Drug abuse is often one part of a constellation of issues needing treatment and services. People involved in drug abuse and the criminal justice system have complex needs. A comprehensive assessment is the first step in the treatment process and includes identifying individual strengths to facilitate treatment and recovery. In addition, drug abuse cannot be treated in isolation from related issues and potential threats, such as criminal behavior, mental health status, physical health, family functioning, employment status, homelessness, and HIV/AIDS. These areas must be considered during the initial assessment and incorporated into a treatment plan.
