Persons with co-occurring mental and substance abuse disorders must handle both issues in order to recover completely. Some individuals take drugs to ease symptoms of mental health complications, and some people take drugs which then, in turn, creates symptoms which are identical to mental health disorders, such as depression and anxiety. Drug rehabilitation professionals know how to differentiate between the two, and can work with clients to appropriately treat real mental health disorders 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 mentally stable and happy.
