How to Pass a Drug Test in 24 Hours

We’ve investigated just about every method to rid your body of marijuana before taking a drug test. We found things that work exceptionally well, and other methods that didn’t work so well.

As you read about each possible method to pass a drug test, you will be able to form your own opinion as to which way is best for you.

You’re facing a drug test, and you’ve smoked marijuana recently.

This is never a good feeling.

Your mind races as you try and think of ways to get rid of the THC in your system.

Some might suggest you use a home remedy to detoxify your system but is that the safest choice? What is the very best way for you to completely rid your body of THC metabolites?

How long does marijuana stay in your system?

Marijuana, or THC, can stay in your system for up to 45 days after you’ve used. However, there are many factors involved in determining how long it will take you to get clean. Since everybody is different, certain methods will work better for some of us than others.

If you are a frequent user, you can expect the THC to stay in your system for longer after you quit. If you’ve just smoked just a little one or two times, your system will likely be clean in a shorter amount of time after you stop.

It is said that if you exercise frequently, drink a lot of water, and eat right, you can eliminate traces of THC much faster. Of course, that requires putting out the effort to get up and do all of that. There are easier ways to get clean.

Basics of the Urinalysis

When you are taking your drug test, you may be in a variety of environments. Some employers do on-site testing, where they will test you on the spot, without warning. In this case, a lab technician works with your employer to gather urine samples from all of the employees.

While on-site testing does exist, workers being sent off-site to specialized drug testing labs is becoming very common. When you go to a testing facility, you will be asked to empty your pockets, and they may pat you down. You will need to show ID, and proceed into the testing area to fill your sample cup with urine.

After you give your urine sample back to the lab technician, they may test it immediately. Whether they give you your results immediately or not is a different story. Sometimes employers collect multiple samples and test them at a later time. Do not make a big deal about getting your results at the time of the testing, as this could arouse suspicion.

How Do I Eliminate Marijuana From My System?

For you to know how to get the THC out of your system, you must first understand where it is. THC metabolites absorb into fat cells all over the body, making it tough to eliminate, without working out very hard.

Knowing the THC is mostly stored in fat cells, the best method is to attack those very fat cells. There are multiple ways to achieve this, but the basics involve eating a healthier diet, drinking lots of water, and exercising regularly. Supplements can be taken to more thoroughly detoxify the body and give you a better chance at passing.


Detox Methods That Work

(7-day cleansing program)

What Doesn’t Work

Cranberry Juice

Many people have made claims that drinking cranberry juice has helped them to pass a urine test. As it is commonly known as a diuretic, cranberry juice alone cannot eliminate THC from your system. While it is quite possible that cranberry juice could mask the THC metabolites, many of today’s tests may show an ‘inconclusive’ result.

If your test comes back ‘inconclusive,’ then you will be asked to retake it. For that reason alone, drinking cranberry juice is probably not the most effective solution for passing a urine test.

Cranberry juice can be very effective for flushing your system in general. It won’t hurt to drink some cranberry juice along with drinking plenty of water. Just don’t expect that drinking the juice alone is going to make you pass your piss test, because it’s not.


Some people believe that goldenseal, a bitter herb, will strip the THC metabolites from their bloodstream. The theory is that when mixed with Niacin, the two combined flush the body free of all toxins. While goldenseal is known to have other medicinal properties, eliminating THC is not one of them.

Another issue to take note of is the taste. Goldenseal is probably the most disgusting thing you will have ever tasted. It is bitter beyond belief. The problem with this is that even when taking a goldenseal pill, you have something that tastes and smells disgusting inside of you. It is going to come out. When you compare the taste and possible side effects of nausea and diarrhea, it isn’t worth it.

If you eat lots of goldenseal not only can you hurt your stomach, but your urine test will likely be determined to be inconclusive.


Niacin gives the body a flushed feeling, and when taken along with goldenseal, is said to rid the body of toxins. True as this may be, it doesn’t mean that 100% of the THC will be eliminated from your system.

