It is not uncommon for people who are afflicted with a psychological issue to also be plagued by a co-occurring drug and alcohol abuse issue. Frankly, it is more widespread than one would assume and many men and women currently in drug and alcohol rehab centers in Fall River Mills, California may have mental health disorders which have just simply been undiagnosed. Rehabilitation experts at proven alcohol and drug treatment centers in Fall River Mills know how to identify individuals with co-occurring mental health and alcohol and drug abuse issues in hopes that these two issues can be simultaneously addressed while the person is in rehab. Because both must be resolved, the client must remain in rehab until they are psychologically stable, not just abstinent.
