How Long Does THC From Vaping Last in Urine?

How Long Does the THC From Vaping Last in Urine?

Marijuana is one of the most popular federally illegal drugs on the market. While some states have legalized it for recreational and medical use, other states are still stuck in the stone age. But regardless of whether you live in a free state or a state still under the grip of prohibition, it’s possible that your employer may require you to undergo a urine test.

While we can debate the merits of this backwards, privacy-invading practice all day long; the fact remains that drug tests are something that most of us will have to face at some point in our lives. So let’s get to the point: how long does THC from vaping last in your urine?

How does THC get into your urine to begin with?

Urine tests don’t actually test your pee for THC. What?

Despite the common misconception, urine screenings are actually testing for THC waste products known as metabolites. This waste product, which is known as THCCOOH, is what your body produces when metabolizing the THC from the marijuana you consume.

Your excretory systems are designed to remove waste metabolites like this from your body. To do so, the THCCOOH pairs up with glucuronic acid, which then leaves your body through your urine.

To sum things up: When you smoke weed, you’re inhaling THC. Your body then rapidly metabolizes it, getting you high. Your metabolism takes that psychoactive THC and turns it into non-psychoactive THCCOOH which you urinate out.

How long does THC stay in your urine?

We now know that urine drug tests aren’t actually testing for THC, but are instead looking for evidence that your body is eliminating the waste products that your body creates after THC consumption.

There is no way for the urine test to reveal when the last time you smoked was. It can’t determine whether you were high at the time that you took the test. All it can do is determine if your body is still working on eliminating the metabolite THCCOOH.

This makes it complicated to determine how long marijuana use is detectable in your urine. While we can’t give you a specific, straightforward answer; we can give you a rundown of the different factors that affect how long THC metabolites remain in your urine.

CBD products that do not contain any THC will most likely not cause you to fail a drug test.

Dosage

Researchers are fairly certain that about 15 to 20 percent of delta-9 THC (the marijuana component that makes you high) from each dose is eliminated via urine. What does that mean for your upcoming drug test?

It means that the more potent the bud that you smoke, the more metabolites that will end up in your pee. That’s how the person who administers your test is able to correlate the small amounts that they detect in your urine with a real dose of cannabis.

Usage habits

It may seem obvious, but if you smoke or vape more often there will be more THC that is detectable when you take your urine test.

If you’re using marijuana for the first time, your urine will most likely test clean within 5-8 days. If you’re a few-times-a-week smoker, then your urine will test hot for 1-2 weeks. If you consume marijuana most days but not daily, then it will be detectable for 1-1.5 months. Daily smokers can expect to test hot for marijuana for the next two months. So it all depends on how often you’re vaping cannabis.

To sum it up, here are the average detection levels. Keep in mind that these are averages, and your unique body composition and consumption habits can cause these numbers to vary wildly:

  • 1-time use: clean in 5-8 days
  • 2-4 times a week: 11-18 days
  • 5-6 times a week: 33-48 days
  • Daily use: 50-65 days, up to 77

Do Detoxification Programs Work?

There are detox programs available with home testing kits that can help you naturally cleanse your body and clear out the THC from your system before your drug test. The most popular kit is probably this one from TestClear.

There are also detox drinks that claim to help clear your urine at the last minute, keeping you clean for four-to-six hours.

Edibles vs. smoking

Does your method of cannabis consumption affect how long your urine will test positive for?

If you consume edibles, the THC will remain detectable in your body for longer than it would if you smoked or vaped instead. It’s not a significant difference, but it will stay in your system for up to a day longer than the reefer than you vape or smoke.

Your body processes THC differently when you eat it—converting it to a psychoactive metabolite called 11-hydroxy-THC, and then into the inactive THCCOOH the test detects—which means that you’re going to be at risk of failing a drug test for slightly longer compared to vaping or smoking pot.

Bottom line: how long does THC from vaping last in urine?

The bottom line is that marijuana stays in your system for a hell of a long time. If you know that you have a urine screening coming up soon, your best bet is to refrain from consumption until after the test so your urine sample comes back clean.

But let’s be realistic: that’s not always possible. Sooner or later, you might be needing a THC detox. So what is the best THC detox option for drug tests, detox kits or drinks?

Detox kits for drug tests vs detox drinks

Look: there are few things scarier than being told you’re about to be taking a drug test. This is universally true—even for lots of people who know they’ll test clean! If you have been using cannabis within the last few months, you’re probably even more worried–and rightly so! As you’ll see, those metabolites might be in your system for up to 90 days, depending on the facts.

