How to Pass a Urine Drug Test for weed in 24 Hours.

Perhaps you are looking for a job. Maybe you already have a job. Or maybe your parents have decided to spring an unannounced drug test on you. Regardless of the reasons behind it, if you have a urine drug test in 24 hours, you need to act fast if you want to pass it.

Fooling urine drug tests isn't easy, but it's not impossible either. As long as you have the right tools at your disposal, you can pass that test.

Naturally your best defense during a drug test is to be clean. But, this is difficult since urine drug tests can detect use of marijuana up to five days after occasional use and up to three weeks for regular users. Urine tests detect non-active metabolites and while this is not the psychoactive ingredient of marijuana (which is THC), any trace of these metabolites can lead to a positive drug test.

Marijuana in the Body

Most people consume marijuana by smoking it. Smoked marijuana moves down the windpipe into the lungs, where it then moves through the lung's air sacks and enters the bloodstream. THC, the most powerful chemical in marijuana, is absorbed by fat cells and tissue as it moves throughout the bloodstream.

Depending on the person, it can take one week to one month for all the chemical traces of just one marijuana cigarette to leave the body. How long the THC stays in your body also depends on your overall health and the potency of the drugs. THC in your system soon is naturally broken down into metabolites, although it can take a long time.

As more marijuana is smoked, the THC builds up in the fat cells and takes even longer to fully leave the body; it can take chronic, repetitive users up to three months to fully get the THC out of their bodies. That can be bad news when most drug tests are ordered to take place within a few days, not a few months.

Marijuana in the Urine

THC residue gradually breaks down from your blood stream into metabolites as you drink fluids, exercise, and just go through normal life. THC exits the body through the feces and urine, which is why urine samples are the drug test of choice when testing for marijuana and other similar drugs.

How Drug Tests Work

Urine tests account for more than 90% of all drug tests in the U.S. because they tend to be the most effective and some of the simplest to administer. Urine tests measure the amount metabolites (or processed THC) in your system.

The typical cutoff for a negative drug test is 50 ng/mL, which is the level an occasional marijuana user can naturally reach within 4-7 days of taking drugs. Most samples are tested at least twice using different processes. If the sample is positive or if there are difficulties with the reading, additional screenings or a new sample may be required.

At-Home Passing Methods

If learning about urine samples is causing you stress, don't worry. You're in luck there are a number of methods that can help you pass a urine drug test. Although none of these methods are foolproof and their success depends largely on your size, overall health, and drug consumption levels, you can try a few to see what works best with your system.


Known as flushing, this is definitely the least expensive and one of the easiest methods to pass a urine drug test. Water is a natural start to the detoxification process and dilutes the amount of drug residue in your urine sample. It is also untraceable in a urine test. Starting two days or more before your test, drink at least 64 ounces of water a day.

For best results, sip the water instead of chugging it all in one sitting. And while it may be tempting to drink even more water to make sure your system is completely detoxed, drinking too much water can hurt your internal organs and your test results. If your urine is determined too diluted to test, you may be called in for another drug test.


Another natural way to detox your body is through exercise. As you exercise, your increased metabolism pushes the detoxification process along and breaks down the fat cells where THC is stored. Sweating rids your body of all sorts of toxins and can help get rid of drug residue faster than just peeing it out.

Be careful not to overdue it by exercising on the day of your test; for best results, exercise regularly up until the day of the test, but not on the actual day. Exercising actually detoxes your body, so it isn't traceable in a urine test.


Niacin, or vitamin B3, is sold as a weight-loss pill and is available over the counter at many supplement stores. Simply take two pills a day starting two days before your test. Niacin enlarges blood vessels and makes the blood stream more water soluble, which helps process and detox the body faster. However, it can occasionally be detected in test results, isn't always effective, and can have serious side effects, including vomiting, fainting, and liver damage.

Baking Soda

With this method, mix three to five tablespoons with a large glass of water and drink two to three hours before taking your test. Baking soda is incredibly inexpensive and works to mask the pH imbalances in urine that are caused by THC output. However, very unusual pH levels can be grounds for an additional test. Baking soda can cause very unpleasant side effects and isn't reliably effective.

Using Someone Else's Urine

This might be the simplest solution in theory, but putting into practice is another story. If your test is taken at home, you can simply recruit a drug-free friend to submit a sample for you. If the test is taken at your office or in a laboratory, you'll have to sneak in a small sample of someone else's urine.

Urine samples can come from family and friends and can even be purchased on the Internet. Although you have a higher risk of getting caught, this method can regularly beat the lab results if you can effectively sneak in the urine.


