Many individuals in Scarville who find their way to 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 Scarville, Iowa also become involved in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate in an attempt to relieve the symptoms of an underlying psychological issue. Some treatment clients aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab program is this sort of issue brought to light. This alone can help resolve addiction issues and put the individual in a position to get rehabilitation for both disorders so that they have a good chance of remaining abstinent and mentally healthy in the future.
