Many addicted individuals in Milan, Illinois 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 Milan, Illinois 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 relieve 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 rehabilitation center is this sort of issue brought to light. This in itself can help resolve addiction issues and put the person in a position to get rehabilitation for both disorders so that they have a strong chance of remaining abstinent and psychologically stable in the future.
