How Long Does Marijuana Stay in Urine?

How long does marijuana stay in your urine? What about saliva and hair? And how do you pass a marijuana drug test? Here’s a look at what the science says.

marijuana drug testWhen conducting a marijuana drug test, companies often use a urine test. There are several factors that determine how long weed stays in the urine.

Here are a few:

  • THC percentage of the cannabis being consumed
  • The BMI of the person consuming the marijuana
  • The rate of consumption (how often they smoke)
  • How fast the consumer’s metabolism works


With this in mind; here’s what the research shows in regards to how long marijuana stays in your urine:

  • If you consume marijuana once, it should be out of your system in 5 to 7 days.
  • Cannabis will stay in the system for 10 – 20 days for those who consume it a couple or a few times a week.
  • For heavy consumers (5 or more times a week) it can stay in the system for 30 to 65 days.


Saliva and Hair Tests:

Two other popular methods are saliva tests and hair tests. Saliva tests are the least invasive; if you’re a daily smoker, studies have shown that in most instances it should be completely out of the system after 72 hours. If you smoked cannabis only once, it will likely be out of your system in 24-48 hours.

air tests, on the other hand, are far more invasive. Cannabis can be found in the hair up to a year after last consumption. Many companies have stopped using hair drug tests, however. Part of this is due to research released last year which found that hair tests can have false-positives for marijuana “because of transfer through cannabis consumers, via their hands, their sebum/sweat, or cannabis smoke.”




How do I Pass a Marijuana Drug Test?

The safest and most effective way to pass a urine drug test for marijuana is to abstain from consuming it; if you’re a heavy smoker, this may mean abstaining for two months or more.

Another option is to do a Google search for “marijuana detox” or “drug testing detox”. Here you will find a plethora of options for cleaning your system and clearing your urine; we highly recommend reading reviews first, however, as some work much better than others.

Another option is to dilute the marijuana in your urine by drinking massive amounts of liquid. This may work to shorten the amount of time the THC is in your system. However, it’s not magic and won’t allow you to pass a test if you’ve smoked recently.

If taking a marijuana saliva test, abstaining for a few days should be enough for even heavy users. If you can only abstain for a day or two prior to the test; suck on the sourest candy you can find for a couple hours beforehand.

If taking a marijuana hair test, there really isn’t much you can do, unfortunately.



THC-COOH is the main secondary metabolite of tetrahydrocannabinol (THC) which is formed in the body after cannabis is consumed. Most drug tests don’t test for THC; they test for THC-COOH.

The reason this is an issue is because THC-COOH can stay in the body for longer than THC.

What about CBD Consumption?

Standard drug testing tests for THC metabolites, not CBD. This means that consuming CBD will not make you fail a drug test; that is so long as it has had all of its THC removed; or if it’s hemp derived (meaning it will already have virtually no THC).

    I smoke a at least 8 bowls a day and I’m 300 pounds. I’m having gastric bypass and they said I have to test neg for THC and nicotine before they preform the surgery. I just quit and don’t know how long I should wait before I take the test (the test is sensitive enough to pick up second hand smoke from both).

    Please tell me how my wife could fail a urine test she just had today at her job when she last smoked over 7 wks ago? Also, she only smoked a few times over a 5 day stretch. Each time was maybe one or two hits before bed time. Thats it. Shes been clean for almost 2 months. Shes about 5’4, 170-175lbs. Lastly after her test, she went to walgreens and got Quickscreen at home drug test, the results are negative. Is this possible???

    Hello I need help!!!! I dont smoke at all. I weigh 230lb so im fat and am 5,4″. I had a piece of my boyfriends cookie saturday a little over two nights ago. It was probably 10-15mg if that Then I got a call from a job and they scheduled me for a drug test ecup non-DOT yesterday within the next 3 days. SO i have till Thursday 2pm to take it. I am detoxing with tea to clean my liver and kidneys and drinking plenty of water. From what I heard the Urin test is 50ng/ml which im think I will pass…its the gc/ms i am worried about because the cut off is 15ng/ms. Can anyone relate to this and pass their test by anychance? Should I be worried?

