Many people in Columbia, Illinois who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who struggle with mental health issues in Columbia also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychiatric issue. Some treatment clients aren't even diagnosed with a psychological condition, and only when they make it to a drug rehabilitation center 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 good chance of remaining clean and sober and mentally healthy in the future.
