Drinking lots of water will not get THC out of your system any faster. It will still take 3-5 weeks to clear for a urine test, up to 6 months for a hair test. Drinking lots of water on the day of your test will dilute your sample though. However if your sample appears too clear this may lead them to invalidate it. To avoid this take some B complex vitamins an hour prior which will yellow up your sample.

Edit: With respect to the next post, it is impossible that THC would leave the system in 3-5 days, no matter the frequency of use. In fact, less frequent use can cause it to stay in your system even longer as your body is not used to processing it. Bottom line: you're looking at 3-5 weeks for a urine test. LOTS of water... But don't over do it...

LOTS of cranberry juice.... It cleans out your kidneys.... don't touch the stuff in the first place. water and plenty of it Don't smoke weed. don't smoke weed and, don't depend on anything except not smoking for negative results. good luck There is nothing " free" per-say... dont smoke...

But I have heard of people taking Niacin ( no flush) from the GNC stores.. or the detox drink that costs 30-50... works... just drink it 4 hours before... and yes with that also is alot of water... but its worth the money if you NEED to pass the test.

The length of time that the presence of drugs of abuse in the body can be detected is an important factor in drug screening. The chart below outlines approximate duration times. When interpreting the duration for the presence of drugs of abuse in the body, you must take into consideration variables including the body's metabolism, the subject鈥檚 physical condition, overall body fluid balance, state of hydration and frequency of usage.
