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.


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.


More and more people are experimenting with cannabis vape cartridges. For vape enthusiasts, using a cartridge provides a level of convenience along with a way to control the dosage. And it makes consuming the plant more discreet than smoking a joint or pipe is.

For first-time or infrequent cannabis consumers, the care and use of cartridges can be a bit confusing. And many people wonder how long a cartridge will—or should—last them.

Let’s break down the basics of marijuana vaporizer cartridges to understand how long a vape cartridge may last for you.

A Quick Marijuana Vape Pen Primer

Many people are discovering cannabis concentrates. The sales numbers for these golden-colored oils are racing ahead of that of cannabis flowers for several reasons:

  • There are typically higher levels of concentrated cannabinoids in extracted cannabis oil vs. that of marijuana flower.
  • Unlike smoking cannabis flower from a pipe, bong or in a joint, vaping cannabis concentrates means you aren’t combusting cannabis plant material. This is healthier for the lungs and also helps keep the healing cannabinoids intact.
  • The exhaled marijuana vapor has very little scent. And the far-less-pungent smell from a vape pen, as opposed to the odor of combusted cannabis flower, dissipates almost immediately.
  • Standard vape pens are discreet—generally resembling a slightly thick pen, making them easy to carry and store.

Reusable marijuana vape cartridges screw into a rechargeable, lithium ion battery that powers a heating element, resulting in vaporization and not smoke. High-end reusable vaporizers can come with temperature controls and even adapters to be able to vaporize marijuana flower as well as oil.

Disposable vape pens are another widely available option. The cartridge and pen are a single unit, and you don’t recharge them when they’re empty. You simply recycle them.

Most folks who are new to vaping cannabis start out with the least expensive option, which is usually a disposable pen. Once folks appreciate the benefits and convenience of vaping, many opt to buy higher-end pens, and there are virtually no limits on the type and design of vape pens available to consumers.

Extraction Techniques to Make Cannabis Concentrates

To produce concentrates, manufacturers extract cannabis oils from the leaf material and, depending on what the manufacturer desires as their end product, there are a number of extraction techniques they use to create the oils.

Distillates are cannabis oils that have been taken through a vacuum or steam process, usually several times, in order to isolate particular cannabinoids such as tetrahydrocannabinol (THC) or cannabidiol (CBD).

The end-product has very little flavor or smell, which allows concentrate manufacturers to modify the original solution so that they can create unique products. Companies sometimes add terpenes and flavors to distillates to enhance both their aroma and effects.

What Else Is in My Cannabis Vape Cartridge?

Once they extract the oil, cannabis concentrate manufacturers use a variety of techniques to create their final product.

For cartridges, the oil must remain viscous (have a thick and sticky consistency) in order for it to turn into vapor when properly heated and so that the concentrates don’t gum up. This can involve mixing raw cannabis oil with other additives, including:

  • Coconut oil
  • Vegetable glycerin
  • Propylene glycol

Some cannabis concentrate connoisseurs avoid carts containing additives, but you’ll have to decide what kind of vape cart is right for you.

How Much Cannabis Oil Is in My Cartridge & How Long Will It Last?

Generally, prefilled carts come in two sizes:

  • 1/2 gram (500 mg)
  • 1 gram (1,000 mg)

Unfortunately, there’s no standard formula for how many puffs your cartridge will contain. But according to a few dispensary employees, it’s comfortable to assume that the average person will reliably yield no less than 75 and probably no more than 150 puffs from a 1/2-gram cartridge. This is based on a 3-to-5-milligram puff, which varies widely from person to person.

That said, these are just a few of the variables when it comes to how long a vape cart lasts:

  • The temperature of the battery
  • How long and how much vapor you inhale
  • Whether you’re using a disposable or rechargeable battery

Using the 3-to-5 milligram formula, it’s fairly simple to make an educated guess as to how long a cart may last for you. If you’re a light inhaler and you’re using your vape pen throughout the day, taking around 30 puffs, your cartridge will probably last somewhere between three to five days.

A HelloMD interview with Jeff Nagel, co-founder of W Vapes breaks down how his company has determined how long its cartridges lasts.

Meanwhile, just remember: The percentage of THC in a cart doesn’t necessarily translate to the best cartridge for you. Effects from terpenes are often as important as the overall potency of the product is.

How to Get the Most Out of Your Cannabis Vape Cartridge

Here are a few tips to help maximize your cannabis cartridge experience:

  • Store your carts vertically, preferably in a cool, dry location. Heat will evaporate the oil in your cartridge.
  • Hold your pen vertically (not horizontally, the way you’d smoke a joint) when vaping.
  • No vapor? Try turning the cartridge upside down so that the oil coats the wick.
  • Use a cotton swab dipped in alcohol to clean your pen.
  • Dispensaries or delivery services will almost always replace a leaky cartridge. If your cart is leaking, don’t leave it on the battery as the oil could damage it.
  • For reusable vaporizers, unscrew the cart from the pen when not in use.
  • Use the rubber tips that come with the cart to keep the ends from leaking onto your backpack, purse, clothing or storage container.