Taking Niacin can give your skin a tingly feeling, but that doesn’t mean it’s burning away THC. Taken alone, it cannot make you pass a urine test. When mixed with goldenseal, your most likely outcome is an inconclusive result. Then you will have to test again.


One could potentially alter test results using bleach, through one of two methods.

The method that is sure to eliminate traces of THC is to add the bleach to the sample. While it is true that it will remove the THC, this method proves difficult because you will always need to have bleach handy. Further, it is widely known and screened for, so your result will likely be inconclusive.

Other people believe that drinking the bleach will help them to pass a drug test. There is zero evidence that this is true. What’s worse is that drinking bleach can be extremely harmful, and possibly fatal. Drinking bleach is one of the most unsafe methods to try and pass a drug test, and therefore is not recommended.


Some folks believe that drinking vinegar, particularly apple cider vinegar, will help them to test negative for THC on a drug screening. While vinegar is known to work as a detoxifying agent, whether it can remove, or hide the THC from a drug test is another story.

For drinking vinegar to be an effective solution, you would need to drink the right amount several times per day for a week or more. Not only is this an unpleasant experience, but it also has uncertain results. Not only is it uncertain whether your urine will test positive for THC or not, but you also have a chance of blowing the test. When you drink apple cider vinegar, it changes the pH in your urine. This alone can be detected and will mark your test inconclusive.

Drinking vinegar daily, for a week even possibly more, might hide your THC on a urine drug test. The problem is, you are not going to have the correct pH. Most likely, this will require you to retake the test.


This method involves mixing a full packet of Surejell, or Certo Fruit Pectin with Gatorade and a full gallon of water. Surejell is pectin, commonly used to make jelly or preserves. This method grabs all at the THC in your stomach lining, and passes it through your bowels. While unable to completely rid your system of THC, the Surejell method is said to provide a ‘window’ where you can test negative for THC.

Unless you know exactly when and where your next drug test will be, the Surejell method is not a viable one for you. Since it involves significant preparedness beforehand, it simply isn’t realistic for someone needing to pass a urinalysis right away.

If you know exactly when your drug test will be, Surejell might be a decent solution. However, you must be able to stomach gulping down over a gallon of the mixture. Odds are, you might experience an upset stomach when attempting to use this method.

Ginger Root Tea

While some believe that drinking ginger root tea will allow you to pass a drug screening, this has yet to be proven. This method is almost identical to drinking water, as people who have claimed it successful also drank well over a gallon. While ginger is known to have strong health benefits, elimination of THC from your system is not one of them.

To date, no significant findings have shown drinking ginger root tea alone to hide the presence of THC from a drug test. Those who have claimed success with it also drank other cleansing agents. If you need to pass a drug test, it is not advisable to rely on ginger root tea alone.

Creatine Pills

Alone, taking creatine pills before a drug test will do nothing more than mask the results. Taking creatine does not block THC from appearing in your urine. Drinking a good amount of water before, and with your creatine supplements can help give your diluted urine a more realistic look.

While creatine does have it’s used, taken alone is not going to be enough. Most of the time someone is employing a strategy involving creatine, they are also diluting (drinking 1+ gallons of water). In addition to properly hydrating and taking the creatine, one would also be wise to take vitamin b12.

If your urine sample is clear, they may accuse you of dilution and make you take the test at another time. For this reason, taking b12 supplements along with the creatine is critical to giving the urine a natural color. Even taking all of these steps, this strategy still isn’t 100% surefire.


Taking a zinc supplement before testing is a popular method, and if executed correctly, may work. However, like many of the other solutions available, the presence of zinc may be enough to trigger your test as ‘tampered with.’ If you are fortunate enough to have a marijuana test that does not look for zinc, taking a zinc supplement may be a good solution.

In addition to taking the supplement, you are going to need to abstain from smoking and properly hydrate. The supplement should be taken 2-4 hours before your drug test is administered.

