Burnt Toast I never said that water would flush the metabolites from the fatty lipids. i merely said drink 8 quarts of water. Here is the info from 420magazine.com FAQ: How to Pass a Drug Test ...

Dilution

Dilution is probably the most common way to ‘cheat’ a drug test. Simply put, you drink a bunch of water and dilute the hell out of your urine. It works like this; say the cutoff for the test is 50 ng/mL, and you’re currently testing at 75 ng/mL (there is no way for you to know exactly where you are, I’m just using these as an example), normally you’d fail. But if you’re pushing twice as much water through your system, suddenly you’re down to 35-40 ng/mL, and you pass. It’s just that easy… or is it?

The exact amount of water you need to drink varies. Don’t go overboard and drink gallon upon gallon of water an hour before your test, as you can develop Water Poisoning if you drink too much. Drinking around 8 glasses the morning before you go in should be enough, but a general rule of thumb is to drink until you’re pissing clear (and running to the bathroom pretty frequently), and maintaining that level by continuing to steadily drinking water right up till you go in the door of the testing facility.

There really is no need to drink enormous amounts of water for the days prior to your test. Since the water you drink that far in advance is already well out of your system by the time you actually go in, it really won’t be much to help you. Just drinking your normal 8 glasses a day should be plenty.

Not Getting Caught

Urine that has been diluted heavily will be visibly paler than normal, which is suspicious, and may be tested for Specific Gravity to check the levels of other common components of human urine and determine if it has been diluted. The easiest way to combat this is to take B vitamins (B2 (Riboflavin) and B12 are considered the best), which will bring the color back to your pee. Try to take between 50 and 100 milligrams the morning before you go in. You can also buy creatine (Red meat is a very good source as well), because some testing facilities do specific gravity tests on all samples, regardless of color. Start eating more red meat or taking your creatine pills a few days in advance of the test, 3-4 days or so, if you have enough notice. If you don't have that much notice, look for a product containing Creatine Monohydrate, which processes through the body faster than naturally acquired creatine.

As I mentioned above, the at-home tests can be useful when you’re diluting, because you can test yourself as you’re getting ready and know when you’re good. It beats the hell out of drinking a gallon of water and still wondering if it was enough....
