"cheese" is just the new "chiva" which killed a lot of high school kids in Plano,Texas who did not know supposedly that it was black tar heroin that was frozen,then put in a blender with Benedryl powder to make the tar into a snortable form.How they can claim not to know it was heroin is beyond me,but "cheese" is apparently the same as the "chiva" was basicly.Also Chiva is slang in mexican spanish for heroin altho it translates to goat.Also as far as putting tar up your nose,that has been popular along the Texas/Mexico border for years to dissolve tar in water and squirt it up the nose using a nasal sparay medicine bottle for the spray.I suppose it must get you high depending on how much you do,they call it shebanging also.
