Many people in Stone Park, 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 Stone Park 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 ease the symptoms of an underlying psychological condition. Some addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug rehabilitation center is this sort of issue brought to light. This alone can sometimes help resolve addiction issues and put the person in a position to receive rehabilitation for both disorders so that they have a strong chance of remaining abstinent and psychologically stable in the future.
