Whether you’re applying for a new job or your school requires random drug tests, taking a urine drug test if you smoke marijuana or use recreational drugs can be stressful—especially if you were given short notice. Luckily, it is possible to pass a urine drug test in 24 hours. In fact, there’s even more than one way to pass a drug test in a day!
Note that the options in this guide on how to pass a urine drug test in 24 hours do not apply to other testing methods, such as a hair or blood test. With that said, let’s get started.

While we will cover a few other options, the only sure-fire way to pass a urine test in 24 hours—or less—is to substitute clean urine. However, if it’s a supervised drug test, this method can be tricky and often requires a urine bladder, tubing, or an artificial penis (if you’re male).
Using Someone Else’s Urine
Your first instinct might be to use someone else’s urine, but keep in mind this route is fraught with potential risks.
First, you have to find someone you are absolutely sure does not use any type of drugs, prescription or otherwise, that can provide a clean urine sample.
Second, you have to maintain that sample. Real human urine degrades and grows bacteria rather quickly and will take on a cloudy, stringy appearance. The only way to keep the sample from going bad, so to speak, is to refrigerate or freeze it. Freezing immediately after collection is best.
Third, the urine sample has to be between 94° and 100° F when you submit it. Given you have to freeze it to preserve it, that’s a problem. You’ll have to reheat it to the correct range and then keep it warm. Plus, all of this is a bit awkward, being it involves someone else’s pee.
In short, while using someone else’s urine is one viable option to pass a urine drug test in 24 hours, it’s more of a last resort than a best option. What’s the best option, then?
Synthetic urine is the best option to pass a drug test fast. Unlike real urine, synthetic urine won’t change in appearance if left at room temperature.
However, it’s vital that the synthetic urine you purchase is from a reputable supplier. High-quality synthetic urine is formulated to mimic the chemical components of a real urine sample exactly—so much so that it can be used to test urinalysis equipment. Unfortunately, not all synthetic urine is high-quality. We’ll cover some good brands a bit later in this guide on how to pass a drug test in one day.
Synthetic urine does still need to be properly heated, but since the sample doesn’t begin frozen, a heating pad is usually sufficient. Many brands even offer kits with everything that you’ll need, including a delivery pouch with tubing and heating pad.
Flush THC From Your System
If you don’t have access to synthetic urine or your test is supervised, flushing your system is another option. We will caution that just drinking a ton of water is unlikely to work if you need to pass a drug test in 24 hours. If you have more time, it might, but it will take longer than a day.
To flush THC from your system, you’ll need to use detox pills, drinks—or both. The first step either way is to stop marijuana or other drug use (until after your test at least).
THC Detox Drinks
Sometimes called THC flush drinks, detox drinks are designed to remove, or flush, THC metabolites from your urine. Be aware that this effect is not permanent. It only lasts a few hours at best.
THC metabolites are stored within your body fat, meaning even if you discontinue use and flush your system, as you metabolize fat more will be released as waste and so end up in your urine.
Flush drinks will also make you have to use the bathroom a lot, which is actually how they work. You need to urinate at least three times before the test to make sure that any urine containing THC metabolites from fat metabolism is no longer in your bladder.
You’ll also need to drink plenty of water to replace that urine. Follow the directions of the product you choose to the letter as they often vary slightly from brand to brand.
Same-Day THC Detox Pills
Same-day THC detox pills work similarly to drinks to flush THC metabolites, but they are often more powerful. Many people also don’t like the taste of the drinks, and so prefer pill format.
However, we actually recommend using both if you aim to pass a drug test in 24 hours, especially if you’re a heavy marijuana user. Use a detox pill as soon as possible (preferably about 24 hours before the test) and a detox drink two hours before the test.
Again, be sure to follow the directions on the product you choose carefully and don’t overdo it. Overusing detox products won’t increase their efficiency.
Best Products to Pass a Urine Drug Test in 24 Hours
Having covered how to pass a 10-panel drug test in 24 hours—or any urine drug test, next, as promised, we’ll cover the best products to use for each method.
