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