How long does marijuana stay in your system is a popular topic, that’s for damn sure. And you can find a TON of regurgitated facts and figures on the Internet about it that all say basically the same thing: “it depends on your weight, your body fat, your metabolism…” YADA YADA YADA.
But since it’s a pretty good bet that you’re asking because you’re a pot smoker who’s got a test coming up, maybe what you should really be asking is: “Do I need to be worried about whether or not I can pass a drug test?” Because the thing is, if you can HIDE the fact that you smoke pot, then you don’t even need to worry about how long does weed stay in your system.
The TRUTH About How Long Weed Stays In Your System
If you’re someone who only smokes a little pot every once in a while — I’m talking like a couple of hits once or twice a month — then your body will be clean within a few days to a week after your last smoke, tops. That’s true for both urine and saliva drug tests. And NO, you aren’t going to fail your drug test just because someone you hang out with gets high. That’s just a big fat myth invented by some paranoid non-stoners.
But if you smoke regularly — a couple of times a week or more — then the length of time that weed stays in your system gets a lot more complicated. It doesn’t matter if you only smoke a couple of hits at a time, or a couple of bowls, it’s the regularity of your smoking that’s the problem. You end up with a backlog of THC metabolites in your system. And the longer you’ve been smoking weed, the longer it can take to get clean.
If you’ve been a heavy smoker, you shouldn’t trust ANY charts you find on the Internet about long it takes for marijuana to get out of your system. The plain fact is that we’re all just too damn different, so I don’t care how long you look, you’re not going to find any secret formula to answer your question.
If you have a low body weight and a fast metabolism that can help, sure. But trust me, that is not a guarantee that you’re going to be clean in 3-4 weeks. Over the past several years that I’ve been helping people pass drug tests, I’ve met way too many smokers who just didn’t fit into any kind of neat little prediction model.
If you’re going to be taking a urine test, then the best advice I can give you is to TEST YOURSELF if you want to know for sure whether or not weed is still in your system. You can get some cheap home test strips here, and always test your first pee of the day. That one always has the highest concentration of THC metabolites, so if you can pass that test, then you can be confident that you’ll pass when it really counts.
And if you need to pass a saliva test, consider yourself very lucky. You’ll be clean within a few days after your last smoke. Click here if you need to know how to pass a saliva test in 24 hours or less.
Is There Anything You Can Do To Get Weed Out Of Your System In A Hurry?
I’m going to be blunt with you: there is so much ignorant information floating around out there about how to get weed out of your system that it makes me crazy. And I’m sure it makes you crazy too, because you’re probably desperate to pass a drug test and then you have to sift through a mountain of shit to find some decent answers.
Here’s the bottom line… If you’re going to be given a urine test, and you have the luxury of several weeks notice before your drug test, then go ahead and exercise and try to lose weight, etc. etc. But if your test is in the next week or two, don’t even bother. Heavy smokers would need to lose a dramatic amount of fat almost overnight to pass a urine drug test that’s right around the corner, and obviously that’s not going to happen.
Instead, the question you need to be asking yourself is “How can I pass a drug test?” I guarantee it’s a lot easier than you think, and once you’ve got a handle on it then your troubles are over – period.
Here’s an example:
Smoker #1 gets high several times a day – every day – and he has for years. But he knows exactly what he needs to do to get a false negative on a drug test, whether it’s a urine test or a saliva test. So, not only is he able to pass any drug test that gets thrown his way, he also never loses any sleep worrying about how long marijuana stays in your system. To him, it just doesn’t matter.
Smoker #2 just shares a bowl with one of his buddies once or twice a month. But he has NO clue how to pass a drug test, and he wouldn’t know how to get on the Internet if it sneaked up and nipped him on the butt. So if he happens to get tested the following week after one of his weekend get-togethers, there’s a real good chance that this poor guy will fail – even though he hardly ever gets high.
So the real key to this issue isn’t so much knowing how long marijuana stays in your system – it’s knowing how to make it LOOK like it isn’t in your system. Once you know how to do that, then you can stop being paranoid about whether or not you can pass a drug test. I know that feeling, and it totally sucks.
The plain fact is that you aren’t going to find anything on the Internet that will give you definite information about whether or not pot will still be in your system when you show up for your test.
