How to Pass a Drug Test for Marijuana – All About Dilution

in Urine Drug Tests

How to pass a drug test for marijuana is much simpler than you might realize. Probably the biggest problem you’re faced with is just figuring out what you can believe, because most of the information you’ll find on the Internet about how to pass a drug test, for marijuana anyway, is either outdated or downright wrong.

Myths About How to Pass a Drug Test for Marijuana

There are lots of popular home remedies passed around by very well meaning, but also very misinformed, pot heads. Including cranberry juice, Certo (also known as Sure-Jell), and niacin. You can find some facts about home remedies here.

One of the most prevalent myths about passing a drug test is that you should drink tons of water for days or weeks before your test. The roots of this particular myth are actually grounded in reality (as most myths are), but the real facts about it have become distorted over time.

Possibly the biggest misconception about passing a urine test for marijuana is that you can get rid of THC metabolites by ‘detoxing’ your body – in other words, completely cleansing your body and getting back to square one. This misconception is constantly perpetuated by companies who want you to buy their detox products.

But in fact, because THC metabolites store themselves in your fat cells, the only genuine detoxification you could do would be to somehow lose a lot of weight (and fat) in a big hurry. Needless to say, not a very realistic plan. But if you’re in the position of needing to know how to pass a drug test for marijuana, don’t be discouraged by these facts!

How to Pass a Drug Test for Marijuana – What Does Work?

Hands down, plain old dilution is the MOST effective method for how to pass a drug test for marijuana. But the big problem with it is that most smokers don’t understand exactly how to do it, and more importantly they don’t know how to hide it from the drug testing labs.

Dilution does NOT mean drinking lots of water daily for a long period of time, and it also doesn’t mean adding water to your urine sample during your drug test. For passing a urine test, dilution means drinking enough water in a very short time span to overload your kidneys with fluids. When this happens, your kidneys are temporarily unable to filter the toxins in your body (including THC metabolites).

To put it another way, your urine becomes so diluted  by all the fluids you drank that the metabolite levels are too low to even measure, and voila – you test negative. But this also means that your urine won’t contain any of the elements that it’s supposed to have (including color!), which is the big red flag to testing labs that you’ve deliberately diluted and are trying to beat your drug test. Any serious discussion about how to pass a drug test for marijuana, by using dilution, isn’t complete without information about how to get around this problem.

How to Pass a Drug Test for Marijuana and Get On With Your Life

In order to pass a urine drug test for marijuana, you need to be aware that testing negative is only half the battle – you also need to pass the ‘tampering test.’ There can be NO evidence that you deliberately tried to dilute your urine, or you could fail your drug test on the spot. But fortunately for you (and unfortunately for testing labs), there are some amazingly simple ways to hide dilution. I’ve done it myself many times now, and I’ve passed every single time.

How to pass a drug test for marijuana is serious business, but that doesn’t mean it’s a reason to panic. Go here to find out more about how to pass a drug test using dilution.

I’ve past quite a few this way. Just be sure that youve watered down your pee by drinking water all the way up to the test.

i’m 6’1”, 34 years old, 170-175 lbs, smoke daily, & have been since freshman year college (1997). i play soccer 3x’s a week and have been for over 10 years and run on occasion; pretty good shape overall. probably a little fat, but really not too much. i just got a new job. i haven’t smoked in 7 days as of today (woohoo!). my new gig starts october 3rd, but i have to get results to the new employer two weeks prior. i have no intention on smoking for the time-being, but naturally a bit fearful of failing this test. how many days would you think it would take for me to pass this test w/out doing anything different? a doctor buddy of mine said 30 days…but everything else i read says 10-14. what do you think? if you answer, then awesome!! if not, then so goes life. =) cheers and good luck to all when this dreaded day comes your way!! lol …ps…thanks!!

I am not wanting to insult you or anything like that, as I was an avid smoker for a very long time. I got into a little bit of trouble about a year ago and once I got out I decided enough was enough. I have a great job now, I get to travel all the time, I’m not worried about going back to jail, and I’m living a much more carefree lifestyle. I do miss it sometimes, but you have to have priorities. So instead of figuring out how to pass your piss test, *that your planning on smoking more before then* maybe you should just consider stopping. At least until you get yourself out from under the microscope. Just some advice take it or leave it. Also drink a bunch of water and do the vitamin thing a few hours before your test. They are not lying it works for sure, only problem is yours are random so this would have to be an every day routine for you.

Hello I have to take a urine test tomorrow, it has been 9 days since I last smoked and when I did it was only one bowl and I was sharing it with my friend. Do you think I will be able to pass you think? I have been drinking tons of water and taking cranberry pills like crazy. It was my first time smoking in 1 and a half months. Any help would be greatly appreciated.

smokeit August 12, 2010

You can drink enough water a few hours before your piss test to dillute the amounts in your system to pass, but your piss will need to have proper creatine levels and color. cranberry juice and b2 and b12 vitamins will color it. Take creatine monohydrate for your creatine levels. Or you can spend 55 dollars for a drink to dillute your piss down. The 55 dollar drink is for an average size person. Working out will only burn more fat putting more nanaboids in your piss making you more likely to fail

everybody just has to flood their system with dieuretics and water enough to piss almost clear and then use b vitamins to bring the color back to a yellow/orange tinge. then you can mask it even more by taking aspirin or ibuprofen. good luck.

p.s. workout and sweat your ass off for a few days before to flood it out as much as possible first.

