Many people in Lemont Furnace who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who struggle with mental health issues in Lemont Furnace 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 psychiatric issue. Some treatment clients aren't even diagnosed with a disorder, and only when they make it to a drug rehab program is this sort of issue brought to light. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive rehabilitation for both conditions so that they have a strong chance of remaining clean and sober and psychologically stable in the future.