But hey, wouldn’t it be GREAT if there was somebody who could tell you, “okay, according to our calculations you won’t have any THC in your system after next Tuesday at 4 o’clock”? Sorry, but down here on Earth, that just ain’t gonna happen.
Fortunately, passing a drug test isn’t that hard. At least, not once you wade through all the sales hype out there written by companies who want you to buy their useless, expensive detox products. People DO successfully pass drug tests, every day, and they never lose any sleep worrying about how long does weed stay in your system.

I’ve passed tests before, usually try to buy myself about two weeks. Moderate to high workout everyday (or every other day), teas, LOTS of water, vitamins everyday (lots of B), sauna, low cal foods (no sugars/salts)… and yeah. 1/3 Gatoraid and 2/3 water is also a good intake for liquids in attention.
I have another test coming up for AT&T in a week or two, and I just cut myself off from heavy smoking on Sunday. I’ll let you all know how this one works out.
i would venture to say, if the drug test cut off is 50 ng/ml you have a good chance it won’t show up at all. HOWEVER, this is dependent upon the size of the hits, potency of the product and how long you inhaled for… if you drink some water and don’t void first thing in the morning you’ve got a good chance of passing imo (ASSUMING the cut off is 50 ng/ml and you really only inhale 2 puffs every few weeks or so)
Just for other people’s info, this is my experience. I started out completely clean of thc metabolites in my urine. I took 3-4 small hits of old marijuana and tested negative on QuickScreen with a faint line the next day. 3 days later (today) with a morning void and i passed a First Check home test with a dark line.
my point is: it IS possible to smoke so little that you never go over the 50ng/ml. and if you don’t go over 50 ng/ml with a one-off smoke, it can clear out rapidly within 3-4 days. hope this helps anyone in a similar situation. good luck.
ok so i only really smoke weed occasionally. Went to a festival on the 28th august and smoked some that day and the 29th. Wasnt a lot really. Getting a new job they are going to ring me on wednesday and im going to have to go in for a drug test. how long does anyone rekon it will be in my system for.
i smoked 3 days fully and i took a quick hit last night which wasa dumb but it happnened i have a drug test in a month do you think i’m ok if i drink a lot of water and a dextox tea a few times?
smoking 3 days fully doesn’t tell how much you actually smoked or the potency of the stuff. it really depends on that. there’s no black or white in this situation. it all depends on how high the level in your blood got…
Just a tip, if you are trying to drink a ton of water to dilute, it’s not as difficult if you are thirsty, so keep eating spicy food to make you thirsty.
I have smoked twice in my life, the last time i smoked was 45 days ago and i have a test in 3 days. do you think ill pass?
p.s.: The test has a cutoff of 15ng
if you’re telling the truth and you’re not some freak of nature metabolism wise, yes i’m almost 100% positive you’ll pass. even if you smoked quite a bit that one day.
I have smoked twice in my life, the last time i smoked was 45 days ago and i have a test in 3 days. do you think ill pass?

LOL yea you should be fine are they doing a GCMS test? they must be if the cut off limit is 15 NG that really low usally they all check for 50 NG usally if you take a test they run it in Immuassy test(50ng) if you fail that then they will run it thru the detailed test wich is the GCMS (15ng) they run that test just to be sure you really have drugs in your system but if you pass the first one then they will not run it again GCMS test cost many thousands to run
I get tested weekly. I smoke right after my test, Mon afternoon until Wed night. Then I stop, drink at least 10 cups of water/tea a day, and exercise for about an hour every other day. My diet consists of fruits, vegetables, and protein. I avoid greasy foods, DON’T EXCEED MY CALORIE INTAKE, and steer clear of breads and sweets. Also I only drink water or tea. When Monday comes around I’m clean.
Dude, is it really worth smoking pot for that kind of diet?
I use3d to administer drug tests folks!Beleive it or not detection time is approximatly 14-16 days for the average person,PERIOD………Now if you are 40 or more lbs. overweight then you have a problem!!The people giving the drug tests would prefer you didn’t know this but FAHQEM,I am sharing my knowledge of this………..14-16 days,and don’t waste you hard earned money on bullshit detox fixes,they DO NOT work or they are tested for.The only 2 ways in not smoke or get you someone else’s piss!!!!
> detection time is approximatly 14-16 days for the average person,PERIOD
I have to seriously disagree with this statement. That’s true for SOME people, but you’re really messing with people’s lives by implying that it’s true for most people.
