A comprehensive professional mental health and substance use assessment is a thorough evaluation conducted by mental health professionals to understand an individual's mental health status and substance use patterns. The process begins with an intake interview to gather demographic information, understand presenting problems, and collect a detailed history of the present illness. This is followed by a review of the individual’s medical history, including past and current medical conditions, medications, and a detailed substance use history.

Mental health history is also explored, covering previous diagnoses, treatment history, and family history of mental health issues and substance use
