We acknowledge that clients wishing to enter our treatment program often have both substance use and mental health treatment needs (co-occurring disorders). We welcome these clients and are fully committed to offering appropriate assistance for each client, including you. “Co-occurring Disorder” is defined as having at least one mental condition as well as a drug use disorder. While these conditions may interact differently in any one person (e.g., an episode of depression may trigger relapse into alcohol abuse, or cocaine use may intensify schizophrenic symptoms), at least one disorder of each type can be diagnosed independently of the other. Other terms used to describe this disorder are comorbidity and dual diagnosis.
