It is quite common for people who struggle with a mental health disorder to also struggle with a co-occurring alcohol and drug abuse disorder. Frankly, it is more common than one would assume and quite a few men and women currently in drug rehab facilities in Taylorsville, California may have mental health issues which have just simply been undiagnosed. Rehab experts at effective drug rehab centers in Taylorsville know how to identify individuals with co-occurring psychological and alcohol and drug abuse issues so that these two issues can be handled simultaneously while the person is in treatment. Because both must be resolved, the individual must remain in treatment until they are mentally stable, not just abstinent.
