It is not uncommon for individuals who struggle with a mental health issue to also be plagued by a co-occurring alcohol and drug abuse disorder. Frankly, it is more common than one would think and quite a few people currently in drug and alcohol rehab centers in Alhambra, California may have mental health issues which are often undiagnosed. Treatment experts at effective drug rehabilitation facilities in Alhambra know how to identify persons with co-occurring mental and substance abuse disorders so that both issues can be simultaneously addressed while the person is in rehab. Because both must be resolved, the individual must remain in rehabilitation until they are psychologically stable, not just off of drubs.
