Product Description

The Marijuana Detoxification Kit includes a 20oz bottle of QCarbo, one pack of Super Boost Tabs, one QTabs Cleansing Detox Supplement and one THC-marijuana test device.

How It Works

This kit works by combining diuretics (a substance that increases the frequency of urination) with increased water intake.

Using this method works to rid your body of any THC metabolites that have accumulated due to cannabis consumption. It is a technical and complex mixture that resembles a diuretic itself while adding and diminishing the correct amount of chemicals and compounds to and from your urine.

Just drinking a large amount of water while taking ‘normal’ diuretics will not work.

Why? Because your urine will become too diluted and test givers will be aware that your urine has been tampered with or you are attempting to cheat the test.

This method will also more than likely mess up your creatinine levels which are also tested for in a urine drug test. To ensure your creatinine levels, THC levels, level of dilution and more are sufficient to pass a drug test by providing clean urine, use this detox kit.

This product gets five stars from me :) read the directions and followed them exactly.... except when it came to chewing the vitamins .... my stomach couldn’t tolerate it, so I cut them into smaller pieces and swallowed them. They did make me puke, and after voiding about 6 times I finally gave a negative result! I did buy a few extra THC tests from the dollar store to make sure I had a negative test before I went in for my screening. Don’t feel scared if you test positive, just try voiding a few more times.... that part is crucial! Thank you Mr. Miller for a product that actually works!!!!

I just wanna say thank you to Green Fleets for a product that works and for their great customer service. I'm a female, 5'8", 130 lbs and a moderate smoker, and I found out I needed to test for a position I applied for and that I had 3 business days to do it.

Prior to my test I had stopped smoking for about 2 weeks, and I normally drink water and work out a bit, but I had smoked with some friends earlier in the month and I just knew I was going to drop dirty for the lab test that was coming up so I wanted to be safe. I scheduled my drug test on a Wednesday, the third business day, to buy myself time to order the test and try to flush my system.

But because I ordered my test on Monday around 4pm to have it sent overnight, I got an email stating that it wouldn't reach me until Wednesday, the day of my test. Needless to say I was shxtting bricks. I emailed them back letting them know I needed the test by Wednesday morning and if I wasn't able to get it that early then I would like to cancel the order and take my L.

The rep emailed me back told me that I would get my test by 10. Luckily I had my test scheduled for 2pm, and 10 am would be pushing it but I took my chances and ordered it anyway. And I prayed. All Tuesday I was a nervous wreck and I drank so much water my urine was clear.

That night I took two dollar tree marijuana tests and both came back negative, so that made me relax a bit but I was still skeptical because I'd be taking a lab test and I was sure the test would be more sensitive. As promised my test was on my front door by 10:30 the next morning, thank God.

Before I took the detox I tested my urine again, just to see if I was truly negative, and it was positive! So my anxiety kicked in and I chugged the detox with the 5 tabs and drank two glasses of water, one before the detox and one after. I had a pretty decent breakfast that morning so I was so full of food and water, I was 'bout ready to explode!

I peed a good four times before my test, and by the fifth pee, I was ready to drop. Went to drop for my job and that was it. I waited anxiously to hear that my test came back negative...but the next call I had was my job letting me know that my background and my drug test was clear and I got the job!

I start tomorrow!! I'm so geeked, and I'm SO thankful for this product, and the reps who made sure I got my test on time. This truly works, I promise I'm not a paid sponsor, just a regular girl who likes the occasional hit of a nicely rolled blunt from time to time who also needed a decent job during these hard times. And I got it! much love and many thanx! Xo, Rae

1st order this product. I have been smoking for the past 15 years every night. I went for a new job then I was told that there would be a drug screening I was worried but I found this product it came to me in a timely manner and very discreet. Follow the directions on the web site word for word.I was told 3 days later that the job was mine. Thank you so much for the service you provide.

A friend recommended me this product. There’s a lot of reviews here and honestly the “I promise this is a real review” comment in multiple of them look...sketchy, to say the least. But I am here to say this is a *very* real review and I’m STUNNED with this product! I found out 8 days before my drug test that I’d have to take one. I stopped smoking that day, worked out every day up until the two before hand and ate like shit the two days before (read about this on Reddit). Also took B vitamins the day before and day of. Followed directions on the box perfectly. At home test that was provided was negative, immediately went to LabCorp for my actual test. Got the job :) also did research on the CEO of this company and he used to work at labcorp. Anyway, this product is legit, will buy again if ever needed and will always recommend to a friend.

