How Long Does CBD Stay In Your System?

CBD, short for cannabidiol, has grown in popularity over the past couple of years, particularly as a supplement. However, because it contains trace amounts of THC, it’s still possible that it is detectable in drug tests or screenings.

In fact, recent research has shown that drug tests can’t tell the difference.

This can be particularly worrisome if you are searching for jobs or need to consent to drug screenings for other reasons (e.g., being on parole). It’s a common misconception that CBD and THC are the same; while CBD is a natural supplement, it’s still possible for the THC metabolites to be detected during drug screenings.

There isn’t a simple answer for how long CBD stays in your system. It depends on a number of factors, such as how it was administered, the dosage, and the frequency of use.

Let’s take a closer look at the different ways you can take CBD and how your body processes it. Then we’ll walk through how long it will stay in different systems of your body.

How Your Body Processes CBD and Factors That Affect How Long CBD Stays In Your System

There are many different factors to consider that influence how long CBD stays in your system as well as how it affects you. How long it lasts and is detectable is not the same for everyone. It can depend on:

  • Physical factors and genetics, such as your metabolism, age, and weight
  • Last time it was taken
  • Dosage
  • Frequency of use

CBD is fat-soluble, meaning it’s stored in your body’s fat cells rather than the water cells. Therefore, your Body Mass Index (BMI) influences how quickly it is metabolized. The higher your body mass and weight, the longer it will take to leave your system.

Your method of intake can influence how it affects you as well as for how long it lasts. Popular methods and forms of CBD include:

  • Oils
  • Vape
  • Dietary supplements
  • Edibles
  • Dried flower

If you smoke dried flower CBD or use a vape cartridge, the CBD enters your bloodstream within seconds. Therefore, brain effects associated with CBD occur the quickest in this manner.

If you take a dietary supplement or edible that contains CBD, the effects won’t be felt immediately. Your metabolism and diet can influence how soon you feel the effects. However, symptoms are often felt within an hour of digesting it.

Regardless of how you take it though, the effects can typically last between one to three hours.

But does the duration of its effects influence how long it stays in your system for?

How Long Does CBD Stay In Lab Tests?

Just because you no longer feel the effects of CBD doesn’t mean it is no longer detectable. The half-life of CBD is between 18 and 32 hours. However, it can be detectable on lab tests for much longer than that.

Most drug tests screen for THC, rather than CBD. THC is the main component of marijuana. However, as we mentioned, CBD contains trace amounts of THC.

If you pass a drug test after taking CBD, it doesn’t necessarily mean you have traces of THC in your system. It may just mean you’re below the detection level.

Different drug tests have different cut-off levels. Legally, hemp products can contain up to 0.3% of THC.

Furthermore, some tests are more effective at detecting THC and for longer periods of time. The type of drug screening you’re administered – and how long after you last took CBD – could influence whether it’s detectable.

It’s also worth noting that because CBD products are not regulated by the FDA, it’s possible that you could be taking CBD that is mixed with other cannabinoids, which could increase detectability. Also, it’s worth noting that the more frequently you use cannabis products, the wider detection windows become.

How Long Does CBD Stay In Your Urine?

Urine tests are the most popular and common method of drug screening for employers. The detection-window for THC through urine tests can vary widely.

It hinges mostly on the dose you took and your frequency of use. Typically, these metabolites can show up on a urine test anywhere between three days to two weeks after the last time taken.

According to the Mayo Clinic, THC metabolites can be detected for as long as 15 days post-administration among frequent and daily users. However, the research also suggests that these numbers can vary based on the dosage.

How Long Does CBD Stay In Your Hair?

Hair tests are known for being able to detect drugs for an extended period of time. These tests can detect the THC metabolites in CBD for as long as three months post-administration. However, hair tests are also very uncommon for THC and CBD.

How Long Does CBD Stay In Your Blood?

Although blood tests are not nearly as common as urine tests for screening for CBD and cannabinoids, they can be used to detect THC metabolites. The reason they’re not the preferred method of drug screening is because of how quickly THC is eliminated from your bloodstream.

Generally, THC is only detectable in your plasma for about five hours after you take it. However, THC metabolites and, therefore, CBD can be present for up to a week.

