Persons with co-occurring mental and substance abuse disorders must address both issues if there is any hope for them to recover completely. Some people take drugs or alcohol to relieve symptoms of mental health complications, and some people take drugs which then, in turn, brings about symptoms which mimic mental health issues, such as anxiety and depression. Drug treatment professionals know how to distinguish between the two, and can work with clients to appropriately treat real mental health problems in tandem with any other substance abuse treatment that is done with the individual. This has proven to be effective in keeping people with mental health issues off of drugs and alcohol and mentally stable and healthy.
