Below we will describe the guaranteed ways to pass a drug test even if you have only 24 hours.
Check the following guides if you need to pass a urine, hair, or mouth swab drug test.
How to Pass a Urine Drug Test
Flushing – when you temporarily flush marijuana metabolites out of your bladder.
These methods use large amounts of water and diuretics to make you urinate frequently and thus flush the THC metabolites from the bladder.
The concentration of THC metabolites will reduce temporarily.
You will need to take vitamins and electrolytes to keep the color, creatinine levels, and specific gravity within the normal range.
Best for: People who don’t want to stop smoking for a long time, who don’t have much time before the drug test, who have to pass a supervised drug test.
You will need
Electrolyte powder or drink: This supplement consists of sodium and magnesium. It keeps your urine’s specific gravity level in check.
Creatine ethyl ester supplement: This helps raise the creatinine levels above the cutoff mark, especially if you are struggling with lower levels of this urine component.
Vitamin B supplement: This gives urine its natural color.
Aspirin: Its metabolites cause false-negative results in the immunoassay drug tests (link here).
- Take the 10 grams of creatine ethyl supplement 3 hours before the test.
- Take 200 milligrams of vitamin B 3 hours before the test.
- Drink 1000 milliliters of electrolyte solution every hour for three hours before the test.
- Take two aspirin tablets four to six hours before the test.
- Take a home urine test before you go to the test center.
- Drink 20 ounces of water 2 hours before the test.
- Wait 20 minutes and then drink the entire bottle of QCarbo Plus with all 5 Super Boost Tabs.
- Refill the empty QCarbo Plus bottle with water, wait 20 more minutes, and drink again.
- Urinate two times and then use the included self-test kit. If results are desired, submit your test sample as soon as possible if results fail to proceed to step 5.
- Chew the QClean tablet with 32 ounces of water. Wait an additional hour, and be sure to urinate several times before going to your test.
Substituting urine sample – when you submit a clean urine sample instead of yours.
Substituting the sample with the synthetic urine or someone’s else urine, you will have a sample that is 100% clean from any THC metabolites.
This method requires additional devices like hand warmers to keep the sample temperature normal. And, probably, a whizzinator.
Also, this method is not legal.
Best for: People who have no other options for some reason. This method is not legal, and we don’t recommend it.
Synthetic urine comes as a powder that you will have to turn into a mixture; here are the instructions.
- Mix the powder with water.
- Use the equipment provided to get it to the right temperature.
- Place it into a heating pad.
- If you need to hide it – do so.
- Bring at least 30ml to the test center.
The biggest challenge is getting it into the test center and into the bathroom, where you will take the test. Here are some suggestions.
- Wear a pocket belt around your waist and slot the container into the pocket.
- Tape the container to the inside of your thigh.
- Women can insert the container into their vaginas.
- Use a fake penis or whizzinator
You need to collect clean urine in a squirty bottle to sound like you are peeing when you are in the toilet.
Since the urine has to be a specific temperature, you can’t do this the night before and carry it to the test center.
Ask your friend to come with you and get them to pee into the bottle just before you go in.
Keep the pee warm enough by resting it on the heating pad.
Put the bottle inside your underpants near your genital region. To use it, follow the same procedure as the synthetic urine.
You can collect and store your urine and use it on the day of the test.
Detoxification – when you permanently remove THC metabolites.
Using this method, you will remove THC from the body and thus reduce the urine’s metabolites’ concentration.
You will be clean permanently until you use marijuana again.
This method requires following the proper diet regimen and exercising regularly for several weeks. Or using additional supplements that will help you to detox.
Best for: People who want to permanently remove THC metabolites from their system and have at least one week before the test.
The following instructions are simplified. You can read the complete guide on natural detoxification here:
Drink at least 2 liters of water. Water works as a natural appetite suppressant, thereby making the body metabolize fat.
Eat leafy greens. Substituting high-calorie ingredients with fruits and vegetables adds volume to your dishes without adding lots of calories.
Lemon juice added to warm water promotes quick weight loss by improving digestion and boosting metabolism.
Say no to junk food and red meat. Junk food is often packed with loads of calories. These excess sugars and fats add to your fat layers, thereby increasing the storage surface for THC.
Eat healthy fiber. Fiber acts as a natural suppressant by reducing appetite. Healthy high-fiber foods include legumes such as black beans and kidney beans, nuts such as peanuts and almonds, bread such as rye and wheat bread, and fruits such as mangoes and pears, apples, and berries.
