Panel 1: Comorbidity: when a person has two or more disorders at the same time or one after the other. This occurs frequently with substance use and mental disorders. Comorbidity also means that interactions between these two disorders can worsen the course of both.
Panel 2: Who is affected?
- 7.7 million adults have co-occurring mental and substance use disorders. This doesn’t mean that one caused the other and it can be difficult to determine which came first.
- Of the 20.3 million adults with substance use disorders, 37.9% also had mental illnesses.
- Among the 42.1 million adults with mental illness, 18.2% also had substance use disorders.
Panel 3: Who gets treatment?

- 3.9% of those with co-occurring conditions received substance use treatment only.