    I am overweight and also a heavy smoker and when its required for me to pass a drug test I stop for bout 21 days. In between I consume plenty of coffee and water and do weightlifting, cardio, and walking. I pass with ease every time. Some posters are full of shit and say they seen positive results months after quitting.

  2. Hello, I haven’t smoked in 32 days and I run 3 miles a day and consume a lot of liquid. I just took a marijuana strip tst and was unsure if passed or not it said I did but I’m not sure if it is accurate. I weigh 135 lbs. And I’m 5’4in. If I’m due for a urine cup test, will I pass???

    I’m a heavy smoker- bongs daily- On may 1st I failed a company wide pop drug test. They suspended me pending a clean test. I bought all kinds of detox kits, tried everything (infrared saunas, steam, working out daily, sweating any way I can etc). I took an at home test 3 weeks after the failed test, and it still came back as positive. If I had only been a coke head or heroin junky!! I am goin to do a self-pay drug test at the hospital so I can get the results and see how much time I have left.
    Don’t waste your money on Detox kits- they don’t work.

      As long as you have fat in your body THC will stay longer…. If you have body like Bruce Lee had you would be in the clear within 2 weeks…. I can see only way out in natural processes and trying to breathe a lot (sports) as thats what burns fat – oxygen … so go straight , plenty of water, fresh air, exercises, yea Sauna , clean life and clean food… fruit and veggies… no sugar no alcohol no processed food and fats…. I am sure you can make it and off course, at the last day, just before the test you drink tons of water that evening and if test is in the morning then 2 litres an hour before the test as your metabolism will just get rid of the excessive water so Pee would come out cleaner….

    I tested clean on a home test from E-bay and Amazon on day 13. I smoked 1-2 times per week the last 3 weeks, and 4-5 times a week for the 5 weeks before that. I just drank a lot of Gatoraid & Poweraid, a LITTLE water, a jug of green tea spread over 3 days, and ate light. I was surprised I passed, but that is all I did, except ride my bike about a mile a day for 3 days. I can testify that unless you are a HEAVY smoker, this will work!! I am 54 years old, 5′ 10″ tall and weigh 181 lbs. I hope this helps, and will put your mind at ease. I did it to find a new job.

    I haven’t smoked in 13months but broke that on the night before 4/20. I smoked maybe two blunts(divided into 3 ppl) and then also smoked on 4/20 and a little bit this morning. I use to smoke avidly 13 months ago because I had my medical card. Once I stopped it took a very long time to get the THC out of my system, like two and a half months and even then I still had trace amount went I applied for a job. My question is will the THC-COOH exit my system quicker since I’ve only been smoking for 2.5days and have only smoked maybe 3grams overall more or less?..?

    I’m pretty sure my doctor may test me the next time I go in so I want to schedule my appointment accordingly.

    I am 50 something female, 5’3″, 160 lbs. been smoking daily for almost 40 years. Need new job so had to quit. I bought some tests from Walgreens for about $7 each. Testing weekly and finally after 8 weeks, came out clean. Whew. Btw – just got a new job and they didn’t test.

  6. I found tests at rite aid and the more u test for the more it costs.. A marijuana test is about $16 there.. But at the family dollar they have the same type of test that Ik works and it’s only for pot.. That test is $1!!!

      Are you a thin guy? Maybe even underweight? THC-COOH is fat-soluable, so if you have a very low BMI you likely didn’t store a lot of it in your system to begin with.

    haven’t smoked for 30 days although i continued to be around it daily ( my husband is an avid smoker), i was a regular user about 3 dutches a night to help me sleep. Did a home marijuana test today and it was still positive, i’m about 180lbs and 5’6″, i drink about 3 liters of water daily.. But i still smoke cigs. if i retest in 15 days should it be at least non detectable by the home test.

