How Long Does CBD Stay In Your System?

Table of Contents

As CBD continues to rise in popularity, more and more people are beginning to try CBD for its potential health benefits. That said, people sometimes confuse CBD with THC and wonder “how long does CBD stay in your system?”

Since CBD is somewhat similar to THC or tetrahydrocannabinol, some people throughout their CBD journey are worried about CBD showing up in a drug test.

Let’s get started.

TL;DR – CBD can stay in your system, in trace amounts, for several weeks. That said, CBD begins to break down roughly 24 hours after consuming it.

How Long Does CBD Stay In Your System?

Typically, CBD can stay in your system for approximately 8 to 12 days. Keep in mind this duration varies from person to person.

How long CBD remains detectable in the body depends on several factors such as metabolism and body composition.

After four to five half-lives have passed, the plasma levels of a drug (CBD) will be below a clinically relevant concentration and will be considered eliminated (Jericho Hallare & Valerie Gerriets, 2020).

  • Metabolism: the user’s metabolism plays a vital role in figuring out CBD levels in the body. How long CBD stays in your system also depends on how you consume it: are you taking the CBD on an empty stomach or after a meal?
  • Usage Routine: the more doses of CBD you consume, the longer it will stay in your body. That makes sense, right?
  • CBD Dosage: the more CBD you take per dose, the more CBD will be available in your body.

Cannabidiol and the Body

CBD is a plant chemical found in the cannabis plant. People use it for different health benefits. CBD oil is generally considered safe due to its non-psychoactive properties and lack of side effects, but few people may feel hesitant to use it due to its cannabis origin.

People associate cannabis compounds with testing for THC, which makes sense. We can see how people would be worried about that, but should they be?

Remember, CBD oil doesn’t get the user high as THC does. Whether you use CBD isolate or a different spectrum, it’s not going to get you high. It’s not possible.

How long CBD stays in the system depends on several factors such as body type, body composition (amount of fat content), the method of consuming CBD, and the user’s metabolism.

How Long Do The Effects of CBD Last in the Body?

Most people report they can feel the effects of CBD last for 4-6 hours, on average. In order to determine the length of time the effects from something can be felt, you have to determine the half-life, or time it takes something to degrade.

According to Epilepsy Current, “Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.

That means that it takes roughly two days for the dose of CBD to degrade by half. It takes approximately four to six complete terms to disappear completely.

If we took the 2-day time frame of CBD, it could take anywhere from eight to twelve days to get out of our body completely (2 days x by 4 or 6).

How Long Does Full Spectrum CBD Stay in Your System?

Most people have learned about the possible therapeutic effects of this non-intoxicating compound. Did you know there is both a broad spectrum and full spectrum version of it, though? The full spectrum version contains THC, so how long would the full spectrum stay in your system?

CBD and THC are both very, very similar on a molecular level. They also both interact with CB receptors found throughout the body. For this reason, we should look at both compounds.

Cbd Vs Thc

Cannabis contains two major species: hemp and marijuana.

What are the main differences between these two species? Hemp is very high in CBD, while marijuana is very high in THC. For this reason, all legal CBD products come from hemp, while controlled THC products will come from marijuana.

Different Cannabis Leaf Structures

CBD and THC are primarily found within the flowers, leaves, and stalks of their respective plants. Industrial hemp contains a large amount of CBD, and it’s why the hemp plant is used to extract CBD to make CBD oil products.

While the flowers of both plants might look almost identical, their cannabinoid makeup is quite different.

Full spectrum CBD stays in your system for roughly the same amount of time as THC (3-4 weeks) because of their acute similarities. Our bodies store and process these cannabinoids, making CBD detectable just like THC.

What Is THC (Tetrahydrocannabinol)?

THC is the psychoactive compound located within cannabis that people use for several different reasons.

Cbd Vs Thc

When you ingest or smoke products with a high level of THC in them, you get “high.” Some people like this feeling, others don’t. THC has many medical benefits, and a lot of cancer patients use it (in the form of smokable or edible marijuana) to help numb their pain and stimulate their appetite.

How Long Can CBD Stay in Your System – Different Types

The effects and presence of CBD in the body somewhat depend on how CBD enters the body and bloodstream. There are different types of CBD, and how long CBD stays in your system can also depend on the different types you use.

CBD ingestion can take 1-2 hours to start showing effects. When we eat substances, they also have to pass through the liver and kidneys before getting into our bloodstream.

Different methods of consumption have a different effect on our systems. When something enters your bloodstream, it becomes available for use, and different methods make it available at different speeds.

How Long For CBD Oil to Clear Your System?

Ingestion (by way of eating or drinking), or simply swallowed CBD, is a convenient and maybe the most common method of consuming CBD.

Hemp Oil And Cbd Oil

You can expect the effects of CBD to clear your body within several hours, but to clear your system completely it will take several weeks (3-4 weeks, on average).

The Sublingual Vein

The sublingual CBD consumption method is much more effective than ingestion. People place a few drops under the tongue and hold it there for up to two minutes. That’s it!

