It is quite common for people who have problems with a psychological disorder to also struggle with a co-occurring drug and alcohol abuse issue. In truth, it is more prevalent than one would imagine and many people currently in alcohol and drug rehab facilities in San Anselmo, California may have psychological issues which have just simply been undiagnosed. Rehabilitation specialists at proven drug rehab programs in San Anselmo know how to identify persons with co-occurring psychological and drug and alcohol abuse disorders so that these two concerns can be handled simultaneously while the person is in rehab. Simply because both must be resolved, the individual must remain in treatment until they are psychologically stable, not just abstinent.
