i really need a way to get THC out of my system within a week!!!!!

depends how much you have in your system. Smoked just occasionally? Probably not a big deal. Been a heavy smoker? It'll be hard to clear in a week.

However, bear in mind, THC is lipid-soluble... it distributes into fat, and that's where it's mostly staying when it's in your system. So burning lots of fat, theoretically, could clear it out. I knew someone who smoked lots, was a serious athlete, and could get herself lightly-stoned just from a heavy workout.
SO, that's one option: work out like mad, and burn more fat and the THC might clear faster.
