How long does marijuana stay in your system?
Single, acute use: urine test
For single use, you’re probably okay in just a few days according to this study from the Journal of Analytical Toxicology:
“Monitoring acute marijuana usage with a commercial cannabinoid immunoassay that has a 50-ng/mL cutoff concentration provides only a narrow window of detection of 1-2 days.”
That means if you recently just used a small amount, it will likely be undetectable with common urine tests in just about 3 days. But the smart thing to do to be sure is to go to the local pharmacy and get a THC test off the shelf. It will be the same one they will use at the job interview, probation, or whatever else have you getting tested for the presence of marijuana in your urine. Additionally, if you want to further expedite the process, consider using a reputable detox product like Toxin Rid to help flush out any remaining traces of THC.

Moderate use: Urine tests
If you’re a moderate user and you are having a urine test which is the most common test, you’re looking at two weeks of abstinence for the THC to leave your system. THC mostly hides out in fat cells, then enters the bloodstream, and slowly leaves the body through the urine. What is it doing in those fat cells? Hopefully, it’s having a mild but helpful anti-inflammatory effect even when you’re not smoking. This may be the reason why children with seizures get protection without having to smoke the stuff all day. It stays in the fat cells and is time released into the bloodstream providing marijuana-deextended protection.
The chart above breaks it down. So check yourself before you wreck yourself. Go get the test from the pharmacy, and make sure you’re clean before you go to that important meeting with the greedy pee-pee thieves. What do you imagine they do with all that urine they took?

How to detox from weed: Best marijuana detox methods
- The best way to detox your body from THC is abstinence. Just wait it out. It’s all about timing. Review the charts above and see which data apply to your case, then just wait it out. Before your court-appointed test, use a store-bought test to make sure you’re clean and you’re literally golden. Clean, golden urine with no drug metabolites in it.
- The second best way to detox your body from THC is detox drinks and detox pills.
Clean your system for drug tests with Detox Pills
If you don’t want to do it homemade and don’t want to buy the drinks, you can get detox pills from the same companies with the same formulas used in their detox drinks, just in pill form. Let’s have a look:
Toxin Rid, 10-day detox
Toxin Rid is a very popular product. It actually has ingredients different from the other detox products. Let’s have a look.
There is one day, 3-day, 5-day, and the most effective 10-day THC detox kits.
Toxin Rid consists of Pre-rid capsules containing electrolytes, minerals, alfalfa leaf extract, and kelp. It does not contain creatine which is not a good sign for detox pills. Creatine must be consumed 2 hours prior to your urine test. How it works is unknown but people have reported successes and failures online.
The liquid detox contains minerals like lithium and boron. The last ingredient is psyllium husk fiber, known to clear out the digestive tract.
Mega Clean + PreCleanse Pills
Stinger Detox 7-day capsules
These capsules have most of our ingredients as you can see in the ingredients list. It lacks the vitamins so get a B-vitamin complex pill to add to the mix. Take as directed on the bottle. Too many b-vitamins will cause nausea, don’t overdo it.
Detoxify: Instant Clean Pills
This product has everything needed, b-vitamins, creatine, diuretics, and even niacin, and zinc. Zinc helps decrease the tendency of drug tests for cocaine and methamphetamine to come out positive, which is helpful for those wanting to keep that medical information private. That doesn’t mean taking a lot of zinc, as that will cause nausea and likely vomiting. Just stick with the formula and the instructions on the package and you are golden.
Rescue Detox Ice Caps
This is a series of 12 pills. Follow the instructions precisely.
Weed Detox Drinks
Why detox drinks instead of pills? Dosing is easier and as long as you just get a good standard drink, with no fancy herbs you have never heard of and don’t know if you’re allergic to, you’ll be good to go. It has been tested anecdotally and scientifically. Journalists at Vice News did the tests themselves and documented that these drinks really did work after they smoked weed close to the test and a few days ahead.