Naturally Kleen Herbal Tea

If you can find it, Naturally Kleen makes a detoxifying tea that works well. You make a full gallon of the tea and drink it slowly up until before your test. While proven to be very effective with its unique blend of herbs, this tea is typically not a viable solution. Most stores stopped carrying it, complaining of it being shoplifted.

Something else to consider when drinking the Naturally Kleen detoxifying tea is the actual time of your test. You are going to be so full of liquid, and ready to go. If you go to a lab and there is a long line in front of you, you’ll be squirming while waiting for your turn. If you ask to go early, the technician administering the test may get suspicious that you drank something.

Baking Soda

Some had reported that drinking a mixture of baking soda and water before a test was successful. This method is questionable because eating a bunch of baking soda isn’t good for you. Also, the method’s popularity amongst those trying to pass a screening for methamphetamines does not give it a good reputation.

For those attempting to pass a urine test using a baking soda technique, be warned that it will likely fail. Drinking an excess of baking soda will increase the pH in your urine to a noticeable level. If it looks abnormal, the test conductor may ask that you retake the test at a different time.


For those looking to pass a drug test by drinking alcohol, stop here. It will not improve your chances at all. Drinking lots of water and exercising are the best ways to rid your body of toxins. Drinking alcohol does not have a detoxifying effect, rather the opposite.

You can be tested for alcohol just as easily as you can be for marijuana, so drinking booze before you take your test is not a good strategy. Instead of drinking a bunch of beer and risking getting caught for it, why not drink the same amount of water? It will flush your system better and eliminate the possibility of getting caught for drinking.

Eye Drops

Not only must you pass the urine test, but you must also appear sober. If you go into the lab to take your drug test, and your eyes are fiery red, the administrator is going to notice. With so many great eye drops on the market, a great solution is sure to be close by.

Products like Clear Eyes™ and Visine™ have been around for ages, and are generally acceptable for reducing redness. If your eyes are red, it may take multiple applications before you notice a feeling of relief.

For superior redness relief, try Rhoto-V eye drops. Multiple varieties are available, but the two kinds that seem to be the most popular and effective, are the ones with the blue or green lids. At first, you may not like Rhoto-V due to the tingling sensation it can give. However, you will soon realize that the sensation is bringing the whiteness back to your eyes.


If used along with drinking a lot of water, taking a 10-15 minute sauna can help to rid the body of unwanted toxins. Being in the sauna causes you to pour out sweat quite rapidly, so it’s important to remember to hydrate. Try to bring a gallon of water into the sauna and finish it before you come out.

While undisputedly an effective method for purging toxins from the body, taking a sauna alone won’t ensure that you pass your drug test. Even with drinking the gallon of water, it still isn’t enough to know for certain that you will pass. It definitely helps, but it’s not a sure-fire method to cleansing your system so that you pass a drug test.

How to Cleanse Your Body of Marijuana Naturally


Many people believe that simply by drinking a lot of water, they will pass their urine drug test. While this method seems logical, it simply isn’t enough to completely rid your body of toxins. You would have to drink so much water that you would be putting yourself at risk for water intoxication, which can be fatal.

When you drink a large amount of water in a short time, it causes the sodium levels in your body to drop substantially. In short, if you drink too much water too fast, you could get very ill, or even die. For this reason, drinking excessive amounts of water in a short amount of time is not recommended.

Being filled with all that water is also going to present you with two problems:

  1. You are going to need to pee really bad, constantly, until you take your test.
  2. When you do take your test, your system may be flushed so much that it will make your test results inconclusive. This is due to all of the vitamins and minerals that would normally be in your urine being flushed out and replaced with diluted urine.

Leafy Greens

While certain leafy greens are said to contain detoxifying qualities, their effectiveness in passing a drug test is unknown. Eating greens such as spinach, kale, or bok choy are recommended on days leading up to your drug test. Eating them alone won’t make you pass your whiz quiz, but those vegetables are high in fiber and will help you pass the THC faster.

