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 to alleviate 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 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 issues off of drugs and mentally stable and happy.
