QCarbo16 To Pass Drug Test In 2018? Best’n’Worst Reviews – StonersRetreat

When you’re looking for the best detox drinks to pass a drug test, QCarbo16 comes up sooner or later as one of the more popular herbal clean detox drinks for weed.

But how good it actually is? Does QCarbo16 really work for a drug test?

The QCarbo16 instructions are surprisingly simple: just drink the bottle of QCarbo16 before a drug test (it should work for 2 days) and you’ll pass the drug test.

With being so popular, this detox cleansing drink should work for everybody, right? Well…

qcarbo16 herbal clean
QCarbo16 is a herbal detox drink; it can help if you’re close to the cut-off rate.

With such easy instructions, I don’t think anybody should have a problem with how to use QCarbo16 (or it’s big brother QCarbo32). But is Herbal Clean QCarbo16 really effective when it comes to passing a drug test?

Yes and no.

If you have one look at herbal clean QCarbo16 reviews on Amazon, you can see two things:

positive and negative qcarbo16 reviews with more than 220 reviews
QCarbo16 has, at best, mixed reviews. Why is that?
  • About half the people (54%) just love taking QCarbo16 before a drug test and pass the test.
  • Roughly the other half (32%) obviously took the detox drink before a drug test and didn’t pass.

So which one is it? Does herbal clean QCarbo 16 work for a drug test or not?

Surely if everybody would pass a drug test with QCarbo16 there would be 100% of 5-star reviews.

And if nobody would pass? I would expect 100% of 1-star reviews.

The truth is somewhere in between – it does help a bit but it cannot guarantee you to pass a drug test. In a sense, it’s not a complete THC detox method.

We’ll go through the best and the worst QCarbo16 reviews but one thing is clear – QCarbo16 does not guarantee you to pass a drug test.

As it’s pointed out many times, there are only two things that will guarantee you to pass a drug test (and have been tested over and over again):

  1. All-In-One Detox: This consists not only of detox drink like QCarbo16 but is a complete detox program with the trio of detox pills, drinks, and dietary fibers. Toxin Rid line is the most reliable such detox – you can read more about it at our Toxin Rid detox review.
  2. Synthetic Urine: Basically lab-made urine that performs exactly like clean urine in a drug test. It’s usually the most common way for us stoners to pass a drug test. The only problem is how to heat it up to the body temperature but some next-gen synthetic urines like Sub-Solution comes with a vial that heats it up in no time.

I’ve made a summary of best QCarbo16 reviews and worst QCarbo16 reviews to figure out if this detox drink really makes you pass a drug test.

My first opinion: QCarbo16 doesn’t work! I’ll go into this at the end but will let you guys make your opinion about it first.

My findings: For some people QCarbo16 actually does work!

I’m quite impressed by these findings to tell you the truth. I was rather skeptical at herbal clean QCarbo16 at first (because come on, herbal drink? But then again weed is a herb and we all know it has an effect on us) but it turns out that your chances of passing a drug test are better if you drink QCarbo 16 before a drug test.

Needless to say, everything said about QCarbo16 is relevant for its big brothers QCarbo20 and QCarbo32 as well. The only difference is the dosage – 16 oz., 20 oz. or 32 oz. – the ingredients are the same.

The good thing when buying a QCarbo32 is that it might be twice the size of QCarbo16, but it’s not twice the cost – I think it’s like 10 dollars difference.

Herbal Clean QCarbo16 – Does It Work?

Here is my disclaimer: Unlike synthetic urine or Toxin Rid line (I use and trust, and it does have very good reviews), I haven’t used QCarbo16 personally. However, given this is believed to be a top choice for passing a drug test, I’ve gathered some interesting QCarbo16 reviews from all over the net.

Why?

Simple because we all want to get a clear picture if QCarbo16 does work for passing a drug test; or even better, in what cases does herbal clean QCarbo 16 work for a drug test (obviously it doesn’t work for everybody).

What Is QCarbo16 drink anyway?

In short, it is a detox drink. There are, however, two kinds of detox drinks:

  1. Cleansing detox drinks. Something like cranberry juice; they work by increasing toxin excretion by urination over a longer period of time (days, if not weeks).
  2. Masking detox drinks. These flush out THC out of your system and create a period of time wherein you’re less likely to fail a drug test. These are same-day detox drinks.

