It is not uncommon for men and women who are afflicted with a mental health disorder to also struggle with a co-occurring drug and alcohol abuse disorder. In fact, it is more widespread than one would imagine and many individuals currently in drug treatment programs in Vallejo, California may have psychological issues which have just simply been undiagnosed. Rehabilitation specialists at successful drug rehabilitation programs in Vallejo know how to identify persons with co-occurring mental and alcohol and drug abuse disorders in hopes that both issues can be handled simultaneously while the person is in rehab. Because both must be resolved, the person should not leave treatment until they are psychologically stable, not just sober.
