Many individuals in Vernon Hills, IL. 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 Hills, Illinois also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to relieve the symptoms of an underlying psychological condition. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehab program is this sort of issue brought to light.
