Got a drug test coming up? You’re probably worried about the results. Passing a drug test is incredibly important, especially if you’re a marijuana user. Here’s the good news, you can pass a drug test and all you need is to make some wise decisions. In this post, we’re going to list some of the most important tips and tricks, alongside other info you should know about marijuana cleanse. 

How long does weed stay in your system?

Various factors determine how long THC stays in your system. They are:

  • Metabolism and eating habits
  • Frequency and quantity of marijuana use
  • Body fat percentage
  • Exercise routine and how active you are

Due to these factors, it would be difficult to identify a single standard detection time regarding how long it takes for THC to leave your system. Basically, THC can stick around for anywhere between two days to several months. However, for most cannabis users it takes about one month of abstinence to eliminate THC and pass the drug test. But there are no guarantees here because every person and their metabolism are different. 

How do detoxification and detox remedies work?

A wide range of marijuana cleanse remedies is available today and it’s natural to wonder how they work; more information here https://fmahealth.org/marijuana-cleanse/.  Their mechanism of action is simple – these products can lower THC levels through their diuretic properties. 

When you consume teas and detox drinks for weed, you need to urinate more which allows you to flush marijuana out of your system. Some products also work to mask THC metabolites so they go undetected on a drug tests and induce a negative result. 

Studies about weed detox and THC metabolites masking

Even though marijuana use is common today, studies about weed detoxification and THC metabolites masking are scarce. Hopefully, in the future, we are going to witness more studies that will focus on the mechanisms of detox and THC metabolites masking. The more we know about the subject, the easier it will be to do a marijuana cleanse for a drug test.

Studies show that cannabinoid metabolites have been detected in the urine of frequent cannabis users for prolonged periods during abstinence from cannabis use. During the terminal elimination phase, alternate positive and negative drug test results may occur in consecutive specimens. This makes it complicated to determine whether positive results are indicative of new drug use or reflective of previous cannabis exposure. That’s yet another reason why drug tests, especially in working environments, have become a subject of numerous debates as many people claim it’s unethical.  

Within five days, a total of 80% to 90% of THC is excreted, primarily as hydroxylated and carboxylated metabolites. Over 65% is excreted in the feces, while about 20% is eliminated in the urine. Numerous acidic metabolites are found in the urine, primarily the THC-COOH glucuronide conjugate. The slow release of THC from lipid-storage compartments and significant enterohepatic circulation contribute to a long terminal half-life of THC in plasma, which is about 4.1 days in chronic cannabis users. 

At this point, there are only two substances that have been shown to help cannabis users pass a drug test. They are papain and zinc. Papain is a proteolytic enzyme extracted from the leaf and raw fruit of the papaya plant. Papain lowers a person’s THC metabolite limit while zinc helps mask the THC metabolite levels for a window of time and increases your odds of passing a drug test.

Natural detox methods

Natural detox methods prove to be the most convenient and effective strategies to eliminate THC from the body. Let’s take a look at some of the most useful things you can try.

What is the best detox drink for weed

Probably one of the best detox drink for weed is Rescue Detox Ice Drink, which relies on B-complex vitamins such as B1, B2, B12, and B6. These micronutrients boost energy levels and give a urine yellow color to mask dilution. Additionally, this detox drink contains vitamin C which is vital for cell metabolism. Other ingredients include sodium to provide electrolytes and potassium to provide electrolytes that prevent water intoxication. This detox drink also contains Stevia leaf extract, fructose, hydrolyzed collagen, cranberry, and pomegranate extract.

Fruit pectin

Fruit pectin works just like fiber – it enables the body to absorb and expel toxins via your fecal matter. Fiber is crucial for digestion and regular bowel movements both of which are necessary for expelling THC out of your system. As seen above, a certain percentage of THC in the body is expelled through feces. In other words, fruit pectin works more effectively than “regular” fibers and it improves the body’s detoxifying processes. 


The importance of exercise for the elimination of THC is immense. First of all, exercise supports a healthy lifestyle, which is crucial for the proper functioning of the processes in the body including your detox. At the same time, physical activity makes you sweat. As you’re aware already, sweating is yet another way to get THC out of your body. 


A sauna works on the same principle as exercise – it makes you sweat quickly. When sweating you get to eliminate a certain amount of THC from the system. Make sure that alongside the sauna you’ll also have to stay hydrated throughout the day. 


Diluted urine can make it easier to pass the drug test. It could be one of the fastest ways, actually. Nowadays, many products allow you to do so, but you need to follow the instructions carefully. It’s easy to make a mistake with dilution and risk negative results. The whole point of dilution is to mask THC metabolites and ensure the drug test doesn’t detect their presence. Keep in mind urine should still appear natural. 

Can lab tests detect THC detox products?

No, they will not. Consuming THC detox products is, basically, just like drinking any other beverage. These products don’t leave traces in the urine. Plus, laboratories don’t even test for the usage of detox products, they only analyze for the presence of THC metabolites. What’s important for the labs is that your urine is not diluted and whether you’re following instructions properly. The sample needs to look natural and you shouldn’t show signs like you’re attempting to tamper with the urine sample. 

Do I need to detox if I’m an infrequent user or took an edible?

It can take between one day and 30 days to flush out THC from edibles. If you’re an infrequent user or you took an edible you may still need to detox. This is particularly the case if you have a drug test coming up. Although you don’t consume pot regularly, infrequent use (and edibles) still leaves THC in the system. The presence of THC can be detected on the drug test regardless of whether you’re an infrequent or chronic user. So detoxing can be quite helpful in this case.

Do THC detox kits work for hair tests?

The hair test is different from urine test and methods to pass them vary. Generally speaking, a THC detox kit in the form of beverages or pills may not be suitable to pass a hair test. The reason is simple – for the purpose of a hair test, the lab technician obtains a sample of your hair to determine whether you’ve ingested THC within the last 90 days. Flushing out toxins through pee may not be the best route because they remain in follicles. Detox shampoo can be helpful, though. 

Detox products and methods to avoid

Methods to try for passing a drug test are numerous, but some of them should be avoided. They include:

  • Drinking way too much water (staying hydrated is important, but going overboard can dilute urine in an obvious manner)
  • Drinking undiluted bleach
  • Drinking vinegar
  • Drinking pickle juice

Tips and recommendations from social media

Social media is a rich source of recommendations regarding THC detox. Some of them include:

  • Consumption detox foods such as lemon, garlic, broccoli, grapefruit, mung beans
  • Intake of detox pills
  • Taking zinc
  • Intake of activated charcoal capsules
  • Abstinence 

Bottom line

Weed cleanse isn’t a mission impossible when you know what to do. This post showed you some interesting things you can try as well as methods to avoid. The choice is yours, but make sure to remember that the THC elimination rate depends on different factors and may vary from one person to another.