No matter if you eat pounds and pounds of it, eating leafy greens alone will not make you pass a drug test. So if you are going to incorporate some spinach or kale into your diet, do so with moderation. There is nothing to gain by stuffing yourself full of greens, other than it will make you need to go to the bathroom.

Another benefit to eating leafy greens for the days leading up to your urinalysis is that you will give your urine color. If you are drinking lots of water to try and flush your system, eating lots of spinach or lettuce would be beneficial. This way, your urine will have a natural color to it, and not come across as too diluted.

Since leafy greens are high in fiber and contain vitamins A, C, and K, you should be eating them anyways. So while you use them strategically to pass your pee test, you are also giving your body essential nutrients. Eating leafy greens is recommended by health professionals worldwide.

Lemon Juice

Drinking lemon juice is said to help in cleansing your system for a drug test. How much, of what purity, and how frequently are some of the questions we need answers to. While drinking lemon juice alone is not commonly known to allow you to pass a drug test, it has its benefits.

Lemon juice gives aid in some ways. For starters, it helps with digestion and detoxifying. It also helps to rejuvenate your skin, and elevate your mood. Being that lemons are an alkaline food, drinking the juice balances your pH, which helps to protect your immune system against viruses.

Drinking pure lemon juice is not advised, as not only is it very sour, it can make you sick. You will want to add lemon juice to purified or distilled water. It is to your preference how much lemon juice you add. It goes by taste. You want to add enough that you can taste it, but not so much that it makes you gag.

There are multiple ways you can get lemon juice into your water. Easiest is to buy lemon juice concentrate at the grocery store. However, this has its drawbacks as some nutrients are lost in the pasteurization process. What is recommended is squeezing fresh lemons, and capturing the juice from those. Organic lemons are preferred, although any fresh lemon will do.

If you’re drinking lemon juice with hopes of passing the urinalysis, you need to drink as much as possible beforehand. Drinking lemon juice with purified water for several weeks is advisable. Please note that this method alone will not ensure you pass your test, it just improves your odds.

Say No to Junk Food and Red Meat

If you’re trying to get clean for that upcoming urine drug test, you want to cut out specific foods. Since THC metabolites stick to fat cells, you want to minimize the number of fatty foods you eat. Some foods are worse than others, but there are a select few that simply must be avoided.

Fast food is typically the worst culprit. Even though that burrito or hamburger looks delicious, you must use your willpower and not give in. Most fast food dishes are cooked in grease, use cheese and sauces, all high in fat. This is the stuff that the THC is sticking to and passing in your urine, so don’t fill your body with it.

Eating red meat should be avoided before taking a urine test. This type of protein is harder to digest and eliminate from your system, so the THC metabolites can cling to it for longer. You want anything with a trace of THC out of your system, so eating red meat or other fatty foods should be avoided.


For some, drinking a specific tea can help to cleanse the system of impurities. There are various teas on the market that claim to have antioxidant properties. Some are known to be quite reliable, but others have been found to show THC-positive test results still.

One tea that works particularly well is called Naturally Kleen Detoxifying Tea. While this tea does a good job of temporarily cleaning your system, it is hard to come by. Another issue with this tea (and many tea-based solutions) is that you need to take a lot of it. Naturally, Kleen recommends you drink at least one full gallon of tea before testing.

Other teas that are often mentioned when it comes to purifying your system are green tea, mint tea, and teas containing burdock root. While green tea is not known to make you pass a drug test all by itself, it does carry powerful antioxidant properties. Burdock root is known for its ability to purify the blood, so teas that contain this ingredient may be helpful.

No matter which type of tea you decide to drink, you are going to have to drink a lot of it. One gallon is the minimum amount listed by anyone using a tea-based detoxifying strategy. For this strategy to be effective, you absolutely must know when you will be tested.

Healthy Fiber

Eating lots of healthy fiber is another good measure to take before testing for marijuana. Fiber helps your system to pass things along. While this strategy alone will not ensure that you pass your test, combined with other detoxifying strategies, a high-fiber diet might prove helpful.

