Many people in Oakland who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who struggle with mental health issues in Oakland, CA. 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 psychiatric condition. Some treatment clients aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug treatment center is this sort of issue uncovered. This alone can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both conditions so that they have a good chance of remaining clean and sober and psychologically healthy in the future.