They tested these popular weed detox drinks:
- Detoxxify Mega Clean / Xxtraclean
- Stinger Detox
- Rescue Detox
These tests were doneby journalists, not scientists but we will look later at what scientists have said about detox drinks.
|Detox Drink||Xxtraclean / Mega Clean by Detoxxify||Stinger Detox||Rescue Detox|
In their anecdotal study, they made sure the regular weed smoker tested positive before drinking the detox drinks. Then they followed the instructions to a T (this is very very important) and then she tested negative, all documented on camera and online. Follow the instructions, and do not stray even one bit from them because there’s only about a 5-hour window where you will be testing clean. Each detox drink passed. Does that mean going out and buying any detox drink? No. Get the ones that you know passed, they are available online, at some head shops, and some gas stations. Stinger Detox got the best review from the journalists at Vice because it tasted the best and they didn’t have to drink as much fluid as the others.
Mega Clean by Detoxify, Number 1 Choice A +
The most standard detox drink is Mega Clean by Detoxify. It is possibly also the most popular. If you want to pass no questions asked, get this drink. It is available online from stores like Walmart and Amazon. Though it was not included in the tests done by the journalists, it actually has the same ingredients as XXtra Clean by Detoxify, it’s just the version for a person of lighter or normal weight. It has creatine, b-vitamins, and diuretic herbs, that’s all you need. It also has your electrolytes and even zinc, known to produce the results you want for your test.
It’s important to choose a drink according to your weight because if you choose a drink meant for a heavier person, it could have too much water for you and be somewhat dilute. This will not disqualify your sample but might make the tester want to test you again due to faint lines.
It’s easy to use. Shake the bottle first. Drink the contents, 16 oz. Now refill the bottle with water and after 15 minutes, drink the water down. Afterward, you want to sip water slowly and pee 3 to 4 times before your test. When you refill the bottle and wait for your test, you can drink Gatorade or just put a pinch of salt and baking soda in the 16-ounce bottle with water and a bit of sugar to taste, just so your electrolytes remain normal and your urine is not diluted.
Can detox pills flush marijuana out of your system? Well, they can work. They are essentially the same ingredients as the detox drink, but you add the water yourself. The ingredients are usually creatine, b-vitamins, electrolytes (salts), and a diuretic like green tea or cranberry extract.
Mega Clean + PreCleanse Pills
How do detox drinks and pills get THC out of your body:
Dilution is how these weed detox drinks work and you can use home remedies to do dilution.
Dilution works by putting excess water in your urine, then replacing the creatine and vitamins (they give your pee a yellow or even green color) that drug testers will be looking for. While it’s easy to do with a detox drink such as the ones listed above, it can also be done at home.
What do you need for your home remedy THC cleanse?
You need 2 to 5 grams of creatine for your homemade detox drink. What can you substitute? One large rare steak may have enough creatine to do the job. The tester will measure the metabolite of creatine called creatinine to make sure you haven’t diluted your urine, which you have, but you added back extra amounts of creatine to cover up the dilution.
if you’ve ever taken B-vitamins because they told you you need them for energy, you noticed they made your pee either darker yellow or yellow-green. Yes, that’s what they do and testers are going to be looking at the color of your urine to determine if it has been diluted. Clear urine isn’t a sure sign of dilution, but taken with other factors, your sample could be disqualified as dilute if there is not enough color to it. B-vitamins will add the color and smell you need. Some testers will smell the urine if it is suspect.
Your homemade detox drink needs to be 20 oz to 32 oz, taken 2 hours before your drug test, then sip slowly on a second bottle just to keep the pee coming while you wait to take the test. You want to make two bottles. Electrolytes are just a quarter teaspoon of lite salt, a quarter teaspoon of baking soda, and about 4 teaspoons of sugar. This is gonna get your specific gravity right where it needs to be.
Diuretics are what make you produce excess urine. The most common ones are green tea, coffee, and cranberry juice. However, Wiley detox companies use herbal diuretics. Get the ones we are visiting here, stay on the safe side.
You can buy pre-made urine that will pass a drug test. The most popular and successful product is Quick Fix.
|Synthetic Urine comparisons||Tesclar Powdered Human Urine||The Urinator||Quick Fix Urine|
|Did users pass or fail?||Pass||Pass||Pass|
Each of the top products appears to pass standard tests. Price and convenience are the differentiating factors. Take your pick and good luck keeping your medical and bodily fluids private matters.
