How Long Does Weed Stay In Your System? (+Calculator)

“I’m a 6’2” man and have 178 lbs. I have a drug test in 4 days, haven’t been smoking weed for a week. Will I pass a drug test? I have a regular cannabis smoking habit.”

The most common standard urine drug test can detect THC up to 90 days after inhalation/ingestion. Does that mean that everybody who has smoked a joint in the last 90 days will test THC positive? Of course not; it depends on how frequently you smoke, M/F and how much you weigh.

Obviously, you can also quicken up the speed of THC elimination with complete THC detox kits, or even completely forgo the detox process by using synthetic urine for a drug test.

So if not 90 days, how long does weed stay in your body?

We looked into published scientific studies about how long does weed stay in your system. The goal of looking at more than 6000 gathered and tested urine samples was to answer how many days of marijuana abstinence is needed to pass a drug test for various subjects (male/female, underweight/overweight, one time users as well as chronic users).

test tubes with urine prepared for urine drug testing of marijuana
Testing urine samples by users with different weight, height, habit, sex and activity levels can help up determine how long does THC stay in our bodies.

The speed of weed elimination can be roughly estimated for every type of user:

  • Male and female.
  • One-time puffers all the way to heavy chronic marijuana users.
  • Underweight people (skinny guys and girls with low body fat mass percentage) and overweight people (for example, an individual weighing 300 lbs passing a drug test is increasingly difficult).

In the end, you should know when will weed be cleansed out of your system if you’re a chronic user, a skinny woman, a fat man, somebody with over 200 pounds or a one-time user will less than 100 pounds. And everything in between, of course.

Calculator – How Many Days Does THC Stay In Your System

After helping out almost 200 people (in the comments), we have decided to put together a THC elimination calculator. You can input your sex, weight, height, metabolism and activity levels.

The calculator will give you a rough estimate of how long it will take for all the THC to be cleared out of your system for all times of users: light, moderate, frequent, heavy and chronic heavy.

You can use the calculator freely. Just keep in mind we are all unique and our system retains THC differently. These are only rough estimates.

Weed Elimination Times

Weed might be great for a number of reasons but THC elimination time is definitely not one of them.

Most of the other drugs (even hard drugs) leave our system in 1-3 days after ingestion. Unfortunately, marijuana can accumulate in your body and it takes significantly longer time to leave the system.

How long does weed stay in your system?

Simple short answer: 1 to 90 days.

Simple long(er) answer: 

  • One-time smokers: 2-7 days.
  • “Weekend” smokers (1 joint/week): 5-10 days.
  • Moderate smokers (3 joints/week): 10-17 days.
  • Chronic smokers (7 joints/week): 17-30 days.
  • Heavy chronic use (more than 10 joints/week): 30-48 days.

Scientific answer: It depends. Did you smoke just once or are you a chronic user? How tall are you and how much do you weigh? Male or female? What kind of a drug test are we talking about – urine test or hair test? What are your levels of physical activity and body fat mass?

We’ve prepared conglomerated lists of THC elimination times for men (tall, normal, short) and women (tall, normal, short).

For example, here is a list of estimated THC elimination times for an average high male (5’6” – 6’2”):

Average Height Male (5’6” – 6’2”)

Average Male (5’6” – 6’2”)150-200 lbs200-250 lbs250-300 lbs300+ lbsRecommended Detox:

10+ joints per week33 days

You can find 5 more THC elimination lists for down below.

These include:

  1. Tall male(above 6’2”)
  2. Short male (below 5’6”)
  3. Tall female (above 5’7”)
  4. Average height female (5’1” – 5’7”)
  5. Short female (below 5’1”)

Scientifically speaking there are a great number of factors that determine how long does it take for marijuana to leave our bodies.

For example, people with higher BMI (body mass index) test positive for THC days or even week longer than people with lower BMI.

To simplify it, we boiled down some research studies into simple enough figures for THC detection in urine. More than 90% of drug screening test urine for weed. If you’re faced with a lab test, you will almost certainly have to ‘pee in a cup’.

We do also assume you were smoking ‘some good sh*t’ (that translates into 3.55% THC cigarettes).

How Long Is Weed Present In Your Urine?

Most of the time when people talk about drug tests, they talk about the urine drug test.

Testing urine for marijuana (THC-COOH metabolite to be exact) is the standard procedure that employers use in order to determine if you’ve been using cannabis.

The length of time weed can be detected in urine is quite a disputed topic. We have two extreme anecdotal cases:

  1. “I’m get blazed all the time (loading some fat ones) and passed a lab test 3 days after my last joint with flying colors, bro.”
  2. “Went to Amsterdam, smoked a joint just to try it (that stuff was really good). A month later, I failed a drug test and was fired on the spot.”

Weed leaves your body in 3 days or in a month: which is it?

Sure, there are lots of this kind of anecdotal cases but nobody really likes to risk his or her job with something as serious as failing a drug test.

That’s why we used the result of a clinical study published in the renowned Journal Of Analytical Toxicology to base the calculation of how many days it takes for weed to leave your body.

The number of evaluated urine samples exceeded 6,000 individual samples.

The THC elimination times are categorized based on sex, height, weight and smoking habit.

That’s how everybody can find themselves in the tables below and get a good grip on how long does it take for weed to stay in their individual body.

After that, you can check out how to do a complete THC detox in order to cut the time it takes for THC to leave the body in half (or even more).

Tall Male (Above 6’2”)

With each of these cases, we segmented how long it takes for weed to leave your body by two factors:

  1. Weight.
  2. Cannabis smoking frequency.

Example: If you’re a tall male (above 6’2”) with a moderate smoking habit (3 joints a week) and weigh 198 pounds, the best estimate of how many days does weed stay in your system is 12.3 days.

Here is the estimation table of days after which weed is likely not detected in the urine of a tall man:

Tall Male (Above 6’2”)150-200 lbs200-250 lbs250-300 lbs300+ lbs
1 joint once2 days2.6 days3.3 days4 days
1 joint per week5 days5.7 days6.5 days7.3 days

7 joints per week17 days19.8 days22.3 days25.7 days
10+ joints per week30 days32.9 days36 days39.1 days


Based on this data, we can answer the initial question. Here are the case data:

  • Height: 6’2” (tall man)
  • Weight: 178 pounds (fits into the 150-200 lbs segment)
  • Days of abstinence: Haven’t smoked for a week and has an upcoming urine drug screening for marijuana in 4 days (11 days total).
  • Smoking habit: Regular smoking habit should fit 3 joints/week category.

How long does it take for the weed to leave his body?

According to the rough estimates in the table, such an individual should pass a urine drug test in 10 days.

That’s how we can say with high probability that such an individual should pass a standard laboratory drug test for marijuana.

If, for example, he would hit the bong 7 times per week, the THC would sufficiently leave his body to pass a drug test in about 17 days. If this were the case, such an individual would most probably fail a urine drug test.

The following tables include calculated rough estimates of how long does THC stay in the body for other types of bodies:

How To Calculate The Time It Takes For Weed To Leave The Body?

THC elimination times vary quite a lot between individuals.

Numerous studies were conducted producing non-coherent results. However, there is a silver lining connecting a majority of conducted studies of THC elimination speed.