Worked like a charm for me! I had a couple weeks to get clean for a job interview but have been ripping a dab pen for about a month straight. I drank a ton of water and exercised a lot leading up to the test date. I followed these instructions and passed with flying colors!! Buy this product!!!

i'm a 5'9 female that weighs 275 pounds and i was very skeptic about any detoxes possibly helping me due to my weight and how much i smoked. my friend had tried this detox and passed and got a job so i figured it was my best bet. i had quit smoking for a month and increased my water intake. woke up the morning up my drug test, followed the directions and within 2 hours i was clean. there was a lot on the line. yesterday i found out i passed my drug test and i start in a couple days! this was a life saver. if it weren't for this kit, i would have never landed the job.
Simone -
I followed the directions and I passed. However the drug test they gave showed up positive!! I would recommend giving yourself 3-4 hours for it to kick in if you are a heavy smoker. I don't believe it worked in 90 mins for me. I will definitely buy again!
Samuel -
It does work very very well follow the directions and you will pass I did it the same day and passed

I am the most paranoid person ever and this was the first time I ever was taking a drug test – I am around 148-150lbs and 5'4. I smoke everyday for almost a year with dabs or flower or edibles. I am consistently high so when I had to take this drug test I was freaking out cause I don't think that gatorade and sugar adder will work on me. So I took this drink plus the pills holy shit those pills were nasty af but the drink itself tasted good. But the amount of liquid you are ingesting def will make you sick even close to vomiting. But I passed! Again I was spiralling thinking I wasn't going to pass or anything, the first time I took the drug test I stopped smoking for 5 days and when they made me take it again I stopped smoking within 24 hours cause I didn't know they can drug test you a second time??? Anyways I passed and got the job ?

I was soooo scared that I was going to fail and go to jail & I passed!! I am 102 lbs, 4'11, I don't drink water on a regular or stay “fit”. I didn't finish the whole drink because it was so fucking nasty, but I drank the water before, took the pills with the drink & drank about 3/4th of the bottle and then took a few practice test I got from the dollar tree. I threw up, not going to lie, but I still passed when it was time! I'm rolling up while I'm trying this because I'm a free woman!!

I was very very VERY hesitant to buy this product because all the reviews were so good they seemed fake, but this product really works! A LIFE SAVER. I am a 5'9 female about 160lbs and have been smoking about 1-4 blunts a day for the past 3 yrs. I have to take monthly drug test and only had a week to clean up. I WAS FREAKING OUT cause it would have been impossible to flush my system naturally in just a week. So in the days leading up to my test (about 8-10) I stopped smoking completely & I drank about a gallon of water a day (8 bottles) but that was all. When i got this product i followed the directions word for word (i recommend using the ones on the website as well since the ones on bottle are fairly vauge) and peed about 6 times through this process (your pee will be clear at first but as you continue to pee and take the Qtabs the color will change to a bright yellow, this is normal) the drink isn't terrible but i don't recommend chugging, drink at a normal pace in the span of 30-40 mins with the 5 vitamin pills. I didnt get chewables, instead I got Qtabs that i just swallowed w water. I tested myslef at home 3x before my test and they all came back negative! (wait at least an hour before you start testing) I peed after ever bottle of water i drank w the Qtabs and on my last 3 Qtabs I downed them with water and held that piss in until it was time to take my test, dont get the first or last catch of pee in the cup. They told me that day i passed which means no jail for me!! I believe the longer you stay aways from smoking the better but still a great quick fix to al the heavy smokers out there. Definitely worth the purchase! side note: after my test i threw up a little from the Qtabs. i belive its from taking in so many liquids on an empty stomach but besides that everything was great! Thank you Green Fleets!!

Very fast acting and actually works. I drank a shit ton of water with it. The chewables were absolutely disgusting but worth every penny and tortured tastebud. My pee was neon yellow and i was freaking out about them saying something about it. They didn't. I passed my test. This test was a f##king life saver. I would buy this again if I need it. I recommend this to everyone who needs to pass.

For starters..4 stars d/t horrible customer service ..opens at 9 am EST but no answer for entire hour until i tested. Now for review. Everyday smoker for many years. Stopped for little over a week then wigged and hit one time less than 48 hrs prior to testing. My package came discretely packed..10 chewables..yep 10..not three..10. So I called and called with no answer but sent email and got a reply email at the 11th hour..take all 10 according to package directions. I couldnt handle more than 7..on package it says chew four..followed by water then for "comfort" wait 20 min and take three more and then three more for "comfort". I ate lightly the day before..havent hit gym in a week..first test positive second test about 45 min later was barely negative which my comfort needed three more of the nastiest sh ever..stains teeth..hold ur nose and gulp the water... brush teeth like never before..chew gum.. Went to lab and barely I mean barely passed and was ask if i took any meds..yes i said along with my script and otc meds I take cbd oil (not regulated, so i fibbed) luckily "lots of folks are coming up positive on cbd" swore not to use that anymore..but any faint negative line is negative. I'm 5'5, 158 lbs

