yeah you can sniff hydro but its nasal BA is crap. i know every one wants a faster rush so im sorry i cant tell you itll knock you off your feet but....it wont. any 'codone' is weaker than any 'morphone' because the codones have a methoxy group...which makes it less water soluble and forms less hydrogen bonds. and any 'hydros' are weaker than 'oxys' because oxys have a hydroxy group which IS more water soluble and forms stronger hydrogen bonds. so...hydrocodone is pretty much the weakest nasal opiate other than codeine. just eat them. BA is like 80% oral and feels just as good. also...your body converts hydrocodone into hydromorphone through metabolism so if you have no APAP and you take a significant amount...youll get a better buzz off eating them cuz those metabolic enzymes are in your blood and digestive system. nomnom
