How Long Does Marijuana Stay In Your System?

in How to Pass a Drug Test

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 have not smoked pot in over a year because I am probation. I get piss tested every 25 days and my color has come up today. Some friends want to get stoned this weekend and I want to know if I will piss clean in 25 days.
I don’t really exercise much and I’m 5’7 200 lbs. Probation is over in about 6 months and pot is not worth getting it extended for so I would only smoke if its a 100% guarantee that I will piss clean in 25 days.

So what do yall think?

is there anyway you can COMPLETELY FAIL a drug test and then COMPLETELY PASS the very next day..???

Reply

Dee February 16, 2010

Yes, it’s possible to pass a drug test one day and then fail it on another day. For two reasons: it’s rare, but sometimes a test WILL give a false positive or negative. The other way it could happen is if you haven’t smoked for a long time and you’re right on the border of being clean. You might happen to drink more fluids one day without even thinking about it, which could be enough to dilute you just enough to test negative even though you’re not quite clean yet.

As long as you didn’t smoke yourself, you’ll pass with no problem. The second-hand smoke thing is a myth, unless you’re in a closed up car for hours with a few heavy-duty stoners. No worries. :-)

haha if you didn’t hit it then you have nothing to worry about. thc can not get in ur system unless u actually smoked or eat it. idk y ppl say u can get second hand high but unless ur family was hot boxin with u in it there’s no way. even if u did smoke, since u r not a pot head, u’d be clean within 3 days.
i’ve smoked since i was 9 everyday at least 3 times a day and it took me 2 weeks to get clean and now i only smoke once a month and kno im clean after 2 days…actually i jus took a test today and smoked last night… i always drink a half gallon of green tea and water sometimes i take some water pills jus to be sure…but im sure ill pass i use to be on ua’s and thats what i use 2 do and never ended up bak in the pen…thank god

It’s impossible to say for sure, there are too many factors involved. Best guess is somewhere between 3-6 weeks to pass a urine test naturally. Only way to know for sure is to just start testing yourself at home every week or so.

If u guys wanna pass a drug test then all u need is bleach. Get a dropper and put about 8 drops in a big cups of kool aid and jug it after that drink alot alot of water. Stupid but if u really wanna pass it as I wanted to u’ll do it

Reply

dish January 22, 2010

Ummmm…. NEVER EVER EVER EVER EVER EVER EVER EVERRRRR drink beach!!!! how stupid can one person actually be??? I am an ER/TRAUMA nurse and i would NEVER encourage someone to drink bleach!!! besides, if you had any brain cells at all you would think about it a little… since when do your fat cells (where THC is stored in your system) just magically dissolve and rid of themselves through your kidneys??? if that were true why in the HELL would it be so hard to lose weight??? the TCH is stored in your fat cells and without increasing your metabolism to burn some fat cells, and THEN trying to flush the biproducts of the burned fat cells out with WATER (NOT BLEACH) you will not be able to rid of the THC in such proclaimed rapid times. furthermore, the only thing bleach is good for is DISENFECTING and WHITENING… what the HELL makes you think it rids your fat cells of THC… its LETHAL to ingest…use your brains people…

Reply

Anonymous February 10, 2010

But wouldnt the bleach get into your piss though and throw off the tests. I know that it wouldnt clean your system but if it could highjack the test then it would work right? 8 drops isnt much anyway… I used a cap in half a gallon (dangerous) to get into the military and I was a heavy smoker til the last week before i left. Not promoting this method but the logic seems resonable to me

Dee January 13, 2010

Tonya, if your brother was completely clean when he took those 5 hits then he will definitely be clean in a week. If you don’t smoke often, or a lot, it only takes 2-3 days to get clean. Tell your bro to limit himself to once a week AT THE MOST, then his thc levels won’t build up and he’ll always be able to get clean in a hurry.

dont trip fool one hit doesnt even process into you system that shit will go right through your body a drug test needs a certain amount of thc metabolites to have a positive result.. if ur on probation or some shit and get tested like once a week you can pretty much smoke a lol snap to your dome the night after you test every week.. just make sure you get a lil excersize everyday and your cool.
