Many individuals in Harlan, IA. 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 struggle with mental health issues in Harlan, Iowa also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychological disorder. Some addicts 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 brought to light. This in itself can help resolve addiction issues and put the person in a position to receive treatment for both conditions so that they have a good chance of remaining abstinent and mentally stable in the future.
