If thats truly the case, then you would fail if you drank a gallon of certo/water cocktail, considering that certo "works" because of the dilution factor. There is no product that can rid the body of THC. Drug tests look at drug metabolites - not residues, especially the type of residues found in bowls and bongs. Two different pair of shoes dude. As I stated earlier, only time and exercise can permanently rid the body of THC.
