The metabolite THC, found in marijuana is what a urine drug test will be detecting. THC can stay in your system anywhere from 1 week to 1 month. THC stores itself in fat cells. The rate that THC passes through your system completely depends on several factors: Your body fat percentage, how much you smoke, how often you smoke. For example, I smoke marijuana every time I go out partying. I party every other week-end. I am a chemist and run drug screens on my analyzer at work. I tested myself after 1 week and I was negative. Another time, I had not smoked in probably a month. A friend and I smoked 2 big joints one night. I made a bet with her that the next day I would go to work , test my urine, and that it would be negative. I won the bet!
Drinking large amounts of water does dilute your urine. However, if you are taking a DOT drug screen, where they seal and you sign....if the lab they send it to believes you have diluted the urine (tell by color) they will test it (in simple terms) for certain analytes that should be present in a non-diluted sample. I recommend.....drinking as much water as you can. Go to a store and by some vitamins, take them and still make sure you drink plenty of water. The day of testing, while still chugging that water, drink a large gatorade about twenty minutes before the test. After you drink the gatorade......try not to urinate until the test. The electrolytes from the gatorade will be in that last sample and if the reference lab test for metabolites in your urine.....there's the gatorade!!!!
