It is not uncommon for men and women who struggle with a psychological issue to also struggle with a co-occurring alcohol and drug abuse disorder. In fact, it is more prevalent than one would think and quite a few men and women presently in alcohol and drug treatment facilities in Arcata, California may have mental health issues which are often undiagnosed. Treatment specialists at effective drug and alcohol rehab programs in Arcata know how to spot persons with co-occurring mental and alcohol and drug abuse disorders in hopes that these two concerns can be simultaneously addressed while the individual is in treatment. Because both need to be addressed, the person should not leave rehab until they are psychologically stable, not just sober.