Exercise. 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.
Adding something to the urine
This method requires you to add adulterants(like zinc bleach, eye drops, vinegar) to the urine sample, so they will interfere with the drug test and produce a false negative.
This method worked 20-30 years ago, but modern drug tests can detect adulterants, and the lab will reject your sample.
Best for: no one. This method is not working anymore.
How the drug test will be conducted
You will have to submit a sample. The lab technician will check your sample for the right temperature and color. After that, he will seal your sample and send it to the lab.
The lab will check it for the specific gravity, creatinine levels. If these parameters are ok, the lab will check the sample for the metabolites’ concentration using an immunoassay drug test.
If it shows positive – the sample will be tested using a confirmatory gas chromatography test that is much more precise.
So you need to pass the immunoassay test to avoid the confirmatory drug test. To do this, you need to lower the concentration of drug metabolites in the urine below the cutoff level.
It’s usually 50ng/ml for THC(marijuana). You also need to have creatinine levels and specific gravity within the normal range.
How can you do that?
How to Pass a Hair Drug Test
In case you have forgotten, a hair follicle drug test involves a few strands of hair being cut from your head and tested for the presence of drugs over 90 days. It is a very accurate test capable of detecting the length of time you have been using a specific drug and when you stopped using it. The hair follicle test can also determine the quantity of the drug taken. This type of drug test is not used often because it is so expensive.
Research has found that the hair follicle test is five to 10 times more effective than the urine drug test. This amounts to approximately 85% of users who failed a hair follicle test passed a urine test. The accuracy of the hair follicle test is why it is the preferred drug test for employers. Marijuana is detectable in the hair for several months.
The most effective way to clear drugs out of your system is to do so naturally. The only downside to this is that it depends on how much time you have. The longer you don’t take any drugs, the better, but the average time is 110 days. After which you will also need to get a haircut.
ZYDOT Ultra Clean Shampoo
Several hair detox products on the market will help you pass a hair drug test. One of the most popular is the Zydot Ultra Clean Shampoo. The manufacturers are so confident about their product that they offer a full money-back guarantee if it doesn’t work. You can use the shampoo to eliminate any drug from your hair follicles. The good news is that you can use it on the morning of your drug test, and it will still do the trick.
The Macujo Method
The Macujo method involves a seven-step cleaning process; unfortunately, you will have to stop smoking for it to work. But once your test results come back negative, you can spark up again. Don’t be put off by how strange this method is. All you need to know is that it works. The majority of people who use this method pass, so give it a go. Here is how to perform the Macujo method:
- Dampen the hair with warm water, make sure that it is not soaking wet.
- Massage Heinz vinegar into the hair and scalp.
- Massage some Clean and Clear into your hair and scalp.
- Put a shower cap over your head and leave the mixture in your hair for half an hour.
- Wash your hair using Nexus Aloe Rid Shampoo.
- Rewash your hair using Tide laundry detergent.
- It is recommended that you repeat this process at least five times for it to work.
How the Test is Conducted
- The test either occurs in a hospital, or administering the test will send the hair to a lab for testing.
- The test is supervised. It is also important to mention that no matter how many times you wash your hair if you use styling products or dye your hair, it will not affect the test’s accuracy.
- The technician will cut between 100 and 120 strands of hair from the crown of your head. To avoid bald patches, they will collect it from different areas on the crown.
- You will not get away with not taking a hair test because you are bald; the hair is taken from other parts of your body.
- Once the hair is collected, it is wrapped in foil and then placed in an envelope and sent to the lab for testing.
- If the results are negative, you will get them back within 24 hours.
- If the results are positive, you will get them back within 72 hours.
- If the test comes back inconclusive, it is retaken.
- The test results are delivered to the organization that requested the test.
A hair follicle test is difficult to manipulate, although not impossible. Since the hair is cut directly from your head, you can’t use someone else’s hair. You are not left alone with the sample, so you can put nothing into changing the results. Either way, there is no scientific evidence to support that this is even possible. What you eat or drink will not change the results.
How to Pass Mouth Swab Drug Test
As mentioned earlier, a mouth swab drug test involves saliva being removed from the mouth and tested for drugs. Employers typically use it because it is quick to administer.
With a mouth swab test, cannabis can be detected for up to 72 hours. Variables such as weight, height, metabolism, and the amount and frequency you smoke will influence these 72 hours. THC is eliminated from saliva in 12 hours with people who only smoke once a month.
