How to Detox from Weed

By Anthony Pellegrino Updated October 24th, 2022

As of 2022, medical marijuana has been legalized in 38 U.S. states along with the District of Columbia. However, many of these legislative bills do not mandate that certain employers must accommodate the use of medical marijuana. There are also several other instances where the use of medical marijuana is still prohibited, such as government jobs or ‘safety-sensitive‘ positions. In these cases, cannabis patients must, then, “detox” from weed.

But what does this really mean, and what does it entail?

Below, we’ll show you all the ways cannabis can be detected and common methods people use to attempt to detox from weed (including natural methods and products as well as marijuana detox kits).

What is a Marijuana Detox Kit?

When an unexpected drug test comes up, many cannabis users turn to marijuana detox kits.

The word detox is short for detoxification, which refers to any treatment meant to clear the body of a substance. In this case, marijuana detox involves the removal of cannabinoids (mainly THC) from the body.

Now, it must be mentioned that this language could be misleading. We aren’t saying that THC and other cannabinoids are toxic. A ‘weed detox’ is just referring to the removal of these cannabinoids. There are several ways to conduct a marijuana detox along with some specialized detox help speed up the process.

Why Would You Use a Weed Detox Kit?

Marijuana can remain in your system for days after use, and in some cases for weeks.

There are many reasons a medical patient may wish to detox from marijuana. As mentioned above, workplace drug tests are a big reason. Perhaps you are a legal medical patient in your state but have accepted a job offer in a workplace drug tests its employees. Your employer may request a drug test from you before you can formally receive an offer of employment.

But that’s not the only reason people detox. In some instances, the conditions for probation or parole mandate that parolees must abstain from using any substances, including weed. This can be a bad situation for a parolee that may need to pass a drug test.

And even people who don’t have any pressing need to detox do it sometimes just to increase the effectiveness and lower their needed dose. This is very common for pain patients who often use large amounts of THC to control pain and develop a tolerance such as for conditions like Crohns Disease or to manage pain associated with cancer.

To be clear, if you or someone you know is on parole, the only safe way to pass a weed test is to not smoke weed. Everyone metabolizes cannabis differently, and a product or technique that works for one person may not work for others.

Abstinence is the only safe and sure way to pass a drug test.

What Are the Symptoms of a Cannabis Detox?

Irritability is a common, but usually mild symptom of cannabis withdrawal.

It is, in fact, possible to feel some symptoms from your marijuana detox in the form of withdrawal. While not as serious as withdrawal symptoms from substances like alcohol or benzodiazepines, many people report:

  • a change in mood,
  • diminished appetite,
  • irritability,
  • the craving of additional marijuana,
  • sleep difficulties,
  • and more when they detox from marijuana.

The level of severity of these symptoms depends on your personal physiology along with your level of use. The more you’ve used marijuana, the more your brain has gotten used to the supply of THC. When the THC leaves your system, with no resupply in sight, you may feel some of these symptoms of marijuana withdrawal.

How long does THC stay in your system?

So, how long does it actually take to get THC out of your system? The question isn’t so simple. THC and other cannabinoids settle in different areas of the body for different periods. Not only that, but THC may break down into several THC metabolites that remain detectable for far longer than THC alone.

Generally speaking, THC-COOC is the metabolite that is measured in many different drug tests, and often remains in the body for nearly 2-3x longer than THC itself. Yet, at the end of the day, the question of how long THC lasts in your system depends on your particular level of marijuana use.

How Long is THC Detected in Hair?

It’s often been said that THC is stored the longest in the hair follicles. However, recent research has shown that detecting THC in hair samples is not a reliable way to measure marijuana consumption. In some instances, no THC was detected at all in subjects who’ve consumed THC every day for the past month. In others, THC was found after a single-use.

Sometimes, being around someone else who is smoking marijuana can be enough. Nevertheless, hair follicle tests are the drug tests with the widest windows of detection. Some tests can detect THC and THC-COOC for as long as 90 days after using marijuana. 

How Long Can THC Be Detected in Blood?

The earliest THC can be detected in the body is via your bloodstream. It’s been shown that it only takes a few seconds for cannabinoids to enter your blood, where it lasts for several minutes. Nonetheless, most drug tests can only detect THC in blood samples for a few hours. THC-COOC, on the other hand, can be detected in the bloodstream for several weeks, especially with frequent or heavy use.

How Long Can Marijuana Be Detected in Urine?

Urine tests are the most common method of detecting marijuana.

In the vast majority of cases, marijuana patients will be using urine-based drug tests for the detection of weed usage. THC-COOC remains detectable for approximately 10 days after your last use. Yet, THC-COOC may remain in the urine of heavy and chronic users for up to 30 days.

Saliva Marijuana Test Detection Times

THC and its metabolites can also be detected in the saliva. However, THC will normally not remain detectable for more than 2-3 days in most users. At most, it can be detected up to a few weeks in very heavy users.

Ultimately, THC itself does not remain in any area of the body for long. But, its metabolite THC-COOC can remain detectable for several weeks at a time. Therefore, if you have a drug test coming up, it may be best to abstain or detox from cannabis for 6-8 weeks to allow all of the THC and its metabolites to exit your system.

Now that you know how long cannabis can be detected by the different types of tests, here are several of the most commonly used methods to cleanse THC from the body.

