It tastes like shit. I tried and tried and rolled fatter and fatter joints and I couldn't stand the taste. If it had an effect I could have lived through the taste, but it did NOTHING. I threw mine away. I have heard a couple people say it was good, but my guess is they sell the shit. I will tell you that it will get easier to go without, but what about the stuff that makes your test come out clean? I don't know much about it, but I have heard a lot of people say it works and I think there are several different things you can use. And if I may ask, why will you be tested weekly?
