Many individuals in Centralia, Illinois who find their way to 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 Centralia also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate in an attempt to alleviate the symptoms of an underlying psychiatric disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment facility is this sort of psychological condition brought to light. This alone can sometimes help resolve addiction issues and put the individual in a position to get rehabilitation for both conditions so that they have a good chance of remaining clean and sober and psychologically healthy in the future.
