How To Pass A Urine Drug Test

Marijuana drug tests are cheap and sensitive. But how long does weed stays in your urine? And how do you flush it out of your body? We explain how and why.

One of the most common questions people have about cannabis is how long does weed stay in your system? This is a pressing question because there are a lot of employers who require some sort of drug testing. And a failed test could seriously damage your prospects of getting or keeping a job. One of the most common ways employers test for cannabis use is to analyze urine. These tests are fairly cheap and are extremely sensitive to traces of cannabis. So, how long does marijuana stay in your system? How long does weed stay in your urine? This article will explain to you everything you need to know.

THC vs. THC-COOH: The Science Behind Urine Drug Tests

The first thing you need to know is what exactly a urine test is looking for. Surprisingly, they don’t actually detect straight THC. What these tests are really trying to pick up is a chemical called THC-COOH.

When you consume cannabis, THC enters your bloodstream and gets you high. After your body processes the THC it creates a new derivative chemical. And that’s what THC-COOH is.

Urine tests have been designed to detect the presence of THC-COOH since the only way that chemical would be in your body is if you’d already used cannabis.

The problem for pot smokers is that THC-COOH stays in your system much longer than THC. That means that you can test positive for cannabis even if you haven’t smoked for days.

Time Test – How Long Does Weed Stay In My Urine?

How Long Does Weed Stay In Your Urine?

OK, now that we’ve got a little science beneath our belts, let’s get back to the big question. How long does weed stay in your urine?

There are a few key factors that determine the answer to that question. How frequently you use marijuana, the size of your dose, and the way your body metabolizes THC all impact how long it’ll stay in your urine.

Since there are so many variables, it can be hard to pinpoint a precise amount of time that THC-COOH will stay in your urine. But researchers have come up with some general timelines that will help you gauge how long your urine will turn up positive for cannabis.

Here’s What the Research Shows

  • One key study found that weed can stay in a person’s urine for a surprisingly long period of time. That study found that urine will test positive for THC an average of 27 days after use. Heavy users can test positive for as long as 77 days after a smoke sesh.
  • 1-time use will usually stay in your system for 5-8 days.
  • If you use cannabis 2-4 times per week and then stop, you’ll test positive for 11-18 days.
  • If you smoke 5-6 times per week, it’ll stay in your urine for 33-48 days.
  • And if you’re a serious smoker who gets high every day, weed will stay in your urine for 49-63 days.

The Problem With Urine Drug Tests

The obvious problem for anybody who uses cannabis is that you can test positive for a long time after your high has worn off. Think about it, even if you smoke once and then stop you can get a positive urine test a full week after you actually puffed.

Critics of drug testing have long pointed out the problem with using urine tests as a way of determining who uses drugs. These critics have pointed out that an employee who lives in a state where pot is legal can follow all the rules and still get in trouble at work when their urine test comes back positive long after they’ve actually sobered up.

How Do I Pass A Urine Drug Test?

Given all this, many people want to know how to pass a drug test. The most effective plan is to use the timelines above to schedule your cannabis use around your next urine test.

That’s easier said than done since a lot of drug tests are random. You probably won’t know when you’ll be asked to turn in a sample. But if you do have an idea of when you’ll have to do a urine test, be sure you know how long it’ll stay in your system and plan ahead.

Besides that, you can try drinking a lot of water and other fluids (a lot of people swear by cranberry juice) to try and dilute your urine. Be careful, though, because a sample that’s too watered down might come back as invalid.

If you’re willing to take a super risky approach you can try smuggling in a clean urine sample. This is obviously incredibly dangerous, as it’s blatantly cheating the system. And if you get caught you’ll most likely get in as much trouble as you would for a positive test.

But if you’re up for it, some people have had success hiding a small container of clean urine in their underwear, along with tiny nail clippers in their shoes. Once they’re alone in the bathroom, they use the clippers to cut a tiny hole in the container and then fill the cup with the clean urine. When they’re done, they hide all the evidence back in their shoes or underwear.

Other Types Of Marijuana Drug Tests

While urine tests are the most common cannabis tests, there are a few others you should be aware of. Some tests look for THC in your saliva. Cops use this one a lot. The good news for smokers is that THC doesn’t stay in saliva for very long. Usually, you’ll start turning up positive an hour after smoking and it’ll all be out of your saliva in 12 hours or less.

Hair follicle tests aren’t all that common because they can sometimes come back with false positives. Hair follicle tests can also be the hardest to pass. That’s because traces of cannabis can stay in your hair for anywhere from 7 to 90 days.

The last and least commonly test is a THC blood test. Employers and law enforcement don’t use this one very often since it only detects very recent use. THC-COOH doesn’t bond well to blood cells, so it doesn’t stay in your actual blood for very long.

The Final Hit

If you have to get tested for marijuana, it’s most likely that you’ll be facing a urine test. The problem for pot smokers is that these tests come back positive long after the high has worn off and they’re fully sober.

Since it’s usually pretty hard to cheat a urine test, your best bet is to understand how long THC-COOH will be in your system by using the timelines in this article. The more you can adjust your usage for an upcoming test the better.

In the end, though, it probably makes the most sense to try and avoid jobs that require drug testing. And in the meantime, it’s important for the cannabis community to agitate for marijuana drug tests to be eliminated since they don’t actually indicate if a person is impaired while on the job or not.

Even the most responsible cannabis user will still test positive for days or weeks after smoking. And when that happens they could be disciplined or cut off from a job, even if their cannabis use doesn’t affect their work performance in any way.
