Many people in Vernon, 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 suffer with mental health issues in Vernon also take part in substance abuse at some point 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 disorder. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they make it to a drug treatment program is this sort of issue uncovered. This in itself can help resolve addiction issues and put the individual in a position to receive treatment for both disorders so that they have a strong chance of remaining abstinent and psychologically stable in the future.
