It is not uncommon for men and women who are afflicted with a mental health issue to also struggle with a co-occurring substance abuse disorder. In truth, it is more prevalent than one would assume and quite a few men and women currently in drug rehabilitation centers in Calimesa, California may have mental health disorders which are often undiagnosed. Rehabilitation experts at successful drug and alcohol rehabilitation programs in Calimesa know how to identify individuals with co-occurring mental and alcohol and drug abuse issues in hopes that both issues can be simultaneously addressed while the person is in rehabilitation. Because both need to be addressed, the person must remain in rehab until they are psychologically stable, not just sober.
