The Untreated Condition That Drives Relapse

One of the most important and least understood facts about addiction is how deeply it is connected to mental health. SAMHSA's research consistently shows that more than 50% of people with a substance use disorder also have a co-occurring mental health condition, what clinicians call a dual diagnosis. Depression, anxiety, PTSD, bipolar disorder, and untreated trauma are not separate problems from addiction. They are, for many people, the source of it.

When families understand this connection, everything about their loved one's behavior starts to make more sense. The substance use is often not the primary problem, it is the solution their loved one found for a problem that was there first. Numbing anxiety. Quieting trauma. Managing depression. Escaping a pain that no one ever addressed. This doesn't excuse the addiction or make treatment less urgent. It makes treatment more complete, because treating addiction without addressing the underlying mental health condition is one of the leading causes of relapse.

According to the National Alliance on Mental Illness (NAMI), 1 in 5 American adults experience a mental illness each year. The National Institute of Mental Health (NIMH) reports that mental health conditions are the leading cause of disability in the United States. And yet stigma, confusion, and a lack of integrated care mean that the majority of people with both addiction and mental health conditions receive treatment for neither, or only one. This section exists to change that, one family at a time.

Why Mental Health and Addiction Must Be Treated Together

Historically, mental health treatment and addiction treatment existed as separate systems, a person would go to a psychiatric facility for one and an addiction treatment center for the other, at different times, with different providers who rarely communicated. This separation was clinically catastrophic. Treating addiction without addressing the underlying depression or trauma left the root cause intact. Treating the psychiatric condition without addressing the substance use meant the substance continued to undermine treatment.

The evidence is now clear: integrated dual diagnosis treatment, addressing both conditions simultaneously, within the same treatment episode, by a team that understands both, produces significantly better outcomes than treating either condition alone. SAMHSA, NIDA, and ASAM all support integrated care as the evidence-based standard for co-occurring disorders.

When a family member asks "why does my loved one keep relapsing even when they commit to sobriety?", the answer is often untreated mental health. When they ask "why does my loved one's depression never get better?", the answer is often continued substance use. These are not separate problems. They are one problem that requires one integrated solution.