Natural Marijuana Detox Methods

While there are commercial products that can help you detox from cannabis (we’ll get to those in a minute), it’s also possible — and easy — to detox naturally. But how do you do it?

Abstaining to Detox from Weed

First and foremost, abstaining from any further marijuana use is crucial to detox from weed. After all, it can’t ever leave the body if it’s continually being resupplied, right? Step one of the natural detox is to stop using marijuana. After all, it can’t ever leave the body if it’s continually being resupplied, right?

Exercising to Detox from Cannabis

As we previously mentioned, THC, and its metabolites, have a fairly large range it takes to leave the body. But, you can increase the speed of your detox with the help of exercise. By and large, THC is stored in the fat cells of your body. Exercise, especially fat-burning cardio, will help burn all that THC out of the body. Exercise can also increase the rate of your metabolism, which is naturally responsible for the removal of THC anyway.

Drink Water to Flush Weed

The most popular way of detoxing from THC is boosting your water intake. Nearly a third of the THC in your system is flushed out via urine, and increasing your water intake obviously increases your need to pee.

Drink Tea to Detox from Cannabis

Many teas are rich in antioxidants and colon cleansers. As such, drinking lots of these teas can help spur your body to speed up the detox process. Some of the best kinds of these teas include ingredients like dandelion root, milk thistle, juniper berry, peppermint leaf, and Chinese Skullcap.

And when you decide to begin consuming cannabis again, you can bookend your detox with these cannabis tea recipes.

Maintain a Healthy Diet

A natural consequence of a healthy diet is a healthy and productive metabolism. Your metabolism is what is responsible for expelling THC and its metabolites from the body. Therefore, a healthy diet is the best natural marijuana detox. Not only that, but a healthy diet includes lots of fiber, which is necessary for regular bowel movements, which, believe it or not, is responsible for the removal of 2/3s of the THC in the body.

Marijuana Detox Products

There are some less natural ways to detox from marijuana, but their effectiveness is not universal. Anecdotal evidence suggests that whether the project works is a bit of a crap shoot. Still, some feel they are worth a try in a desperate situation.

Detox Kits for Marijuana

There are several products out there that are meant to help speed up the detox process. Generally speaking, detox kits contain ingredients that claim to cause changes to the body. These may include:

  • increasing the activity of enzymes,
  • boosting the pH of urine, or
  • breaking down chemical bonds in THC metabolites.

Each of which helps to rid your system of THC faster.

There are many brands of detox kits around today, and can mostly be found for sale online.

However, detox kits can be very expensive, sometimes running several hundreds of dollars, and there is no guarantee that they will work for you. That’s not to say that they never work. But, the products themselves are unregulated, and a consumer would have no legal recourse if they do not have the marketed effect.

Also, being unregulated, there isn’t any oversight into what’s actually in them. This can mean consumers ingest potentially dangerous substances as a result. Not to mention the fact that they may even be illegal to use at all, as their use may constitute ‘cheating’ a drug test. This can be a criminal offense in some states. The end result of this is that little research goes into detox kits or their health claims.

As a result, we encourage anyone who must detox from cannabis to use the natural methods listed earlier, focusing primarily on abstaining from cannabis use for 6-8 weeks prior to an expected drug test.

Detox Drinks for Marijuana

Detox drinks are similar to detox kits. Yet, detox drinks claim to provide rapid cleansing, with THC being removed from the body the day of their use. Each brand may have a different set of ingredients, but they’re all designed to immediately speed up your digestive system, metabolism, and need to urinate.

Detox drinks for marijuana can cost anywhere from $15 to $60 per bottle. Like detox kits, these drinks are not FDA approved for their intended use, nor are they regulated or guaranteed to work.

However, some of them do appear to work as advertised, as evidenced by this Vice article.

While the benefits of a working detox drink are the prompt removal of detectable THC from your system, they can result in distressing symptoms, especially for medical cannabis patients with sensitive immune systems. Many people report nausea, serious digestive problems, or discomfort following their consumption of detox drinks. After all, these drinks are meant to flush your system in an incredibly short period, and this will put an enormous amount of pressure on your metabolism.

Like the detox kits, the use of detox drinks can also be illegal if they’re meant to ‘cheat’ a drug test. Be sure to read up on your local laws regarding drug testing before using detox drinks.

Bentonite Clay

Bentonite clay has long been used for its absorbent qualities. It can be used to absorb oils on the skin and has been prescribed as a laxative of sorts. As such, some people ingest bentonite clay to help spur digestion and absorb some of the THC, among other things, in the body.

The FDA does not regulate bentonite clay. Given the fact that it’s a natural product, the greatest risk involved is a contaminated product. In the past, there have been some problems with certain brands containing unsafe levels of lead. As such, we don’t recommend medical marijuana patients use bentonite clay as a detox method.


There are many reasons you’d want to detox from marijuana. Whether you have a drug test coming up or are just looking to cut back, it’s a fairly common practice. However, given the risks detox kits and drinks can present, particularly for medical marijuana patients, we recommend sticking to natural detox methods only — with a focus on abstaining from cannabis use for 6-8 weeks.

It’s also very important to remember that some states have employment protections for medical marijuana patients, so detoxing may not be necessary. If you don’t have a medical marijuana card and think you may qualify for one, you can find out whether you qualify with a no-risk NuggMD consultation.
