How to Pass a Urine Drug Test – The Basic Methods Explained

in Urine Drug Tests

How to pass a urine drug test is addressed here. (Follow this link for information on how to pass a saliva drug test.) There are several different ways you can pass a urine test, and I’ll give you the pros and cons of each. I should tell you up front that I’m a big advocate of dilution, but that doesn’t mean I can’t be objective about the other ways too. Depending on your situation, it’s possible that a different method would actually be better for you. I’ll just lay out how to pass a urine drug test using each one, and you can decide for yourself.

First of all, how to pass a drug test can be broken down into four basic methods:

1) Detox products
2) Dilution
3) Synthetic urine or substitution
4) Natural detox

How to Pass a Urine Drug Test Using Detox Products

There are so many different detox products on the market for passing a drug test that it boggles the mind. But they can basically be broken down into two categories: detox kits and detox drinks.

A detox kit is how to pass a urine drug test only if you have some time before your test. Most companies selling these products advertise anywhere from 10 days to 30 days for the product to work. But if you’re a pretty light smoker and you have 30 days notice, then you’ll definitely be clean by the time you take your test anyway, so you should just save your money. On the other hand, if you’re a heavy smoker and you only have 10 days to plan, then a detox kit definitely won’t work for you in time.

On the other hand, if you have very little advance notice, then a detox drink can be a good method for how to pass a urine drug test in a hurry. The people who have the most success in passing a drug test with them are light to moderate smokers. Detox drinks are really just a convenient way to use the dilution method (see below). The drink itself contains ingredients to help mask the fact that you’re diluting, and the instructions that come with them tell you to drink lots of water along with the product. However, they’re not among the best ways to pass a drug test if you’re a heavy smoker, or if you happen to be overweight. For one thing, the amount of water that they recommend you drink is usually much too low for those situations. Also, some of them tell you that you’re safe for passing a drug test for up to 5 hours after you drink the product. You should NEVER take a detox drink that far ahead of your test – 1 to 2 hours before your test time is safest.

How to Pass a Urine Drug Test Using The Dilution Method

As I’ve already pointed out above, I’m partial to dilution when it comes to how to pass a drug test. Mainly because it can be adjusted to work for anyone, whether you’re a light smoker or a heavy smoker. If you’re a light to moderate smoker you might prefer the convenience of just going to a store and buying a detox drink. But for heavy smokers, your safest bet is to do it the old-fashioned way so that you can control the process.

Dilution is a very effective and affordable method for passing a drug test. The way it works is pretty simple – you just need to drink enough fluids so that your kidneys are overloaded to the point that your urine is completely diluted. When that happens, then there aren’t enough THC metabolites (or much of anything else one usually finds in urine, for that matter) present in your urine for it to register on a test.

Contrary to the misinformation that gets passed around, there is NO need to load up on extra water before the day of your test. Drinking lots of water everyday is good for your general health, but as far as how to pass a urine drug test goes, it’s a complete waste of time and effort. What IS effective is drinking enough water in a short time span (2-3 hours) so that your urine is as dilute as possible.

But diluted urine is very clear, and not the normal yellow color it’s supposed to be. Of course this is a red flag to drug testing labs, so you’ve got to take a few steps to make it appear normal. Taking between 50-100mg of a B-complex vitamin (specifically B-2) about an hour before your test will make your urine appear yellow again. You also want to make sure that your urine contains normal levels of a substance called creatinine (you can buy a supplement called ‘creatine monohydrate’ in just about any health store that will accomplish this). Most labs also test the density of your urine specimen. You can get detailed, step-by-step instructions on how to dilute properly in my e-book about passing a drug test.

And if you really want to make sure you know how to pass a urine drug test using the dilution method, I highly recommend buying drug test strips and doing a trial run before your real test. You can get the strips in major pharmacies (Wal-Mart is probably cheapest, if there’s one in your area) and sometimes in smoke shops, but they tend to be expensive there. If your recreational drug use is limited to just pot, then you’ll save money by getting single-panel strips instead of the 5-panel strips. If you have time to plan, the cheapest place I’ve found them on the Internet is on this website.

How to Pass a Urine Drug Test Using Substitution or Synthetic Urine

Substitution was one of the earliest ways to pass a drug test used by pot smokers. All you have to do is ask a friend for some of their (clean) pee, and then smuggle it into the lab. Sounds simple in theory, but it can be very risky since lab technicians will monitor you to try and prevent you doing this.

Just smuggling your sample into the lab is only part of passing a drug test this way. You also need to somehow keep it at body temperature, since that’s one of the first tests a lab will do. Cold pee = failed test, game over. But you can keep the sample at body temperature by securing it in a zip-loc bag to the inside of your upper thigh, or you can buy devices on the Internet that are specifically designed for this. Since a lab technician is usually close by to monitor you, you also want to make certain that the container you use doesn’t make any noise when you open it (no rubber bands or tape, etc.).

