Many addicted individuals in Nashville who end up in 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 Nashville 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 relieve the symptoms of an underlying psychological disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehab program is this sort of issue uncovered. This in itself can sometimes help resolve addiction issues and put the individual in a position to get rehabilitation for both conditions so that they have a good chance of remaining abstinent and psychologically healthy in the future.
