Many people in Nauvoo, Alabama who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who suffer with mental health issues in Nauvoo also become involved in substance abuse at some point in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate in an attempt to ease the symptoms of an underlying psychiatric condition. Some addicts aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation program is this sort of issue discovered. This in itself can help resolve addiction issues and put the individual in a position to get treatment for both disorders so that they have a good chance of remaining clean and sober and mentally stable in the future.