Using synthetic urine works the same as substitution, except that instead of using a friend’s pee, you’ll be smuggling in the synthetic pee. It can come in powder form (which you’ll have to mix with water) or in liquid (pre-mixed) form. Labs have tests they run to try to detect synthetic urine, but the companies who make it are constantly working at staying one step ahead of them. If you’re successful at the smuggling part, then the odds are high that the synthetic urine will pass.

Depending on the circumstances at the lab you’re going to, both substitution and using synthetic urine are among the riskiest ways to pass a drug test for most people. If you’re caught, any false positive arguments go out the window and you won’t get a chance for a re-take. So knowing how to pass a urine drug test this way definitely requires that you have some advance knowledge about how closely you’ll be monitored by a lab technician.

How to Pass a Urine Drug Test by Naturally Detoxing

If you know you’re going to be needing to take a drug test in the future, for example if you’re going to be looking for a new job, of course you can always just stop smoking altogether and wait until THC metabolites have left your body through natural means. A serious workout regimen to lose weight will hurry the process a little bit, since THC metabolites are stored in your fat cells. But this method is only how to pass a urine drug test if you’ve got plenty of time, really (and assuming you can handle being separated from mary jane for an extended period). Both of those complications makes this one of the hardest ways to pass a drug test for most folks.

If you’re an average weight person who is a very light pot smoker (maybe a bowl once a month), then you’ll be clean in just a matter of days, like less than a week. If you’re a once daily moderate smoker, give yourself 3-4 weeks to get clean, depending on your metabolism. And if you’re a heavy smoker (several times daily), or if you’re carrying some extra weight on your, then passing a drug test by naturally detoxing will generally be between 4-6 weeks. These are just ballpark figures though, because your individual metabolism has a huge influence here. But in general, the faster your metabolism is and the less body fat you have, the faster you’ll get clean.

Final Word of Advice on How to Pass a Urine Drug Test

Regardless of what method you choose to use, how to pass a drug test consists of knowing exactly what you’re going to do when you walk into the lab. This is one situation when the saying “knowledge is power” is especially true. People pass drug tests EVERY DAY, and there’s no reason why you can’t too if you take the time to do your homework beforehand. And one big benefit of being prepared is that it removes a huge amount of stress from the entire issue of how to pass a urine drug test.

ok heres the facts for me:
I smoked for the first time in my life two days ago and i have a drug test coming up as early as monday for a job. So that leaves me bout 6 days. It was the first time I have EVER smoked before in my life. Pretty much the first time ive ever been around it anyways. Im 17 years old, 6 feet tall, 170 pounds, little to no fat, pretty good metabolism, light eater, workout (lift weights) frequently. What are my chances of passing without diluting before the test and having clear pee?

p.s. it was a couple hits off a bong. a good bong tho

You’ll pass with no problem, no need to worry, man. You’d probably pass a test if you took it today, so if you have six days don’t sweat it.

I am a daily smoker and I will be taking a drug test late next week 3\209 or so. I have been drinking plenty of water and will continue to do so. Do you think that I will dilute within a week so that I dont have to dilute during the test?

It doesn’t work that way, Marc. You need to read this article more carefully. Only the water you drink on the day of your test will help you pass.

Reply

Dee March 12, 2009

geen, if you smoked a bowl and you also didn’t smoke anything for a month or more before that, then you’ll probably pass just fine. On the other hand, if you smoked regularly up until 5 days ago, then it’s definitely not long enough to pass and you’d better dilute.

If you’ll be in a situation where people will be able to observe your actions pretty closely for the entire 4 hours, then to be honest, dilution probably won’t work for you. You might want to start thinking of ways you could smuggle in some clean pee (NOT synthetic though, too many labs are finding ways of detecting that).

Dee February 20, 2009

If your B-complex makes your pee turn neon yellow under normal circumstances, then it will most likely help you, yeah. The B-12 by itself won’t do anything though. Hope this helps.

Drug test in 2 days and in the last week I’ve taken about 4 of my husband’s lortabs (one a day, or every other day, with the last one 2 days ago). Should it be out of my system within the next few days?

Also, I’m taking 1 Xanax at night to sleep – do I bring the bottle with me to to the lab so I can prove that its prescribed?

Thank you!

Se você conhece o meu Inglês ebook tem informações que podem ajudá-lo, mas por outro lado queria apenas recomendar que você beba cerca de 3 / 4 de um galão de água de cerca de 3 horas antes de começar o seu teste. Também ter alguns vitamina C para se certificar de que sua urina é amarela, não estava claro. Sinto muito, eu desejo que eu poderia ajudá-lo mais .
