It is quite common for people who have problems with a psychological issue to also have a co-occurring substance abuse disorder. In truth, it is more widespread than one would think and many men and women currently in alcohol and drug rehabilitation facilities in Big Oak Flat, California may have mental health disorders which are often undiagnosed. Rehab specialists at proven alcohol and drug rehabilitation facilities in Big Oak Flat know how to identify persons with co-occurring mental health and substance abuse disorders so that these two concerns can be handled simultaneously while the individual is in rehab. Because both need to be addressed, the person should not leave rehab until they are psychologically stable, not just off of drubs.