Namely, certain ‘rules’ were observed:

  1. The heavier the smoking habit, the longer it takes for our system to eliminate THC.
  2. Higher BMI leads to longer elimination times. That’s why heavier people need longer time to detox.
  3. Higher body fat percentage leads to a prolonged time it takes for weed to leave the body. Because the total body fat percentage of women is significantly higher than in man, women need to detox longer.

One important factor is also the kind of urine THC tests that are being used. In the calculations above, it was presumed that the detection of THC in urine is being conducted with a standard drug screening test with a 20 ng/ml cut-off rate. Some laboratories might also be using an older lab screening test with 50 ng/ml cut-off rate.

When calculating the period after which THC is no longer detected in urine, the following factors were taken into the account:

  • Smoking habit.
  • Sex.
  • BMI (as a conglomerate of height and weight).

Based on those and the available data from clinical studies the extrapolations (mostly linear) can be drafted.

Nonetheless, it is very important to understand that the THC elimination data in the tables are merely rough estimates and cannot 100% guarantee somebody with a certain body constitution, sex and smoking habit will pass or fail a drug test.

Share How Many Days It Took You To Detox From THC

If you have a personal experience and can shine a light at how long does it take for weed to leave the body, you can share it in the comments.

Example: “I passed a drug test despite being a heavy user (5’7”, male, 210 lbs). Did the whole abstinence thing and drank gallons of water for 15 days, passed with flying colors.”

Alternatively, if you have a question about your individual case, you can also place a comment that looks something like this:

“I have a drug test in 3 days, haven’t smoked for 5 days, will I pass? I’m 6’1” man, weigh 213 lbs and have been smoking 3 joints per week for ages.”

    • 2 puffs of a vape, in most scientific language, is an insignificant amount of THC. Of course, it does depend on how well you’ve inhaled, how THC-rich was the vape as well as your weight/height; however, the chances of a standard urine drug test to detect 2 puffs are near 0%.

      Reply
    • Given your small physique, the THC from your body should eliminate faster. However, given the amount (7-14 joints), there is a considerable chance of failing a standard urine drug test after 30 days without.

    Reply
    • Hello Jessica, thank you for the question. 75 days is a long time; it is extremely unlikely for your system to still have enough THC (and THC-COOH metabolite) to be detectable by standard urinary analysis. After the 45th day, almost everybody is clean. Just to soothe your worries, you can pick up a home drug test at your local pharmacy and test yourself just to be sure.

  2. I’m a male 5’8 150 roughly 7-9% body fat( I lift a lot so I’m assuming that’s where I’m at) and I take one hit from my vape every night before I go to sleep. Have a drug test in five days. Is it possible to pass if I sweat a bunch and drink a bunch of water?

    Reply
    • Given the extremely low body fat, you have much better chances (THC is soluble in body fat where it can accumulate over time). It is possible to pass by doing a natural detox (sweating, dieting, water); however, do test yourself with a self-administered drug test (get one at your local pharmacy) to be sure you’re not positive. Chances are that there is enough THC accumulated in your body fat that 5 days won’t cut it.

  3. I quit having my nightly vape about 90 days ago however I went out one night about 10 days ago and took about four giant hits of some high quality stuff. I have a drug test in 2 weeks so that will put me at around 21 days. I am 5’6 and weigh 210 however I have been on a diet plan and losing weight (about 2lbs per week). Should I stop losing right before the test? Is that “releasing” the store up THC in my fat cells?

  5. I’ve been a daily smoker for about 5 months. I’m 5’3 and weight around 150 or less. Not super active though. I’ve stopped for just about three weeks now. I could possibly have a test in a week. Do you think I’ll be able to pass if I’m tested? I don’t want to use those drinks either, I’ve failed using one and wasn’t a daily smoker at the time.

    Reply
    • Hello Maddie, thank you for your question. Smoking for 5 months on a daily basis with a body mass index above 26 is a recipe for quite a long THC elimination process. During those 5 months, THC has been accumulating in your fat tissue and it is less than likely that all of it will leave your system in 4 weeks.

      Detox drinks do have a questionable effect; if you truly want to increase your chances of passing a urinary drug analysis substantially, you should look into our article about Complete THC Detox. It does, however, involve physical activity, specific dieting and a trio of detox pills, liquid and fiber.

      Based on all the info, you do have a slim chance of passing a drug test but, fortunately, if you have a week left you can do something to drastically increase the likelihood of passing a drug test. Good luck!

  6. How likely would a workplace drug test show positive if a 6’3” 300 pound male smokes half of a joint 10 days ago, but hasn’t smoked anything before or after and tested negative on a home test?

    Reply
    • Extremely unlikely, if you used the home drug test with 20 ng/ml cut-off level. The home drug tests are extremely accurate; the lab usually uses 20 or 50 ng/ml cut-off level marijuana test strips. If you used a 50 ng/ml cut-off rate one, you might be still positive (in theory) if you are tested with 20 ng/ml cut-off rate test. However, if you’ve passed 20 ng/ml, you’re as safe as you can get.

      Theory aside, it’s extremely unlikely to fail a drug test if you’ve smoked only half a joint once 10 days ago. The negative result of your home drug test is a good confirmation of that. In short, you have nothing to worry about.

  7. I’m 19 years old, 6’5 and 190 lbs or so i wanna say I’m around 13% body fat, by the chart I guess I’m either a chronic or a heavy chronic smoker going through a quarter every 5 or 6 days plus a couple dabs everyday , but I’m pretty active and my metabolism is pretty fast, i dont have a set date for my drug test but I’m wondering how long it’ll take for my system to get clean

    Reply
    • Having a low body fat percentage and being active/having a fast metabolism are two major advantages. If you’re a chronic user, the THC has been accumulating in your body fat BUT you don’t have that much body fat (proportional to your total weight) in addition to a quicker elimination process. This means that the quantity of THC in your body fat is lower (than the average chronic user) and it will be flushed out of your body quicker.

      Chronic users are on average found THC positive 17-30 days (rough estimate) after the last use. Given your advantages, you should be looking at 17-20 days of elimination time. If you can increase your physical activity and do a proper THC detox diet you might even pass a standard urinary drug test in 15 days.

    • Thank you for the question. 1/3 of 2 joints is not a lot of THC; you have very little to worry about.

      Drinking water and physical activity is a good way to flush the THC out of your system. However, make sure you increase the calorie intake dramatically a day or two before a drug test. This should slow down the release of any THC leftover in your fat tissue.

I’m also pretty active because of the field of work I’m in, however, I do eat terribly because of the time of night I get off.

    Reply
    • The bad news is that, being a heavy smoker, you could fail a drug test despite a month of abstinence (THC has accumulated in your fat tissue over time).
      The good news is that you can do something about it because you have about 3 weeks of time left before the drug test. Here’s what you do:

      1. Buy some home drug tests (get a pack of 5 or 10, should cost about $10-$20 at your local pharmacy).
      2. Test yourself. If negative, you should pass any standard urinary drug analysis. If positive, proceed to step 3.
      3. Start detoxing. Check out the section ‘3rd Way: Complete Detox Formula’ in the article about THC detox here. The complete detox should include dieting, physical activity and pre-rid detox pills.
      4. Test yourself every few days. If negative, you are clean and shouldn’t worry about it. If positive, keep up the detox.