Psyllium husk is a great source of fiber and is usually not too expensive. This grain-like substance can be found in health food or bulk grocery stores. It is easiest consumed by mixing into fruit juice or blending into a smoothie.

Foods that are naturally high in fiber like beans, peas, berries, and mango are beneficial to eat as well. Avocados are naturally high in fiber, as are broccoli and brussels sprouts. For a high-fiber breakfast, try mixing flaxseed into your oatmeal, and topping with raspberries.


Some people believe that taking diuretics (pills that make you urinate more frequently) can help you to pass a marijuana test. The same line of thinking goes for diuretics as it does for drinking cranberry juice. The goal is to flush your system, but that alone won’t eliminate the traces of THC metabolites.

Some people have reported that taking diuretic pills like Midol™ before testing helped them to get a negative test result. However, those same people also drank over a gallon of water and supplemented with vitamin b12 and creatine.

It is important to note the danger in taking too many diuretics. In some cases, over-ingestion of common diuretic pills caused patients to suffer liver damage and even death. When you weigh out the risks versus the reward, taking diuretics to pass your drug test is not worth it.


Eating breakfast during the day of your drug test is important. Not only will that meal give you the energy you will need during the day, but it will also provide you with much-needed vitamins. If you have been hydrating, your urine could be too clear, causing an inconclusive result. Eating breakfast ensures there is more than just water in your stomach (and in your urine).

Healthy Diet

Maintaining a healthy diet can help increase your chances of passing your drug test. By keeping fat intake to a minimum, and instead of eating fibrous foods, you are helping your body rid itself of toxins. It can be tough to stick to it, but a healthy diet can help remove the THC metabolites from your system.

Foods like fresh fruit and vegetables are recommended, as they are high in fiber, low in fat, and contain lots of vitamins and other antioxidants. For starch, try whole-grain pasta and bread. Bran flakes or oatmeal is good for breakfast.

Some safe meals for dinner include grilled chicken or fish with light seasoning. Vegetables or a fresh salad will make a nice side. If you eat rice with dinner, try whole grain rice as it will likely be higher in fiber.

Remember to avoid foods like beef, pork, or anything ‘heavy.’ Those foods that take your body longer to digest also hold onto those THC metabolites that you want to eliminate. By avoiding foods that are high in fat, you increase your chances of passing your drug test.


If you have more than a couple of days before you need to test, getting a good workout can help to rid your body of toxins. Just about any workout is beneficial, but cardiovascular exercise is preferred. You want to get your heart rate up and work up a sweat.

Some of the best forms of cardiovascular exercise can be accomplished with little to no equipment. Running, or jogging, is a great way to get a workout, and you don’t need anything else besides a comfortable pair of shoes. Aerobics, gymnastics, boxing, and swimming are all great ways to get a cardiovascular workout.

Remember, the goal is to sweat out impurities and toxins. For this reason, it is advised that you do not exercise on the day of the test. It’s ok to work out leading up to the test but try not to work out on test day. On test day, you want to be well-hydrated. When you work out, you are constantly losing fluids, so on test day, skip the workout and instead, drink extra water.


The most foolproof method of passing your drug test is by not taking drugs, to begin with. Of course, you probably wouldn’t be here if you didn’t smoke some marijuana. While stopping the ingestion of THC is advisable, stopping alone won’t ensure that you pass your test.

To completely rid your body of THC metabolites, stop your consumption of marijuana for at least 30-45 days. If you are a heavy user, it may take longer than 45 days. If you only took a puff from one joint, you might be able to cleanse your system much sooner. Also, the size, weight, water consumption and diet of the user will factor into estimated time until clean.

On the Day of the Test

When the day comes that you will need to take your marijuana test, it is important to follow these important tips:

  • Eat a good, healthy breakfast. Having food in your stomach is good.
  • Drink plenty of water.
  • Check the color of your urine. If it is too clear, try taking b12 or b2 supplements.
  • Do not exercise.
  • When you take your test, use urine from ‘mid-stream.’ This means you should pee into the toilet a little, then pause and fill the cup. This takes urine from the middle of your stream, which is more likely to be free of toxins.