I was very skeptical at first. I read numerous reviews and researched the ins and outs of THC detoxing for a drug test. This product is great because it dilutes your urine and puts the correct nutrients in your urine for your test. I passed my test! I was thoroughly excited. I bought two kits so I can save the second one for a friend or a rainy day! Thank you Green Fleet!!!!
James -
It fu***ng WORKS!!! I was so skeptic about it. I did it exactly according to the instructions and it worked. I drank water then the Bottle with the 5 pills then I failed the at home pre-test. I chewed the three chewable “pills” and took off to the clinic. I urinated twice (on my way there) before the test. I took the test and PASSED! The only side affect I had was nauseous but nothing crazy. I weigh 235 pounds. This product is awesome.

It worked, but the taste was terrible...

So I'm not at all getting paid for this at all just an FYI! When i received the call I got the job and just had to take the drug test i was shitting bricks. Lol I smoke about 5-6 bowls a day and have been for about 4 yrs steady. But when I got that call I stopped smoking and I instantly googled THC detoxes and this one came up and I went straight to the reviews and then read the ingredients was sold and ordered. I stopped smoking for a total of 5 days and during the time I went to the gym a few times and hit the sauna. I drink a lot of water normally so that wasn't a real problem. Come test day I started the detox 3 hrs before. I ate a bagel with cream cheese before due to me having a sensitive stomach. I waited 15 mins after eating to start. I then started steps 1-4 peed the amount of times instructed and then took the at home test. Positive for THC! I was freaking out. But proceed to do step 5 ! Those chewables are nasty af !! Lol I legit almost barfed. Having a Gatorade to wash it down helped. But don't drink to much of it. Went on and drank the amount of water as Instructed and peed like crazy. During the time of peeing pay attention to the color. When I peed before i left my house it was yellow. When I went to take my test it was a light neon yellow green and I had read that was the color it should have been. And that gave me some ease. I then waited for my job to call me And at this moment I'm just waiting for my work schedule. This stuff really works. I was really skeptical at first but honestly it works. I have already told my family (were all big stoners) to use this. If you need someone to believe on here, please believe me it works. <3 Side note: you might get a headache the next day and I found only drinking a cup of coffee helping it go away. Medicating and medicine wasn't working.

What the... IT WORKED! :) I stopped smoking 48 hours prior to my test. I was drinking lots of tea and water; plus I was running a mile and using the sauna everday. I didn't have enough time this morning to take the chewables- gladly lol- but everything STILL WORKED OUT. Absolute gold.
Anon -
I was extremely skeptical. I've been smoking for 2 years, 4 days a week. I had to get a urine drug screen that also check pH, specific gravity, and temp. I failed one before from just taking the B vitamin, my urine was marked diluted. Took this. As directed. Wanted to better the odds to I chewed those 3 big chewables. A drank Gatorade when plugging my nose. Lol. Took the test. Nervous for almost 2 days thinking that I failed. Long and behold I passed! Even with all the strict checking for dilution or tempering. This is worth every dollar!!

I was a complete skeptic on this product however I passed a lab exam. I smoked every day for 8 years large build. I followed the instructions to the T and boom passed with flying colors. I did buy a home test to try before the tablets and I was passing then but didnt want to take the chance so I went worst case and done no questions would use again if needed.