      With your body constitution and being a ‘super heavy smoker’ it might take a while for all of the THC to leave your body. However, if you dedicate yourself to dieting, physical activity and fasten the elimination process via pre-rid pills, you will drastically increase your chances of passing.

      Just make sure to confirm if and when you’re negative with home drug tests.

    • Hello Dony, 47-50 days is usually more than enough to eliminate all the THC out of your system. Only heavy smokers need to be careful; your body constitution and physical activity are two major advantages when it comes to passing a drug test. Continue with the 4 times per week gym sessions, plenty of water, check yourself with a home drug test and be sure to consume a high-calorie diet a day or two before a test.

    • The THC elimination time has a lot to do with your fat body percentage and total fat weight. You have a BMI of 19.5 which is great; the THC will go out of your body faster than from an average body.

      Presuming you’re a male with a high level of physical activity, and a heavy smoker, you’re looking at 25-32 days. But as always, this is just a rough estimate; the smartest way to check if you’re really clean is a home drug test.

      Reply
    • Hello Chris, thank you for the question.

      There is only a small pool of documented test subjects that have tested positive for THC 60 days after their last joint. However, the THC has been accumulating in your fat tissue for some years and the 3-4 joints/day is a large quantity inhalation of THC on a daily basis.

      You should probably check our article about the Best THC Detox Practices; dieting, physical activity, and Toxin Rid detox while testing yourself several times and eating up day or two before a drug test is the best advice to flush the THC out of your system.

    • Hello Rick, thank you for the question. I would be concerned that due to high BMI, your body would store THC for longer. However, the 3 negative home drug tests speak for themselves; especially if you used the ones with 20 ng/ml cut off rate.

          • Hello Victoria, the THC from prior smoking is the question here. If it’s all gone, you will pass a drug test within a week. If not, you should wait for about 3 weeks to be safe.

    • You don’t have to worry too much. 4 puffs don’t contain a significant amount of THC, your BMI is very low and 18 days should be enough for all the THC to leave your body.

  15. I ate two edible cookies two weeks ago and potentially have a drug text in two weeks. I am 5’2”, female, 210 pounds. I recently cut carbs from my diet and drink about 65-80 oz of water a day. Will I pass?

    Reply
    • Hello Nila, considering those cookies can contain significant amounts of THC and your high BMI, it will take a while for all the THC to leave your body. You’re on the right track, however, drinking water and cutting carbs. Check out the Complete THC Detox Guide for the full info on the detox.

      All in all, 4 weeks is quite a long time and you have good chances of passing the drug test.

      • You’re on exactly the right part; losing THC-rich fat to get as much of the THC out of your system. Also nice job for 2 lbs per week, that’s in itself an amazing achievement. You should be losing as much of weight/fat as possible and change the diet a day or two before a drug test.

        A day or two before a drug test, you should be enjoying a high-calorie diet (at least 4000 kcal, preferably carbs and fats). This will prompt your body into building fat again and as a result the THC that might still remain in your fat cells will stay there (won’t enter the bloodstream, kidneys and ultimately be found in your urine).

  17. 5’9 195lb female- not active enough to say so and I tend to eat my feelings, of which there are MANY lol.

    I was definitely a heavy smoker for most of the past couple of years. This April I had quit for a drug test in May and failed it as I was only 15 days out, I didn’t smoke again until late May and even then it was significantly less than what I had been used to (I would literally hit my vape pen all day everyday).. From May to mid June I smoked about a bowl a day, maybe split a blunt or two on the weekends between a few heads. Mid June until the first week of July I smoked nothing daily but did take a few hits on the weekends, but since July 5th nothing. My drug test is coming up, not exactly sure when but I’m counting on somewhere around August 12.
    I’m worried but think it’s likely I’ll pass, opinions?

    Reply
    • Hello Maggie, thank you for sharing your story. For heavy smokers, 15 days of abstinence is clearly not enough to pass a drug test (the failed drug test can attest to that). You have better chances now because of the lowered amount of THC inhaled, THC stores accumulated in your fat tissue are currently being depleted and you have more than 30 days between your last hit and a drug test.

      Considering all the factors, you do have about 50% chances of passing a drug test. That’s still very risky, though. You should dedicate yourself to a complete THC detox (long term solution) or even think about synthetic urine (short term solution). Given that you still have more than 2 weeks, it would be smart to check the THC detox guide here and start with the detox as soon as possible to dramatically increase your chances of passing a drug test on August 12.

    Reply
    • Hello Jessica, thank you for your question. With such a minimal THC intake, you don’t have to worry about much, especially if you have 2 full weeks between the last inhalation and the drug test.

      You should do a typical natural THC detox (without pre-rid pills, or detox drinks). Those consist of physical activity (cardio is the best), drinking water and a low-calorie diet up until two days before the test; then you switch to a high-calorie diet. Hope this helps.

They are either positive or negative; maybe re-do the test, follow the instructions and try to be as unbiased as possible when reading the lines. It should either be there, or it should not be there. But I do know that cheap drug test can be a bit “iffy”.

    Reply
    • Quite long, unfortunately. If you combine high BMI and daily use of THC, you’re could test positive even 40 days after the last bowl. To be safe, you shouldn’t be using any THC products for at least 60 days; that is without a THC detox, of course. With the right detox, you can cut that time considerably.

    • Hello Kay Dub, the June vapes are not something to be concerned about; the 4-5 daily puffs are the real problem here. You have a decent chance of passing; however, when it comes to the drug testing and everything that is at stake you really want to be at least 90% certain you’ll pass. You should start detoxing in order to increase your chances of passing a drug test – drinking water and physical activity are great, you can read more about how to do a THC detox for a drug test here.

    Reply
    • Hello Bethany. For everybody who is not a chronic user, being abstinent for 45 days should be enough; hence the likelihood of you passing the test are quite high. When you get your result back, you’re most welcome to share it here so we all can have some confirmation of your negative result.

      Reply
      • Hello there, 2 joints and 1 roach is a fairly measurable amount of THC. Given your BMI (body mass index) is above 32, your body has an above-average capacity to hold on to the THC and the elimination process is accordingly slower. It is hard to say you’re clean for a urine test with a high degree of certainty; depending on the speed of your metabolism, it is quite possible that you would have a harder time passing a drug test, given the time frame.

  29. Hi there, I’m an 180 pound female that is 5’2 with an 33 percent bmi. I took 3 hits off of a dab pen on the third of this month and was clean prior. I drink about two liters of water a day, and work in an extremely hot/ sweaty environment 3 days a week (I also have hyperhydrosa). How long do you think it would take me to get clean? I will probably have to take a 20 ng drug screen soon for a new job

    Reply
    • Hello Jessica, if you’re a one-time user, there are high chances that you would already test negative on a 20 ng drug screen. Sweating is good but it eliminates less than 10% of THC in your body (feces elimination, for comparison, constitutes about 60% of THC elimination).

      In any case, you’re probably clean already and the chances of passing a drug test are increasing every day.

I would greatly appreciate your opinion!

