Many people in Oquawka, Illinois 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 Oquawka, Illinois also become involved in substance abuse at some time in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to relieve the symptoms of an underlying psychiatric disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehab facility is this sort of psychological condition uncovered. This in itself can help resolve addiction issues and put the person in a position to receive treatment for both conditions so that they have a good chance of remaining abstinent and mentally healthy in the future.
