It is not uncommon for men and women who are afflicted with a psychological issue to also be plagued by a co-occurring substance abuse disorder. In fact, it is more prevalent than one would assume and many men and women currently in drug and alcohol treatment facilities in Anaheim Hills, California may have mental health disorders which have just simply been undiagnosed. Rehabilitation professionals at effective drug rehabilitation facilities in Anaheim Hills know how to identify individuals with co-occurring mental and substance abuse issues so that both issues can be handled simultaneously while the person is in rehab. Simply because both need to be addressed, the individual must remain in rehabilitation until they are psychologically stable, not just off of drubs.