- Drink lots of water: This keeps you hydrated and helps the fluids in your mouth to keep moving.
- Eat a high-fat meal: If it is possible to eat a high-fat meal about an hour before your test, this can help reduce the drug metabolites in your saliva. The fat will absorb the metabolites from your bloodstream so that less of them manage to reach your saliva.
- Chew some ice: Some have found it effective to chew an ice block just before the test. The ice will cleanse your mouth and also gets rid of any lingering traces of marijuana that may still be in your saliva. Of course, this is most effective if you have not smoked for at least twenty-four hours before the test.
- Chew some gum or mints: A similar method involves chewing gum or mints, which will dilute your saliva and increase your chances of a negative test result. In general, the idea is to keep your mouth clean by brushing your teeth and chewing gum, mints, or ice.
When it comes to detoxing your mouth before a swab test, the best method is to use mouthwash. There are a variety of effective products available such as the following:
The Ultra Wash Mouthwash can be used similarly, and it is an all-natural product that also tastes good. It works within minutes and remains effective for up to one hour, effectively preventing drug detection. It comes in a very convenient and discreet little bottle, which can be slipped into your pocket or your desk drawer at work. If you have a bottle of Ultra Wash Mouthwash handy, you can always be prepared for any unexpected swab tests.
Get Ultra Wash Toxin-Cleansing Mouthwash
This can be used as a cleansing mouthwash. You would need to rinse your mouth thoroughly for about three minutes with hydrogen peroxide an hour or less before the test. After you have rinsed, do not brush your teeth or drink anything until you have had the swab test.
How the Test is Conducted
- A small instrument such as a cotton swab or a brush is used to wipe the cheek area’s side.
- It is then rubbed onto the gums and left underneath the tongue for a couple of minutes.
- The instrument is then inserted into a test tube containing a clear liquid. If the liquid changes color, you have failed the drug test.
- The test is also administered using an absorbent strip that changes color if drugs are detected in your system.
If you are looking for a cheap way to pass and are ready for some difficulties – use the “dilution + aspirin” method.
If you are sure that you can keep the temperature of the fake urine within the normal range and the test is not observed – use synthetic urine.
If you need the urgent and hassle-free method – use the Fast Marijuana Detox Kit.
If you want to get clean from marijuana permanently, you need the detoxification method.
How to Increase Your Chances of Passing a Urine Drug Test
- Take the test in the afternoon: If you can choose what time you take your test, make sure you take it in the afternoon instead of first thing in the morning. This will ensure that your urine is not as concentrated.
- Use a home testing kit: Home testing kits are relatively accurate. If you take a test before the real thing and pass, you will not be so nervous when it comes to the actual test.
- Keep going to the toilet: You want to dilute your urine as much as possible, but don’t go over the top with this, or it could raise suspicions. Drink a lot of water so that you keep going to the toilet.
- Calm down: Take a few deep breaths before you go into the test center. If you appear nervous, it is going to set alarm bells ringing. The technicians might be all nice and smiley, but they have been trained to look for suspicious behavior.
- Don’t smoke or drink: You don’t want anything to ruin your chances on the day of the test, so no matter how nervous you feel, don’t smoke or drink.
- Don’t take any vitamins or medications: Unless you are on medication prescribed by your doctor. To be on the safe side, take your prescription medication with you to the test center, but don’t let them know unless they ask.
- Avoid toxins: Stay away from anywhere that will expose you to toxins for 48 hours. You don’t want anything to ruin your chances of passing the test.
- Eat a clean diet: One week before your test, refrain from eating junk and greasy foods. Stick to healthy foods such as vegetables, fruit, and whole-wheat products.
- Don’t eat a lot: On the day of the test, have a small meal beforehand.
- Increase your water intake: The longer you can do this, the better, but for at least two days, drink four 16-ounce glasses of water per day. Water helps to detoxify the body, don’t drink it all in one sitting. Sip it throughout the day.
- Speed up your metabolism: You can speed up your metabolism by exercising. A leisurely walk isn’t going to do the trick. You need to get your heart rate going. Start exercising a week before the test and stop a day before.
Home Remedies That Will Not Work
So here are some of the most popular urban legends that will make you fail a drugs test instead of passing it:
It is essential to mention that niacin is so toxic that hundreds of people end up in hospital after taking it in hopes of passing a drug test.
One of the most common theory is that it helps to remove THC from fat cells through vasodilation.