    • Hello Tymber, you have nothing to worry about. Nobody tests positive on a urinary drug test 117 days after their last joint. Those cheap drug tests are a bit tricky to read, I agree, but you can be certain you’ll pass your drug test. You’re more than welcome to share your test results here when you get them.

      Reply
      • Hello Jessica, your situation is quite ok. 3 weeks is usually more than enough to eliminate a ‘weekend’ amount of THC, especially if you’re not doing it during the week and the THC is being flushed out during the week (not being accumulated). You should check with home drug test if you test positive for confirmation.

        Reply
        • Hello Becca, it is normal for a daily smoker with your body composition to test positive after 22 days. If you have a week left, it would be smart if you went into a THC detox mode with drinking plenty of water, doing cardio and even use some THC pre-rid pills in order to increase your chances of passing the test.

          Reply
          • Most probably not. You should pick up a home drug test from your local pharmacy and test yourself to be sure but it’s very unlikely you’ll test positive. If you do, a bit of detoxing will go a long way.

Been smoking regularly for 9 months now. How long do you think til I’m clean. I’m also buying an in home test if you have recommendations. Thank You

    Reply
    • Hello Alex, given the chronic use for 9 months it can take anything from 30 to 60 days for you to start testing negative on a urinary drug test. Getting some home drug test is smart because it’s really the only way to check if you’re negative after 30, 40, 50 or 60 days.

      The reoccurring problem everybody seems to have with the home drug tests is the ‘faint’ line (you can’t really tell if you’re positive or negative from that). Most of the home drugs from your local pharmacy shouldn’t have this problem and some online vendor’s tests such as the ITG Labs test certainly don’t. Nonetheless, when reading the test, it’s very important that you’re objective. Some of the ‘faint’ line results are a result of, for a lack of a better scientific expression, wishful thinking.

    Reply
    • Hello Anthony, 1 joint/day can amount to quite a lot of THC over a long period of time. I would say you would need at least 2-3 weeks to have a chance at passing a standard drug test, despite the above-average physical activity. You should definitely look into THC detox to help speed up the elimination process.

    • Not a problem, we are aware of how hard it is to find accurate information about drug testing and drug elimination.

      Employers in more than 90% of cases use standard urine drug screening with 20 ng/ml or 50 ng/ml cut-off for THC-COOH concentration. These are the same ones you can get in any pharmacy; if you pass a home urine drug test, you can be almost certain you’ll pass the one given to you by your employer.

      Here’s why the high-calorie diet before the test is useful: if there is THC left in your body, it will be in your fat cells. When you consume a low-calorie diet, you burn fat and the remaining THC is slowly released in your bloodstream and can be detected in the urine.

      However, if you switch to a high-calorie diet before a test (and you should), you won’t burn fat, the remaining THC will not be so readily released into your bloodstream and the likelihood of THC being detected in your urine will decrease dramatically.

        Reply
        • Hello Ash, given the heavy chronic use and the high BMI it can take as long as 60 days. First thing’s first; you should stop smoking ASAP. You can speed up the elimination by increased hydration and physical activity to bring it down to 52-55 days (rough estimates, obviously). You can use the big 10 Day Toxin Rid Program and reduce the time down to 10 days or even opt for synthetic urine.

          All in all, the elimination time varies quite a lot in heavy chronic users and the smartest way to truly know when you’re negative is by getting several home drug tests from your local pharmacy and test yourself after 30, 40, 50, 60, 70 days.

  44. I’m 6 feet 173 pounds. I did a total body cleanse in December 2018 for 1 full month and passed a urinalysis. I smoked about 2-4 grams per week. Since February 2019 I smoke about 2 grams per week. I’m very active, walk 3-5 miles per day for conditioning, surf 3-5 times per month, play tennis a few times a month and I’m a very healthy eater with a low fat, low carb, high protein diet. I don’t consume a lot of sugars except what’s in Gatorade. I mainly drink sugarless green or black tea, coffee, and about 40 ounces of water daily. I’m very disciplined with my diet and fitness. I have been offered a new job. Once I began the interview process I abstained from smoking completely and it’s been 18 days since I last consumed. I got the job! The date of my scheduled urinalysis will give me 23 days without consuming any thc at all. I’m on a hard core work out regimen and for the last 2 weeks am averaging 7-10 miles of walking per day on top of other activities that include tennis, surfing and 3 2-mile runs. My diet is exceptional, protein rich and low in carbs and sugars. I’m also taking a 7 day super cleanse and a scoop of psyllium fiber every night with 2-3 regular bowel movements per day. Should I be concerned?

    Reply
    • Hello Chris, congratulations on getting the job. The outstanding physical activity and higher water consumption are fantastic; sadly, it will only increase the elimination of THC by about 20%. Being completely clean 23 days after consuming THC is optimistic; with everything you’re doing, I think you do have at least a 50% chance of passing. I know your diet might suffer but consider consuming 4000 kcal a day before the test and on the day of the test. If you burn fat during that period, the THC that might remain within that fat might be released into your bloodstream. If you build fat during that time, THC will remain in the fat tissue.

    • Hello Cody, thank you for sharing your concerns. It is not out of the realm of possibility for a heavy chronic user to test positive 40 days after the last use. In your case, I would try the home drug test again; 52 days is quite a long time and you should be starting to test negative anytime now (maybe you already do). There are few documented cases of chronic users testing positive even after 2 months; however, we have yet to study a subject that would be THC positive for more than 90 days. Hope this helps.

    I was a regular smoker (nightly) for about a year. For a few months I was using THC Cartridges nightly (approximately 2-4 puffs a night) then I quit using those about 6/1/19 and finished what little weed I had left (and eight or less) over the course of a month until 7/1/19.

    I quit smoking on 7/1/19 and it has been about 59 days since my last time smoking.

    I took an Equate THC Drug Test (similar to First Check), but it was incredibly hard to tell if it was positive or negative. The “C” line was a visible red line, but the “T” line was a VERY faint red line. In the instructions it said a faint line was technically a pass, but I am still worried. The Equate test was down to 50ng.

    The test will be through the DOT Drug Screen 6 panel. From what I could find, they do a 50ng test first then a confirmation 15ng test if the 50ng comes up positive.

    Thanks in advance hopefully you get a chance to answer!

    • Hello Buster, thank you for all the useful info. I have some good news; it’s almost impossible to be THC positive after 59 days of abstinence. There have been a few documented cases of heavy chronic users who have tested positive after 60 days of abstinence. You have almost nothing to worry about.

      • Hello

        Thanks for the replies, reading the responses were helpful.

        So I’m a 23 year old Male, 5’10” and weigh 155 pounds. I’ve used cartridges, and took 4-5 puffs a day for months. Last time I smoked was 3/8/20, and haven’t smoked since. I’ve got a urine test on 5/27, and was wondering if I’d pass. Also I’m not too active, probably walk a couple times a week.

        Hope you guys could find a chance to read this, but thanks for your other replies!

        • Hello John, thank you for the upbeat spirit here, it really means a lot. As far as your drug test is concerned, you don’t have much to worry about. The cumulative effect of taking 4-5 puffs a day for months is low; the THC concentration in your blood was somewhat lower than in the case of a chronic smoker. Given that you have more than 2 months between the last smoke and the drug test, you should be fine. Of course, you can check with at home drug test just to be sure and less anxious about the whole thing.

