Frankly, it is more common than one would assume and quite a few men and women currently in drug rehabilitation facilities in San Bernardino, California may have mental health disorders which are often undiagnosed. Treatment specialists at proven alcohol and drug rehab facilities in San Bernardino know how to identify individuals with co-occurring mental and substance abuse issues so that these two concerns can be simultaneously addressed while the individual is in rehab. Simply because both must be resolved, the person should not leave rehab until they are mentally stable, not just off of drubs.
