Does rehab work? What the evidence says

The evidence

Yes, treatment works. Addiction treatment reduces substance use by 50-70%, reduces criminal activity by 80%, and improves employment by 40%. These are comparable to treatment outcomes for other chronic conditions like diabetes and hypertension.

Defining success

If success means one episode of treatment producing permanent abstinence, rates are modest (30-40%). If success means significant reduction in use, improved health, and better functioning over time (the appropriate comparison for a chronic condition), rates are much higher (60-70%).

What predicts better outcomes

Longer treatment duration. Engagement in aftercare. MAT when indicated. Treatment of co-occurring conditions. Stable housing. Employment. Recovery community involvement. Family support.

The chronic disease framework

Addiction is a chronic condition, not an acute illness. Like diabetes, it requires ongoing management. Relapse is a treatment complication, not treatment failure. Multiple treatment episodes may be needed. Long-term engagement produces the best outcomes.