However, there is no scientific evidence to verify this claim.
Certo (Sure-Jell) Fruit Pectin
People believe that Certo, a type of fruit pectin, covers the bladder and stomach lining to prevent THC from being released into the urine.
It gives you a short amount of time to take a test without drugs being detected in your system.
Many users reported the method worked for them, but many people said that it didn’t.
Another problem is that there it is not known how much fiber is present in Certo. This means that there is no way to determine how much you need to take to work.
Cranberry juice makes you pee; it contains pectin, niacin, zinc, and salicylic acid, which help pass drug tests.
May I add that this is true for salicylic acid and not the rest?
One of the problems with this theory we don’t know how much salicylic acid is in cranberry juice, and you will need to consume a specific amount.
But cranberry juice helps with natural detoxification.
Apple cider vinegar
Yes, apple cider vinegar is a natural detoxing agent; but it certainly won’t help you pass when used as a same-day solution.
For the apple cider vinegar method to work, it takes up to 8 weeks to boost fat metabolism and activate the detox process.
So, unless you will stop smoking for eight weeks, this is not a reliable method.
Azo products are used to treat urinary tract infections; they are available in capsule or juice form.
The active ingredient is cranberry, which is one reason people assume it can help them pass the urine drug screening.
There is no scientific evidence to support the claim that Azo products will help you pass.
One of the side effects of taking azo pills is that it turns the urine into a bright orange color.
Since this is not the natural color of urine, and the technicians are aware of this, you will fail the test whether drugs are present in your system or not.
Some believe that baking soda causes the stomach to absorb drug metabolites, which results in vomiting.
This is how the toxins from the drugs are released from the body. It also alters the pH levels of the urine, which will get you an immediate fail anyway.
Meth users have reported that baking soda has helped them to pass a drug test; however, this is because meth is a base, and THC-COOH is acidic.
Since the content of urine is acidic, there are no problems when it comes to eliminating meth. This is one of the many reasons why baking soda will not help cannabis smokers.
Sweating THC out
Since our body stores THC in fat cells, people believe that they can sweat THC out of their system.
The body removes the toxins through sweat; however, there is no scientific evidence to suggest how much THC is eliminated through sweating.
Green tea is a very healthy drink, and research shows that it detoxifies the body. But it does not rid the body of THC.
The belief is that green tea burns fat cells, which stimulate the release of THC through urine.
There is no scientific evidence to support this claim, and marijuana smokers who have tried this method have reported that it does not work.
One of the main ingredients in pickle juice is vinegar; the belief is that due to its acidity, pickle juice neutralizes the THC metabolites, so that drug test doesn’t detect it. And that’s not true.
Although you can use vinegar as help during detoxification, it doesn’t work on the same day.;
Potable Aqua is a water purifying agent. Some people drink water containing potable aqua to clean the urine of THC.
Another method is to add potable aqua to a gallon of water and pour it into your urine sample.
There is no scientific evidence to verify these methods.
Many people have reported that they failed a drug test as a result of using this method.
Goldenseal is a medicinal herb that can help in treating inflammation, respiratory infections, and digestive disorders.
Some believe that Goldenseal prevents THC metabolites’ buildup in the urinary tract passages, eliminating them from the body resulting in negative test results.
If you add a few drops of Visine to your urine sample, it will dilute the drug metabolites and mask THC metabolites to create a false negative.
Although there is some truth to this method, it is not advisable. By the way, it is essential to mention that you should NEVER TAKE EYE DROPS ORALLY!
If you manage to get away with using this method, there is a possibility that it might reduce the drug metabolites concentration to manipulate the test results.
The bottom line is that even if this does work, being able to put anything into your urine sample is virtually impossible.
Some believe that two of the main ingredients in Midol, Acetaminophen and Pyrilamine maleate, assist in ridding the body of THC metabolites and manipulate the drug test equipment.
There is no scientific evidence to support this claim.
The theory says that zinc attaches itself to the THC metabolites, which creates a large molecule that the kidney cannot filter, and so instead, it exits the body when you take a dump.
There is no scientific evidence to suggest that zinc attaches itself to THC metabolites, and even if this were the case, it would still be able to pass through the kidneys.
Another myth concerning zinc is that when taken, it hides the THC metabolites so that the test cannot detect them.
The majority of scientific studies into zinc and drug testing have concluded that zinc does not interact with the metabolites. Still, it can play a role in manipulating the actual test.
