buy xanax Q&A

okay. please no lectures. i just need help.
the last time i smoked weed was like a week ago.
i am small, i wiegh about 95 pounds, but i don’t eat very healthy, and not much into exersize. just incase you needed to know that info.
but anyways, i got in trouble for something stupid, and i now have a hearing that i may or may not be drug tested at.
i need to know the fastest way to get my pee to pass with out using someone elses pee and without buying any detox pills other then things that i could easily buy over the counter.
please help, i know i made a mistake, and i plan on quiting smoking weed, but i desperatly need to pass this test.
and btw, i took two xanax for the first time like four nights ago, it didnt do much to me, and i did this before i realize i was going to get drugg tested, but does something like this show up in a pee test?

my friends hot boxed a car 2 weeks ago and the next day i bought this 7 day detox program. and yesterday someone put a xanax bar in my drink will i be able to pass my test in less then a week

I only have Xanax and Hydrocodone in my system. Will this product I bought from GNC work, and if so, how do I use it properly?