You might not have an extra 90 days, but you do have choices. Here are the THC detox options.

THC Detox Options

Actually, THC isn’t a “toxin” in any sense of the word. But since we tend to think about drug tests and detox in the same breath, we’re sticking with “detox.”

However, the idea that you can just drink some juice and flush all of the THC metabolites from your system is nearly always wrong. Passing a marijuana urine drug test successfully typically requires a whole detox kit.

Intensive THC detox kits nearly always come through—even for daily cannabis users—without a single problem. Particularly for chronic users, kits are essential, because detox drinks simply are not enough.

Of course, for some situations the best detox drink to pass a drug test works like a charm. Read on to find out when to try these, in our opinion.

However, only two methods totally guarantee that you will pass a marijuana drug test:

  • Intensive THC detox kits. A 5 or 10 day intensive THC detox kit that combines detox fiber, liquid, and pills, instead of a detox drink. This kind of kit isn’t exactly fun, in that you’ll be on the toilet peeing and sh*tting a lot every day, but it works.
  • Synthetic urine. In absolute emergencies, lab-made synthetic urine is the way to go. Read about it here.

In this post, we’ll compare THC detox kits and detox drinks and explain why the kits are so much more optimal for beating the drug test. We will also highlight which situations are best for which methods.

Best detox kit for drug tests: Toxin Rid

Our number one choice for beating a marijuana drug test is the Toxin Rid detox kit. Read on to find out why.

Toxin Rid Review

When stepping into your dream job—or maybe staying out of jail—is one drug test away, passing that drug test is probably the only thing on your mind. As a daily, long-term user of cannabis, you already know it’s going to take months to detox, but you just don’t have that much time.

Toxin Rid 10-day detox is the only marijuana detox kit worth using. A vegan, all-natural blend of herbs, minerals, and vitamins, this kit is your best shot other than synthetic urine or abstinence.

A box of Toxin Rid 10-day detox contains:

  • 150 Pre-rid pills containing herbs, minerals, vitamins, diuretics to prompt urination, and electrolytes to replace those lost during all that urination.
  • One ounce of dietary fiber in the form of psyllium husk powder, a natural laxative.
  • One fluid ounce of detox liquid containing minerals and electrolytes.

Pre-rid pills contain:

  • Minerals including boron, calcium, iron, and magnesium
  • Electrolytes including chloride, potassium, and sodium
  • Alfalfa leaf extract, a fat burner and diuretic that helps capture metabolites in your body’s waste products
  • Kelp, which is rich in electrolytes and vitamins

The detox liquid contains:

  • Minerals such as boron and magnesium
  • Electrolytes such as chloride, lithium, potassium, and sodium

How to Use the Toxin Rid 10-Day Detox Program

The Toxin Rid 10-day detox program was created especially for frequent, long-term users of substances such as cannabis. However, it only works if you follow the outlined instructions rigidly. The 10-day program happens in three stages.

Stage 1: Pre-rid pills, days 1 through 10

Before you start, STOP using. (This should maybe go without saying—but we’re saying it anyway.)

  • Each day you must take three Pre-Rid pills with eight ounces of water every hour for five hours in a row. That’s 15 pills per day. You’re going to be in the bathroom a lot—both reasons.
  • Eat only whole foods, particularly those that are high fiber and lean protein. Don’t forget to drink plenty of water.
Stage 2: Detox liquid, day 10 (or whenever your last day is, if you added days)

Consume the detox liquid as directed on the final day of the program.

  • Take the last of your Pre-rid pills. Two hours later, drink half of the detox liquid with a mixture of sixteen ounces of distilled or filtered water and orange juice. Do not eat or drink anything for the next two hours.
  • Two hours later, take the rest of the liquid. Again, refrain from eating and drinking for two hours, but after that you can drink and eat as normal.
Stage 3: Dietary fiber

This is similar to Metamucil or something like that. It’s a powdered fiber you mix into water and drink.

  • Consume the fiber one hour before the drug test. To do this, mix the dietary fiber with eight ounces of distilled or filtered water. Drink within two minutes.
  • Wait fifteen minutes. Drink an additional sixteen ounces of water.
  • Do not drink any more liquids to avoid a dilution result.
  • Urinate two or three times in the next hour before the drug test.
Does the Toxin Rid 10-day detox program actually work?

