Many individuals in Olney, IL. 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 Olney, Illinois also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to ease the symptoms of an underlying psychiatric disorder. Some addicts aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment facility is this sort of issue brought to light. This in itself can sometimes 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 psychologically stable in the future.
