Many people in Oregon, Illinois who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who suffer with mental health issues in Oregon, Illinois also become involved in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate in an attempt to alleviate the symptoms of an underlying psychological issue. Some addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug treatment facility is this sort of issue brought to light. This alone can help resolve addiction issues and put the individual in a position to get rehabilitation for both disorders so that they have a good chance of remaining clean and sober and psychologically stable in the future.