You may (or may not) have administered drug tests in the past, but I’ve been helping people to pass them for the past 3+ years. If you used to work in a drug testing clinic then you should know that people’s smoking habits and metabolisms are too different to even be able to say that there is an ‘average’ person.
I’ve met a surprising number of normal weight folks who were still testing positive after almost two months, just because their thc levels were so high to begin with. And I’ve also known a couple of significantly overweight people who didn’t have nearly that much trouble getting clean. Go figure.
You’re absolutely right that detox fixes are either tested for, or just plain don’t work. But don’t say that the only way to pass is either to quit or substitute. Because if someone diluted correctly so that their specific gravity and creatinine levels looked normal, you wouldn’t have known, now would you? ;-)
How do you properly dilute yourself?
not to mention it depends on the cut off level, potency of the stuff, lung capacity, etc etc etc…. i don’t mind when people have erroneous opinions, but it’s really a shame when they give credentials as if they actually know what they’re talking about and they’re completely wrong….
depnds how often a user u are
I’m about 170 pounds i took about 3-4 hits of a joint around july 2010, and took a piss test on august 25th 2010, i skate, excercise, will i be straight?
Do any of you know what drugs they test you for in a “sports” drug test.
mostly they test for steroids and urine coverups
nah, they test for more then that… Depending on what level of sports you play. their gonna test for just about everything… I know in college they have a lot of money and that means they can afford to test you for all the bs out there
I smoked a blunt for the first time in my life yesterday and just found out i have to take a urine and blood test in 3 weeks. Do you think I’ll pass.
You have NOTHING to worry about, trust me. Just don’t smoke again between now and then.
Hi ,so i dont have a specific test on a specific date,however i just got a phone call saying i may be summonsed to court over my little sisters custody battle. Of course i want to help her. I decided to stop smoking on the 8th of august b4 i learned of the custudy issues,and today is the 20th.Like i said still no specific date. I weigh 138,i am a very active person,eat only healthy foods,no junk what so ever. All i drink is water,it has been that way for years now. I do have the occasional beer,n drunken state. I jog at least 4 times a week,And im 5’4″..i smoked everyday for ,who knows how many years..My question is,what would my chances be if i got drug tested next week,or so on.I know my chances of passin gets greater the longer i dont smoke,and i have no intentions to smoke. I just dont want to screw her life up,or her childs. I appreciate all the help,thanks a bunch…Peace,hippyfairy…
Ok….I smoked this Sunday like 2 or 3 hits off a joint I am 5’1 and weigh about 115lbs and have a pretty high metabolism….I have to take a Piss Test tomorrow around noon. I work out regularly, took Niacin today and have been drinking water like it’s going out of style. I also don’t smoke that often….do you think I’ll be ok?
so heres what happened i smoked a joint and a bowl on aug 15th and a bowl on aug 8 i really havent been smoking heavily before aug 8th maybe a eigth between july 1st and july 23rd. im 5’11″ and weigh 147lbs and i know i have a fast metabolism. I have a piss test aug 24th. Do you guys think i could pass my piss test if i drink bunch of water and a lot of beer fri/sat and sweat a lot. Please respond im nervous as hell because im on parole
Dude quit smokin lol jesus but prolly not I doubt you pass srry dude it took me 3 months to be clean!! I quit on june 3 and failed a test on Aug 25! but then I smoked about a QP a week you know it just depends on really how good the weed was.
if we knew if your gonna pass or not we wouldnt be on here looking for answers ourselves so why doesnt anyone just give the facts and stop with the questions
Because there is no way to really tell if ur clean there are no facts really to give. now I smoked kush every day all day, then in June 3 I quit on August 25 I took a piss test and still failed if you smoke ALOT it can take upto 3 mounths to be clean I am 5’5″ and 135 lbs and it took 3 mnt for me to detox if you are really worried about go buy the fake piss works like a charm. I smoked about a QP a week I grew it lol but those days are behind me :()
why does everyone ask if you think they will pass when everyone on here is looking for the same answer
So, i had to do the hair test for drugs, and don’t smoke not even occasionally, other than back in may i took just a hit off a 1 hitter, but drink alot of water, sweat alot, and relatively high metabolism (if that really matters) will that much affect me when it comes to the hair test?
