dude jus drink ALOT of water and cranberry juice.....that always does the trick.( when i did it i always had like 2 days ahead of me) and also if you get one of those detox i suggest you take it today cause some you have to wait 6 to 24 hours for it get out of your system or you wiil fail tha test.

believe me i would know. i used to smoke all tha time.
