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 problems, and some individuals take drugs which then, in turn, creates symptoms which are identical to mental health disorders, such as anxiety and depression. Drug treatment professionals know how to distinguish between the two, and can work with clients to appropriately treat real mental health conditions 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 mentally stable and productive.
