Oftentimes, drug and alcohol abuse are closely linked to mental illness. When a dual diagnosis (both a mental disorder and addiction) is present, it is important for drug rehab centers to treat both the drug dependency as well as the underlying cause. Failing to maintain the patient’s mental health long-term will lead to ineffective treatment.
Substance abuse, if not treated, can also lead to the development of new mental disorders in the vicious cycle of dependency. If you or a loved one is struggling with a mental illness or related addiction, seek help from a medical or rehabilitation professional.
