Many individuals in Central City 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 struggle with mental health issues in Central City also become involved in substance abuse at some time in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate in an attempt to relieve the symptoms of an underlying psychiatric issue. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab facility is this sort of psychological condition uncovered. This alone can help resolve addiction issues and put the person in a position to receive rehabilitation for both conditions so that they have a strong chance of remaining abstinent and psychologically healthy in the future.
