There’s a big chance you’ve heard a lot about the super popular QCarbo detox drinks. Maybe you’re one of the unlucky ones who are curious to see if it’ll work for your upcoming drug test. 

QCarbo is a line of detox beverages meant to cleanse you of any toxins and impurities. It is often used by those looking to pass a drug test. QCarbo can help you pass a urine test if directions are followed carefully. You’ll need to make sure to drink plenty of water and urinate frequently.   

Allow me to hold your hand through this stressful process of choosing the right QCarbo detox drink and how to better pass that test. Feel free to ease up, you’re in the right place. 

Does Qcarbo Work to Pass a Drug Test?

This is the most common question and most likely why you’re here. To put it simply, it can help you pass a drug test. It works by masking or diluting your urine during a specific timeframe.

Keep in mind that this is going to depend on a bunch of factors, though. This includes how much of a heavy user you are, your weight, and how closely you can follow instructions. 

But, it’s not just about following the directions on the back of the bottle. You’ve got to take extra precautions and steps that most people who pass follow when taking this stuff, which we’ll go over a bit later. First things first, you have to choose the right QCarbo detox drink. 

Herbal Cleanse QCarbo

If you know anything about Herbal Clean, it’s that they make pretty legit urine detox drinks. One of the other mega popular ones is Ultra Eliminex. Sound familiar? These guys are on top of it, to say the least. This can make you a little more confident that these drinks work a lot better than some of the other guys.

As I said earlier, you need to pick the right one. I’m about to go over the three detox drinks from the QCarbo line and what differentiates them from one another. 

QCarbo Clear- This one is for my smaller folks who occasionally or moderately smoke weed. It’s around 40 bucks and typically comes with 5 vitamin energy tablets that you take along with the liquid drink. 

QCarbo16- For those who have a small to medium body mass OR have moderate to frequent exposure, this is best for you. It’s also a bit cheaper than the other two. This only comes with the liquid, no tablets included. 

QCarbo32- Those who are on the medium to heavy side, this is the right one. It’s also for those with frequent exposure to toxins. This is the most expensive, at around $50, but it’s also the strongest. 

Here’s a rundown of the three products again:

Using QCarbo for Drug Test

So, you found the right Qcarbo drink. That step is done! Now we can get into the good stuff. I’m going to give you the best possible tips so that you’ll increase the chances of going undetected. Don’t worry, I didn’t forget to give you the instructions for each drink. That’ll be a bit later though. 

Let’s first get into the tips so you can better prepare and have an idea of what you’ll need to do. 

QCarbo Clear Drug Test Instructions

  • Try avoiding toxins for a minimum of 2 days. If you can, stop all use starting on the day you’re told about the test. 
  • Drink plenty of water the days before the test and right before taking QCarbo.
  • Try taking Zinc on the days leading up to the test. Zinc has been proven in many lab studies to reduce the detection of drugs like THC, cocaine, and even meth. 
  • Eat healthier foods, like fruits and vegetables. This can help with the detoxing process and to speed up metabolism. 
  • Start detox on an empty stomach, this is for better and faster absorption. Avoid food for about 3-5 hours before and after taking the detox drink. If you have to eat something, stick with crackers or something really light.
  • Follow QCarbo directions to a T. (They’re listed below)
  • Make sure you urinate 2-3 times after drinking QCarbo. This is when it’s usually diluted best. 
  • Try your best to take QCarbo around the second hour after you’ve taken it. This is usually the optimal time.

Keep in mind that most detox drinks take about 90 minutes to kick in. 

Does QCarbo Work for Opiates? 

It’s harder to tell, but I’d say they don’t work as great for opiates. Most of the good  experiences come from those who smoke weed or drink alcohol. Feel free to try it out for yourself, however. There’s always a possibility in can mask or dilute it as well. 

QCarbo Directions 

I’ve decided to include the general instructions that the Qcarbo products have on the back of the bottle. Since the instructions for QCarbo16 and QCarbo32 are the same, I only included it once so that I could avoid sounding like a broken record. 

QCarbo20 Clear Directions:

  1. Drink 20 oz of water.
  2. Wait 20 minutes. Drink QCarbo Clear drink with the 5 tablets.
  3. Wait 15 minutes. Drink 20 oz of water again. 
  4. Urinate frequently during the first hour. 

Instructions for QCarbo16 and QCarbo32:

  1. Shake the bottle. Drink an entire 16oz or 20oz of QCarbo bottle within 30 minutes. 
  2. Urinate frequently during the first hour. Drink plenty of water. 

Pretty simple and easy to follow. As I mentioned though, you’ll need to do these general steps along with the tips mentioned above so you can get a better result out of these detox drinks. 

QCarbo Detox Reviews

I don’t know about you, but I’ll read tons of reviews if I’m on the fence about something. You might still feel doubtful or unsure if you should spend your money on a drink that may or may not work. 

Well, I don’t blame you. Most detox drinks make huge claims and sometimes they flop. I’ll go ahead and leave some reviews that I found on the GNC website.

Used this product multiple times with no issues. Follow instructions and take 2 hours before test.” -Jeb 


Product was consumed with lots of water and did absolutely nothing. Waste of money.” – Smalls

Reviews on Herbal Clean QCarbo20 


Works great…for me, anyways. Been using this for years, several times. Just follow the directions, removed a “toxin” I partook in the very next day. Love this stuff.” -Greenlover


I haven’t smoked in a week. I’ve drank almost 6 to 7 gallon of water since I tested myself after drinking this and a ton of water today and every test I’ve taken has come back positive.” -Chris

QCarbo Vs Mega Clean 

When comparing these two head on, they’re very similar. Both come in a 32oz bottle and they’re around the same price.

However, Mega Clean seems to be less popular. QCarbo32 on the other hand, has more reviews and some are more positive. I think it’s best to go with one that is more popular and has more input from reviewers.