Substituting your Urine

Some people prefer to try and bring somebody else’s urine, instead of providing a sample of their own. While this may work, you must go about the task of asking for and collecting the clean urine. You are also taking a risk because you are carrying urine on you. If someone finds it, you’re in trouble.

Synthetic urine is another viable option, but it comes at a cost. Depending on where you buy it, you may pay anywhere from $20 to $40 for passable urine. Glass shops or smoke shops will sometimes carry it. You may have to ask someone behind the counter to get it for you; it isn’t always out on display.

One could easily obtain synthetic urine via online ordering, but then you have to wait for shipping. If a postal inspector sees synthetic urine, they will most likely seize it. What’s more, is if your employer catches you with fake pee, they will almost certainly fire you.

Another downside of both using other people’s urine or synthetic urine is that you need to keep it at the right temperature. If your urine sample is not warm or is strangely hot, you will be flagged and possibly asked to test again. It’s a risk to carry it around with you all the time.

Some people even go so far as to collect urine from their dogs to try and use on their upcoming drug test. This method is a disastrous failure. Animal urine and human urine break down differently and will be noticed by the lab. Please don’t involve your animals in your drug testing.

If you decide to go down this road and carry a urine substitute on you, you must be able to keep it warm. Hand warmers are the most common and convenient solution. You microwave your synthetic urine for 15 seconds, then use a rubber band to strap it to your leg. Activate the hand-warmer and place next to the urine, and you will have passable urine for up to 8 hours.

It’s critical not to be seen with your synthetic urine. Don’t tell anyone you have it. Just keep it close by, but well hidden. If you aren’t carrying it and someone asks you to take a drug test, you will need to get to it easily. If you ask to leave, you will look suspicious and will possibly be searched upon return.

False Positive

There are several ways that you can accidentally fail a drug test. Below is a list of substances that are known to trigger a positive result on a drug test.

  • Poppy Seeds. These can trigger a positive for opiates, so it’s wise to go without.
  • Advil (ibuprofen). This common pain reliever can trigger a positive for marijuana.
  • Tonic water. If you drink a lot of tonic water the night before, you can test positive for opiates.
  • Protonix. This prescription heartburn medication can easily trigger a positive for THC.

Getting Caught

If you are unable to pass your drug test, it may cost you your job, or even your freedom. Professional drivers will lose their position immediately if caught with drugs in their system. If you are on parole and you get caught, you are required to go to jail.

Since the consequences are so severe, it’s important to remember one thing: Don’t get caught!

Why is Drug Urine Testing Wrong?

Besides the fact that it’s scary and unpleasant, urine testing is wrong for other reasons. It violates our privacy, which we do not agree to do when taking a job. Drug tests are also notorious for being inaccurate. Finally, they are pointless. Every day, millions of people smoke marijuana and go to work, operating completely fine.

Although philosophically urine testing is wrong, we still must respect that it is still widely used. Either we adapt, and become able to pass the test, or risk losing our livelihood.


There are all sorts of ways you can try and clean out your system. What’s the best for you? If you are serious about passing your test, you will do what it takes to accomplish this. Stopping smoking, eating right, drinking water, and exercising a lot will help…but even then it isn’t guaranteed you will pass.

The only way to know for sure that you will pass is to detoxify properly. If you want to take the slow, steady approach to cleanse your system, the 2 step marijuana detox is a great solution. It thoroughly cleanses your system throughout 25 days and completely prepares you for your test.

If you don’t have a month but have at least seven days before you will need to take your drug test, this 7-day cleansing program is highly recommended. As you follow the simple regimen for the seven days, your system is stripped away of impurities, allowing you to pass your test.

If you don’t have time to detoxify properly and you need something to cleanse your system as soon as possible, the Fast THC Detox Kit is said to be the most powerful detox on the market and is preferred because the ingredients are all-natural. With a 99.99% success rate, it is by far the best solution for a short-notice drug test.
