from another forum:
when testing UAs they detect a metabolite which is basically what your body produces while a substance is travelling around your bloodstream. the minimum amount to be considered a positive test is when it is 50+ parts per million. diluting your piss means that in the sample there will be more water and less metabolites. if a test however is too diluted ( i.e. all water no other natural waste material that your kidneys filtered out from your bloodstream ) most will count it as a positive, or at the very least make you retake the test.
in order to get around this, instead of just drinking all water, drink about 33% water and 66% gatoraide. don't take any b vitamins... they don't do shit for your urine gravity except make your piss turn a bright neon yellow... when they see that they will know you were trying to get around it. the day before your test eat a light breakfast and an early lunch, and drink a large glass of water. the next day, try not to eat anything, but if you are really hungry just eat a little something at least 3 hours before your test. about four hours before your test drink like three-four gatoraides (16 oz bottles) and one-two glasses (16 oz = one glass) of water.
when you are taking the test, first piss in the toilet for a couple of seconds, fill the cup, then finish pissing in the toilet. most of the waste material is in the very first stream of piss, and the last little bit. if by chance you actually did dilute the piss too much, just tell them that you run/play sports a lot and easily get dehydrated... drinking that much fluid is normal for you.
again, let me reiterate; THERE IS NO PILL/DRINK/CHANT/ADDITIVE THAT WILL MAGICALLY MAKE YOU PASS A DRUG TEST. ANYTHING ELSE BESIDES LIQUIDS LIKE WATER AND GATORAIDE ARE A WASTE OF YOUR MONEY.
hope this helps.

something else i have posted numerous times that belongs here is how long it takes for the traces of pot to be filtered out of your system...
now, everytime you smoke you flood your system with THC... which is then transferred to your brain via the blood stream, then back down to the kidneys where the traces are filtered out... now, your kidneys can only filter out a certain amount at a time, so the more you smoke, the longer it is going to take to get it out of your system.
now, only you know how many times you've smoked in the past couple of weeks, so only you can estimate how much shit is still floating around your system...
the general rule of thumb, is if you are totally clean, and smoke a bowl, then it will take about 24-48 hours for your system to be totally clean again.
now, if you're smoking all day everyday, then it is going to take about 30 days (720 hours) for your system to be totally clean.
now for how clean you need to be in order to pass a drug test, i can only attest to what worked for me...
since i was being tested about once a month, i would smoke for two weeks right after i went in... now this is probably about 3-4 bowls a day...
then for about a week and a half - two weeks before my next test, i would not smoke... then when i go in for my test, i dilute my piss using my method above...
