Many addicted individuals in Hanlontown, 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 Hanlontown 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 as a way to ease the symptoms of an underlying psychological disorder. Some addicts aren't even diagnosed with a disorder, and only when they make it to a drug treatment center is this sort of psychological condition uncovered. This alone can sometimes help resolve addiction issues and put the person in a position to receive treatment for both disorders so that they have a good chance of remaining abstinent and psychologically healthy in the future.
