‘How long does weed (THC) stay in your urine?’ This is one of the most popular questions we receive on our website, Twitter and YouTube channel.
If you want to increase your chance of passing your next urine drug test to the highest odds possible, you need to know when you will become “clean” from THC from the time you had your last joint.
In this article, we will be talking about: (1) estimated THC detection period in urine data; and (2) how to choose the right approach for cleaning the body of THC, knowing the estimated length of THC detection time in urine.
First, the THC detection period in urine depends on different factors such as a user’s body weight, life style, individual metabolism and how often marijuana is consumed.
There are several important numbers you need to know in order to choose the right approach to pass your urine drug test.
Following are the estimated THC detection periods in urine for different type of THC toxic exposure.
Estimated THC Detection Period in Urine Data.
| THC Toxic Exposure | Estimated Length of THC
Detection Period in Urine |
| Light | up to 4 days |
| Moderate | up to 10 days |
| Heavy | up to 30 days |
| Extreme Heavy | from 45 to 90 days |
Light THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana only a few times, or just tried it once, within the past 30 days.
Moderate THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana occasionally within the past 30 days.
Heavy THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana several times a week including the past 30 days.
Extreme Heavy THC Toxic Exposure – usually present in a marijuana user who has consumed marijuana every day including the past 30 days.
Many weed users are confused as to why they cannot find the exact answer to their question: ‘When will I be clean from THC?’ Users provide as much of their case details as possible: body weight, life style, metabolism, how often they consumed marijuana. etc.
“Magic” Formula.
We have even seen websites stating they have “magic” formulas, using statistical historic data, to calculate marijuana users’ THC detection period in urine.
However, as there are at least four variables in such “magic” formulas, their results may be far from accurate.
For example:
• The more fat you have in your body, the more THC spreads around – the ‘body weight variable’.
• The more active you practice physical activities, the less THC stays in your body since you keep losing fat cells– the ‘life style variable’.
• The faster your metabolism, the easier THC cleans out of your body – the ‘metabolism variable’.
• The more you smoke, the more THC stores in your body fat cells – the ‘how often you consume marijuana variable’.
To have a better understanding as to why it is not possible to get an exact answer to your question, you need to have a clear picture of what happens in your body after using marijuana.
After you consume marijuana, THC, a chemical compound found in the cannabis (“marijuana”), gets stored in the body 
fat cells in every part of your body.
When your body later uses those fat cells, the THC is released into the blood stream, metabolized and passed into your urine and hair.
According Wikipedia, THC and its major (inactive) metabolite, THC-COOH, can be measured in blood, urine, hair, saliva and sweat.
Urine contains mostly THC-COOH, while oral fluids and sweat contain primarily THC. Hair and blood may contain both substances.
Second, knowing the estimated length of your THC detection period in urine should help to choose the right approach of cleaning your body from THC.
There are many well known approaches that can help you rid THC from your body fat cells.
Depending on how much time you have till your urine drug test, you can take one of the following approaches.
4 Approaches of Cleaning Your Body from THC.
Enough Time before Your Urine Drug Test.
1.If you have enough time before your urine drug test, you have two options as how to clean up your body from THC:
-
Waiting to clean your body naturally.
THC will clear out of your system naturally over a period of time. You just to need to determine what kind of smoker you are and wait patiently for the THC to clear based on the estimated time presented in the table above.
For example, if you have smoked only a couple of times in the past 30 days, you most likely have a Light THC Toxic exposure. Estimated Length of THC Detection Period in Urine for a user with a Light THC Toxic exposure is up to 4 days.
So, you need to abstain from marijuana for 4 days before your test and your body should be clean from THC. You always can check the results with a home drug test.
-
Cleaning your body through exercise and special diet.
If you would like to expedite the natural THC cleaning process by several days, you may start detoxing your body through aerobic exercises several hours a day along with spending time in a sauna and healthy diet.

