Of the 18,666 felony drug cases reported, only 17 % chose the treatment option and a mere 57 defendants had their charges dismissed after graduating. Implementation varies dramatically: San Francisco has made almost no arrests under the law, while Orange County referred 1,311 people but only 314 entered treatment, with fewer than half remaining active and just 15 completing it.

Funding gaps, lack of beds, and insufficient case-manager resources leave many participants, many of whom are homeless, without the shelter and mental-health services promised. Some districts, such as San Diego, report higher enrollment rates, yet statewide data on outcomes remain sparse, and the law may add roughly 1,550 inmates to prisons once fully applied. Lawmakers and advocates argue that the state’s under-funding hampers the program’s effectiveness.