    • Hello Michaela, how long have you been abstinent? For a chronic smoker, 5 days is not nearly enough, unfortunately. There is little physical activity can do here, even a THC detox might be out of the question. When pressed in such a situation, some people use synthetic urine to pass. If you’ve been abstinent for about 30 days, you do have a fair chance at passing the test.

  52. Hi
    I have been taking 3 puffs of indica every night for over 3 years to sleep . I am 54 5ft 8 185 been off for 60 days. I bought 20 home test strips and they all started to came back clean after 30 days. I took a DOT test 3 days ago no results yet should I be worried?

    Reply
    • Hello Ken, not at all. Using home test strips was smart, given your body constitution and use it would take roughly 30 days for the THC to be completely removed from your body. You have absolutely nothing to worry about; the test results can take more than a week sometimes as well.

  55. Hi everyone.. would like opinion on pre employment DT

    Im worried to take mine. I’m 5’3 110 lbs female , and had been a regular smoker.. abt 3-4 hits of kush almost everyday for the past may – july. Roughly 1grm / week. I have little to no physical exercise but fast metabolism.

    I had stopped august 2 and been clean for 30 days.

    Is there a chance i will still test positive?

    Reply
    • Hello Fiona, during the summer months, the ingested THC has likely been stored in your tissue and it does take a while to flush it out. However, you don’t have that much fat tissue (110 lbs) which is a big advantage. It is possible you’re already THC negative; a simple home test might confirm that. If you still have time prior to the test, do check out our THC detox article and consider increasing your water intake and physical activity to further ensure you’ll pass the test.

  56. HI – I am 6’6’m and 205 pounds, exercise semi-regularly, fast metabolism, and for the past year smoked a small joint < 0.3-0.4 grams every night or every other night. I have taken a few 1-2 week breaks throughout the year, though. I stopped smoking for two weeks and had a drug test yesterday. I was worried about whether I would pass so I drank a enough water beforehand so I produced a semi-diluted sample. I took 3 at home drug test (50 ng/ml) and passed all three, taken few hours after the lab test, the following morning (first pee), and later that day. Can I trust the results of the at home drug test? – they were the cheap first choice ones.. I've read in some scientific papers the actual elimination time can be much shorter than 3 weeks – typically 10 days for regular users at the 50 ng/ml and up to 21 days at the 20 ng/ml level. Two weeks seems short but the at home test give me some comfort

    Reply
    • Hello Jackson, 2 weeks may be enough, especially if you’ve taken steps to dilute your urine. Even the cheap home drug tests can be relied on; if you’ve passed those ones, you have a high likelihood of passing the real one. The problem that could arise is that the drug test will find the urine too diluted; the specific density would be below acceptable and they would ask you to redo the test.

      Reply
      • ok, thanks for the reassurance. The lab has a week turn around before I get results (its been 5 days already). If they say i’m dilute then it would have bought me another week so that would be a plus in my books. The pee I provided was only slightly dilute – still had some color and could pass as a very hydrated person. Anyways, I passed the home test with dilute and first stream of the day pee so I think I should be good – the week turn around has given me way too much time to think about this… 😛 I find out tomorrow or the day after so ill update my post with results.

    Reply
    • Hello Loki, smoking for 2 weeks didn’t accumulate an extraordinarily large amount of THC in your fat tissue (as is the case with chronic users) and therefore 35 days might be enough. The negative result on the home drug test is a great indication you’re negative. About the faint line; we had many cases in which the intensity of the line was the issue, the results you got is almost 100% a negative result.

Haven’t smoked in 4 days and have a drug test in 9 days. I’m also doing the 3 day toxin rid this week. I only eat fish and vegetables. I know there is no exact answer however do you think I have a good chance of passing a drug test? Thank you.

    Reply
      • Hello Will, congratulations on the body fat percentage. Chronic smokers do accumulate THC in their fat tissue but you have less than average amount of fat tissue, are physically incredibly active and consume an above-average amount of fluids.
        13 days from the last joint to a drug test is cutting it close. However, with the 3-day Toxin Rid and the incredible detox dedication, you have surprisingly high chances of passing. Enjoying a high-fiber diet will only boost the Toxin Rid effectiveness (majority – about 60% of THC – is eliminated via feces and alfalfa leaf extract in Toxin Rid pre-rid pills significantly increases elimination via feces).
        Be sure to switch to a high-calorie diet a day before the test and on the day of the test to capture all the potentially remaining THC in your fat tissue.
        All in all, you have a perfect plan and thus very good chances of passing a test. Good luck!

  64. I am a 5’8” 150lb female and I smoked a joint 23 days ago. Prior to that it was infrequent, maybe 2-3 hits 2 nights on week, nothing the next, a few hits 2 nights the next week. And nothing may-July. I took a home drug test on Friday and it was negative though the bottom line was kind of faint. I took my pre employment screen today for a hospital job and do not know the results yet. Do you think there was a good chance I passed?

  65. First of all, this is the best website ever.

    So, I used to smoke a lot when I was in college (probably 2 grams a day minimum) but slowed down a lot post grad. Since summer 2018, I haven’t smoked nearly as much, but did pick it up again pretty regularly back in October/November of last year until May 2019. Maybe smoking 1/2 – 2 blunts if I was with friends a few times a week, or pretty regularly a few hits from a bowl in late spring. Since then, I haven’t smoked regularly at all but I smoked quite a bit at a festival in mid-June. Didn’t really smoke anything after that until one month ago when I took a few hits off a bowl and then again last night shared 2 blunts with 1-4 friends. I didn’t smoke at all between the two most recent uses. I feel so stupid for it now though because I woke up this morning after smoking with a brand new job offer and found out I have to pass a screening by Monday at the latest. Of course I’m not gonna smoke anymore, but really hope I have a shot at passing this test. I’m female, 5’6” and avg 164-168 lbs. Not super active but I do yoga sometimes; don’t have a great diet but have recently been cleaning it up and juicing because of a bad cold.

    Any advice is much appreciated!

  66. This website is great and so far after reading every word (ha!) has eased my worries. I’m 5’3” and 145 pounds/age 33/woman. I was a heavy smoker for years then quit for a year and a half due to a medical program. Work at a restaurant so was tempted this summer during break. I smoked a vape pen daily for about 2 months, probably 1-3 hits of it a day. Guess I’d say moderate smoker during that time. Quit for a week and then decided to partake at a concert in July. So to finally get to the point! I will have been clean for 53 days when tested at labcorp. Took an equate test, negative faint line (seems to be the norm) and then a cheapo $1 test, again even slighter faint line. My friends think I’m crazy for even being worried. Please tell me they’re right!

    Reply
    • Dear Worrywart, why so worried? Your friends are right. Several things have to be majorly wrong to test positive after 53 days (such as chronic heavy smoking, high BMI). The $1 test should be as accurate as $100 test with minute differences; I’m glad you’ve checked about that faint line issue that comes up again and again. For what I can gather, you’ve tested negative on the home drug test and you are already in the safe zone.
      Thank you for reading every word, really means a lot!
      P.S.: Labs can have a long turnaround time. So don’t get worried if you don’t get the results after a couple of days; nothing is wrong, it just takes the lab some time to process the results.

