Many individuals in Princeville, Illinois who end up in 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 Princeville, Illinois also become involved in substance abuse at some time in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate in an attempt to alleviate the symptoms of an underlying psychological condition. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they make it to a drug treatment center is this sort of issue discovered.
