With the significant focus on issues of race and income in urban NC and elsewhere lately, teachers who don't want to submit to drug testing have not gotten much attention. But for reasons that have nothing to do with the common arguments put forth by child/caregiver safety advocates, many more across the country that live off the urban track should be paying very close attention.

Maybe you caught Lisa Ling's (truly) shocking inside investigation into heroin addiction in rural Richland County, OH on a recent Oprah Winfrey episode. http://www.oprah.com/slideshow/oprahshow/20080902_tows_heroin
"Lisa says the most surprising thing about this devastating phenomenon is that it doesn't discriminate.”I could not believe that people of different ages, different socioeconomic backgrounds, were literally dying this slow death in the middle of America," she says. "The reason why it affected me so much is that I interviewed so many people, and every single one of them was begging for help. Nobody liked that they were addicted to heroin."
I have a feeling the teachers in NC don't believe anything that frightening is happening to them, their peers or the children/families they serve. They are most likely correct, for now.
Yet, there is un-ignorable research that the stereotype we have of rural America as a safe haven for our youth is not nearly as accurate as we would like. http://rhr.sph.sc.edu/report/SCRHRC_TeenViolence.pdf
While our teachers may not be drugging it up to the extent we might suspect given their reluctance to be put on the spot, they are working with children who are increasingly at-risk for unhealthy behaviors and therefore they, hopefully, find themselves thinking of ways to set an example and act with integrity in their learning communities.
