Many addicted individuals in Paris, Illinois who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who suffer with mental health issues in Paris, Illinois also take part in substance abuse at some point in their lives. These dual diagnosis clients typically turn to drugs or alcohol to self medicate as a way to alleviate the symptoms of an underlying psychiatric disorder. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation program is this sort of issue discovered. This alone can help resolve addiction issues and put the individual in a position to get treatment for both conditions so that they have a good chance of remaining abstinent and psychologically healthy in the future.
