It is not uncommon for people who have problems with a psychological issue to also be plagued by a co-occurring alcohol and drug abuse disorder. Frankly, it is more widespread than one would think and a lot of individuals currently in drug and alcohol rehab facilities in Plymouth may have psychological issues which have just simply been undiagnosed. Treatment professionals at proven alcohol and drug rehab facilities in Plymouth know how to spot persons with co-occurring psychological and substance abuse disorders in hopes that these two concerns can be handled simultaneously while the individual is in treatment. Because both must be resolved, the individual should not leave rehab until they are mentally stable, not just sober.