Drinking alcohol is a way to speed up the detoxification process by encouraging more water to leave your body. Drink one to two beers or glasses of wine in the few days leading up to your drug test. The test will likely recognize the alcohol in your system, so this method is only effective on tests that don't measure alcohol levels. It will also only help with THC that is in your bloodstream, not the THC that has already accumulated in your fat cells and tissues.


Because vinegar is an acid, it can help break down the digestive system and rid your body of toxins and chemicals like THC. Most people combine vinegar with a small amount of lemon juice or cayenne pepper to mask the taste. Take a few servings of vinegar in the two days leading up to your test. Vinegar can change the pH levels of your urine and may necessitate another test. It can also be very harmful to your system when consumed in large amounts.


Body building supplement creatine is available over the counter at most supplement stores. It works to speed up the flushing process and to cover the fact that your urine may be diluted from drinking so much water. Dosage amounts depend on your size, but most people take 100mg a day for the two to three days leading up to the test. It is debatably effective and in most cases can't be noticed in the urine sample.

Cranberry Juice

Cranberry contains ingredients that naturally flush your body of excess water and sodium. Cranberry is a natural diuretic. Although this method is not entirely effective on its own, it can be useful to combine with other methods to push the detox process along. Drink at least two large glasses of cranberry juice for the two to three days before the test. It won't be noticeable in the test results.


Take two to four aspirin four to six hours before your test. Aspirin absorbs chemicals as they leave your body, which allows it to absorb many of the metabolites before they make it to your urine sample. You might end up a little lightheaded if you take a larger dosage, but it should help push your test results in the right direction. Aspirin can't be detected in the sample results.


Bleach can be added to the urine sample to remove metabolites from the urine. The best results come from using bleach crystals and grinding them into the sample, but a few drops of liquid bleach can also work. However, bleach tends to be very noticeable in test results because it can leave behind a film or scent and also changes the pH levels.

Pickle Juice

Some people believe that if you drink large amounts of pickle juice, the acid will kill the THC cells in your urine sample. This would require incredibly large amounts of pickle juice and is hardly ever effective. Most people who try the pickle juice method end up combining a few other methods to increase their chances of passing the test.


Sitting in a sauna raises your body temperature, which causes you to sweat and release toxins and chemicals from your body. This method is best used in combination with other methods, such as exercising and drinking water. To be most effective, sit in the hot sauna for 10-minute increments and take a short break with lots of water in between. Do this for a few days before the test. Because this method doesn't add anything to your blood stream or urine, it is undetectable in test results.

Eye Drops

Similar to the bleach method, adding a few eye drops or saline solution to a urine sample is believed to cancel out many of the metabolites. To use this method, urinate as usual and then add a few drops and mix in into the sample. This method isn't always effective. It can occasionally be detected by the lab, but not at the same amount as using the bleach alternative.

    Bought this for my husband to pass a test for a job. He is a big guy over 300 lbs and daily smoker. He quit 7 days prior to test day, followed the directions on bottle and also took the chewables and passes the test. Prior to this drink I purchased a different kind a month before that had him come up positive. This products really does work.

    I see there is only 29 reviews, so for those people out there that aren't sure about this product this definitely is a great product. I am an average person, 5'9 135lbs and I smoke about every other day almost everyday for the past year. I was offered a new job at a fortune 50 company which is HUGE for me. The first thing I was told was that I needed to take a pee test, i was prepared for this but I was stillI scared because I stopped smoking only 2 weeks before and the test was scheduled in two days. I quickly researched some detox kits but I wasn't sure if they would work but I took the chance anyways and bought the most reasonable one I could find. 2 hours before the test I followed every instruction to the T, and after a nerve wrecking weekend I got the call telling me I passed the test. Hopefully this review is helpful to my fellows potheads out there, I recommend this product to anyone.

    So this is the first review I have ever wrote and I kinda feel like I had too because this stuff actually works. I got the job on a Thursday and had till Monday to do a drug screen before it's official. So obviously me being a smoker I smoked Wednesday the night before, so I drank about a gallon of water from Thursday till Monday and about 2 gallons of green tea lol I felt like a peed 3 to 4 times an hour. So on the day of my drug screen (Monday) I follwed the instructions word for word. After all that I still wasnt confident that this would work but i had no other choice I just had to wait and see. Two days passed by and I haven't heard from my job. I was getting ready to rate this a one and say this was fake, but in the third day I got the call that I was good to go and start training as soon as I can. This really works. I have 100% confidence now In this detox and I will definitely buy this again the next time I have a drug test and write another review about how that went. If I remember that is lmao ;)
