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 problems, and some individuals take drugs which then, in turn, causes symptoms which are identical to mental health issues, such as depression and anxiety. Drug rehabilitation professionals know how to distinguish between the two, and can work with clients to properly 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.