  67. Hello, I am 5’8 165lb male. I was a heavy dabber and edibles consumer until 50 days ago. I tested positive for THC on my 37th day clean on a 20ng test. I past a 50 ng for a job that following day and also past an at home 50 ng test 2 days after passing for the job. I have to take another 20 ng test in 2 days, which will be 52 days clean and about 16 days after passing the 50ng tests. What are my chances of passing the 20ng test?

    Reply
    • Dear Frogger, thank you for a very good question – the difference between passing a 50 ng/ml and 20 ng/ml. To pass a 50 20 ng/ml test, one should consider the half-life of THC. The only good study conducted in this area says that the half-life of THC in the human body is about 1.3-1.4 days but that was measured with a high THC blood concentrations and doesn’t translate well to low THC blood concentration. In short, we don’t really know because of pharmacokinetic uncertainties.

      However, using a rough estimate, the situation here is quite clear. 16 days after passing the 50 ng/ml drug test is more than enough time for the THC levels in your blood (and hence urine) to drop so much that even the 20 ng/ml drug test won’t detect the THC in urine.
      In any case, be sure to enjoy a high-calorie diet before the test (this will furthermore increase your chances of passing the test). Good luck!

My at home test for 50ng I even took as my first urine of the morning and still passed the line was kinda of faint but a line is still passing.

  69. I am 5’4 female 142 lbs and the last time I vapes thc was about 9 days ago. I regularly vape every night 1 to 3 puffs for sleep. I have a employment drug test in 2 days. I work out vigorously 5 days a week with some weight lifting. I’ve lost 9 lbs in the last few weeks, drank 2 detox drinks (Qcarbo32) and have done hot yoga to sweat a lot. I took at home drug tests and have not passed them yet. I took one this morning and there was a slight red line (which means a negative). The other tests I took days ago all stated a positive result. Two different tests. The first ones were First Check tests that check for 4-7 different drugs even though I only needed marijuana test. The others were At Home drug testa just for marijuana (cheaper) but they give a negative or preliminary (and you have to send to their lab for further testing). I’m giving platelets (2.5 hour process that removes platelets and then returns your blood – in a week my platelets will be back up again) tomorrow morning hoping that will help me pass the drug test in two days. My question is do you think I will pass? Thank you.

    Reply
    • Hello Miss Anxiety, your uneasiness is pretty justified. Smoking 10-20 joints/week with above average THC content will quickly increase the time it takes for your body to flush all the THC out. You have a low BMI and have stopped for 3 weeks; the THC accumulation in your fat cells is not as substantial. However, you will need about 40 days of abstinence to flush all THC out. I would suggest being physically active in the first 30 days, then checking with a home drug test to see if you’re already testing negative, and if not, a small dose of THC detox pills should squeeze the rest of the THC out before the drug test.

  76. I just wanted to follow up and let everyone know that I did pass the 20 ng cutoff drug test 16 days after the 50 ng test which I passed as well (the 50 ng test was taken 37 days clean). I wanna add that I was still dirty on a 20 ng cutoff test which I took which was 36 days after my last time dabbing (the day before passing the 50 ng cutoff). Also I would like to add that within that 16 days between passing the 50 ng cutoff and the 20 ng cutoff that I consumed seval fruit based gummies that contained pectin each day. I would like to know of pectin especially if consumed daily actually helps detox THC from the body? It is my understanding that people use pectin a day or two prior to a drug test to help the THC stay in their stool and not pass through their urine. I’m curious to know if one were to use pectin in their daily diet instead of just as a quick detox will it help decrease the time it takes for THC to leave their body? I have read that you pass more THC through the stool than your urine. It would make since to me that using pectin along with a high fiber diet will decrease the amount of time that THC will be detected in your system.

    Reply
    • Hello Alex, gaining weight and smoking will accumulate THC in layers of new fat cells. However, the accumulated THC from 6 months ago should be gone by now and the recent smoking is not ready chronic enough to warrant some kind of accumulation. As always, you should check with a home drug test to confirm you’re negative.

      Reply
      • Hello Josh, starting a thorough THC detox with Toxin Rid is pretty much the smartest choice you can make. Being a chronic user and having only about 15 days of abstinence is tough; you do need all the help you can get. Along with Toxin Rid which does the majority of hard work by eliminating THC via feces, you should also increase elimination via urine, sweat. That means cardio and plenty of water, coupled with a low-calorie diet.

        Just remember: a day before the test, switch from a low-calorie diet to a high-calorie diet to stop THC stored in your fat tissue from entering the bloodstream and showing in your urine. I wish you all the best.

It’s really hard to say for chronic smokers but somebody with your BMI should be abstinent for at least 40 days to pass. The keto does help but it’s really hard to estimate how much does it help.

  92. I was a heavy smoker about 1 to 2 grams per day for roughly 3months, I have abstained for roughly 45 days. I’m 5’10 and weigh 68 kg, my job is also really active as I walk on average 30,000 steps a day, what is the likelihood of me passing a urine test, many thanks….

  93. Considering trying for the first time. 5’10” male with 23% BMI. I’m assuming less than a week to be clean again? I’m guessing potency of the weed will matter? What is considered high potency that should stay under to be clean again in a week? Does it matter if it’s edibles or smoked?

    • Hello there, you are right – there are several factors that determine roughly how long your body will need to flush out enough weed for you to pass a drug test. The No. 1 factor is how much you smoke; one joint will usually leave your body within 1 week. If, on the other hand, you are a chronic smoker, THC will accumulate in your body fat and it will take longer; maybe even 40 days.
      In the end, all that matters is the amount of THC that gets absorbed in your blood; high potency means more THC, absorption is pretty much similar to edibles and smoking and so on.

      • I am 5 feet tall, 135-140 pound female. I haven’t smoked weed in 35 days and took a lab Urine drug test today. Prior to getting clean for 35 days I smoked a blunt (about 1 gram) everyday for 2 weeks. Prior to smoking for 2 weeks straight I hadn’t smoked weed in about 70 days and was clean. Before my test I drank at least about 60 ounces of Gatorade with a large amounts of creatine powder and took vitamin b12 for color. I should also note a day before my test I bought a walgreens drug test and was testing negative, even though the line was faint it was clearly visible. Do you think I will pass the lab drug test? I have an average metabolism, but am not very active.
        Also, if I pass the initial testing with negative results will they still sent my specimen for confirmatory testing? Correct me if I’m wrong, but I know initially I was being tested for 50ng/ml but if they send it for confirmatory testing can’t I fail if they detect anything more than 15ng/ml. I read something about the cut off standards being different for initial testing and confirmatory testing. Do labs always send specimens for confirmatory testing?

Will my drugtest tomorrow be positive or not? pls pray for me.

          • Hello JC, consuming a lot of fluids is useful; however, the biggest advantage you have is being abstinent for 40 days. With your body constitution, you have an extremely high likelihood of passing the test.

        • Hello Jessica, you only have to worry if you’ve been a heavy chronic smoker (a joint/day or more). In such cases, THC accumulates in the fat tissue and it takes longer (even more than 35 days) for all of the THC and its metabolites to leave the body.

