Why has my tongue turned white?

well simply we have a case of an overdoce on "THC" . This is not in fact uncommon. You all seem like a very lively and very intelligent group. But from many of my sources and research i have found that my tongue is white because of the " Gange" or marijuana. This in other terms is called Cotton Mouth and has nothing to do with the band THE COTTON MOUTH KINGS. ;)
