How Long Does CBD Stay in Your System

How long does CBD last in your system once consumed? Well, your experience may vary based on a few factors, including the ways you consume it, a person's body weight, lifestyle, frequency, and the concentration of the dosage, related to one's body biochemistry.

You may be curious to know whether or not it will show up on employers' drug tests.

Generally, it can take about one full week for cannabidiol to fully metabolize within the human body enough to pass a substance test screening specifically for it. 

No matter which way you enjoy this cannabinoid, it should be completely free of the body within a week.

You may be wondering if cannabidiol will trigger a false-positive on a drug test. How long will cbd oil stay detectable within urine.

We will dive into each one of these topics below, but first, here is the short answer to this question.

Will you fail a drug test for THC with CBD products? No.

CBD isolate and broad-spectrum forms will not trigger a positive result on a drug screening. If you use a full spectrum product, there are traces of THC (<0.3%), but with a higher enough dose close to a drug screening, it could result in a false positive.

Scientists discovered that cannabidiol half-life within the blood is three to five days; however this result depends on the way it is consumed.

I hope that helps answer your question! Now that you know that dosage volume and frequency can affect drug screening results, you may also want to know the process cannabinoids undergo as the body metabolizes them, so you can better calculate the dosages for yourself.

How Long Does CBD Stay in Your System?

We'll start with a scientific approach. Researchers who have studied the half-life of cannabidiol claim that it takes an average of 4 days to clear from the system. 

A published 1991 research article found 14 Huntington's disease patients and measured cannabidiol blood concentration levels after high daily doses.

Over six weeks, the research team administered a daily dose of 700 milligrams of the cannabinoid to research participants. 

CBD metabolizes in roughly 1 week from consumption

One week after ending dosages, CBD levels remaining within the blood were at 1.5 nanograms per milliliter and "virtually undetectable" after that.

The same research showed cannabidiol half-life to be between 2 and 5 days.

The study further determined that patients who consumed 700 mg every day for six consecutive weeks expelled the cannabinoid from their bodies at relatively the same rate over the next seven days after ceasing oral ingestion. 

This research concluded that both men and women metabolize cannabinoids at about the same rate.

Even with these results, trace amounts of cannabidiol may remain within the body undetected. You'll need to consider that CBD clearance times are also affected by the volume, frequency of use, your age, weight and body chemistry.

Knowing how long the effects lasts depends on the ways you decide to consume it. There are many ways to take cannabis; just know that these methods will play a key role when determining a dosage schedule for you.

Also, be mindful that there is no way to determine 100% accurate dosages and durations for every person since everyone has an entirely different metabolism and lifestyle. Many variables may substantially affect a person's results.

Let's focus on the average person. It is best to experiment for yourself with low dosages and work up to an ideal dose based on how cannabidiol affects you.

CBD Tincture Dosing Chart

In a 2005 examination, researchers gave volunteers soft-gelatin capsules containing 2.5 milligrams of THC extract and 1.35 milligrams of CBD extract. The research team discovered that cannabidiol was only detectable within the blood for up to 6 hours after ingestion. 

These studies provide insights into the time it takes for cannabinoids to leave the blood, but there is little evidence pointing to how long CBD remains detectable within urine. 

In a published 2016 study, researchers administered CBD-rich cannabis products, including capsules, oils, and high-CBD flower, to a 15-subject control group. Two hours after researchers administered the control, 14 of the 15 participants tested positive for CBD and THC metabolites. The experimenters followed up with one participant after the last day and found that cannabidiol was no longer detectable after 24 hours after taking urine samples. 

However, according to an article published at the Mayo Clinic, a urine test may detect THC metabolites for 10-15 days for daily use cases.

Researchers are constantly studying cannabis as a more natural health alternative

CBD is a More Natural Health Supplement

We live during stressful times. People are getting sick, and the pharmaceutical industry surrounds us with many drugs promising relief.

Many of those drugs, however, come with side effects that are arguably worse than the ailment they claim to treat. So it is natural to look for a promising solution as with natural products derived from hemp.

Cannabis and many other natural remedies have existed on our planet for centuries. Now, it seems, humanity is open to natural healing and preventative medicines that they are more open to experimenting with the plant Mother Nature has bestowed upon us.

It has become incredibly popular as a health supplement providing many positive health and therapeutic effects as a safer alternative to opioids and synthetic painkillers as well.

CBD has been shown as an effective tool for managing inflammation and pain. Research has proven that the cannabinoid produces an analgesic effect when metabolized within the human body.

I am sure you have many questions about it, so we will explore all the variables that you'll want to know about before using CBD-specific products for yourself.

CBD vs. THC molecular structure

What is CBD Exactly?

Let's start with a short explanation of what cannabidiol is, so we can better understand the ways it interacts with our bodies.

Cannabidiol (CBD) oils are extracted from the hemp plant, and while it is also found in marijuana plants and cannabis with high THC concentrations, it lacks the psychoactive effects as with marijuana. We've written about it if you'd like to learn more about what cbd is in more detail.

Recently, the 2018 Farm Bill legalized hemp research and extracts for research as long as it meets specific guidelines put in place by the FDA. You can read more about that THC and CBD legalization here.

