Many people in East Peoria, 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 East Peoria also become involved in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate as a way to relieve the symptoms of an underlying psychiatric issue. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab center is this sort of issue uncovered. This alone can sometimes help resolve addiction issues and put the person in a position to receive treatment for both conditions so that they have a strong chance of remaining clean and sober and mentally healthy in the future.