Exactly what I was thinking. Probably not, cuz no other posts. Mandy never reposted either. Must be in the grey bar inn.
why cant anyone just tell us facts of their screens instead of asking if we think they will pass
I have passed one in as little as 9days off, Smoked daily, yet im still worried about one i have coming up,I haven’t even smoked but twice this month and it’s already been 6 days since, I drink water and excercise, I’m 5’6 140lbs, I already have the job, just haven’t been tested yet.
You guys think if I passed on the 9th day clean b4 I can do it again?
I think Yes(but will still be nervous,its a good job)
If its been 2 weeks and your skinny, you will pass if you hydrate daily, especially test day if you know it. Water + Vitamin B to color your pee.
Just learned about the creatine level test, I have creatine, should i take it?
I’m not a regular smoker anymore. Although, about 3 yrs back I was and a heavy one at that. I had been consistently smoking for months up until a monday when I received a phone call to come in for an interview, by that wednesday I was up for a test. I drank lots and lots of water plus a few ounces of vinegar every few hrs, as well as went running til I was dripping sweat. I passed my drug test then and now I’m hoping I can again. I’m in the same shape I was in then, about 135 lbs 6’0 tall, 23 yrs old now. Keeping my fingers crossed and trying it again! I wonder if that was just a one time fluke? What do ya think?
well i know its late for me to reply, but in case of future “mess-up” this is what i do, im 16 years old atm and my parents force me to take drug tests at end of month, and i simply ask my little sister to piss in a zip loc baggy, tape it to my thigh and put a hand warmer in my pocket and just play with it keep the piss warm and u will pass the drug test…
I’m 5’5 & weigh 140 . I used to smoke 4-5 bowls a day . The last time i did was on 7-9-10 , & i had to take a drug test for a job on 8-13-10 . Do you think i passed ?
lol
That’s all I do. I drink only water, OK and organic dandelion and chamomile teas. I also eat fresh fruit and veggies. I am a health nut so I always eat good. No fast food, fried foods,breads,pasta,sugars or sodas. I wonder if I can pass this piss test this coming week?
I have a job interview coming up. I smoke weed everyday all day. My last J was last night. My interview is sometime this week. I am 165lbs and at the gym about 5 days a week. All I drink is water never any sugar and no bread,pasta or anything that can hurt my chances. Also is there a way to know if my fast metabolism will help clean this out?
DAT SUXX(:
I gotta drug test on seb.21st I’ve been clean for
Like about a week but before that I was straight smoking
Kush everyday u think ill b clean by than
If I drink plenty of water???
no
ya howd it go
I had to take a drug test for work. If it looks clear does that mean Im clear? did not drink a lot of water before. I quit smoking june 1st had a few hits end of july took my test august 12th. What are my chances wont pass?
You’ll Be Fine.
Probably really trashy judging by her posts.
Funny thing is, the people on here that do smoke have way better grammar than you so maybe you SHOULD smoke!
I smoked a blunt three weeks ago, will i be ready for a test in 2 days
depnds how often a user u are
how much will it take the marijuana to leave my system if i took 20 hits
If i took 20 hits and i am 5’5 and 120 pounds, how long do you think it will take for it to leave my system.
One hit is the same as 20. Anyway who counts their hits?
wrong
wrong, and right. it does depend on how much you smoke
Ok due to all the dicks saying don’t smoke weed stop it just didn’t help these people are freaking out and just want a word of advice not another parent on their ass but sorry I have no advice I’m in the same situation
I smoked from a bong twice in one night on sunday, i have a test on the 23. ive never smoked before thatam , i gonna pass the test?
6′ 240lbs muscular, normal metabolism, first time smoking in a year smoked 3 bowls with my wife ten days ago, piss test today. Was on vacation drank plenty of water and alcohol but did not flush system or do anything special, got a little bit of exercise. Clean or not?
UGHHH! Everyone get’s on here, explains their situation and when they are going to have a drug test, then finishes with “do you think I will pass?”. Well we’re not getting anywhere with this! People need to start coming back on here AFTER the drug test and letting the rest of us know whether they passed or failed! This would be very helpful!