If you are thinking of changing jobs give yourself 6 months if you smoke quality weed in high quantities daily. Buy home tests… they are cheap!

        so you have to be skinny to pass in as little as two weeks and if you are over weight it could be a year before you come up clean so unfair so if you are over weight you have to lose weigh and will be able to pass in two weeks. or wait a year at same weight abstaining and still not pass if too obese. no wonder drug addicts are skinny faster to pass a drug test.

      You can find fake pee in many places. It’s about $40 but idk if they’d just sell it anywhere. That’s a way you can do it, but I don’t have much other help then if you can’t get some, try to flush your body out using cranberry juice and peeing pretty frequently. Also. If you smoke cigs, it will lock the weed down for longer than it should. If you’re completely willing to quit for a minute, quit all smoking, and then if u smoke u can go back.

      You shouldn’t have any problem. Drink a lot of water up until 2 days before because they can tell if ur drinking to much water. Its called watered down. Of you only smoke occasionally and haven’t smoked in say a month or two it will be out of your system. It all depends on when was the last time u smoked before this time and how much u have smoked in the prior times. Good luck but u will be fine.

      Probably about a week from the time you smoked. Right before the piss test drink alot of water. By alot I mean around a gallon over a few hours. Pee twice. The third piss should be really clear. That’s the one you want to put in the cup. If you really want to know if you’ll pass, go to Walgreens and get a test kit and test yourself so there’s no doubts.

    First, when you smoke or do some other drugs they are basically mixed in with the protiens and such that your hair and nails grow from. so all the hairs that are growing or about to grow when you use contain the evidence of that use. It’s pretty much a part of the hair and the only way to be rid of it is to lose the hair.
    I didn’t know about the saliva test, but It sound like it could solve the work place and dui issues I’ve heard of. in states where it is legal. Just as drinkers must avoid drinking for a certain period of time before driving or working, I think smokers should be able to abstain for periods of 12 – 15 hours for safety as well. And the saliva test seems like it could be the way to allow authority to be able to know if someone is “currently” intoxicated or not.

  9. When you’re going to apply for a job, try to figure out when the drug test is. Use the above guidelines. Order mega cleanse online if you’re worried ($100, takes a week). Before the test, or even applying, pay $50 for your own, private, 5-panel drug test so that there will be no surprises.

    You can buy an herbal supplement at GNC called :Cleansing Formula”. It’s a little expensive, but it really works. I’ve smoked pot the night before a piss test and it came out clean. Here’s how it works. Carry 12 of the herbal tablets with you at all times. If you’re called upon to take a drug test, begin taking these tablets in groups of threes a hour before your test time. You can stall, it’s easy. Take 3 tablets every 15 minutes with a pint of water until you’ve taken all 12 of them.. When you go into the bathroom to pee in the container, allow your stream to flow for 3 or 4 seconds before you actually pee into the container. Then only give the minimum amount. If you do all these things correctly, you should pass the test. I’ve taken three or four tests in this manner and passed every one of them.

    When I was in the Army, the way we would beat the urinealysis was we would keep a packet of regular table salt in our shorts. If called on to whiz in a cup get some of the salt on your finger and let the urine stream run off it and pass the salt into the sample. What this did was guarantee the sample would be kicked out for having been adulterated and within 30 days we knew we would be retested, then use the time to stay clean so you could guarantee passing the next test. Hope this helps beat what is an obvious invasion of privacy!

    i was a flight attendant working a flight to amsterdam. a passenger on the flight introduced himself as an attorney and started discussing the absurdness of airlines testing employees for THC. he said you could test negative for alcohol before a flight and have a couple drinks in the airplane lavatory and be tested again when you land and no one would be the wiser. he went on to say that THC on the other hand would get you busted even if you had it while on vacation a month earlier and that was ludicrous.

    personally i don’t smoke or drink…i’m just sayin’

    BTW: 8 people die everyday in the US from alcohol poisoning. no one has ever died from THC poising. either booze should be illegal or pot legalized. it is currently categorized as a class 1 narcotic along with heroin. meth is a class 2. common sense is not so common.

