Persons with co-occurring mental and substance abuse disorders must address both issues in order to recover completely. Some people take drugs or alcohol to ease symptoms of mental health disorders, and some individuals take drugs which then, in turn, brings about symptoms which mimic mental health problems, such as anxiety and depression. Drug treatment professionals know how to differentiate between the two, and can work with clients to correctly 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 disorders off of drugs and mentally stable and happy.
