Dual diagnosis means two conditions at once. A mental health disorder and a substance use disorder, happening together. This is common. In fact, it is the norm in addiction treatment, not the exception.

Depression, anxiety, PTSD, and other conditions often show up alongside drinking or drug use. One can feed the other. That is why treating just one rarely holds.

Dual diagnosis care addresses both at the same time. You get support for your mental health and your recovery together.
