Cannabis Detox: Is There a Need for It?

There are many reasons you would want to detox from cannabis, regardless of whether you are finding benefits from consuming it.

Perhaps you have a drug test coming up for which you need to be 100% THC-free. Or maybe you are taking a tolerance break to optimize your cannabinoid intake goals.

Regardless of your reasons to do it, if you keep reading, you’ll learn what a cannabis detox is and how to perform one.

What Is a Cannabis Detox?

Cannabis detox is the process of cleansing the organism of any cannabinoids absorbed by the body. Most of the time, a cannabis detox will target THC, the main psychoactive component found in cannabis.

The body can detox from cannabis naturally simply by abstaining from consuming it, but a few things can be done to accelerate the process.

Unfortunately, there isn’t a standard for the amount of time a cannabis detox takes. The time frame is partly defined by the amount and frequency with which the person consumes cannabis.

Does Cannabis Detox Have Side Effects?

Depending on the frequency of consumption, the cannabinoids you are consuming, and the reasons why you’re consuming them, a detox may cause some side effects. The following are among the most common [6].

  1. Irritability
  2. Anxiety
  3. Restlessness
  4. Appetite Shifts

A debate exists on what these effects should be called; some claim these are withdrawal effects while others would explain them as the results of stopping the consumption of a therapeutic substance.


Cannabinoids can only be considered therapeutic if it is considered medically necessary. Which only happens in certain medical situations and states. In this, the appreciation of the effects of consumption or detox is subject to your location’s legal definition of cannabis.

How to Perform a Cannabis Detox for a Drug Test?

You’ll need to be very careful when making suggestions of how to perform a cannabis detox. There are many ‘methods’ out there that are bogus. In some cases, they can even be dangerous.

 How to Perform a Cannabis Detox for a Drug Test?

Your body is built to detox naturally. While there might be certain things you can do to speed up the process, we cannot say what those are with the research we have on hand, and the best cannabis detox method is to stop consuming it. If you don’t want to stop there, this is where you want to start.

The most effective way to flush the system of cannabinoids is by using natural methods like abstaining from consumption for up to 6-8 weeks. In some cases, the amount of time might be more or less.

An all-natural cannabis detox experience would include:

1. Abstinence

There is no detox without abstaining from consumption. It’s up to the individual to choose whether they quit consumption at once or progressively get to a point where they feel comfortable stopping entirely.

2. Regular Exercise

Exercising may help boost your metabolism. CBD and THC are also lipophilic molecules which means they are stored in fat, so the more exercise you do, the more likely you’ll be able to expel them from your system quickly [5]

Exercising can also provide feelings of ‘happiness,’ which would also make it easier to stop cannabis consumption if you consume it to reduce anxiety or depression [1,2].

3. Hydrating Often

Hydrating often is different from overhydration. Overhydrating may cause unwanted side effects and is potentially harmful. Hydrating often and adequately, on the other hand, may increase health and help the body expel unwanted toxins.

4. Following a Healthy Diet

Avoiding sodium, sugar, and fat is an excellent place to start at. Some foods may increase water retention and fat formation, which would make it harder for the body to expel cannabinoids and other toxins. Avoiding these foods and replacing them with healthier ones will help speed up your metabolism, which is your ultimate goal.

Similar to exercise, a healthier diet could help you feel happier [4]. For that reason, having a more nutritious diet could also reduce the need for cannabis or CBD consumption, depending on what your goals are for consuming them. 

5. Hydrate With Diuretics

A diuretic is a substance that promotes increased production of urine. All diuretics increase the excretion of water from the body through the kidneys. While you can find diuretic pills, you may also find diuretic drinks like teas and coffee. Since we don’t know your physical and medical status, we can’t suggest you drink diuretics safely, but if you can, it is a way to speed along the detox process.

6. Consider Mental Health

A diuretic is a substance that promotes increased production of urine. All diuretics increase the excretion of water from the body through the kidneys. While you can find diuretic pills, you may also find diuretic drinks like teas and coffee. Since we don’t know your physical and medical status, we can’t suggest you drink diuretics safely, but if you can, it is a way to speed along the detox process.

7. Detox Drinks, Detox Kits, & Other Products

There is a wide variety of detox products available in the market. We can’t recommend any of them precisely because we haven’t tested them, so we can’t assess their effectiveness accurately. We can say that there are many options out there, and it wouldn’t hurt to do a little digging.

How Long Does a Cannabis Detox Take?

Multiple tests can be done to scan for THC and other cannabinoids. The most common one is a urine test, but institutions may also choose to perform blood or hair tests.

The amount of time that CBD and THC remain in the system varies widely depending on consumption frequency and amount. In general terms, you can expect cannabinoids to be found for a more extended period after intake in blood and hair tests than they are in urine tests. The exact amount of time is impossible to determine without the evaluation of the consumer in question.

How Long Does a Cannabis Detox Take?

As you might assume from the discussion above, some of the variables that determine how long cannabinoids stay in your system are:

  1. Consumption Frequency
  2. Body Fat
  3. Metabolism Rate
  4. Diet
  5. Exercise Habits

Less consumption, lower body fat, higher metabolism, healthier diet, and more exercise will naturally bring the time frame down a notch. Working on these five objectives will help your body get rid of cannabinoids faster and more efficiently.


A cannabis detox is a process by which the body eliminates cannabinoids from the system. A cannabis detox can be performed naturally by abstaining from consuming cannabinoids, but the process may also be accelerated by doing a few different things. While a cannabis detox may have some side effects, the debate of whether these are withdrawal symptoms or simple avoidance of the benefits that cannabis can deliver is still very prevalent.

Doing a cannabis detox is a very simple task. By simply abstaining from cannabis intake the body may perform a detox naturally. Although there are a variety of actions that benefit the detox. How long a cannabis detox takes will depend mainly on the frequency and amount of consumption.

The knowledge around CBD and other cannabis-derived products is growing and constantly changing, as does their legal status. Hence, we recommend checking with your local authorities and a licensed physician prior to consumption.