Welp, my turn to freak out!
I used to smoke recreationally (1 maybe 2 times a month), but 2 years ago I was diagnosed with an incurable disease (it’s great, they have no idea what causes it and treatment is really hit or miss, and I’ve had all misses) that causes me EXCRUCIATING pain.
The docs and I have tried everything from narcotic painkillers (hydrocodone, percocet) to muscle relaxers (valium – helps, but only with the spasm portion of the pain) and analgesics. Nothing touches the horrible radiating pain though that rises up through my core and out through my fingertips and toes. I swear I’ve almost offed myself (if only I had the strength to in the midst of the pain) to try and relieve it. Then my boyfriend had a lightbulb pop up over his head – medicinal marijuana! I took 2 hits and the pain receded. I slept for 19 hours because I’ve been up for a day and a half reeling in pain (I literally bit my knee so hard I drew blood by complete accident – guess that’s where the term bite the bullet comes from! I needed something with less give!!!)
That being said, incurable disease is incurable. It’s not going away anytime soon, and once in a blue moon it goes into recession. It hasn’t recently, and flare ups can be brought on by stress. Well, I just got fired from my job for literally begging for a raise (I didn’t make jack and had no medical benefits and they were pissed I was missing work… well no ****ing duh). I do have two treating physicians out of state (I’ve moved here) and about to meet a free one later today to try and help. Regardless, I know what works and I’ve run the gamut.

I was smoking super high grade stuff about once a day for the past couple months since I’m not in remission. I’ve now gone 4 days without smoking. I’m 5’9 and 130 and obviously not terribly active because I’m in ****ing pain so much. I think my metabolism is a bit higher than average considering I had a desk job for so long, I eat pretty healthy (never fatty foods at least), had a recent blood panel done and lipids (fat) came back excellent (ie low).

Lucky for me the gods have smiled on me and the flare up is starting to go into remission again, but I’m scared to death about a drug test. The jobs I qualify for and want most require background checks (which is fine, my background’s squeaky clean) and considering it’s in medical, that probably includes a drug test. I’m obviously not worried about the valium, I have a prescription for that, but med. marijuana isn’t legal in TX (and probably never will be). At least I’m in liberal-land.

Is there anything I can do? I certainly have the time to start hitting up the park and hiking around, but I can’t do serious mega workouts or else I’ll bring on a flare up. Does anyone have any suggestions or any experience with luck like that? I need a job pronto and some are opening up that I’d love to have but I don’t know if I can somehow clean out/detox in time or if maybe a Dr’s note would do the trick.

Any input would be great. Thanks!

I forgot to mention that on the 5th, I only smoked 1 bowl and 2 bowls between 3 people on the 7th. And also, if we don’t have Purple Haze, we have Orange Kush, if it helps.

Hey guys
I have been smoking since February, 1-3 times a week, 4 someimes. Last times I smoked were June 5th and 7th. Every time I smoke, we average 2-4 bowls between 2-4 people. Normally it’s Purple Haze. Since the 8th, I have been overloading myself with water (1-2 water bottles every 2 hours, about 6 over the span of the day) and tomorrow is the big day. I have been urinating A LOT and drinking tons of water. It’s not a corporate drug test, but the take-home ones. Will I pass?

I’m 5’9 and I weigh about 135 lbs, I’m 16, nearing 17 years old.

Hey Dee,
I have a urine test tomorrow morning, and I’ve already been drinking water, taking various metabolism-speeding vitamins, and tons and tons of B-complex vitamins. You can read by the light of my pee, I kid you not. What I want to know is, how can I ingest monohydrate and sodium with only stuff around the house? I’m living with my parents for the summer and they don’t know I smoke, so I can’t go out and buy anything.

I did the same thing and passed. Go buy 3 cans of orange juice concentrate from a grocery store (it’s in the frozen food aisle) and buy like 4 gallons of cranberry juice. As soon as you can drink the orange juice concentrate without diluting it and exercise as much as you can for the first 4 days and then stop but continue to drink 4 glasses of cranberry juice a day. Go to the sauna a couple times also and you should be fine. Also buy detox 7 ( a 7 day detox program) and do that too. You can buy it at walmart or kroger. Good luck

Hi ladies and gentlemen. I have been smoking medical grade marijuana kush for about two years averaging atleast 7 bowls a day. Only cali’s finest top notch kush strains that i have been inhaling. Always been actively working out and have stopped smoking for about 32 days. I recently bought a home drug test kit *first check brand* and came negative with the results. What are my chances as having the same negative results in taking the drug test tomorrow?
