Name one common co-occurring disorder with substance use disorders.

Major depressive disorder is commonly recognized as a co-occurring disorder with substance use disorders. This association is significant because individuals with substance use issues may turn to drugs or alcohol as a way to cope with or self-medicate their depressive symptoms. Conversely, the effects of substance use can exacerbate or trigger depressive episodes. The interplay between substance use and major depressive disorder presents a complex challenge for treatment, as both conditions require integrated and comprehensive approaches to effectively address the individual's mental health and substance use issues simultaneously.

In the context of the other disorders listed, while they can also co-occur with substance use disorders, they are less frequently seen in conjunction compared to major depressive disorder. Schizophrenia may lead to substance use in some cases but is not as prevalent in co-occurrence norms. Obsessive-compulsive disorder, while it can interact with substance use, generally does not occur as frequently as major depressive disorder. Autism spectrum disorder might present unique challenges but does not have the same strong correlation with substance use disorders as major depressive disorder does.