TestClear Powdered Human Urine, A+
You should get this product directly from their site to avoid copycat products. That means you may need to plan ahead or if in a hurry have it overnight shipped. You need to mix it with water and strap it to the heating pad for 45 minutes so that it reaches the proper temperature. Let’s see what reviewers are saying about it.
This user passed Qwest Labs testing which is very standard.
We conclude that online reviews for this product are good.
Powdered Human Urine
The Urinator is one of the most fancy synthetic urine systems, they obviously take their craft very seriously.
It is the only kit that is digitally temperature controlled so you can’t miss getting the temperature right (urine has to be body temperature when the sample is collected). You will have to pay up for this kind of peace of mind though, it may be the most expensive of the top products.
Reddit Review, “passed two observed tests…”
Quick Fix Urine: Grade, A
Quick Fix is by far the most popular, and as of today, it is still passing drug tests if the instructions are followed to a T. You also need to buy several kits and practice at home before you show up to the test. You should practice strapping up and putting the urine into your cup for an unobserved test. If you have an observed test, you may need to get fancy gear like a Whizzinator.
Reddit review, “used it in the past with no issues…”
This user used Quick Fix several times and passed. This is the typical story. It usually passes unless the tester uses more expensive, sophisticated testing which is rarely done except maybe to test for doping in Olympic sporting events. For employment and even some court-ordered testing, you will tend to get standard tests. They have to test lots of people, they don’t want to waste money on expensive tests.
We did however find one comment from 4 years ago of a user claiming to have failed with Quick Fix, this is a rarity.
The danger of these reviews of course is that a commercial competitor will hire someone to go online and claim the product failed so that they can try to sell a competing product. This comment however does have the ring of honesty so we will take him at his word. Also, he didn’t technically fail, he has to retake the test. This could mean he did something wrong like added water or urine to the sample such that it came out dilute. Also, sometimes if it doesn’t smell like urine, they will make you retake the test. But the fact that they let him retake it means the sample was not identified as synthetic otherwise he would have been disqualified.
Powdered Human Urine
The fastest way to clean out your system for a drug test of your Hair
Hair tests can reveal drug history going back 90 days. They take the first 1.5 inches of hair, which grows approximately .5 inches per month, and they test a 3-month span. Hair drug tests are some of the hardest to beat. Drug metabolites are routinely deposited into the hair and remain there indefinitely. However, there are scientifically proven ways to get pot out, an actual detoxing of your hair.
- The Macujo Method
- The Jerry G Method, which is bleaching and dyeing
- Perming and other cosmetic hair treatments
There are basically two main pot detox cleansing shampoos used in these methods:
Ultra Clean by Zydot and Old Style Aloe Toxin Rid. You probably want two bottles of both but don’t pay outrageous prices.
The Old Style Aloe Toxin Rid
Basically, scientifically, anything that severely damages and flushes the hair will tend to cause drug metabolites to come out. It is exactly like washing clothes and for that reason, detergents are used in the Macujo method. We will describe them here briefly.
The Macujo Method for Hair THC Cleanse
Lost in the ether of the internet is the Macujo Method. There was a story behind it at first on the message boards but that cannot today be dredged up. Who knows why we call it the Macujo method? It is a method of damaging your hair with acids, bases, detergents, and proteases to get the drugs out. People swear by it and theoretically, it should work since cosmetic hair treatments have been scientifically proven to work.
A study in the International Journal of Legal Medicine entitled “Influence of the cosmetic treatment of hair on drug testing” found significant reductions in all drug metabolites from the hair after cosmetic treatments. Bleaching and dyeing and strong bases were used in the studies. Baking soda is a strong base used in the Macujo Method.
“Influence of the cosmetic treatment of hair on drug testing – PubMed.” https://pubmed.ncbi.nlm.nih.gov/9228567/. Accessed 28 Aug. 2021.
