Many people in Marquand 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 Marquand, Missouri 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 in an attempt to alleviate the symptoms of an underlying psychiatric issue. Some addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug rehab program is this sort of issue uncovered. This alone 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 abstinent and psychologically stable in the future.
