This document discusses the issue of high rates of mental illness among incarcerated populations and alternatives to incarceration. It notes that the US currently has more mentally ill people in prisons than ever before, costing $15 billion annually. Treatment options like drug courts and rehabilitation centers are more cost-effective than incarceration. The document also cites studies finding 56% of state prisoners and 64% of jail inmates suffering from mental illness. It raises concerns that releasing these inmates without support may worsen homelessness, recidivism, and public safety issues. Effective treatment of the mentally ill and comorbid could have immeasurable benefits for individual health and community well-being.
