Many people in Newcastle, CA. who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who suffer with mental health issues in Newcastle, California also take part in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychiatric condition. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation facility is this sort of issue brought to light. This in itself can help resolve addiction issues and put the person in a position to receive treatment for both conditions so that they have a good chance of remaining clean and sober and psychologically stable in the future.