Top Synthetic Urine Products
Clear Choice Sub Solution
Made by Clear Choice, Sub Solution is pH balanced and contains B vitamins, creatinine, urea, and uric acid, among other ingredients, to mimic the appearance and chemical make-up of real urine. They regularly update their formula to adjust to any updates in the urine testing process.
We also love that they offer a heat activation powder that eliminates the difficulty of getting your urine sample the right temperature fast. It is undetectable even by a lab. If you’re looking for an easy-to-use product, Sub Solution would be our top pick.
You just pour a third of the heat activator into the pre-mixed urine and watch the thermal strip. Continue to add a little powder at a time until the sample is between 94° and 100° F. You can add more powder later if your sample begins to cool before submission.
The only downside of the heat activator powder is that if you add too much, you have to wait for the sample to cool down. If all this sounds complicated, Clear Choice even offers a practice kit bundle in their Official Site.
Monkey Whizz is one of the largest companies in the industry and maker of the popular urine device, Monkey Dong. They also offer a flask and the “whizz” pouch, a belt fitted with a sample container on the inside.
Much like Sub Solution, Monkey Wizz is formulated to match human urine exactly and has a solid reputation. However, their biggest advantage over other brands is the wide array of sample delivery options you can buy bundled with your synthetic urine. You can also get the urine in both powdered or pre-mixed versions. We consider it our top pick for those looking for versatility.
Using Monkey Whizz varies based on the synthetic urine type you choose and the kit, if any, selected. All the options do not include a heat activator and require a heating pad.
Quick Fix Plus
Another pre-mixed option, Quick Fix is made by Spectrum Labs. Like Clear Choice, they use a special blend to create artificial urine that is indistinguishable from the real thing. They even offer a money-back guarantee, proving that they stand behind their products—they have an over 99% success rate and are a favorite of heavy marijuana users.
A random sample is tested from every batch using a real urinalysis machine for quality control, and the formula is regularly updated (they are currently on version 6.2).
Unfortunately, like Monkey Whizz, they don’t offer a heat activator powder. You have to use a heating pad, but they do offer bundles that include everything you’ll need to pass your urine drug test in 24 hours. No mixing is required to use Quick Fix. You simply heat the sample in the microwave and keep it warm with a heating pad, or you can heat it exclusively with the heating pad by attaching it an hour before the time of your test and then keeping it close to your body.
While it’s not quite as advanced as some other brands on the market, Quick Fix Plus is our top choice for those looking for a budget option.
Top Detox Drinks and Pills
Also made by Spectrum Labs, Quick Clear is our top choice in the detox drinks category—sort of. It’s more of a combination product as it includes a 20-ounce drink and eight tablets. Quick Clear is not only reliable but also affordable. If you frequently have to pass drug tests for work, school, or otherwise, price matters.
Quick Clear is a bit more complicated than simply drinking a mixture and taking a few tablets. To use the product, you need to begin by drinking 20-ounces of water, followed by taking the eight tablets and drinking the detox drink approximately 20 minutes later. Don’t forget to shake the drink before consumption.
About 20 minutes after you finish the detox drink, you’ll need to drink 20 more ounces of water, meaning between the water and the detox mixture, you’ll need to consume 60 ounces of liquid within an hour. Keep in mind your average soda is eight ounces to put that in perspective. How much water you have to drink is one downside of Quick Clear—but it’s worth it. It works.
As you can imagine, with that much liquid intake that fast, you’ll need to use the bathroom more than usual. You should be able to pass a drug test within an hour of finishing the process but must take your test within four to five hours. Do not use drugs during this time.
Detoxify Instant Clean
Made by Instant Clean Herbal Cleanse, Detoxify Instant Clean is a detox pill, and our top pick as far as ease of use goes. It contains three tablets with a unique blend of herbs, vitamins, and minerals. Each tablet produces a different effect in the body, making it crucial to take all three.
