It is quite common for men and women who are afflicted with a psychological issue to also have a co-occurring drug and alcohol abuse disorder. Frankly, it is more widespread than one would imagine and a lot of individuals currently in alcohol and drug rehabilitation facilities in San Ysidro, California may have psychological issues which are often undiagnosed. Rehab experts at effective alcohol and drug rehabilitation facilities in San Ysidro know how to identify persons with co-occurring mental health and drug and alcohol abuse issues in hopes that both concerns can be simultaneously addressed while the individual is in rehab. Because both need to be addressed, the client must remain in rehab until they are psychologically stable, not just abstinent.
