Persons with co-occurring mental and substance abuse disorders must handle both issues in order to recover completely. Some individuals take drugs or alcohol to ease symptoms of mental health disorders, and some people take drugs which then, in turn, brings about symptoms which are identical to mental health disorders, such as anxiety and depression. Drug rehabilitation professionals know how to distinguish between the two, and can work with clients to appropriately treat real mental health disorders in tandem with any other substance abuse treatment that is done with the person. This has proven to be effective in keeping people with mental health issues off of drugs and alcohol and mentally stable and happy.