Obviously, Herbal Clean QCarbo16 is a masking same-day detox drink. Looking at the instructions, here is how you use this detox drink:

  1. Drink the entire 16 oz bottle within 5 hours of a drug test.
  2. Fill the bottle again with water, and drink all of it again.
  3. For an hour or so, there will be a rapid increase in urination. Translation: you’ll pee like your life is at stake (and it might even be).
  4. After the first hour, you should take a drug test within the next 4 hours. This is the time period in which your urine should contain significantly fewer toxins.

The step-by-step instructions give us a clear insight into what the Herbal Clean detox drink is supposed to do.

It effectively decreases the toxins such as THC from your urine and blood by almost forcefully peeing it out.

Of course, the THC stored in fat cells will try to redistribute itself from fat tissue into the bloodstream again. And after a while, those toxins will be detectable in the urine again.

And that’s exactly the point! During that time period, the urine should contain considerably fewer toxins.

How long does QCarbo16 last?

For about 4 hours. Take a drug test before that or after that time period, and you might be in bigger problems than within those 4 hours.

But by how much does concentration of let’s say THC decreases during that period – by 1 ng/ml, 10 ng/ml or 100 ng/ml? That is really hard, if not impossible, to say. Only a clinical study could evaluate how significant drop in urine THC concentration does Herbal Clean detox drink make. But we don’t have one of those in a file somewhere.

Alternatively, let’s look at the ingredients of QCarbo16 to see if everything checks out for the pee-toxins-out-for-some-hours scenario.

What Is Herbal Clean made of?

Obviously, it is a herbal cleansing drink made out of herbs. Here is the original labeling on the QCarbo16:

what ingredients in qcarbo16 made of
Ingredients include Vitamin B2, Creatinine Monohydrate and herbal root and leaf extracts such as Dandelion Leaf Extract.

Looking at the label, one thing is for sure: this Herbal Clean detox is sweet. It has pretty much the same sugar content as Coca-Cola.

We’ll look at every ingredient the QCarbo16 is made of (including the Eliminex Brand) and try to figure out why it is added and why it would increase our chances of passing a drug test:

  • Riboflavin (Vitamin B2). Herbal Clean contains a whopping 20 mg of Vitamin B2; that is 10 times more than a recommended daily intake of Riboflavin. Vitamin B2 is regularly added to detox drinks to bring the yellow color back to the diluted urine. According to a study published in Drug and alcohol dependence, the researchers found out that adding Vitamin B2 can be used to determine a patient’s medication adherence.
  • Creatinine Monohydrate. Drug tests measure for creatinine concentration; increased urination will dilute the urine and decrease its creatinine content. WebMD reports that creatinine clearance is 95-120 milliliters per minute. Detox drinks usually come with added creatinine monohydrate or creatinine monophosphate to bring the creatinine clearance levels up into the optimum (and non-suspicious) range.
  • Dandelion root and leaf extract. Dandelion is a well-known herbal detox preparation. Most of the natural detox remedies include dandelion root as well as leaf extract because of it’s presumed diuretic action. Much like drinking caffeinated beverages, the dandelion root is likely to increase the production of urine. An article published in the Journal of Alternative and Complementary Medicine shows that the frequency of urination was significantly increased by all of the 17 people who ingested dandelion leaf extract.
  • Turmeric root extract. It contains molecule curcumin that gives curry it’s yellow color. In detox drinks it’s used to color the urine yellow; of course, Vitamin B2 should do that job just fine. However, if laboratories are testing for high Vitamin B2 content, it’s better to use turmeric root extract in combination with B2. That’s how you need to add less of B2 and the concentration of Vitamin B12 will not be above normal on a urine test.
  • Juniper berry extract. In some studies, the ingestion of juniper berries or juniper essential oils is connected with a diuretic effect. According to Drugs.com, in classical use, 2 to 10 grams of juniper berries are used.
  • Echinacea purpurea leaf extract. Echinacea is a well-known medicinal herb that is usually connected to effects on the immune system. Why it is included in the Herbal Clean is not absolutely clear.
  • Ginger root. According to Medical News Today, ginger root can help with digestion by “stimulating bile production”. Toxin such as THC has to go through the liver in order to become more soluble in blood and urine. Bile excretes THC in the liver before it can go on to the kidneys and into the urine. By increasing bile production, the reappearance of THC in the urine can be prolonged. Maybe that’s why ginger root is used.
  • Licorice root extract. It is not completely clear why herbal licorice extract would be used in QCarbo16. One research published in the AAPS Journal investigated its effect on the key cytochrome in the liver – the P450. If, for example, the P450 is metabolizing licorice root extract compounds, it’s ability to metabolize THC can be decreased. The effect would be that we’ll find a lower concentration of THC in the urine. Of course, such action as the action of all herbal extracts in the QCarbo16 can have side effects.
  • Milk thistle seed extract. According to Dr. Axe, milk thistle a “powerful liver cleanser”. A large portion of different liver detoxification natural supplements contains milk thistle extracts. However, we cannot with any certainty determine why it would help to pass a drug test. In fact, if it lifts the liver activity, the more of THC from fat cells would be transformed by the liver into a water-soluble state (THC-COOH) and this would, in turn, increase the concentration of the toxins in the urine.
  • Uva ursi leaf extract. Uva ursi is commonly connected with the urinary tract infection. Tea made out of uva ursi leaf is a natural herbal remedy and including its extract in Herbal Clean is probably due to its diuretic effect.
  • Ligustrum berry extract. It is unclear why ligustrum extract is used. WebMD lists “liver problems” among the uses of this herb. Maybe it’s effect on the liver is somehow beneficial as far as drug testing is concerned.
  • Corn silk extract. Similarly to uva ursi extract, corn silk extract is associated with bladder and urinary tract infections. Here is an article that on side effects of corn silk extract.
  • Apple pectin. Pectin is arguably one of the most important ingredients of Herbal Clean QCarbo16. Pectins are basically fruit fibers that are most well known as an ingredient to make jam. It is considered the universal detoxification substance used in Certo and Sure Gel detox methods.
  • Guarana seed extract. Guarana is a source of natural caffeine; a substance that is a well-known diuretic. We find it in green tea, coffee, and many other drinks but it’s quite clear that it is included in the QCarbo16 in order to increase the urine production and elimination.

