Many addicted individuals in Mark 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 struggle with mental health issues in Mark, Illinois also become involved in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychiatric condition. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment facility is this sort of psychological condition uncovered. This in itself can help resolve addiction issues and put the individual in a position to get treatment for both conditions so that they have a good chance of remaining clean and sober and psychologically stable in the future.
