Many addicted individuals in Yetter, Iowa who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who suffer with mental health issues in Yetter also become involved in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate in an attempt to alleviate the symptoms of an underlying psychological issue. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug rehabilitation center is this sort of psychological condition discovered. This in itself can help resolve addiction issues and put the individual in a position to receive rehabilitation for both disorders so that they have a good chance of remaining abstinent and psychologically healthy in the future.