These are all the ingredients and it’s presumed functions.

Let’s start with the best reviews and then follow up with the worst reviews, shall we?

Best QCarbo 16 Reviews (more than 50% of users have such reviews)

With a product as popular as QCarbo line, it’s really not difficult to get reviews from people who have first-hand experience with QCarbo16 or QCarbo32.

Amazon QCarbo16 Positive Review

Amazon is where the most people buy QCarbo16 and it’s where you’ll find the most reviews.

This is an example of a verified customer that obviously has some experience with QCarbo.

amazon qcarbo 16 positive review

You can see that Gabrielle claims that QCarbo16 does work, and for her, it did work on multiple occasions. What I like about this review is:

  • Making sure to follow QCarbo16 instructions.
  • It does make you urinate more if you drink plenty of water. Sounds like the weed (or other drugs) are being washed out of your system.

Two sound pieces of advice for using any detox drink.

QCarbo16 Review From Marijuana.com

Marijuana.com is a very credible source of information about weed and people there join a forum to share and discuss different things. One of them does QCarbo16 work for a drug test as well, obviously.

Here is a screenshot of a story about a guy who passed a drug test using a lot (and I mean a lot!) of cranberry juice, and QCarbo 16.

qcarbo detox story
Guy passed with QCarbo drink.

I really like the story and am glad that the guy passed his drug test. Obviously, he used QCarbo 16 but he did gulp down a lot of cranberry juice as well. Both of things made him pee more so I guess that is weed going out of his system.

Here is another testimonial from a weed blog by ‘B money’ (forgive him for using crazy grammar, he gets the point across):

qcarbo review thcclean

Thus far the herbal clean QCarbo16 looks pretty awesome, right? Just do bear in mind that these reviews are the positive ones. According to the Amazon rating, 43% of people who used QCarbo 16 didn’t like it one bit.

Let’s look at the other part of the spectrum.

Worst QCarbo16 Reviews (less than 50% of users have such reviews)

Every product has bad reviews as well and QCarbo16 is not an exception.

Here is one of the worst QCarbo16 you can see.

amazon qcarbo 16 negative review

Maria kept is short and to the point – Qcarbo16 didn’t work for her.

The absolute worst review I found was on the drugs-forum.com, a well-known weed forum. Here is the answer to the question if anyone used QCarbo16 to pass a drug test:

qcarbo works drug forum

Yeah. If you thought that losing your job is the worst thing that can happen when failing a drug test – think again.

Albeit Percocet does include oxycodone, a strong opiate, and if you’ve tested positive for the opiate abuse you can get a week of jail time as well. The law is, of course, not as strict for weed.

My Theory for QCarbo 16 (works as a final push)

Reading through the reviews, I noticed that more than half of people (51%) were happy with QCarbo16 and less than half (43%) was not.