The researchers found that there were differences in the realm of 40 percent to 60 percent for cocaine, morphine, and THC. Bleaching worked better than dyeing but you can do both, and the more damage to the hair, the more drug metabolites were gone.
The Macujo method uses common acids, bases, proteases, detergents, and other chemicals to try to damage the hair follicle and get out the drug metabolites. Of course, the danger is that you could get chemical burns on your head. We are not telling you to do this, we are describing what people have done and the results they claim to have gotten. Here are the ingredients you need for the Macujo Method:
- Aloe Toxin Rid shampoo
- White vinegar
- Warm water
- Ultra Clean by Zydot shampoo
- Shower caps
- Pink Clean and Clear acne wash
- Pack of liquid Tide detergent
- Disposable Gloves
- Rinse your hair well. They will be testing the first 1.5 inches from your scalp, so, your roots. You wanna wash the rest of your hair just so that they don’t contaminate your roots which are gonna be tested.
- Now work in your white vinegar. I’m no chemist but I think it’s safe to say vinegar is acidic. Acetic acid is reactive.
- Now work in the Pink Clean and Clear while the vinegar is still in. Then slap on the shower cap and wait 30 minutes. If as a teenager you had the misfortune to run into this stuff, you know it’s salicylic acid and will react to skin a bit so use it at your own risk.
- After 30 minutes, rinse it out. If you didn’t get any feeling of chemical burn or allergic reaction, you’re good to go. And the more fried your hair is, the better according to our scientific study we just consulted.
- Now use your Aloe Toxin Rid Shampoo. This shampoo has become so legendary online for beating drug tests. Rinse.
- Take a few drops of Tide detergent, and shampoo your roots with it. Tide has protease that breaks down proteins to get into the hair shaft and release the toxins hiding in there, trying to mess up your job interview.
- Use Zydot Ultra Clean Shampoo. It is clinically proven to remove some drug metabolites. One wash with Ultra Clean: a slight decrease in drug concentrations could mostly be observed e.g. cocaine (n = 10) -5%, 6-MAM (n = 12) -9%, morphine (n = 12) -26%, THC (n = 4) -36%.’ That means just one wash with this shampoo reduced drug metabolites in the study. That suggests as part of a detox method with several washes, you could certainly get enough drugs out to test clean.
- Do this process 3 times on the day before the test, and once on the day of the test. If you put in this much work and dedication, you deserve that job.
Aloe Toxin Rid Shampoo + Zydot Ultra Clean
Zydot Ultra Clean Shampoo
Weed Cleanse: The Jerry G Method
- Two bleach and dye kits of your natural hair color.
- Box of baking soda
- Toxin Rid shampoo
- Two bottles of Ultra Clean Shampoo by Zydot
The Jerry G Method is basically bleaching and dyeing ten days apart. We have already noted scientifically that bleaching and dyeing is effective to the point of creating false negative results which is what you want, negative for drugs of abuse.
Step 1. Stop using the drugs that you have been using as soon as you know you have a drug test because you could directly contaminate your hair with drugs or it could come out in your sweat and leech into your hair. If you have ten days of abstinence, that would be great but you can try this however many days you have. You just have to bleach and dye twice.
Step 2. Ten days before your test, bleach and dye your hair, make sure it’s your normal hair color and contains ammonia.
Step 3. On the day before your test, bleach and dye your hair again.
Step 4. Old Style Aloe Toxin Rid Shampoo if you can get it for a decent price, otherwise use Zydot Ultra Clean. Make sure you have enough for another wash on the day of the test.
Step 5. On the day of the test, put a baking soda paste in your hair. You may want to leave it in say 15 minutes. Just baking soda and water, down to your roots. It’s a very alkaline or strong base.
Step 6. Shampoo with Toxin Rid.
Step 7. Shampoo with Ultra Clean by Zydot.
The fastest way to clean out your system for a drug test of your Saliva

What do scientists say about detox drinks and other detox products?
Dilution aka cannabis detox drinks and detox pills works
This 1998 study in the Journal of Analytical Toxicology concluded: “Excess fluid ingestion causes false-negative marijuana and cocaine urine test results.” In other words, herbal detox products beat a urine drug test. Dilution works if creatine, b-vitamins, and electrolytes are ingested.
