    Urine tests are a common method of drug testing. They're simple and relatively cheap, with most labs offering them for free (at least if you're not a total novice). A urine test takes the form of a test strip that is dipped into your pee stream to give an instant result—within seconds! If you've ever wondered whether or not it's possible to cheat this kind of test by drinking water before taking it, keep reading.

    What is a urine test?

    A urine test is a common form of drug test that's used to detect the presence of drugs in the body.

    Urine tests are done by taking a sample of your urine and testing it for traces of any substances you may have been using. It's important to know what can be detected by these tests so you can prepare beforehand if necessary!

    Can you eat or drink water before your urine test?

    The short answer is yes, you can eat and drink water before your urine test. The long answer is that you should not do so.

    If you are given the option of consuming food or beverages before taking a urine test, we recommend that you refrain from doing so. This is because it may cause the sample to be diluted and therefore invalidate your results. You will still have to submit another sample if this happens--and in some cases (such as when drug testing), failing to produce an adequate specimen could lead to serious consequences like losing your job or being arrested!

    If there's no time for lunch before arriving at the clinic/hospital/lab where they'll collect your sample? Don't worry: just make sure not to eat anything else over 24 hours prior to submitting for testing purposes (even if it means skipping breakfast).

    How long do drugs stay in your urine?

    The length of time a drug will stay in your urine depends on the substance and how much you take. Some drugs, like marijuana, can be detected for up to 5 days after use. Other substances like alcohol can only be detected for about 24 hours after use.

    Some drugs may also leave traces of themselves in your system even after they've been cleared out by your body; these are called metabolites. Metabolites are produced by the body as it breaks down the original substance (for example: when alcohol is converted into acetaldehyde).

    Can you get clean urine for a drug test?

    You can get clean urine for a drug test by using synthetic urine, fake penises and other devices, or by substituting someone else's sample.

    However, you should always consult with your doctor before attempting any of these methods.

    The best way to pass a drug test is to try not to get in that situation in the first place.

    The best way to pass a drug test is to not have to take one.

    If you do, here are some tips:

    • Avoid drugs and alcohol in general. If you must drink, know your limits, as well as those of others around you. And if someone else offers you something illegal--say no! It's not worth losing your job over something that could be solved with some water and time spent away from work for observation purposes (AKA "the hospital").
    • If there's no way around it and testing happens on site at work or school (or wherever), make sure that before taking the test they ask how long ago was the last time I smoked/drank alcohol? Because I had two beers yesterday night but haven't touched anything since then." This will help them understand why there might be traces left behind after only 24 hours since consumption occurred; plus this kind of question makes them think twice about whether or not you're trying anything funny during their investigation process so it also works in our favor by making sure nothing else sneaks through unnoticed!
