That goes to show that all "detox" products are nothing but a big scam to capitalize on the so-called "war on drugs" by preying upon the uninformed and credulous, and taking their hard-earned cash.

When the products do work, its because the person had consumed enough water/fluids to facilitate dilution. The dilution factor is what serves as the "mask". The products themselves do nothing to rid the body of THC, as the sales pitches would like the consumer to believe. Anyone who had done any research on how the human body processes THC would understand that there is no product that can permanently rid the body of THC. Only time and fat-burning exercise can do that.

The so-called "money-back guarantees" are not of any insurance that the goop will work. When the individual fails the U/A, and tries to exercise that guarantee, s/he is often told that:

a) "You didnt follow the product directions, therefore the guarantee is void"

b) "Marijuana is illegal and our products are not to be used on lawfully-administered drug tests; therefore the guarantee is void"

For your next U/A, forget the snake-oil products and follow the steps outlined in the Dilution "sticky" thread (skip the aspirin step though) if you choose not to use a clean persons sample as a substitute.
