Persons with co-occurring mental and substance abuse disorders must handle both issues if there is any hope for them to become fully rehabilitated. Some individuals take drugs or alcohol to relieve 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 treatment professionals know how to distinguish between the two, and can work with clients to properly 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 individuals with mental health problems off of drugs and alcohol and mentally stable and productive.
