had a buddy that smoked the night before his test, went to Walgreens and picked up medicine for a urinary tract infection, drank a crap ton of water and held his pee as long as he could that night (piss looked all bright orangey when he went). considering he passed this test for the marines i was pretty impressed.
i would say if you have more than a week or two you should be in the clear as long as you drink an insane amount of water, cranberry juice, tea, and stuff mixed with vinegar. i would also recommend running/lifting/working out as much as possible because you can also sweat a lot of it out. good luck bro.
I want to pass one. How do I do it?
(And don't anyone say 'don't take drugs' cuz its too late for that sh1t)
Get a real job where they don't require drug tests.
this as well.
