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