          In your case with only 2 weeks of use, you are quite safe. The negative home test is the best warranty you can get. You are correct in assuming some labs confirm with 15 or 20 ng/ml tests if you test positive on a 50 ng/ml test. Labs only send the specimen fr a confirmation testing if they are positive; which in your case is extremely unlikely.

  98. 5’7 female, 147 lbs and 30 years old.

    Quit 6 days ago and have more than a month before I have to take a drug test (in roughly six weeks). Only issue is I was a chronic user before. Smoked about two-three 1 gram joints daily for years. I’ve been drinking tons of water and plan on doing cardio/Pilates/yoga 4 times a week. Drinking 70 ounces of water daily and taking vitamins. I’m so worried though, since the only weed I ever smoked is potent. I have to take a drug test for my clinical site at a hospital and I have bought drugs tests and I’m obviously still testing positive. Do you think there’s a chance I could fail in mid December if I stopped now? (Late October). Do you have any tips to speed up the process naturally?

    Thanks

    • You have a good chance of passing a 50 ng/ml test; however, the likelihood of passing the test does decrease with increasing test sensitivity. It is entirely possible that you will pass but it doesn’t disqualify the option of not passing.

      Reply
    • The results are rough estimates without any significant measures, such as a light detox, taken. Drinking a lot of water can decrease the time by about 10%. The use of vinegar, as it currently stands, is a myth – there is no available scientific paper that would connect the use of vinegar (or lowering urine pH) to solubility or elimination of THC or it’s main metabolite THC-COOH.

    • Hello Fermin, that’s a great question! Lets first clear up the ‘faint line’. ‘Faint line’ in a majority of cases is a negative result.

      Burning fat tissue does release THC trapped there. However, I’m doubtful that the speed at which it is released is significant enough to show on a drug test. No one has done the experimental work on this one so it’s hard to say.

    Reply
    • Hello Tyler, 3.5 grams/day is quite substantial but the low BMI (body fat) can save you here. Normally, it would take about 40 days for a heavy chronic smoker to pass a drug test. However, with your physique and activity, you will probably be able to pass a drug test even in 30 days. It’s impossible to know for sure; check with a home drug test after 30 days and you’ll see if it’s negative or not.

  119. Sorry for the long post in advance,

    Hi I am a male 5’9 162 pounds. I started vaping dab carts in the beginnings of July up until September 29th, the last day I smoked. I never smoked prior to those months. I would go through about one gram dab cart in two weeks, Sometimes two in two weeks. I would basically be taking many hits from the pen throughout the day, daily, even when I was already high. Sometimes I would go under my bed sheets and use it as a sorry of hotbox (idk if this would make me have more thc stored or not). I went through about 8 1gram dab carts total over the course of 3 months. One point I had two pens and would take hits from both at the same time (I was lowkey hella addicted lmao). There was two occasions when I took like a week break from them because I could find anyone to buy them from. I quit the habit September 29th. I have a drug test in January 2020. I am athletic, Im slim with muscle but with a little Fat around my torso. Probably 15%-19% body fat. I wear 32 waist jeans. I have a kinda big butt for a guy, so idk if thc stores in there too lmfao. Im fairly active, I take the bus to school and work so I’m walking a lot too and I drink lots of water and been eating healthy, even started a Keto diet to try and speed up my detox process. I’ve lost weight over the last couple months went from 175 pounds to 162. I think my metabolism is average, not fast, not slow. I also do running 3-4 times a week for 30 mins to an hour, sometimes 2. Also started taking vitamin b12 daily to try and help. . I’m just wondering if I will be able to pass the drug testing after 100 days since it was dab carts with high potency thc. I’ve read that because thc concentrates is so high in thc % it could take more than 100 days to get clean. This is terrifying. By the drug test comes around I’ll be 108 day a clean. Should that be enough time to pass a urine test, even for a heavy thc concentrate smoker? It doesn’t seem like there’s a lot of sites that put how’ve long it should take for dab cart smokers to pass, it’s usually weed that is talked about. Anyway I don’t have a ton of fat it’s just the amount of 8 gram thc concentrate that I smoked over 3 months that has me worried if I will pass. Is that a super amount? Sorry for long post again, I’m jus freaked out lol I’m never doing dabs again

    Reply
    • The morning urine usually has the highest concentration of THC; if you’ve passed a home test using morning urines that’s a further confirmation you’re in a good shape for a drug test.
      Dabs vs. cannabis is an interesting question. It boils down purely on how much THC has entered your bloodstream. From there on drug kinetics (distribution, metabolism, elimination) is identical for dabs and cannabis. How much THC has entered the bloodstream again depends on THC-content, quantity, absorption coefficient and so on.

        • Hello Anthony, you have a big advantage with such as low BMI and low body fat percentage. Chronic male smokers are looking at around 40 or so days in order for all of the THC to leave the body. With your body composition, you have a chance to be THC test ready in 30 or so days. But this is just a rough estimate; estimates are the hardest for chronic users. Do pick up some home drug tests at your local pharmacy and test yourself after 30 days to see if you’re clean.

          Reply
        • While it can be true that a blood drug test can detect THC in your bloodstream only 3-4 hours after ingestion, you should not count on it. With blood test, the sensitivity of the test used is of paramount importance. The low sensitivity test will detect THC only hours after ingestion but the highest sensitivity one can detect it for months. So, it’s incredibly difficult to say for your if we don’t know what kind of test they will run.
          The FBC test is usually not looking for drugs; its purpose is to detect medical condition such as anemia or infections. If this is the blood test you’re likely to face, you don’t have to worry – they are looking for your wellbeing, not drugs.

  121. Hello. Thanks for all the info. I hadn’t smoked or dabbed for over 4 months and just the other day I took 5 dabs throughout a night. Its my understanding that 1 dab is equal to about 10mg after combustion so 5 should be equal to about 1 joint. I may have to do a urine test later this week which would be 7 days after the dabs. I been drinking a lot of water each day as well as eating salads, drinking citrus teas high in vitamin c as well as other B vitamins, drinking green juices such as spinach and kale juices, eating salads each day, and eating gummies made from natural fruit pectin. I’ve even drank a sports drink mixed with sure jell and plan to drink another sure jell sports drink mix the night before the test. I am also very active at work. What are the chances of providing a clean urine sample within 7 days after 1 time use?

  122. Hi, i am a 5”3, 108 lb female , and i am a chronic user. I have been using thc concentrates 1-2 times daily for the last month, and before that i was smoking about 1/4-1/2g of high thc content (20% ) flower daily a few times a week, since june 2019 ( with the exception of periods of 4-12 days where i went off of marijuana for a tolerance break). I have built up a fairly high tolerance to bud as well as concentrates and edibles, but i have a very high metabolism. The last time i smoked was today. If i abstain from smoking/using any form of thc, exercise daily and drink plenty of fluids, how long would it take me to pass a normal urinary home test hit?

    Reply
    • Hello Shannon, thank you for a very extensive insight. You are increasing the THC elimination in a number of ways, all of them are helping you improve the chances of passing. The best information is that despite being a chronic user, you have lost 9 lbs in the last two weeks. This has forced THC, accumulated in your fat cells, into the bloodstream and significantly increased THC elimination. I have to say I am unaware of the platelets procedure and its effect of passing a drug test; an interesting and thorough approach.