Well I kant give much advice or better yet much hope for those freaking out. Its happenned to me 2 they kalled me for a urine test on a Friday I had to take it a Monday that Friday night I smoked my usual shared, next day I was freakn outfinding methods to get thc off my body anyways, hat I kan reccomend u guys is to drink a shitload of water 1 day before also buy some orange juice and drink it all , your urine should be nothing but water. I took my test wheter I passd or not I’m not sure since evrybody in that company were drunkies and junkies they probably didn’t give a shit,,, just don’t lose sleep cuz of this, if you passit you passit, and if you fail it then you fail it, its not the end of the world
Yeah well for some of us it is the end of the world. Im a 24 yr old female and i smoked (only took a couple hits) like 2 days ago……i normally dont smoke though and its major jail time for me….i will go to jail until the end of my sentence which could be years!!! the internet says a lot of things about drinking water and what not but now im freaking out… i cant afford to go back to jail when i have so much to wrap up around here. it was a stupid mistake i did when i was drinking and i totally regret it. but i have to take a UA for court……so i dont know how the test works at all….. You can never find reliable info on the net so im clueless as to what to do….i bought that detox stuff but i dont want that showing up on it either. Kinda feel helpless right now.
oh and ill come back if i pass but if i dont leave a reply its because i went to jail…did not pass go and did not collect 200 dollars…
you must be a straight thug gettin drug tested by mommy
yeah man if steph wanted your numba she woulda asked :P
this one time i took a drug test and i didnt drink water just soda and my piss stunk like skunk piss, i reeked up the whole office, i bet they had a good time conducting the test, oh yea i passed btw and got fired my first day of work awesome, you probably wanna grow up to be just like me
so i am an extremely heavy smoker for years. Its been two years since i last got clean and i smoke high grade buds multiple times a day. i have stopped now for 3o days exactly and am still failing. Any idea as to how long this will take. im male 5’7″ 140 lbs, highly active. I dont understand why im still failing.
Anyone have an answer for my previous post?
hey paranoidone, dont worry about it past 90 days you should be more then fine, i was heavy user and stopped. DO STOP work out and lead a normal life, exersise, water, fruit u know normal. I took my drug test 90 days later and i passed
i have a piss test in 7 days but im also 7months prgegnant on top of it can i still pass the drug test even though i smoked yesterday.
If you only smoked that ONE time but hadn’t smoked for a month or two before that, then yeah, you’ll probably pass. But if you’ve been smoking several times a week, you’re probably screwed. If you’re that far along in your pregnancy, diluting would definitely not be a good idea for you.
get some1 2 piss in a cup 4 u thats clean of corse. put the piss in a condom. keep the condom on your belt ban. have a needle in your pants in easy use. unzip your zipper only and poke hole in condom. and keep the piss worm. works everytime.
Potheads, concerned that they won’t pass thier UA so they get on this sight. Then when it is all said and done they never come back here to give thier follow up. Someone said “you sound like you know what you aretalking about” and they were refering to a stoner..OXYMORON????
LOL, just kidding. I am gonna mix it up a little, okay.
Some facts:
Goverment hype says alot of lying crap
“Sperm count goes to hell”
Fact: normal is 100 million per milliliter and it goes to 75 million.
“Causes cancer”
Fact: Anytime you inhale any burnt product, including candles or
inccents, you take that chance.
“Kills”
Fact: Not 1 proven death caused by the effects of marijuana.
Exceptions would be…1 ton bail falls on man, man shot for not
paying for stuff, etc……
1 bad fact is:
Your saliva is your first defense against tooth decay.
Marijuana drys the mouth, you get the munchies, lazy so you don’t wanna brush right after eating. MARIJUANA CAUSES TOOTH DECAY.
Okay, now we can go back to the subject of WATER. No, wait, I mean passing UAs lol
I talk to a lot of people, and I’ve never once heard someone say that it took them a full 90 days to get clean, let alone more than 90 days. But yeah, it could take a good couple of months. Not all heavy users need that much time, but some do, and unfortunately you just might be one of them.
Since it’s been 5 weeks already, I’d start testing myself once a week at this point. Test your first piss of the day, because that’s always the most concentrated. When you can pass that one, then you’ll know for absolute certain you’re clean.
Good luck!
I smoked weed heavy for about 7-8 years. few days off here and there but for the most part i was never clean. I quit 2 months ago (and i feel great now btw) and took a drug test last week and failed. So obviously for heavy smokers it can take a lot longer than 30 days to be clean. someone told me it could even take up to a year. fml
i got into RN school and they are making me piss before i start classes, not just clinicals, they wont do it at the school u have to go to a lab
jesus has a middle name??? haha jus kiddin
yeah, it’s “Harold”