CBD reaches the bloodstream at higher levels because the CBD can enter the bloodstream via the sublingual vein. The time that it would take to pass through the liver is eliminated.

Some of the best effects of New Phase Blends exclusive products come from sublingual use.

Does CBD Oil Get into the Bloodstream?

Yes, it does. The reason we feel the effects of CBD is because it can get into the bloodstream.

When you use CBD products, the CBD is broken down into tiny parts. These parts are sent to the bloodstream, where they are circulated throughout the body and start to interact with the endocannabinoid system.

How Long Does CBD Stay in Your Blood?

CBD does not show up in normal, common blood tests that people take. If you blood test for cannabis, it is the THC metabolites they will look for. That said, traces of CBD can stay in your blood for months.

How Long Does CBD Flower Stay in Your System?

Inhaling CBD products, like CBD flower or vapes, is also an effective method of consuming CBD. Inhalation causes rapid absorption of CBD to the bloodstream, increasing bioavailability. Keep in mind, CBD vapes can cause health issues.

*Due to the nature of smoking and the recent vaping crisis, New Phase Blends chooses not to sell any smokable CBD or vape products.

How Long Does CBD Cream Stay in Your System?

Several CBD infused products are available in topical forms, such as lotions, creams, balms, salves, and gels which can be applied directly to the skin. Topical CBD is extremely popular.

Interesting fact: We have CB1 and CB2 receptors in our skin that respond to cannabinoid use, like CBD topical creams.

Take a look at this picture below from a well respected medical journal:

Our skin can absorb the CBD, and then transfer it to our bloodstream. Bioavailability is nominal with this method.

How Do You Clear Your System of CBD?

If you take 32mg of CBD oil, in 24 hours your body will have 16mg left. Another 24 hours past that, you will have 8mg. This halving is done until there is essentially no detectable amount left in your body.

While the CBD may be out of your body within several days (depending on how much you took), the metabolites that process the CBD will be stored for weeks, potentially. So while you won’t have any pure CBD molecules hanging around, you’ll have the residual metabolites.

This breakdown also depends on your body composition. For example, if you use a full spectrum CBD tincture, the CBD is stored in the fat cells (just like THC).

Cbd Softgels

People who have a larger body mass index, or BMI, and more fat, will store more CBD. This reduces the time it takes to break down the CBD within your body.

As a very general rule of thumb, the more fat you have on your body, the longer it will take to completely degrade all of the CBD you have stored in these fat cells.

Drug Testing and CBD: How Long CBD Lasts

The purpose of most drug tests is to identify the amount of a drug in our system. Drug tests screen for THC, not CBD. Typically, CBD won’t show on a drug test, but THC definitely will.

Many of the CBD products contain a trace amount of THC, which would theoretically cause a positive THC test result – because it is still detectable in urine tests. However, the amount of THC in legal CBD products is so minuscule that drug tests for THC will not show as positive.

How Long Does CBD Stay in Urine?

Urine tests for CBD are extremely hard to find, and quite expensive. Employers normally wouldn’t have a need to test for CBD. If you can actually find a urine test for CBD, expect it to stay in your urine for about 2-4 weeks. Keep in mind, urine tests are not very accurate.

The following drug tests are far more accurate, and may show even minute amounts of THC:

  • saliva tests
  • hair tests
  • blood tests

It is crucial to avoid any false positives for THC on a drug test by ensuring the CBD product is derived from hemp and not marijuana.

Marijuana derived CBD, on the other hand, can have much higher levels of THC. Some Marijuana-derived CBD products have THC content in excess of 20%. That is more than enough to show as positive on a drug test.

How Long Does CBD Stay Active Within You?

CBD can stay active for several hours. People typically report that they feel the CBD remain active for 3-6 hours, depending on the type of CBD they use. For example, some people swear that they can feel a full spectrum longer than a broad spectrum, and vice versa.

There really is no evidence to support either of these claims, though.

If consuming even slight amounts of THC worries you, stick to either broad-spectrum CBD or CBD isolate products. While full spectrum CBD products also contain hardly and THC, they still can contain up to 0.3% of THC, legally.

On the other hand, broad-spectrum CBD products and CBD isolate usually contain virtually no THC.

How Long Does it Take CBD to Leave Your System?

For a healthy, middle aged adult that exercises regularly, it can take about 3 weeks to clear your body of traceable amounts of CBD.

The higher your fat content, the slower your metabolism, and the more CBD you consumed, can all add time to this estimate.

Summary – How Long Does CBD Stay in Your Body?

So what’s the answer? After looking at all of the research in this article, I can safely say that in most cases, CBD will remain in some amount within the human body for anywhere from 8 to 12 days after use. Some people will have it eliminated from their bodies quicker, and others longer. Remember, it all depends on the following factors…

  • Metabolism
  • Body Composition
  • Method of Consumption

Since CBD is molecularly very similar to THC, it can cause a false positive in poor quality tests. You can also potentially test positive for THC since it might be in your CBD products in trace amounts.
