There are tons of info on Riboflavin (aka vitamin B2). And it does not cause false positives or negatives. B2 is used during dilution techniques to bring color back to urine.

ALL detox products work because of dilution. That means they work because of the water that youre instructed to drink with them. The ingredients listed do NOTHING to rid the body of THC. The products are nothing but a big scam to seperate the credulous from their cash. You can spend up to $200 on a magic detox potion and accomplish nothing different than what can be accomplished with just water and vitamin B2.

Why feed the scam artists when you can do the same thing by following the guidelines outlined in this link: http://boards.cannabis.com/drug-test...uidelines.html
