When somebody is classified with a dual diagnosis it means that they have a substance abuse problem along with another mental health issues such as; depression, anxiety, schizophrenia, or bipolar disorder. The fact of having both of these conditions makes treatment more complicated and both issues will need to be dealt with if there is to be any chance of a successful recovery. Dual diagnosis drug rehabilitation is now more widely available than ever before so this means that there is more hope for the person in this position.
