Persons with co-occurring mental and substance abuse disorders must handle both issues if there is any hope for them to recover completely. Some individuals take drugs or alcohol to relieve symptoms of mental health problems, and some people take drugs which then, in turn, brings about symptoms which are identical to mental health problems, such as depression and anxiety. Drug treatment professionals know how to differentiate between the two, and can work with clients to appropriately treat real mental health problems 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.