According to numerous verified purchasers, yes. The key seems to be carefully sticking to the directions, and being honest about how many days you’ll need based on your use.

Does Toxin Rid have any side effects? Toxin Rid is all natural and safe, but since you’re going to be consuming a pretty serious laxative, you may be chained to the toilet. It’s safe to say that diarrhea may be a side effect.

Final Thoughts on Toxin Rid 10-Day THC Detox Kit

If you are a heavy/daily user of cannabis facing a drug test, Toxin Rid 10-day detox is among your best chances for success. It’s not cheap, but if you follow the directions to the letter and have enough based on a realistic assessment of your habits, you should do well.

Why Are Detox Kits so Reliable?

One of the biggest reasons that the full detox kits work so much better than the detox drinks is easy to get from reading reviews. Take a look at a few and you’ll quickly see that people who use these kits spend a lot of time on the toilet.

The pre-rid detox pills are what causes that, and they do an excellent job cleaning out the system, so to speak. Since THC is fat-soluble, this helps get it out of your body faster.

According to research, we defecate over 60 percent of THC metabolites out of our system. In other words, we sh*t the majority of cannabis out of our bodies.

Of course eventually they all escape. Detox kits just help them out more quickly. The pre-rid pills are designed to put your body into full-on bathroom mode, with the alfalfa leaf extract capturing and sending more metabolites to the feces that the body will soon be expelling like no one’s business.

Enough pills bring the number of days standing between you and a clean drug test down, even if you’re a heavy, regular user. The most important factor is candor. Be honest as you assess your habits.

For example, most of us here at VV are daily, heavy users, and we vape top shelf concentrates. This means no one here is going to find anything less than a 10-day kit helpful, just being realistic. Some of us will need to add days.

What’s going through the Toxin Rid 10-day kit like? Well, seriously, put things to read in the bathroom, and don’t fill up your schedule. It won’t work. But if you’re serious about passing your test, bite the bullet and get it done.

What Are the Best Detox Drinks for Drug Tests

Detox drinks for drug tests are sketchy. Depending on what you use, it’s a real risk relying on them. If you’re a cannabis consumer, for sure, detox drinks won’t always work.

However, if you can’t or won’t deal with a kit and want a natural alternative, there are some situations that detox drinks really work well in. Just remember this: all of those situations start with a person who is already close to passing the test.

In other words, if you’re an occasional user and it’s been awhile, this kind of drink may get you over the hump, buying you up to five days. But detox drinks, especially for marijuana drug tests, are not a full-proof THC detox plan.

The best detox drink comes into play when you’re right on that line, and finding the best is the difference between passing and failing. Here are the basics.

Always choose the larger size. If there are potency options, always opt up. Never bring a weaker detox drink to an imminent drug screening.

Final Thoughts: Detox Drinks vs Detox Kits for Marijuana

There are really only a few situations when you should trust detox drinks for marijuana drug tests. If you’re already a light user who is close to passing, this may be a good option for you. Weekend puffers may fall into this category.

Daily users, however, really need a detox kit. You should also opt for a kit if you tend to smoke or vape all day long, favor high-dosage edibles, or just like high-potency products.

Ultimately, no one wants to err on the side of cheaping out and failing a drug test. Yes, detox kits are expensive. But a detox drink is only a viable option if you’re really close to the safety zone right now.

If you have a urine drug test coming up soon, you may be wondering how long THC is detectable. It all depends on how often you smoke and your own body.

If I Smoke Weed Once, Will I Fail a Urine Test?

Many occasional smokers think they will fail the urine drug test because they smoked weed once before. Could this be true? The answer is complex. Therefore, read on, as we break down this question into smaller parts.

How Long Does Weed Stay in Your System?

Whether you smoke occasionally or are new to cannabis, having information about how your body reacts to weed is essential.

Marijuana contains THC (delta-9 tetrahydrocannabinol), a psychotropic or euphoric substance that stimulates part of your brain and causes a “high.” A drug test is not usually administered to detect the THC molecules in your urine but rather the waste products your body produces after smoking weed.

When you smoke marijuana, THC metabolizes in your body, which gets you high for a few hours as your body processes the psychoactive content. The end products, which are called metabolites, store in your fat cells and organs of your body from several days to several weeks until fully clean. The time it takes for the metabolites to clean from your system depends on how often you smoke, your metabolism, and the amount of fat you have in your body.

