Many people in Vermilion, IL. who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who suffer with mental health issues in Vermilion, Illinois also become involved in substance abuse at some time in their lives. These dual diagnosis clients frequently 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 treatment program is this sort of psychological condition uncovered. This in itself can sometimes help resolve addiction issues and put the person in a position to receive treatment for both disorders so that they have a good chance of remaining abstinent and mentally healthy in the future.
