How do you pass a drug test?

I had a drug test today and I was dirty but I drank like a 48oz bottle of water that contained a full scoop of "creatine blast" powder along with a water bottle and I also took like 6 vitamin b one daily vitamins to pass but my only concern is that the creatine didnt get into my system fast enough to work i drank 25% of it throughout the day and the other 75% about an hour before the test...Basically my question is would I show up diluted?
