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 or alcohol to relieve symptoms of mental health disorders, and some people take drugs which then, in turn, brings about symptoms which mimic mental health issues, such as depression and anxiety. Drug treatment professionals know how to distinguish 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 person. This has proven to be effective in keeping individuals with mental health problems off of drugs and mentally stable and happy.
