It is not uncommon for men and women who are afflicted with a psychological disorder to also be plagued by a co-occurring alcohol and drug abuse disorder. In truth, it is more widespread than one would assume and many men and women presently in alcohol and drug rehabilitation centers in Colusa, California may have psychological disorders which are often undiagnosed. Rehab professionals at successful drug treatment programs in Colusa know how to spot persons with co-occurring psychological and substance abuse issues so that these two issues can be simultaneously addressed while the person is in rehabilitation. Because both need to be addressed, the individual should not leave treatment until they are psychologically stable, not just off of drubs.
