This is the only method of fooling a drug test that has been proven to be effective. By diluting the urine you reduce the concentration of THC metabolites to passable levels¹. Now when I say dilute your urine I don’t mean to add a little toilet water to the sample. That’s called spiking and it’s dangerous for many reasons. The first reason is that most places tint the toilet water blue and keep you away from any sinks; so you can’t use any water at the facility. If you manage to sneak some water in with you and add it to your sample it will most likely be flagged for at least one of three reasons: The sample will be too clear, the specific gravity will be too low, or the temperature will be too low. This method is extremely ineffective and only recommended for the most dire of situations.
To dilute your urine you have to drink as much gatorade as possible on the day of the test. It’s a very basic principle. The more you drink the more you will pass thus lowering the concentration of the THC metabolites. You’re going to have to drink as much as you can physically hold, starting about 3 hours before the test. If you’re doing it right you should be urinating about every 20 minutes. It’s important that you use gatorade and not water because the electrolytes and sugar in the Gatorade help keep the specific gravity of your urine at a normal level. If the specific gravity is too low the test will be deemed inconclusive and you will have to take it again. Also remember that it doesn’t matter how much you drink on days prior to the test. Your body passes the THC according to the speed of your metabolism regardless of how much you drink². All that matters is that you drink as much gatorade as possible on the day of the test.
This causes two problems however. The first problem is that diluted urine is clear in color when normally urine is yellow. Any urine that is too clear will be flagged as being tampered with. To avoid this all you have to do is take some multivitamins on the day of the test. Multivitamins contain large amounts of B vitamins which are water soluble and pass through your urine. The presence of vitamins gives your urine a bright yellowish, almost neon, color. You will need to experiment with the timing of your multivitamin consumption to see how long it takes to give your urine color. Your best bet is to take multiple multivitamins at regular intervals throughout the day of your test.
The second problem is that diluted urine has low levels of creatinine.
