Many people in Redding, California 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 suffer with mental health issues in Redding, California also take part in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to alleviate the symptoms of an underlying psychological issue. Some treatment clients aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation center is this sort of issue uncovered. This alone can help resolve addiction issues and put the person in a position to get rehabilitation for both conditions so that they have a good chance of remaining abstinent and mentally healthy in the future.