Not Enough Time before Your Urine Drug Test.
2. If you are running out of time before your urine drug test, you have the following two options as how to clean your body from THC:
-
Detoxing your body with home remedies.
You can find many popular home remedies recipes online with hundreds of users’ testimonials claiming that they have use a certain home remedy and successfully passed their urine drug test.
However, if you dig closer into their claims, you will find as many unhappy stories of people failing their drug test using these home remedies. Trying to save money, weed lovers keep using old popular recipes such as Certo, and a relatively new one – Palo Azul Tea.
We have not seen any actual proven facts that any of the home remedies recipes are reliable approaches for most marijuana users.

-
Using reliable detox products.
We have seen many negative testimonials on detox products in different forums. Many users failed their drug test using such products because they did not know what products to choose and how to use the products.
The key for success is to take into consideration the following three factors:
1. how much you smoke,
2. how much time you have before your drug test, and
3. how reliable the distributing company is.
In addition, it is imperative to check product and a company reviews.

Parker F says
I smoked nearly two weeks ago (took 2 hits of a geeb) , I am a 5’10 190 LB male. I am not a frequent smoker whatsoever (maybe 5-6 times in my life). I also have been working out 2-3 times a week and drinking lots of water. Aswell as hitting the suana twice in the gym, should I be okay for my test in 3 days.
DetoxJohn says
Parker..I think you should already become clean by now. I would recommend checking your THC levels with a home urine drug test today. This will show the outcome of your actual urine drug test. Hope this helps, DetoxJohn
gary says
I had not smoked for over a month, then smoked less than a gram of potent marijuana over a 4 day period. I am 6’1″ and 185 lbs. It has been two weeks since I smoked that small amount. What are the rough odds I will pass a urine screen now?
Thank you
DetoxJohn says
Gary..If you were a moderate user during last 3 months, you should have already become clean by now. I would recommend checking your THC levels with a home urine drug test tonight. This will show where you stand and what you should do next. However, if you were a heavy user, there is a high chance that you will still test positive for THC. Hope this helps and good luck with your test. DetoxJohn
gary says
Thank you
Ginger says
What about if you have blood and urine to do?
DetoxJohn says
Ginger..Marijuana is detectable in the blood for heavy users up to 7 days since their last use. In urine: 4-5 days- light users, up to 10 days-moderate users and from 35 up to 90 days for heavy users. If you like to get more detailed answer for your case, please come back to me with more details like your Bio, smoking history during last 3 months and life style. Hope this helps, DetoxJohn
Shanin Bhansali says
So, over the last four days I have consumed a six small joints over the course of the last three days. The joints were probably .1-.2 each. Smoked marijuana 8-7 days before in a .1 J. I weight around 198 and 5’10.
How long before I’ll be able to pass the 20ng cutoff?
Please help me, I’m desperate and scared at this point. I have 18 days to detox
DetoxJohn says
Shanin..It might take longer than 18 days to drop your THC levels below 20 ng/ml cutoff levels. So, in your case, if you would like to increase your odds of passing your urine drug test, I would recommend considering completing at lest a 10 day whole body detox program. Please read all details about the program here.
After completing the program, don’t forget checking your THC levels with a sensitive home urine drug test. You can find such tests on many online stores including amazon.
Hope this helps,
DetoxJohn
Ed says
I haven’t smoked in 60 days and was a moderate to heavy user. I have a big body 6’/ 300 pounds but have changed my diet and I excersice daily (3 mile walks and resistant training) since the new year. I drink 96-120 oz. of water a day and have lost 40 pounds since. I have a test tomorrow and have the QCarbo32.
DetoxJohn says
Ed… I think your odds of passing your urine test tomorrow with QCarbo32 are 70/30 because of your heavy THC exposure and extra weight. I would recommend checking your THC levels with a home urine drug test in one hour after drinking QCarbo32. This will show where you stand and what you should do next.
Good luck with your test tomorrow.

