SAMHSA on Mental Health & Criminal/Juvenile Justice Statistics
Center for Behavioral Health Services & Criminal Justice Research @ Rutgers University (funded by the National Institute of Mental Health)
"Many individuals who come in contact with law enforcement and the criminal or juvenile justice systems have a mental and/or substance use disorder.
"More than 80% of state prisoners, 72% of federal prisoners, and 82% of jail inmates meet the criteria for having either a mental health or substance use issue.
"Studies have found that for youth in the juvenile justice system, 50% to 70% met criteria for a mental disorder and 60% met criteria for a substance use disorder.
"Of those youth with co-occurring mental and substance use issues, almost 30% experienced severe disorders that impaired their ability to function."
