If you slam water how long does it take to pass a drug test?

Answer 1

Slamming water doesn't always have the desired effect in urine drug screens. Most places that have regular, random drug screening also have concrete policies in place regarding what is considered a dirty. To keep individuals from "cheating" thermometers are often used, to make sure the specimen is fresh, and creatinin levels are tested with the drug levels, to make sure it is not diluted. A normal person will have creatinin clearing their bodies at all times, and within a known range. If that level is excessively low, then the lab knows that the urine has been diluted either after the specimen is in the cup (eg:with water from the faucet), or before (by drinking too much water rapidly). There are other ways that diluting urine specimens can be caught.

IF there is no safeguard against diluting the samples, then it is safe to assume the following, keeping in mind that there are a host of other things that effect the time that it takes a drug's metabolites to clear the urine: Opiates (heroin, morphine, oxy), cocaine/crack, and methamphetamine can take between 3 days-and-up to a week to clear under normal circumstances, with frequent water and urination you may be able to cut that in half. Marijuana, Hash, and benzodiazapines (valum, xanax, klonopin) are fat-soluable and can take from a week to a month (usually more) to clear from the urine. Water dilution may be able to reduce that slightly, but don't count on it.

One final thing to consider is that if the urine is processed in a lab using a GMS, and not with just a "dip test" then the urine will be spun down in a centrifuge and only the "good parts" will be used, making dilution with water useless.
