The program is part of the continuum of care for drug-involved and dual diagnosis adolescents, and includes outpatient, intensive outpatient day treatment, special education day school, and a mental health clinic. MMTC’s residential program has become known for the care of patients with a very high severity of substance use, high rates of emotional/behavioral symptoms, comorbid psychiatric disorders, social and economic deprivation, and significant functional impairment across several psychosocial domains. On admission all patients undergo a comprehensive multidimensional biopsychosocial assessment to determine a level of severity and to confirm appropriateness of placement. The program consists of about 60 patients, mostly boys. Marijuana is the most prevalent drug of abuse. The MMTC approach is a high intensity, 24-hour treatment program that uses a milieu therapy approach drawn heavily from the medical model and therapeutic community elements. The program provides detoxification as one of its treatment services. The 12-step method of facilitation is a central theme. Program elements that are particularly emphasized include psychiatric assessment and treatment, primary care medical assessment and treatment, intensive educational remediation, delinquency/conduct rehabilitation, and family support services. A separate track exists for young adults 18- to 20-years-old. 2 tables, 5 references