This is probably because 51% of people passed a drug test by drinking QCarbo 16 before a drug test and 43% didn’t (and lots a job or even got jail time).

If we look at passing weed drug test (weed is the #1 illegal substance people test positive for on a drug test), you can see that more than half would test positive if they were to smoke a joint 1-10 days before a drug test:

thc detection times
More than 50% of people are still THC positive within 10 days after the last joint.

As I’ve stated earlier, I find these findings quite impressive! Obviously, you have a better chance to pass a drug test with QCarbo16 than without.

It also isn’t one of those ‘well, it can’t hurt detoxes’, it does actually help some people.

Here is my take on why it helps some people – because they are really close to testing negative on a drug test anyway. In 1 or 2 days, the drugs would be flushed out by the system itself. However, QCarbo16 makes you pee quite a lot and you eliminate the drugs that would be eliminated in 1-2 days after the drug test.

Positive Outlook on QCarbo16 (Surprising But Effective Last Resort)

Maybe not a big difference, but a decisive one: with QCarbo16 some people can pass a drug test.

As a general rule, if you have a week, the 5-Day Toxin Rid is still the best solution to passing a drug test. I would use QCarbo16 as a last resort, but surprisingly an effective one.

The same principle goes for QCarbo20 and QCarbo32. Those are just bigger doses you have to get if you are:

  • Heavy user. The more THC you get in your system, the more you have to flush out.
  • Being overweight. The more weight you have, the more THC is stored inside your body, hence the bigger does of detox drink to get weed or other drugs out of your system.

    So this is my bio: I’m 31 years old, 200 lbs and 6ft tall, a little overweight I know. I was a heavy smoker (smoked everyday for years), and I had stopped smoking March 3rd, but smoked again on April 29th (only a few puffs off a joint). I don’t need to get tested until early to mid June, and it’s May 4th right now. What do I need to do besides abstaining from smoking in order to pass? To sum up: I was clean for about 56 days, I had a little hiccup this past Saturday, but still have 35-40ish days (since the last time I smoked) before I get tested.

    Ready to drink detox will pass your drug test, you MUST FOLLOW THE DIRECTIONS! It must be taking at least 3hours before testing to allow drink to work and your body to urinate the toxins.

    My opinion of the 43%that did not like this q Carbo 16 is that they likely have more body fat,and or continued dumping toxins into their body all the way up to the time of testing and even after taking the drink yet before testing. I would suggest stopping all toxins as soon as you become aware of your need to be tested, drink plenty of water, urinate frequently, and pair this with the q Carbo. If this doesn’t sit well with you then try the synthetic urine or the detox pills. I am experimenting with trying to pass for thc and fail for tabs. Ill post again when I have results.

    Hey everyone!
    I wanted to share my experiences here because I really hope this worked!

    I work in the healthcare field and hate my current job to no end. I started smoking about a month and a half ago casually and lightly to help relieve stress, of course never on the job, always after I got home from work and before bed to just to relax. I applied for several other jobs in my area and got a call back quickly. I went in for an interview and they basically told me then and there that they wanted me. I was expecting for the official word from HR to come a few weeks later. This HR rep is notorious among the facility and community for taking FOREVER to get in touch with people they want to hire. My friend waited 2.5 weeks before having to call her and she told her, “Oh sorry, I forgot to call you!” So I truly thought I would have plenty of time to get it out of my system and pass. I know, I know, I’m a complete and total idiot and I have more than learned my lesson. I have had at least 3 panic attacks about this whole situation.

    So I left the interview and got a call back within an hour of leaving. The HR rep gave me the info and told me that I needed to have my drug test completed by close of business Friday. This gave me 3 days to get clean. I took several at home tests, many with VERY VERY VERY faint negatives. I’m talking it looked like a shadow faint. I didn’t trust it. This morning before leaving for work I took another one and it was actually positive! I bought this bottle of QCarbo16 months ago when I wanted to do a cleanse and didn’t realize that THIS is what it was for. lol. So I did exactly as told, drank water all the days leading up. Today I drank water, ate only crackers for lunch and then at 12:15 started to drink the detox drink. Then I refilled it with water and drank that. Refilled it with water and drank that again. I peed several times during this. My test was at 2:45, so I came home, took a home test at 1:45 and I PASSED WITH A STRONG NEGATIVE!!!! I was so damn excited, I could have cried. It takes 30 minutes to get to this place, so I immediately got in my car, went to the appointment and gave my sample. The nurse did comment on how bright yellow my urine was (the drink made it almost a diluted neon yellow) but I told her that I drank a Java Monster earlier in the day and it usually turned my urine that color (because that is actually the truth, it does turn it that color.) Everything went along great with that process and I left. I went to get something to eat and took another home test in the bathroom there and it was still negative. So I’m very hopeful that I passed.