tom says
I have been vaping thc for 30 straight days due to boredom from the corona epidemic , i started exercising everyday for an hour walking/jogging and sweating profusely in the heat, i’ve been drinking about 2000 to 3000ml of water daily and peeing so many times due to that and im eating healthy such as fruits, vegetables and roasted chicken im 5.8 and weight 174pounds
how long would it take for me to pass the blood and urine test, i dont know when they will call for me to do the test but i estimate between a 1 to 2 weeks can i still pass?
DetoxJohn says
Tom.. You shouldn’t have any problems with passing blood drug test in a week as marijuana is detectable in the blood for heavy users up to 7 days since their last use.
However, you have a high chance to test positive for THC on your urine drug test especially because you have been vaping for last 30 days.
If you would like significantly speed your natural body detoxification process, you might consider completing a 10 day Toxin Rid whole body detox program. Please read more details and our recommendations in our detox program review here.
If you won’t have time to complete a 10 day detox program, I have seen that some heavy users try using synthetic urine as their backup plan, if the urine drug test is unsupervised.
Hope this answers your questions and good luck with your test.

tom says
thank you for the feedback unfortunately the product is going to take a while till it reaches and the test could be any day now, i am still interested in buying though since its basically future proof for other future jobs that i might come across
but for now i really would like to know, how come what im doing is not enough? how long will it stay in my body? i really had high hopes that what im doing is flushing the thc faster, ive been drinking apple vinegar twice a day for over 4 days, how long do you estimate for it staying in my body over what im doing? am i idleast speeding up the process?
DetoxJohn says
Tom..With your THC exposure, you might test positive for THC from 35 up to 65 days since your last time of use as THC accumulates in your body fat cells over a period of time.
Your natural body detoxification approach is definitely helpful, but I am afraid it won’t be effective enough to drop your THC levels below cutoff levels before your drug test day. As you don’t have enough time to complete a 10 day detox program, as mentioned before I have seen that some users try using synthetic urine as their emergency plan, if the urine drug test is unsupervised.
Hope this answers your questions,

Joe says
i have smoked THC vape weed for a whole month but stopped cold turkey as i have an upcoming urine test soon, i have been clean for over 5 weeks 36 days to be specific, i exercised just 2 straight weeks, lost about 5kg went from 81kg down to 76kg and my hight is 5’9
i also drink alots of water no less then 4000ml of water every single day and cranberry juice to go with my dinner, am i safe? will i pass my urine test? please let me know thank you.
DetoxJohn says
Joe..There is a chance that you might still test positive for THC because you vaped for a month. I would recommend checking your THC levels with a home urine drug test tonight and go from there. If you still test positive, you either consider completing a 3-5 days whole body detox program or if you don’t have enough time until your test, on your drug test day you might try using a detox drink like Mega Clean.
Don’t forget getting a few extra home urine drug tests. This will help to find out when you will become clean.
Hope this helps,
DetoxJohn

Rebecca says
Hello there, I’m 5’2” weight is 134 and my BMI is 24.5. I took a tiny dosage of my friend’s rso to help with stress. I even licked half of it off because I had to drive home. I took this dosage last Wednesday and I have to take a drug test by this Friday. I have dance practice 2 times a week so I do have physical activities. What are my chances?
DetoxJohn says
Rebecca..I think you should have become clean by now. I would recommend checking your THC levels with a home urine drug test tomorrow morning. You can find such tests at any drug stores.This will show if you can pass it or not.
Hope this helps and good luck with your test results.

Julie says
Hi! I’m definitely not very well versed in the marijuana world. I’ve used randomly in the last three months. Most recently was a week ago and just one hit off of a bowl. Before that it’d be two or three hits once every two weeks.
Everyone says I’m clean now because I’m so small (5’9 155lbs) and I barely used but I want to begin processing For the military. Best recommendation for how long I should wait? Would an at home test suffice in showing if I’d pass theirs?
DetoxJohn says
Julie..Though I understand your goals, you put me in an awkward position when you mention the reason for your test. It is our policy not to answer these questions for legal reasons.
I hope other users read this and understand that there is a point where too much information may put me in a position where I cannot answer their questions.
In general, light/moderate users become clean within 5-10 days since their last time of use.
Using a home urine drug test helps to understand where you stand now.