How Long Does CBD Stay In Your Saliva?

Similar to hair, saliva tests for CBD or THC are incredibly rare for employment or legal reasons. However, the drug components could be detected within minutes after you take it and could last for up to 36 hours, depending on the dosage and frequency of use.

If you consume CBD products in large amounts, and on a regular basis, it’s possible that this test – as well as the others – could detect it for longer.

Get Treated for Drug Addiction

If you’re trying to break free from the burden of cannabis addiction, know that it is possible. While some people may insist that you can’t become physically dependant on cannabis or cannabis-related products, psychological dependency can be just as disruptive.

For many people, making the decision to get help can be the hardest part. But you’ll be happy you did, and the sooner you take action, the better.

Does CBD Affect Blood Work?

We have good news on that front and we’ll also look at key questions around CBD’s duration in the body.

These are the areas we’ll cover:

  • Does CBD show up in a 10-panel drug test
  • Does CBD show up in routine blood work
  • Does CBD affect blood panel results
  • Does CBD affect kidney numbers
  • Does CBD affect liver panel
  • How long is CBD detectable in urine

Let’s get started.

Does CBD show up in a 10-panel drug test

The first question centers around failing a drug test.

We covered this in detail at our Can CBD make you fail a drug test but the quick answer is…

NO. With a very big caveat.

It has to be CBD isolate with ZERO THC. Lots of full spectrum products can cause you to fail a test since they may legally have .3% THC which can trigger the tests.

THC builds tolerance over time so we focus on isolate anyway for health purposes. See CBD versus THC to learn more.

CBD is not tested in drug panels. Its cousin, THC is. CBD and THC are almost opposite to each other in terms of how they work in the body.

CBD is not psychoactive in that it doesn’t produce a high.

It’s also not addictive (see CBD and addiction), doesn’t build tolerance (see CBD and tolerance), and doesn’t cause withdrawals (see CBD and withdrawals).

We have a more in-depth look at how they oppose each other at our why you must use CBD if you smoke cannabis.

Again, CBD is legal in all 50 states and is not tested on drug panels including the 10-panel drug test.

One note of caution. full spectrum CBD can have up to .03% THC.

This can build up and may make you fail a drug test!

That’s why we focus on CBD isolate. zero THC!

Also, we don’t like the baggage that THC brings with it.

What about routine blood work?

Does CBD show up in routine blood work

No. CBD should not show up in any blood panel work you may have.

First, it’s not tested specifically nor are any metabolites.

None of the tests have a breakout specifically for CBD since it’s not illegal and doesn’t impact other blood panel results.

The one condition is with other medications.

Let’s look at whether CBD affects the results of blood panels next.

Does CBD affect blood panel results

At standard doses (300 mg is the max for neurogenesis in research), the effects of CBD on blood panel results should be negligible.

Research has even looked at higher doses from 600-800 mg for more serious issues like schizophrenia or acute anxiety.

First, what does research show on the safety side where things might be measured?

We’ll start at the physiological level first and work our way down to blood:

The comprehensive review of 132 original studies by Bergamaschi et al. describes the safety profile of CBD, mentioning several properties: catalepsy is not induced and physiological parameters are not altered (heart rate, blood pressure, and body temperature).

As for mental, physical, and gut effects:

Moreover, psychological and psychomotor functions are not adversely affected. The same holds true for gastrointestinal transit, food intake, and the absence of toxicity for nontransformed cells.

Check out CBD and the gut to understand how it can help there.

Let’s drill down into the bloodwork now:

CBD treatment of up to 14 days (3–30 mg/kg b.w. i.p.) did not affect blood pressure, heart rate, body temperature, glucose levels, pH, pCO2, pO2, hematocrit, K+ or Na+ levels, gastrointestinal transit, emesis, or rectal temperature in a study with rodents

We have some key players of our blood panel work there:

  • Glucose
  • PH
  • CO2 and Oxygen
  • Hematocrit (red blood cell ratio)
  • Potassium and sodium
  • Gut function

One of the first tests looked at blood and urine tests specifically:

A first pilot study in healthy volunteers in 1973 by Mincis et al. administering 10 mg oral CBD for 21 days did not find any neurological and clinical changes (EEG; EKG).64 The same holds true for psychiatry and blood and urine examinations.

