Sure I have. It's here. In town.
It's outside of town, too. Your formulation that drug abuse is a product of the urban "party scene" is largely true of crack, ecstasy, and maybe even heroin, but pot is pretty much universal, and meth is actually more prevalent in rural areas than in cities.
See http://www.usdoj.gov/dea/concern/map_lab_seizures.html for a map of meth lab incidents in 2008. New York state had nine; Missouri, 1,471.
This site, citing a study from the University of Nebraska, suggests that rural meth users start younger, are more likely to shoot up and drink heavily in conjunction with meth, and are more likely to exhibit meth-induced psychosis.
Your mental picture of "rednecks" having a little rowdy fun with booze and a little weed is out of date.
