Substance Abuse Services: Substance abuse services, including both assessments and treatment, are offered throughout the programs of the Tidewater Youth Services Commission. Assessments are provided by a Certified Substance Abuse Counselor (CSAC). The evaluation includes interviews with the youth and parent/guardian, completion of the Substance Abuse Subtle Screening Inventory (SASSI), the Adolescent Problem Severity Index (APSI), and Urine Drug Screen (UDS). All drug screens receive a medical confirmation and strict chain-of-custody procedures are followed. The Commission uses LabCorp, a Substance Abuse and Mental Health Services Administration (SAMHSA) approved testing laboratory. Treatment/counseling services may be provided individually, in a group setting (Tidewater Juvenile Substance Abuse Program), or both.