How Much You Need to Pass a Urine Test

A urine test is considered noninvasive and relatively accurate. Technically, weed doesn’t stay in your urine, but its waste products do. A urine drug screen for marijuana contains immunoassays with antibodies that are made to detect THC’s main metabolite 11-nor-delta-9 Carboxy-THC (THC-COOH).

The accepted cutoff level for THC-COOH in a urine test is 50 ng/mL, which means that your result is considered negative if you have less than 50 ng/mL; otherwise, it’s positive. When the initial urine screen is positive, a Gas Chromatography/Mass Spectrometry test will be used to verify the result at a cutoff level of 15 ng/mL.

How Much Is 50 ng/mL?

CarboxyTetrahydrocannabinol is the most abundant metabolite that stores in the system and ultimately the compound of interest during a urine test. According to studies, the average joint gives about 150–200 ng/mL peak concentration of THC-COOH in urine 4 hours after smoking. So, 50 ng/mL is about one-fourth or one-third of a joint, but it strongly depends on your cannabis potency.

THC Half-Life

Half-life is the time frame it takes for a substance to reduce by half its initial value. The half-life of THC is not the same as how long you stay “high.”

The half-life of THC in urine is about 30 hours, which means that THC concentration in urine is reduced by half about every 30 hours. So, having 200 ng/mL after smoking a joint will give you about 100 ng/mL the next day and about 50 ng/mL 2 days after smoking.

This calculation is very rough because half-life depends heavily on many factors, such as:

  • the route of administration
  • the frequency of marijuana use
  • body structure
  • drug potency
  • fluid intake
  • metabolism rate

Will I Pass a Drug Test If I Smoked 1 Week Ago?

Regardless of all the information about whether or not you will pass a drug test, it still depends specifically on your body and the potency of marijuana. In most cases, a week is long enough to flush THC out of your body. So, yes, if you smoked only once, you are very likely to pass a urine test after one week. After 2, 3, 4, and more weeks, chances are 100%, but 1 week is also close to 100%.

Will I Pass a Drug Test If I Smoked Weed a Few Days Ago?

The short-lived effect of THC does not prevent evidence of marijuana from lingering in your body. For as long as the chemical exists in your body, you risk failing a drug test. If you had smoked weed just a few days ago, your chance of passing is 50–50, depending on the potency of the marijuana and your metabolism. Having a few puffs will give you a THC-COOH level under 50 ng/ml in 1–2 days. After one joint, you can pass the test in 3–5 days.

Can I Pass a Drug Test the Next Day?

The time it takes for weed to get out of the system depends on how often, how much, and for how long the user has been smoking. If you don’t have a history of marijuana smoking and you had just a few puffs, it’s possible but not guaranteed that you will pass a drug test the next day. After a joint or even half of a joint, you will fail.

Can I Pass the Urine Test in a Few Hours?

Surprisingly, yes. As was said before, urine tests check for THC-COOH, not THC itself. THC-COOH is a metabolite of THC, and the body needs some time to metabolise THC into THC-COOH and excrete it through urine. According to studies, the peak concentration of THC-COOH in urine comes about 4 hours after smoking. So, 1–2 hours may not be long enough to accumulate 50 ng/mL in urine so that you can pass. This is why saliva tests are used to detect recent cannabis use.

So, the main question is:

Will I Fail a Urine Test If I Smoke Weed Once?

Several factors can improve or decrease your chances of passing a drug test. Studies have shown that occasional smokers can pass a urine test in a few days.

If you had just 1–2 puffs, the chances are that you will pass even the next day if your strain was weak.

If you had a full joint, you would fail in the next few days, but it’s impossible to say for sure how many days you would need to get clean. It depends on weed potency and your metabolism.

You will pass the urine test for sure about one week after smoking weed once.

Important Notice

This information is for only one smoke, not for regular users! Even if you had smoked a few weeks ago, some residue might stay in the body and affect test results.

The calculations above are rough. In the end, it all depends on weed potency and your metabolism! You should not rely on this information when preparing to pass a drug test.

To know if you are ready for a drug test, you need to be able to determine the number of metabolites in your urine. You can use the THC calculator to calculate your approximate level of THC-COOH. It also helps to understand the probability of passing a test.

When your chances of passing a drug test are slim or you are not sure about the result, use THC detox kits that clear THC metabolites from your system. They include high-quality detox drinks that will help dilute your urine. These detox drinks contain vitamin B and creatine that will help hide that your urine is diluted.

Many occasional smokers think they will fail the urine drug test because they smoked weed once before. Could this be true? The answer is complex.
