Many individuals in Chapman 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 struggle with mental health issues in Chapman also take part 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 ease the symptoms of an underlying psychiatric disorder. Some addicts aren't even diagnosed with a disorder, and only when they make it to a drug treatment facility is this sort of issue uncovered. This in itself can 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 clean and sober and psychologically healthy in the future.