First, take the cleansing-blend pill. This pill increases your liver and kidney function to help your body naturally remove drug metabolites like THC. Like Quick Clear, Detoxify Instant Clean also requires a lot of water intake. Each pill must be taken with 20-ounces of water.
About 15 minutes after you take the first tablet, take the second, known as the yellow nutrient pill. It contains vitamins and minerals. Lastly, take the final tablet, the blue one, which contains diuretics (herbs that will make you urinate).
Used properly, you should be able to pass a urine drug test within an hour of finishing the final pill, and the effects will last approximately six hours.
Detoxify Mega Clean
Also made by Instant Clean Herbal Cleanse, Mega Clean is a detox drink and has a slightly different formula. It has a long history in the detox market with over a decade of positive reviews from chronic marijuana users.
Like their Instant Clean pills, Mega Clean contains a special blend of vitamins, minerals, and herbs to help flush your system. That includes powerful options like Burdock root extract. Do not use this product if you don’t have access to a bathroom.
One of the biggest advantages of Mega Clean is that if you don’t even have 24 hours before your urine test, you can double up and use two bottles. Double usage is also recommended if you are a heavy or long-term user of marijuana.
Keep in mind that you must finish the drink at least three hours before your drug test. Each bottle is roughly 32 fluid ounces, and you will need to refill the bottle with water and drink it 15 minutes after drinking the detox mixture itself. The results will last around five hours.
Cheap Detox Products
You can, in cases, find detox products in retail stores, often in the diet section. These products should only be used as a last resort as many of them are not 100% effective. They might be better than nothing, but they certainly aren’t as good as the other products we’ve covered thus far in our guide. We will briefly touch on each, as many people ask us about their effectiveness.
STRIP Natural Cleanser
STRIP NC can be found at many retailers, including online options like Amazon. What makes this product suspicious to us is the manufacturer suggests it works by stimulating both urination and bowel movements.
While you do shed drug metabolites during a bowel movement, with drugs like marijuana where metabolites are stored in your fat cells, this would take a long time to be effective. Detox pills and drinks usually focus on urination only because the results are fast. Essentially, we’re saying you’ll be going number two a ton for no reason with this product. We don’t recommend it.
Most frequently found at GNC, Total Eclipse is a 32-ounce detox drink. While it has many ingredients found in more expensive brands, user reviews are not fantastic—marijuana users in particular, which suggests this option just isn’t powerful enough.
Rapid clear makes some bold claims. Namely, that it can allow you to pass a drug test for up to eight hours after use, which is longer than even the best brands on the market. Unfortunately, their reviews don’t back up that claim, and they don’t even provide an ingredient list to research whether their product is plausibly effective.
Another company slinging advertising that sounds a bit too good to be true, Optimal Kleen claims you don’t have to stop using your drug of choice between using their product and taking your drug test. For some, that may be a pretty big plus, but it’s also a massive red flag as that’s just not how the body works. Their reviews hoist the flag.
How Long Drugs Stay in Your System
Beyond the product you use, you also need to consider what drugs you’ve used and the duration those drugs stay in your body. Keep in mind that the ranges we give here are only rough estimates and can vary depending on a variety of additional factors.
While it’s one of the most common recreational drugs, unfortunately, marijuana is also one of the hardest drugs to flush out of your system. That’s because, as mentioned, it’s stored within your body fat. Even if you stop consumption, THC metabolites can remain present in your urine for weeks or even months as you metabolize new fat cells for energy.
If you don’t smoke marijuana frequently, you will likely be able to pass a drug test within three to five days of your last use. However, if you are a chronic user of THC products, including full-spectrum CBD, traces can be found for over a month. On that note, CBD isolates without THC can not lead to a positive drug test.
How long opiates stay in your system will depend on the type of opiate that you’ve consumed. For example, if you take codeine, it will likely appear in your urine for just a few days. On the other hand, methadone might last in your urine for up to a week. Most opiates are gone within this time frame.
