Many people in Derrick City 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 Derrick City also become involved in substance abuse at some point in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate in an attempt to alleviate the symptoms of an underlying psychiatric disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they make it to a drug rehab facility is this sort of issue uncovered. 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 good chance of remaining clean and sober and psychologically healthy in the future.
