In truth, it is more prevalent than one would assume and a lot of individuals currently in drug and alcohol treatment centers in Benicia, California may have psychological disorders which have just simply been undiagnosed. Treatment experts at effective drug rehab facilities in Benicia know how to identify individuals with co-occurring psychological and substance abuse issues in hopes that these two concerns can be simultaneously addressed while the individual is in rehabilitation. Because both need to be addressed, the person should not leave rehab until they are mentally stable, not just off of drubs.
