It is not uncommon for individuals who have problems with a psychological disorder to also have a co-occurring alcohol and drug abuse disorder. In fact, it is more common than one would think and many men and women currently in drug treatment centers in Fullerton, California may have mental health disorders which are often undiagnosed. Rehab specialists at successful alcohol and drug treatment centers in Fullerton know how to identify individuals with co-occurring mental and drug and alcohol abuse issues in hopes that these two concerns can be simultaneously addressed while the individual is in rehab. Simply because both need to be addressed, the individual should not leave rehabilitation until they are psychologically stable, not just off of drubs.
