It is not uncommon for men and women who are afflicted with a mental health disorder to also be plagued by a co-occurring alcohol and drug abuse disorder. Frankly, it is more common than one would assume and many men and women currently in alcohol and drug rehab centers in Gwynedd may have psychological disorders which are often undiagnosed. Rehabilitation experts at successful drug and alcohol rehabilitation programs in Gwynedd know how to identify persons with co-occurring mental health and substance abuse issues in hopes that these two concerns can be simultaneously addressed while the person is in rehabilitation. Simply because both need to be addressed, the individual should not leave treatment until they are mentally stable, not just sober.