Factors That Can Affect Test Results
How often do you use drugs: The more you use drugs, either in amount or frequency, the higher the chances of a positive drug test result.
What drugs are you using: The body breaks down certain drugs faster than others, so the type of drugs you take will influence your test results.
The purity of the drug will also determine whether it is detected or not. Some drugs are cut with other products meaning they are not as strong as others.
Total body fat: No matter how little or often you use it, fat cells store THC. This means that the more fat cells you have, the more likely you will get a positive drug test result.
Health and metabolism: The metabolic process breaks down everything that enters the body. The higher your metabolism, the faster drugs are broken down and eliminated from your system.
This process also depends on gender, genetic makeup, the amount of exercise you do, and age. Evidence also suggests that certain foods can alter metabolism and affect whether drugs are detected or not.
Frequently Asked Questions
Can second-hand smoke show up on a drug test?
A study conducted by the Institute of Legal Medicine in Germany found that after placing non-marijuana and marijuana smokers in a well-ventilated space for three hours, there was THC present in blood and urine samples; however, the levels were not high enough to fail a drug test.
What states require drug testing for welfare?
15 states in America require drug testing for people applying for welfare. These regulations apply specifically to those wanting Temporary Assistance for Needy Families.
The laws in each state are different: Arizona, Florida, Georgia, Michigan, Utah, Wisconsin, West Virginia, Tennessee, Oklahoma, Missouri, Mississippi, North Carolina, Alabama, Arkansas, Kansas.
What is a false positive drug test?
Although a rare occurrence, drug tests can produce inaccurate results where prescription or illegal drugs are detected in a urine or blood sample despite the individual has not taken any drugs.
How accurate are home drug tests?
Home drug tests are fairly accurate, and drugs will show up in results if you have been taking them. If a home test is positive, you are almost certain to get a positive result for a lab test. However, external factors can affect the accuracy of a home drug test. These include:
- Urine temperature
- Contaminants in the sample
- Whether you are on any other medication
What happens if you fail a drug test?
The consequences of a failed drug test will depend on why the test was taken. If you are on probation or parole, and abstaining from drugs is one of the conditions, a failed test could send you back to jail.
If it was for employment purposes, you might get a chance to have a second test after a certain period.
There is also the possibility that you will have to take regular drug tests to remain employed.
Does a failed drug test go on your record?
If you fail a drug test when you are on parole or probation, the test results will be added to your criminal record.
However, if you fail a drug test at work, the results are kept confidential even when your new employer is requesting a reference from your old employer, they can not divulge such information.
How long do drug test results take?
If your drug test results are negative, expect them back within 24-48 hours. Positive results take slightly longer, and you should add three days or more to 24-48 hours. You will know if you have failed a drug test if you don’t get the results back within 48 hours.
Do they check for nicotine/steroids/HIV?
No, employers use drug tests to determine whether their employees are using illegal drugs.
Can you fail a drug test by touching or smelling weed?
Since smelling or touching weed does not involve inhaling it, you will not fail a drug test.
Can a drug test detect synthetic weed?
The answer to this question is yes and no because sometimes they show up and sometimes don’t.
The main reason for this is that there are over 140 different types of synthetic weed, making it difficult to determine which one will be detected.
How Accurate Are Home Drug Tests Compared To Lab Tests?
The home drug tests are as accurate as the laboratory drug screens are(emit drug tests). Confirmatory GC MS drug tests are more accurate than home drug tests.
How Long Do Drug Test Results Take?
Negative results are usually received within 24 hours; however, a positive screen will require further testing that may take a few days up to one week.
Will One Hit Fail A Urine Test?
No. One hit of weed is not enough to fail a urine drug test.
How To Pass A Non-DOT Drug Test?
The methods of passing the non-DOT drug tests are the same. Dilution and Aspirin for urine test and Macujo or Jerry J method for a hair drug test
Does Niacin Work For Drug Tests?
No. We busted this myth in another post. Niacin cannot help you to pass, but it can cause damage to your liver. Do not use it.
Does Fake Urine Work?
Yes, using fake urine can help you pass a drug test, but this is not legal. Use reliable and legal methods described above.
If You Pass A Home Drug Test Will You Pass A Lab Test?
Sure. However, if you need to pass a confirmatory GC MS, then using a home drug test is not reliable.
How Long For A Skinny Person To Pass A Drug Test?
It depends on the amount of marijuana consumed and the smoking frequency. If you smoke once in a while, you should be clean in a week.
