Dunlap the myth behind this gelatine eating crap is that when you eat the pack full of jello (this is what most people do since the active "gellin" ingrediant is hard to find seperately) it coats your stomach. Meaning when you drink water before your test it will not be able to go through your system and pick up the THC metabolites that are stored there. Frankly, this is only a myth it does not work at all. Ive heard stories of people passing using this method but the logic behind it is none. I dont reccomend anyone doing this for you dont know what eating a whole pack of jello will do to you......any volunteers