This product is simply amazing. Period! I was stuck in a dead end job and wanted to better my career. I applied for numerous jobs and got a call for an interview on a Thursday. The interview went excellent and things progressed really fast and I had to take a drug test that following Tuesday. Being a heavy smoker, just stopping smoking is hard, so I only abstained for 48 hours. I initially used a different product, Jazz Detox, and ended up failing my drug screen. THC positive. Naturally, I began smoking right after that drug test. To my pure luck my sample got "miss-handled" at the lab and I was allotted to take a second drug screen. I researched and researched an astounding amount of varying detox products and this was the only one with a 100% money back guarantee I found. So I figured it was my best shot at passing. Once again, to my luck, there happened to be a intense winter storm that rolled in and snowed everyone in, so I was able to abstain from smoking for 6 days before my second drug screen. I knew I would test positive for THC even after 6 days as I am a heavy smoker, typically 3-4 bowls out of a very expensive bong everyday, some days even more than that, especially on the weekends. I am a female 5'9" and 140lbs. To put it lightly, I really wanted this job, but figured I was screwed. Throughout those 6 days of abstaining, I stayed as active as possible, up until 36 hours before the test. I also took B-12, B-2, Creatine and Activated Charcoal supplements and drank an ungodly amount of water along with an insane amount of vitamin C. I also ate fairly healthy throughout those 6 days. It was pretty awful, not going to lie, but well worth it for getting this job! So, come test day, I called in sick to my current job. I didn't want to be rushed at all on this day. I took an at home drug test and clearly failed. I than began the process laid out in the directions and followed them to a "T". After drinking the bottle and water along with the 5 pills, I peed 4 times than took the drug test provided in this kit on the 5th time and was clearly positive for THC. I was freaking out!! And that's an understatement; I really wanted this job! I also had bought 5 other at home drug tests. So I continued onto the additional steps and ate the 3 chewable tablets provided; and let me tell you, it was the most disgusting thing I have ever ate in my entire life. I almost vomited. The only thing that kept me going was pure willpower and drive to get this job. Absolutely disgusting!!!! After eating the chewable tablets I peed 3 more times than took one of the at home drug tests I bought on the 4th time and still tested positive! Needless to say, I about had a heart attack and pretty much put my mind to the fact that I was not going to get this job, and just missed out on an amazing opportunity. So I peed another time and than when I peed again for the 6th time after the chewable tablets and I took another one of my at home drug tests and saw a faint line; and when I say faint, I mean extremely faint line. I even took a picture of it with my phone and zoomed in to see it better. I figured I was screwed, so I just went to the drug test center and took the urine test. The next day, less than 24 hours later, I got a call from my new employer and I passed!!!! I was in utter shock and disbelief!!! This product really does work, and is worth every cent!!!!! Highly recommend!!! And no they did not pay me to write this, it does actually work!

Let me start off by saying I am not endorsed by this product. This company is not paying me to write this review. I am just a regular woman who was trying to find an easy way to pass my test. And I am sitting in my math class as I write this. I am 22 years old, at a weight between 155 and 170. And I am short (4'10”) to be exact. And I have been smoking weed ever since I was 15. I smoked 1-3 bowl packs every day, sometimes more depending on the day. I also smoke Dabs when possible. I work currently as a security guard, for a security company that I learned is losing a contract with the site I work at. The security company taking it over offered all of us at that site a job with them for more money than we are currently making. However - due to this security company being far more professional, I was told we would all have to take a piss test. When I heard that, I was freaking out major. I've never had to do that. Only ever had to do saliva tests. (Which I bought mouthwash from this site for both times and I passed both times. But that's another story) so I decided to buy this product after spending DAYS reading and re reading the reviews by everyone in the review section. (I read all 82 reviews it had). I bought the product two weeks before the test. And it got to me in a few days. With expedited shipping. (Their shipping options are very helpful especially if you're waiting the day before the test) I had to take my drug test this past Friday. So what I did, I stopped smoking for 5 days. The bottle says to stay away from toxins for 48 hours. But that the longer you stay away from it the better. I started my detox regimen with this product around 8am Friday morning. And I followed the directions on Both the website and on the bottle to the letter. I gave myself two hours before having to take my test. I peed 3-4 times after drinking the water and the drink and the 5 pills. At first I was peeing clear as if it was water Which really scared me at first because I know the test givers would question it. But I continued following the directions. My pee after the second pee was now a neon yellow. Which I read is normal, based on the reviews here. I took the at home Test the product came with. And the product said I was clean. The second line was a little faded. However the test itself SAID I passed. So I skipped step 5 as the directions told me too (I'm happy I didn't have to do step 5 cause those pills apparently taste like dog food. I went to the drug test. And I took the test with no issues. I received an email from the company that I passed and am now officially an employee with their company. This product. Really REALLY works. I was so scared I'd fail. But I passed and I couldn't be happier. The only warning I would have about this product is that the next day I ended up having the WORST headache I could have ever had. I don't know if that was from the product or not. But I'd rather post it here in case it is. I hope my review can serve as a reason to trust this product. Cause I did. And I could not be happier

I am a daily smoker, not heavy, but daily and have been for over 40 years. I've both passed and failed tests before using similar products. So when I saw all the reviews, I was skeptical, but I'm here to say that this product does what it says it will. I found out a week before that I needed to pass a UA. Needless to say, I was worried. I stopped for the 6 days before my test and on the morning of the drug test. I followed the directions exactly. I was a bit apprehensive even after the self-test showed I was negative so I did eat the 3 foul tasting pills and drank the extra water. Today I found out from my prospective employer that the job is mine. Thank you for this product!!! It DOES work!!!!