This 2001 study found that an adulterant called Stealth added to the urine sample produced a false negative result.
“Effects of Stealth adulterant on immunoassay testing for drugs of abuse” showed the addition of this product to the urine sample (do not ingest), beat the drug test. It’s not clear if this product is still produced but we will look at similar products presently.
Synthetic urine worked
This study in Drug Testing and Analysis showed that synthetic urine such as Testclear Powdered Human Urine passed the drug test, was accepted as genuine human urine, and did not show up as adulterated or diluted. In other words, it beat the drug test. There was in the study another more sophisticated test called UrineCheck that could detect synthetic urine, however, these are not usually used in routine urine screening. Anyway, you can just buy real Powdered Human Urine. The study is called, “Can synthetic urine replace authentic urine to “Beat” workplace drug testing?” The abstract states: “All SU products screened negative in the drug immunoassay and additionally passed the specimen validity testing (SVT) as authentic urine.” That means it beat the tests. Only the most sophisticated test could detect it and this test is not routinely used. The brand of synthetic urine most commonly used is called Powdered Human Urine.
Powdered Human Urine
Avoid losing weight before your test
Also, there is one thing to avoid right before your urine test and that is weight loss. Weight loss will cause fat cells to release stored THC into your bloodstream and then into your urine. Scientists have called this intoxication because even without having smoked you now have THC spilling out into your bloodstream due to weight loss. So people who tell you to exercise and sweat it out or abstain from eating don’t know what they are talking about. If you start to lose weight before your drug test, you will cause THC to flood your bloodstream and your urine and you will get a positive result even if you had tested clean earlier before you started burning fat.
Frequently Asked Questions
Q: Can lab tests detect THC Detox Products?
A: Detox products are generally all-natural ingredients that could be in the diet through regular ingestion. Detox drinks and pills cannot be detected. Adulterants added to a sample may be detected, depending on what the adulterant is. According to a study in The American Journal of Clinical Pathologies on adulterants: “Most of these adulterants except eyedrops can be detected by routine specimen integrity tests (creatinine, pH, temperature, and specific gravity); however, certain adulterants such as Klear, Whizzies, Urine Luck, and Stealth cannot.” They identified 4 adulterant products that work and cannot be detected.
Q: Do THC Detox Kits work for hair tests?
A: If you have a hair test, a detox drink will not help you. You would want to use a hair detox method such as the two described previously.
Q: What to do if I need to cleanse really fast?
A: The quickest thing to do is get a good detox drink. If you don’t have one available, eat a large steak and drink 32 ounces of green tea exactly two hours before your drug test and have extra tea to sip on. If you have creatine monohydrate, use two to five grams in your tea or take it as capsules. Don’t worry if you don’t have that, the steak has creatine in it but you want it in your blood and urine by the time you are taking the test so give it a boost with two to five grams of creatine powder if you have it. A second option is to use substituted urine for your cannabis test.
It is completely proven possible to test a false negative on marijuana or other drug test using detox products where they are legal. You have to check your local laws to find out if they are legal. We do not advocate the use of any such products in places where they are not legal. We are describing the products which are available and how people are using them to keep their bodily and medical parameters confidential, between you and your doctor.
Urine drug tests are routinely beaten by the method called dilution. It can be done fully naturally simply by eating a large steak and drinking 32 ounces of green tea two hours before your test. This cannot be made illegal nor can it be detected since it’s merely timing your meal in an advantageous way.
Detox companies discovered this and produced drinks that must contain: creatine, b-vitamins, an herbal diuretic, and electrolytes (salts). These drinks will work, stick with the ones which have been demonstrated to work.
Hair detox is fairly simple, bleach and dye are basically what is proven to get drug metabolites out of the hair. Perming also has some effect if one was inclined to get hair permed. Lastly for saliva tests, just swish peroxide through your mouth. It is cheap, available, and highly effective. Good day, and happy toking! Keep your medical data confidential.
