Knotme66 thanks for your response you are right but i have done some homework on this subject maybe i did not ask the right questions and yes you are right i should have thanked crookedc for responding to my post instead i came off sounding like a smartass and thats not what i am here to do.My point is that i would like to hear from someone that has tried certo or something simular and would like to hear there results i have been smoke free for 1 week today i followed iamn2pot dilution tips to a tee today took a home test and failed! i am active, skinny and in pretty good shape! the problem is that i do not know how to moderate and smoke like crazy! i am not looking for the magic wand & i know everyone is different but i would like to hear from somebody that has tried a alternative to dullution did they fail did they pass? at this point i do not have any confidence that i can pass a test which is tomorrow by dilution & do not have a lot of time to do extensive research so if anyone has been in my situation please share your experience thats it thanks!!!!!!!
