No info for how much Oregon spends on other illnesses such as cancer, Alzheimer's, heart disease.  Of course any comparison would be skewed by the fact that due to the IMD exclusion mental illness is the only illness that is discriminated against by the Federal government.  The Medicaid Institutions for Mental Disease (IMD) exclusion is an outdated, discriminatory federal rule that creates significant barriers to treatment for adults with severe mental illness.  Under this rule Medicaid payments to states are prohibited for non-geriatric adults receiving psychiatric care in a treatment facility with more than 16 beds.  Even with recent advances in mental health care afforded by the ACA and federal parity legislation the IMD exclusion remains the only section of federal Medicaid law that prohibits federal payment for medically necessary care simply because of the type of illness being treated.  This discriminatory rule is a leading cause of the shortage of beds for those most in need.
