Many people in Harviell, Missouri who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who struggle with mental health issues in Harviell 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 alleviate the symptoms of an underlying psychological condition. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation center is this sort of issue uncovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to get rehabilitation for both disorders so that they have a strong chance of remaining abstinent and psychologically healthy in the future.