If you are prescribed opiates, even temporarily, keep in mind that you need to provide your employer proof of that prescription, typically before your drug test.
Cocaine is another substance that won’t be detectable in your urine for a prolonged period. In most cases, cocaine will only last up to four days in your urine. Some people will test negative for cocaine after just one or two days.
That said, you can’t always expect these results. Do not risk failing a drug test based on statistics because you might be an outlier.
In a similar fashion to cocaine, amphetamines don’t typically last more than four days in your urine.
No matter what substance you’ve consumed, it’s important to note that different testing methods can detect drug use longer than others. For example, your blood and saliva will typically retain traces of a substance for less time than urine, but your hair will retain them far longer.
Home Remedies to Beat a Urine Drug Test Fast
If you’ve done any research at all prior to reading our guide, you’ve likely stumbled on many home or DIY methods to pass a drug test fast—and all of them claim to be the best way to beat a test. While many of these options are free or very low cost, some are down-right dangerous, and many don’t work. Here’s how not to pass a drug test:
While if you drink a lot of water, it will indeed help you urinate more, it’s unlikely to work fast enough or be effective enough for a clean urine sample. Drinking too much water too fast can also be deadly. Also known as water intoxication, excessive water intake can upset the electrolyte balance in your body, dramatically decreasing your sodium levels and leading to cell death.
Many people try to add lemon juice to their water or even drink it straight in an effort to add a detoxing effect. Lemon juice does have cleansing properties, but like water, it’s not powerful enough to cheat a drug test. Straight lemon juice can also upset your stomach acid and lead to ulcers.
The first of our options that does not actually have any sound reasoning behind it, baking soda will not detox your body at all—but it will result in nausea, vomiting, and diarrhea.
Pickle juice contains a fantastic mix of electrolytes and is a good, albeit interestingly flavored, option for use after a detox product. However, it will not allow you to beat a drug test on its own.
Apple cider vinegar has become something of a health craze in the cleansing market. However, it requires long-term daily use, and evidence is mixed to its effectiveness.
Vitamin B12 isn’t recommended before a drug test to help pass it. It’s recommended after using a detox product, and that often leads to some confusion. Some people try to take it by itself. B12 can be used to add color back into your urine. 50mg is sufficient. However, a high-quality detox product, such as those covered above, will contain B12 along with other vitamins and nutrients to keep your urine the proper color and your body healthy.
Niacin, frequently suggested with Goldenseal, is another slower acting option. It may even work if you have weeks before your test rather than days—but it also tastes horrible and can lead to diarrhea and serious stomach cramps if not taken with care. As these are not products that most of us have hanging around the house, and they can be expensive. You are far better off buying an actual detox product to beat your test.
Frequently Asked Questions
Can I pass a urine drug test in an hour?
If you have very little time, such as an hour or less before you have to take a test, the best way to go is synthetic urine. Most detox products take at least an hour to become effective. It’s best to keep some form of synthetic urine easily accessible if you are in a situation where you may be randomly selected for drug testing or be given very little notice.
For example, you can keep a powdered version in your glove box along with a bottle of water. Be aware of the storage guidelines for your desired product when doing so. Some do not stand up well to high heat.
How long is THC stored in fat cells?
Unfortunately, how long THC metabolites will be present in your fat cells varies on your usage levels, duration, body fat percentage, metabolism, and more. In most cases, it takes a month after ceasing marijuana use. Regular exercise, a healthy diet, and water intake can speed things along. Anything that helps metabolize fat will speed the release of THC from your body.
Does cranberry juice help you pass a drug test?
The most common question we receive, beyond how to get drugs out of your system, of course, is regarding the effectiveness of cranberry juice in helping to pass drug tests. It’s not so much recommended as a DIY method, and so we didn’t list it above. On the contrary, we’ve been told daily consumption of cranberry can help you pass a drug test anytime, and that is 100% false.