    The THC-COOH is deteced in Urine from the fatty tissue on the walls of your kidneys, bladder and urinary track. Your first pee in the morning is the most potent as it’s been stored hot for many hours.
    1. Drink 16 oz of water or Cranberry.
    2. Bring 16 oz of Cranberry juice to a boil.
    3. Remove from heat, add package of Fruit Pectin (for firming jams/jellly… find in jello aisle)
    4. Drink as soon as possible without burning your self
    5. Drink 16 oz of water or Cranberry.
    6. Take vitamin B-12 for odor and color so urine won’t be clear and suspicious.
    7. Your urine will be THC free for about 3 hours after you’ve pee’d twice. Continue sipping water and vitamin B-12

    The fruit pectin will pass through your stomach quickly because of the volume of fluids initiated by the first drink.
    It will form a thin layer of gelatin on the lining of your system and block the fatty tissue from transferring the oil based molecules.You will have a full bladder. Visit the bathroom before entering the lab because they often keep you waiting a while to analyze body language.

    There are no “quick fixes”. Do not buy any of the “flush” products. They are an expensive scam and they don’t work. And you cannot “flush” your system with water, vinegar, or dandelion root either (although dandelions can be made into an interesting wine). That is because the metabolite created (THC-COOH) ends up residing in your body FAT- not in your bladder (or liver for that matter). Fluid flushing is only (partially) effective if you do not use very often and your overall plan is to dilute your sample.
    The best plan is as stated in the article- QUIT for as long as it takes for your system to clean itself up based on the scientific data. You can speed up the process (slightly depending on your BMI) if you get lots of exercise that makes you sweat and burn fat. Good luck.

          It releases the THC, stored in your fat cells that you burn while working out, into your system. That then goes into your urine… Which goes into the cup… Increasing the likely hood you’ll pop over the 50ng/ml cutoff of most tests.

            You can still exercise up to a day before your test. Think of it this way your body stores metabolites in the fat. You can ether release these by burning the fat or store them by burning only food. These are only detected when they are released. There are two situations that are hypothetically possible.

            One you smoke every hour with literally only a day before the test break, but you are gluttonous always eating and your body never touches its fat reserves. By the time you are tested there are no metabolites available to be detected.

            Two you are overweight and stopped smoking 3 months ago, however you put on all your weight while being a user. With your decreased appetite and increased activity levels you are starting to chip away at your fat reserves. You then test positive because the metabolites are circulating in your system.

Most of the “drug buster kits’ use it , but no reason to pay 50-80 for a kit when you can buy the same stuff less than 10 and follow the same routine.

    Easier just to quit for 30 days, as most drug test have variance factors to adjust for vegetarians, motrin takers, etc. that can also cause false positives and “lawsuits” which these testing companies , being scam ops want to avoid.

    Eating poo right before a test helps too but you’ll be accused of being full of $hit!

    To expedite flushing process, if you go to the gym, after your work out, use the sauna for 20 mins every day. If you have time, try 15 mins, take a break to cool off and then another 15 mins. Obviously don’t use the sauna too long…listen to your body.

    I was in the Army from ’05 to ’09 stationed at fort Bragg NC. A few friends and I smoked in the barracks DAILY. We also received random drug testing monthly. We all used a detox drink called Ultimate Gold. I recommended this drink based off experience being on probation as a minor. If you follow the instructions on the bottle exactly, you’re probably 95% likely to pass a urine test. I never failed once using this product, out of many, many tests. Hope this helps someone else.

    Chinese justice is a better way to address the problem of a pot head society. Drug testing is too mild.

    I found a website before that said to drink a lot of water, and the morning of your test, take 4 regular aspirin. I passed a urine test using this method after smoking 3 days earlier. I don’t know the reason, but it did work for me.

    Apple cider vinegar in moderation will breakdown some of the chemical they look for also. But, remember in moderation!
