Persons with co-occurring mental and substance abuse disorders must address both issues if there is any hope for them to recover completely. Some individuals take drugs or alcohol to alleviate symptoms of mental health disorders, and some people take drugs which then, in turn, causes symptoms which mimic mental health problems, such as anxiety and depression. Addiction treatment professionals know how to distinguish between the two, and can work with clients to correctly 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 individuals with mental health disorders off of drugs and mentally stable and happy.
