It is not uncommon for men and women who have problems with a psychological disorder to also have a co-occurring substance abuse disorder. In truth, it is more common than one would imagine and a lot of individuals currently in drug and alcohol rehabilitation facilities in San Pablo, California may have mental health issues which have just simply been undiagnosed. Rehab professionals at effective drug rehab programs in San Pablo know how to identify individuals with co-occurring mental and alcohol and drug abuse issues in hopes that these two issues can be handled simultaneously while the individual is in rehab. Simply because both need to be addressed, the person should not leave treatment until they are mentally stable, not just off of drubs.