Another study followed up with 30 days of CBD use and found the same results.

Epilepsy patients were monitored for 135 days at 200-300 mg of CBD and the results were the same for blood panels:

Moreover, neurological and physiological examinations were performed, which neither showed signs of CBD toxicity nor severe side effects.

Let’s shift our focus to hormones.

Does CBD affect hormone levels

The endocannabinoid system (which CBD works within) is tasked with balancing three key systems including the endocrine system (hormones).

This is everything from metabolism, sleep, stress response, etc right to the steroidal hormones like estrogen, progesterone, and testosterone.

We did a big review of CBD and estrogen since it’s such a critical supporter of serotonin function (see CBD and serotonin).

CBD has been shown to affect these pathways but not in an abnormal way.

For example, CBD was shown to reduce resetin which is a hormone tied to obesity. (see CBD and weight during perimenopause or CBD and appetite).

We cannot find human studies of CBD affecting hormone profiles at doses common in research (300-600 mg).

THC has been shown to suppress the entire suite of steroidal hormones which has important ramifications.

Since CBD has shown opposing effects to THC in almost every pathway, we wouldn’t be surprised if it constrains THC’s effect there as well. We need more research.

Let’s look at the two workhorses for our urine and blood panels respectively.

Does CBD affect kidney numbers

It’s hard to separate out CBD from cannabis or THC in the studies.

There are studies where CBD is used to protect the kidney when under assault such as:

The cannabidiol treatment had a protective effect against inflammation and oxidative damage in the kidney ischemia/reperfusion model.

If standard kidney function as normal CBD doses (300-600 mg) was impaired, we would expect to see it in the urine panels above and we didn’t.

We look forward to more specific kidney testing. Always work with your doctor or naturopath for any supplement especially if you have kidney issues.

Does CBD affect liver panel

First, understand that the liver is the primary site of CBD metabolism.

In fact, it uses a very common thoroughfare called P450 that up to 60% of common medications also use.

For this reason, it can interact with other medications and this is why you should work with your doctor or naturopath if you’re on other medications with any supplement.

It can slow down or increase the absorption of the other medication.

There was a study on mice that showed potential liver issues from CBD but the doses given were so high (approximately 3200 mg for a 160 pound human) that it’s nonsensical.

You can die from too much water and Tylenol is the leading cause liver failure in the US. (see CBD versus tylenol or how CBD protects the gut from aspirin or NSAID use).

If standard doses had issues on the liver, we would see it in the blood panels referenced above in studies.

In fact, there’s evidence of CBD’s benefits for liver function when under duress.

Mice were given a poison essentially which would severely impact the liver and brain.

The effects of CBD:

Increased plasma levels of ammonia, bilirubin, and liver enzymes, as well as enhanced 5-HT levels in thioacetamide-treated mice, were normalized following cannabidiol administration.

The keyword there is “normalized”. Not boosted or reduced. We see this throughout other key pathways such as serotonin, GABA, and even cancer!

Some practical questions.

How long is CBD detectable in urine and blood

So. we already addressed that CBD will not cause you to fail a drug test or even show up on a drug test (if it’s CBD isolate).

How long does it show?

  • The peak level for CBD in the blood in about 4-6 hours.
  • The half-life is about 31 hours.
  • The elimination period was generally 3-5 days

As for the urine, CBD is generally expelled after about 3 days:

In the urine, unchanged CBD and, to a lesser extent, conjugated CBD were the main excretion products, and about 16% of the total radioactivity was eliminated in 72 h by this route of excretion.

Again, CBD is not part of the standard drug panel as long as it’s CBD isolate only (not full-spectrum which can have THC).

One caveat. this is all based on CBD isolate and quality product. which is NOT everything on the market.

For this reason, we follow these rules.

  • Organically grown hemp in the US at an FDA registered farm
  • CO2 processed
  • 3rd party tested (top of every page)
  • No THC!!
  • No solvents
  • No heavy metals
  • No pesticides
  • No bacteria
  • No mold

We actually test twice since our whole family uses it. Be well!
