Many people in Shandon, California who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Surprisingly, as many as 1/3 of those who suffer with mental health issues in Shandon, California also take part in substance abuse at some point in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to relieve the symptoms of an underlying psychiatric disorder. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment facility 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 disorders so that they have a strong chance of remaining abstinent and mentally healthy in the future.
