Many people in Campbell, 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 struggle with mental health issues in Campbell, CA. also become involved in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate as a way to alleviate the symptoms of an underlying psychological condition. Some treatment clients aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug treatment program is this sort of psychological condition brought to light. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive rehabilitation for both conditions so that they have a good chance of remaining clean and sober and mentally healthy in the future.