There is no doubt that cranberry juice offers a detox effect for those who drink it or take supplements. As a diuretic, it can help you pass urine through your system and rid your body of unwanted substances. It’s wonderful for preventing urinary tract infections. Still, there appears to be no concrete evidence that cranberry juice can help you pass a urine drug test at any time, let alone all the time. Even if cranberry juice does slightly improve your ability to remove drug metabolites like THC from your body, it is important to note it offers no guarantees when it comes to taking a test.
Can a urine drug test be wrong?
There is a false assumption that urine drug tests are infallible. In reality, urine drug tests can provide both false negatives and false positives. While false positives are rare, it’s important to note that it is possible, especially for certain types of drugs, for example, CBD users sometimes test positive for THC.
Additionally, some urine tests can also miss drugs if you’ve consumed them shortly before your test. While this is not always the case, it is a notable shortcoming to consider.
If you fail a urine drug test and you have not consumed any drugs, you can certainly request a second test. If you fail and you have consumed drugs, you might ask for a retest anyway and try a different cheat method. It’s worth a shot. Though, it’s probable if you are given a second chance, that test will be supervised.
The reason you don’t see many false positive—and the reason retests aren’t common—is that drug testing facilities usually perform two tests on positive samples. For example, they may require an initial immunoassay test. If this comes back positive, they will request a GC/MS test to confirm those results. The drug testing process has a very low margin of error if done in an actual lab.
Is it legal for them to supervise me pee during the test?
Supervised drug tests are legal, yes. Also known as direct observation collections, supervised urine tests have been challenged in several states, and laws do vary by state on when a supervised test can be legally given, but they are not illegal.
Test administrators must also adhere to strict guidelines. They are in the room, yes, but they will not be staring at your privates. We recommend that you ask your testing facility what to expect in advance if you are asked to take a supervised test. Not necessarily to improve your chances of passing, but to relieve any anxiety you may have about someone being in the room while you give your sample.
Roadside Drug Testing: How to Beat It
If you come across an unfortunate roadside drug test, you will have entirely different circumstances to navigate—you won’t have hours you’ll have minutes. Luckily, roadside drug tests don’t typically involve the type of urine tests that we’ve referred to throughout this guide.
The primary purpose of a roadside drug test is to determine if you are currently under the influence of a particular substance, usually THC. A urine test that assesses previous substance use would not be effective.
Most roadside tests inspect your saliva for traces of THC and other substances. Unlike urine tests, your saliva won’t typically hold traces of THC for more than a week, and in most cases, unless you have used recently (same day), you will pass. There are some rinses you can use to avoid a positive result, but keep in mind that you may not have the opportunity or time to use them if the officer never leaves your window.
If you do test positive on a roadside drug test, you’ll immediately be taken to a police station to get a blood test. None of the methods detailed here will work for a blood test. Why don’t we have a guide on how to pass a blood drug test in 24 hours? Because it would be a short guide, you just stop any drug use.
If you are searching “how to beat roadside drug testing NSW” from your car, our top recommendation is to not use any type of drugs before driving, including marijuana. Driving under the influence puts you and others at risk.
Wrapping It Up: How to Pass a Urine Drug Test in 24 Hours
Whether you’re trying to remove THC or other drugs from your system, preparation pays. While 24 hours leaves you with an extremely small window of time to cleanse your system from drugs, it’s essential to put in your best efforts if you want to avoid failing a test. The methods outlined in this guide will help you increase your chances of passing a drug test in a short amount of time.
While there are different ways to pass a drug test, make sure to remain as safe as possible. If you’re planning to drink a lot of water or consume any other type of detox drinks, always avoid overconsumption. Additionally, we do not recommend using unproven home remedies, especially if there are potential health implications.
Lastly, as technology progresses and cannabis becomes legalized across the country, more resources will be funneled into helping people pass drug screenings—and we’ll be updating our info. Check back as frequently if you want to discover new products and methods to help you pass a drug test fast.