      With such varied factors, it’s hard to say and it’s best to trust the home drug tests. If they are negative, there is a strong chance you will pass. However, do enjoy a high calorie-diet before the test to stop the remaining THC to be eliminated via the urine. Hope this helps.

    • Hello Will, for the past 3 years your body has been storing THC continuously in your fat tissue. The bad news is that it will really be hard to get it all out; it definitely won’t be quick. For long-time chronic smokers, it can take from 30 to 60 days. Some people tested positive even after the 60th day. The best strategy is to get a bunch of at-home drug tests and test yourself every 10 days or so. Those tests are pretty accurate and you’ll have a clear indicator when you’re clean (or at least clean enough to pass a drug test). Hope this helps.

I do workout intensely every other day. 20 days ago I took 4 blinkers (15 second hits) of a 92% thc distillate cartridge.

I’m very paranoid and my anxiety is killing me.

    Reply
    • Dear Jacob, you don’t have to worry one bit. The old THC is out already; the only thing to consider is the THC from the 4 blinkers. Given your body constitution and activity levels, you’re almost certainly already passing a urine drug test. Check it at-home drug test, just to be sure and to lower your anxiety levels. In any case, in early June, you will pass a drug test. Just don’t let the anxiety get the better of you. The only way you can fail is to light a joint to deal with the anxiety.

I smoked a dab pen everyday for a year (a few times a day) and then stopped in August and then smoked for about a week in the end of December. Then took an 20 mg edible in January and total of 40 mg of edibles around Feb 22-25. I have been clean since but will have a drug test within the upcoming days. How likely is it that I am clean now?

      • Dear Jacky, it’s absurdly likely you will pass a drug test. The edibles were 2 months ago, your body constitution is on the small side and despite you being inactive, you’ve probably eliminated all the THC in your body. To alleviate anxiety a bit, spend a few bucks on an at-home drug test at a local pharmacy. It can ease your mind even further.

    • Hello Jared, if you’ve been using marijuana for a long time, the THC would accumulate in your fat tissue. One great thing is that you don’t have that much fat tissue. Nonetheless, chronic smokers start to test negative after the 30th day. It usually takes between 30 and 60 days. Given the high activity and metabolism rate and low body fat percentage, you’re most likely to start seeing a negative result after 30-40 days. Hope this helps.

    • Hello Violet, you have nothing to worry about. In 60 days only the heaviest chronic users have issued with passing a urine drug test. With your body constitution, you would probably need only about 10 days to flush all the THC out. After 75 days, you will pass the drug test with the utmost certainty.

  132. I am a 5’8” 200 pound male who uses gravity bongs (GB’s) as my main form to smoke. I am a chronic user who usually takes 2-4 rips 2 to 3 times a day. Could potentially be interviewed for a gov job in a month or two so am worried how long thc/tree stays in my system. I want to go ahead and apply but dont want the interview to be too soon.

    • Hello Jordan, getting the job in your case could be a double-edged sword. Given your body constitution and chronic smoking, you could test positive after 40 or even 50th day without using the gravity bong. The most natural way to detox quicker is to get a complete THC detox program and follow it; cardio, sauna and enjoying a low-calorie diet helps a bit as well.

  133. I should also add that my metabolism is average but get physical activity once every 3 days. Trying to increase physical activity to burn away the thc. I had smoked 2 rips this morning and went on a 3 mile run drinking lots of water. Trying to run 3 miles everyday for physical activity. Is there more i can do besides buying detox? But again my main question is how long will it take thc to leave my body.

  134. Hi, I’m 5’8 244 lbs male. I have been smoking on and off for 4 yrs, about 0.3-0.5 grams a day. I took a t-break from dec to feb. I started smoking again mid feb until the end of march. I have been clean since then (28 days) and by the time I take the test in June, I will be clean for 80 days. You think i will be ok to pass a pre-employment urine lab test? Thank you for your help.

    • Hello Heather, the estimations of how long it will take are the hardest in the case of chronic users. It can take between 30 and 60 days, however, it’s almost impossible to figure it out theoretically. Do check with at home drug test from time to time to see if you’re negative.

  135. Thank you for your reply! just wanted to update ya i took a home drug test and failed:(
    U think 80 days is suffice given my chronic history of smoking 0.3-0.5 gm of mid-high grade almost everyday? Im just really anxious

    • Hello Silas, for a chronic smoker, it is completely natural to fail a drug test 28 days without smoking. You might even test positive on your 50th day. However, on the 80th day, the chances of failing a drug test are completely insignificant.

  136. I’m 5’3″ 200lb and sedentary. I used to be active but an injury put me through a long recovery and I gained weight. I was a chronic user (~1g/week vape pens) for 3 years and stopped on new years eve. I have a job offer and wanted to know if I would pass the drug test. I believe it’s the kind where you pee in a cup and they send it to a lab.

    • Hello Brittney, sorry to hear about the injury. The good news is that you don’t have to worry about failing a drug test. By now, you haven’t ingested THC for more than 4 months; that should be more than enough time for all the THC to leave your system. Check with at home drug test; it will put your mind at ease.

  138. Hello!

    I’ve been a daily user (some days off, but generally speaking 5 – 6 grams a week) for a year, mid/high grade.

    I’m male, 185 lb (84 kg) / 1.67 m (5ft 4in) and 24 years old

    I believe I’ll be having a DT on july 1st — in 56 days.

    Considering I do small amounts of exercise (15-40 minutes 3 times a week) and have just been drinking water and minimal amounts of junk food as well, are my chances good?

    Really nervous as this will be my dream job.

    • Hello Axel, it difficult to estimate how long will it take for a daily user. THC has been accumulating in your fat tissue for a long time; it does take longer to all be flushed out. However, 56 days is quite a long time and you will most probably be OK with just the basic exercise and drinking water. Nonetheless, get yourself some at home drug tests from your local pharmacy and check yourself 30, 20, 10 days before a drug test. It will put your mind at ease; it’s important to have a plan in mind, especially with a dream job on the line.

  139. I am not a heavy smoker at all. I took one puff from a home made bong last Monday and I have a drug test tomorrow. I’m still kind of paranoid it might still be in my system. Im 5’6 230lbs female. What do you think?

    • Hello Debby, that one bong hit is not significant enough to be picked up by a drug test. It really all depends on how frequently you ingested THC before that, hope everything goes well.

  140. I’m likely to have a test in 3-4 weeks. I stopped smoking ~1-1.5 bowls/night 5 days ago. I run 5-10 miles/week, am 5’11” 175. How at risk am I? I smoked at that rate for about the last year.

    • Hello there, not everybody can pass a drug test within about a month. Nonetheless, high physical activity can help a bit; keep doing that. It’s just really hard to say if that will be enough or not.

  141. Hi, I’m 5’4, 116lbs, female and recently started to smoke about 3 or 4 light hits of a blunt a couple days a week. I have a drug test coming up in about a week, is there any chance of me passing?

    • Hello Vanessa, you’re probably looking at a 50:50 situation. In a week, some people with your smoking frequency do pass a drug test. Nonetheless, some don’t. Hope everything goes well for you.