    The facility uses Quest Diagnostics so I am just trying to patiently wait for the next week or two to see if I get a call back from HR to come in. I’ve read online that Quest will call you before reporting any positive results, but I’m not sure how true that is. It’s Friday so of course I’ll have to wait the entire weekend and possibly until the end of next week to hear anything. I’m very nervous but I am VERY hopeful! I’ve had instances before where if I passed the home test then I passed the Quest test, so I’m hoping this is okay. If it’s not, then not only is the new job off the table, my entire healthcare license is on the line.

    I understand that many people may have negative things to say about this, but my very very casual smoking has NEVER influenced or affected my work, my work ethic, or my passion for my job. I have very much so learned my lesson and will never partake again. I’ll miss it, but this is too close of a call for it to ever be worth it again.

    I will come back to post whenever I find out what is going to happen!!! Please send good vibes and thoughts as I deal with the stress. lmao.

    I smoke regularly, not all day but atleast 3 times a day. I have a drug test in about 4 hours for a job. I got 2 drinks. One a cheaper one (champ) and qcarbo16 dont have the 32 oz. Qcarbo worked for my brother last week but he is smaller than me. I’m slightly overweight which is why i got 2. Ive been drinking water basically non stop since last night. I hit a blunt 3 times last night an a small bowl yesterday morning. I woke up and drank the cheaper one first an still chugging water. Been to the bathroom half dozen times. Going to drink the Qcarbo in a little bit so i hope it works. Any of my stoners on the heavier side had any luck with these?

Was locked up for 27 days, didn’t smoke during that time, and Havnt touch weed since before I was locked up Whitch would have been Aug 15. Why am I’m coming up positive still!? Thanks

      Weed (or more exactly, its active component THC) is stored in fat tissue. In the case of chronic users a lot of it can be accumulated over time and is then released – this is one way a person can be positive even up for 2 or 3 months. Energy drinks, unfortunately, do little or nothing as far as weed elimination is concerned.

      Hope everything will be ok on your test!

    I’m New to this weed thing. I had one puff on a train two weeks ago and then I had one coffee bean edible about a week ago so I am not sure if this stuff should still be in my system or not. I took a home drug test and it is very confusing so I decided to drink the detox. When should I drink it if my test is Tuesday at 10 am? I’m confused with the directions as well. Please advise and thank you.

      Low body fat percentage is as efficient at passing a drug test as is the 6-pack at picking up girls – it’s good to have but it’s not a guarantee. As I’ve said before, these natural ways of passing drug test such as sauna, cardio and so on are only effective if you’re close to the cut-off limit of the drug test. QCarbo16 is the same – it helps a bit but it’s no guarantee – as you’ve seen from the Amazon reviews, 43% of guys who used it were not impressed. I would really advise using the calculator below which points out if you should use synthetic urine or Toxin Rid detox (only one detox that consistently works, not like QCarbo16).

      I’m really sorry you didn’t pass, Smokey. What was the aftermath of not passing?

      Here is the calculator:

        I did a home test first but there is a job on the line by the end of the week and they will do a temperature check instead of watching my wee wee. I was more just sharing my experience because so many people besides the amazon reviews you provided swear by this product. The stupidest thing about it is that marijuana is legal in my state for adults over 21….

          The greatest ludicracy I see is that 1) Marijuana is legal but 2) You must not be THC positive on a drug test. I mean, what’s the point of legalization if one cannot earn a decent living because of smoking weed? I think law for legalization and drug test should go hand in hand. Hope this will be fixed soon. Thanks for sharing your experience, Smokey!

      I believe you are supposed to limit exercise until after the test. Exercise releases the the metabolites that will make you test positive since it is stored in your fat cells. Try not exercising for a few days before testing next time

      That is usually the right way to use QCarbo16 – peeing several times is a strong indication that it works; just do bear in mind there are no guarantees as with synthetic urine.

          The QCarbo16 cleans the system for 2 days. Honestly, you have better chances of passing a drug test with QCarbo but not by much I think. The real detox here is Toxin Rid and of course synthetic urine is the most popular way to do it by far.

          Hope this helps. Best, Steve

            45 days is quite a long period. You probably should be fine without it.
