What is a common mental health disorder often seen alongside substance use disorders?

Depression is a common mental health disorder frequently observed in individuals with substance use disorders. The relationship between depression and substance use is complex; individuals may use substances as a way to cope with depressive symptoms, while substance use can also exacerbate feelings of sadness and hopelessness. This dual diagnosis can significantly complicate treatment, as each disorder can influence the course and management of the other.

In clinical practice, recognizing the presence of depression in clients with substance use disorders is essential for developing effective treatment plans. Addressing both conditions simultaneously—often referred to as integrated treatment—can improve outcomes for individuals facing these co-occurring disorders.

Other disorders listed, such as schizophrenia, personality disorders, and anxiety disorders, can also co-occur with substance use disorders but are not as commonly associated as depression. While they certainly require attention, the prevalence and clear link between depression and substance use make depression the most relevant answer in this context.
