How To Pass a Drug Test Fast for Weed


Learning how to pass a drug test is essential if you have to get clean for your job. Urine drug tests are the most commonly used way employers test for marijuana.Urine drug tests are popular because they’re cheap, easy to use, and are the only testing method approved for federally-mandated testing.

If you’ve been enjoying yourself over a long weekend and need to clean up quick, we have you covered, This post will go into all the different ways of how to pass a drug test.

Metabolites are the byproducts of substances processed by your body. When a drug test is testing you for marijuana use, it is not looking for THC in your system. It is instead looking for the THC metabolite that your body produced.

For at home urine tests you simply have to put a test strip in a sample of urine and wait for a predetermined amount of time before comparing the results to the key. These generally show two lines. One of the lines is for the control, a test to determine if the sample is in fact urine. The other line will be the testing line, which will show if the metabolite of the drug you are testing is present.

Sometimes an employer will send your urine sample to a lab to get it screened instead of using an at home drug test. These labs will measure pH, creatinine, specific gravity, and will test for adulterants that people add to tamper with the drug test.

How Long Does Marijuana Stay in Your Urine?

Urine drug tests can detect marijuana for up to 6 weeks after you smoke. But on average, people stop testing positive after a week. Keep this in mind when it comes to how to pass a drug test.

However, by following the steps below, I’ve seen heavy smokers pass a drug test after only 2 days.

How to Pass a Drug Test

There are two keys to passing a urine drug test.

1. Flush out as many metabolites as you can in the week(s) before the test.
2. Dilute your pee as much as possible on the days before the test.

You don’t want to be flushing the marijuana out of your system and into the specimen cup.

Drink Water

Start drinking water now. As much as you can and at least a gallon a day. You never want to put down that water jug. Water is the #1 key in passing a drug test. Without water, your body has nowhere to expel the marijuana in your system and your urine won’t be diluted when it comes to testing day.

Sweat It Out

Start exercising Now but stop 48 hours before your drug test. THC is fat soluble and is stored in your fat cells. Exercise will burn fat cells releasing the THC in the fat tissue into your system to be processed out of the body. You want to help get as much out through physical activity as possible, but then allow at least 48 hours rest to flush out the THC that you released.

Boost Your Body’s Metabolism

Eat lots of vegetables, fiber-rich foods, and foods high in protein. Avoid sugar, high-fat foods, and other junk food so that your body works on burning off the fat it already has instead of storing new fat.

Leading up to your test, also avoid red meat as it may raise creatinine levels in your urine, one of the chemicals tested for.

Increase Your Urine Output

Take a diuretic such as Midol or cranberry juice.

Cranberry juice and Midol help you urinate more often.  This will dilute and flush out the metabolites in your urine.

Take Aspirin

Four to Six hours before your test take 4 aspirin. Studies show that aspirin interferes with Enzyme multiplied immunoassay technique(EMIT) drug screening, is a common method for masking certain parts of the spectrum that urine tests check.

Take a B-complex Multivitamin

Two hours before your test take 100 milligrams of a B-complex multivitamin. After drinking gallons of water and taking a diuretic, your urine will probably be pretty watered down and should be crystal clear. This clear pee can raise suspicions. Taking B2 or B12 can help to bring it back to that familiar yellow glow.

Take Certo

Two to three hours before the test take a box of Certo, mix it with water and drink it. Certo is fruit pectin which is a fruit fiber. Fruit fiber is extremely water soluble and binds with your fatty acids where THC is stored.

However, Certo only works temporarily because your body is always breaking down fatty acids in your body.

Additional Tips How to Pass a Drug Test

  1. On the day of the test, pee at least twice before you go.
  2. When you pee in the cup, catch the middle of the stream for the cleanest pee.
  3. Test your pee before you take your test so you know you’ll pass.
  4. Avoid sodium and other dehydrating substances.

Using Fake Urine

Fake urine is highly reliable, and unless your drug test is for the Department of Transportation or Department of Corrections, it cannot legally be observed unless tampering is suspected for the first sample. This means that as long as you can smuggle the small container of fake urine into and out of the room with you passing a test is no problem.

Synthetic urine kits are made of the exact same liquid used to calibrate the lab testing equipment your test is analyzed with. So don’t worry about the sample being found out by the fancy gas chromatography–mass spectrometry machine. It simply doesn’t know the difference.

Buying Fake Pee

Most people know how to pass a drug test coming up and have time go to the local headshop. Headshops will have a selection of all sorts of cleansing drinks, as well as a selection of the finest in fake pee. Ask for the guy’s recommendation, brands vary regionally but I like Quick Fix.

Using Fake Pee

The day of the drug test I toss an outfit in the dryer, and once done pull it, and grab my fake piss and go to the bathroom. I take out the handwarmer that the kit comes with and strap it to one side of the bottle to start warming it up just remove from plastic to activate the hand warmer.  I wrap the bottle and handwarmer up in my now warm outfit and hop in the shower. By the time I’m done, the bottle has warmed up to temp and is ready to go.

I hide it in my underwear, heat pad facing out and with good skin contact so that the sample status at the right temp. Head to the testing location, sign a form, wait 5 minutes, then get escorted to the bathroom next up, I empty my pockets into the locker they provide.  I go in, and close the door. Now the fun part, you have a worker standing outside of the door, possibly listening, although probably checking Facebook.  I like to grab out everything I need from my underwear, start peeing, pinch midstream, fill up specimen cup with fake piss. NONE OF YOUR OWN!

Hide the fake pee bottle, open the door, hand off your sample cup to the tech. This is the critical moment as long as everything is in the right range, the little temperature strip on the side of the cup should show between 94-99 degrees. When the tech sees that it makes temp, they accept the sample and your job is done.

    • Midol is a diuretic and will make you go pee more often. Peeing more often will help with both flushing out the THC and diluting it. If you don’t have access to Midol or another diuretic I would suggest drinking as much water as you humanly can, which will have the same effect.

  1. Also, the article mentions that if ur urine is too clear, it might raise suspicion. Well, I have a few things to say about that. If you drink the amount of water in a day that you are “suppose” to drink, of course your pee is going to be clear. Also, I have been in a situation where my sample was “diluted”. Some places count that as an automatic fail. However, some places let u take it again, buying you time to flush more.

    • We aren’t saying that if your urine is clear it won’t work. We’re simply saying that if you want to have zero problems in there, it’s suggested to not overload yourself with water since it will seem like you’re trying to dilute it. People drink that much water but it does raise suspicion since you know about the test in advance.

  2. What about using something called Certo. I’ve heard that those are really good for passing. Like even for those who smoke everyday. I’ve not tried it, I’ve only seen yt vidoes for it. And one video showing it fooled a drug test bought from dollar tree. But could it fool a lab test? Or a drug test used at say a grocery store.

    • Certo doesn’t work. If you passed with the certo method it was because your piss was diluted from the excess liquids you consumed with the certo.

    • That only worked on the original emit drug test that were used mostly before 2005. The new emit test aspirin won’t help at all.

  3. Really guys on

    Dude ya all are saying 4 to 6 hours lol my boyfriend took 3 aspirin in the morning day before in morning 3 at night and the morning before test took 3 more drink a total of 5 bottles of water and his thc levels went from 1900 to 100 you all are crazy you can’t do it right before the test and think u passing lol this method passes you in 3 days
