Persons with co-occurring mental and substance abuse disorders must handle both issues in order to recover completely. Some individuals take drugs or alcohol to alleviate symptoms of mental health disorders, and some individuals take drugs which then, in turn, brings about symptoms which are identical to mental health issues, such as depression and anxiety. Drug rehabilitation professionals know how to differentiate between the two, and can work with clients to properly 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 healthy.
