Surprisingly, as many as 1/3 of those who suffer with mental health issues in Marquette Heights, IL. also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to alcohol or drugs to self medicate as a way to ease the symptoms of an underlying psychiatric issue. Some treatment clients aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab facility is this sort of issue discovered.
