Many rehab programs in Chandler Heights, Arizona address individuals with co-occurring mental and substance abuse disorders. A client who struggles with a mental disorder(s) and substance abuse needs to work through both issues concurrently. Failing to handle the client's mental disorder(s) during their drug treatment will leave them susceptible to relapse once they leave treatment. Problems with mood disorders, anxiety disorders and other mental disorders (schizophrenia, personality disorders, etc.) will surface once back in their day to day life. If the client does not have a handle on how to handle their mental disorder they will likely fall back into their old ways of abusing drugs or alcohol as a means of coping and self-medicating.
