Persons with co-occurring mental and substance abuse disorders must handle both issues in order to become fully rehabilitated. Some people take drugs to ease symptoms of mental health disorders, and some individuals take drugs which then, in turn, brings about symptoms which are identical to 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 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 alcohol and mentally stable and healthy.
