It is quite common for men and women who are afflicted with a mental health disorder to also struggle with a co-occurring substance abuse issue. Frankly, it is more widespread than one would think and many men and women currently in alcohol and drug treatment centers in Chualar, California may have mental health issues which are often undiagnosed. Rehab experts at proven alcohol and drug treatment centers in Chualar know how to spot persons with co-occurring psychological and drug and alcohol abuse issues so that both issues can be simultaneously addressed while the person is in treatment. Because both need to be addressed, the person should not leave rehab until they are mentally stable, not just off of drubs.