As long as it is extracted from hemp plants containing less than 0.3% THC, CBD is considered federally legal. Hemp naturally contains lower levels of psychoactive THC; therefore, it will not induce a high. You can supplement CBD oils into your daily regimen without the risk of impairing senses.

States have precautionary measures in place, so their laws may be vague within the individual states.

One of the first steps in normalizing positive cannabis use is to make a clear distinction, and show that CBD is not Marijuana. CBD should not share THC's stigmas in conversation. It has amazing therapeutic benefits and is improving the lives and mental health of millions of people all over the world while not producing the high.

The difference is in where high concentrations of CBD are found versus THC. Hemp contains higher CBD concentrations (20-27% CBD) and trace amounts of THC, which marijuana has higher THC concentrations (5-20% THC) and trace amounts of cannabidiol.

I will admit, however that when combined with THC, cannabis products provide a much better result than CBD on its own. This is due to a symbiotic relationship that cannabinoids share known as the "entourage effect."

The endocannabinoid system comprises of receptors that bind with cannabinoids

Want to know how it all works?

Well, to start, there are over 110 active compounds known as cannabinoids found in marijuana and cannabis. The human body has natural receptors for these cannabinoids known as the endocannabinoid system (ECS).

When cannabinoids naturally bind with these receptors found in the body, they produce a healing effect that helps restore the body's optimum functions.

This response assists with stress management, anxiety, convulsions, chronic pain, and many other symptoms; it helps to control appetite, sleep, mood, and body temperature. The endocannabinoid system regulates how cannabinoids interact with your body.

Because CBD triggers a number of these receptors, it helps contribute to healthy bodily functions as a useful remedy for many health issues. Its scope for healing grows every day as scientific studies continue to expand on it.

Factors That Influence CBD Metabolism

CBD is naturally a fat-soluble substance, but it affects people differently. There are a variety of factors that affect how long does cbd effects last within the body, but they also affect how quickly it leaves your body.

Cannabis metabolism is based on many factors

Let's take a look at these:

Method Of Consumption

One of the leading factors in determining how long CBD stays in your body is known as "bioavailability." Bioavailability, or the method(s) for how you consume it, lead to a drug's presence in your bloodstream.

There are many ways to ingest CBD from inhaling it through the lungs, to eating foods; from applying it to your skin to absorbing it sublingually under your tongue with tinctures and oils. We'll take a look at how each works.

How long does CBD oil last while Vaping?

The effects begin to appear within 5 to 10 minutes after vaping. Similar to how quickly it enters your body, it leaves your body quickly, too, usually within 1 to 4 hours.

Whether you're vaping from a CBD vape pen or smoking a high-CBD flower, your body responds in the same way. When you inhale CBD from a vape, cannabinoids are rapidly absorbed into and circulated throughout your bloodstream.

Due to how fast you'll feel CBD's effects after vaping, many people prefer this method over others, especially those who already smoke or vape nicotine products. Current evidence suggests that CBD reaches its peak in the blood within 3 minutes of inhaling it. As this method ensures fast relief, it also means the effects do not last very long. 

2007 study shows that CBD may appear for up to 72 hours after inhaling. 

Please research any inhalable products you plan to use to make sure the ingredients do not contain Vitamin E Acetate, which is an additive linked to the recent media scare. Consumers have been duped by illicit cartridges that have led to many people being hospitalized and a few deaths.

It is equally vital to point out that most vape products on the market are relatively safe (as safe as inhaling vapor can be). Vaping, as an alternative to smoking, has helped so many people who continue to struggle with smoking addiction.

If you are curious whether or not the CBD vape oil you love will show up on drug test, continue reading and we will explain it all below.

NOTE: Only use inhalables from manufacturers who provide 3rd party lab test results.

Gummies are the most common medicinal cannabis edible due to their small size and sweet taste.


CBD-infused edibles take longer to absorb into the body since they metabolize within the digestive system. The effects can be felt almost immediately on an empty stomach but can take up to 6 to 8 hours to fully digest.

Studies show that when the liver metabolizes CBD compounds, they undergo what is called the "first-pass effect." Enzymes undergo oxidation in the liver and reduce CBD concentration before the rest finally circulates throughout the body. 

While CBD edibles are popular among consumers for their ease of use, ingesting CBD is a somewhat inefficient method when compared to inhalation or sublingual methods.

NOTE: Only 5% of CBD remains in the bloodstream when swallowed (low bioavailability).

Sublingual tinctures are common ways to take cannabidiol

Sublingual Administration

Similar to other forms of edible CBD, placing drops under the tongue takes longer to absorb. Since this form requires the mucous membrane to absorb CBD, it also takes longer for CBD to exit your body when ingested this way (4 to 6 hours for a single dose).

Applying heat to your skin before using lotions and creams will ensure the best absorption.

Topical Application

Topical CBD is available in many forms. You can infuse it into creams lotions and salves. It mixes well with all sorts of wellness products because it can be applied directly to your skin, where it interacts with localized cannabinoid receptors beneath the surface. 

Massaging CBD into your skin takes a long time to absorb, and you may not feel the effects for a while.

In some instances, CBD-infused topicals should be applied liberally to overcome the skin's low cannabinoid absorption rate. Doing so will allow the CBD to pass through keratinocyte membranes, which are cells on the skin's outermost layer. 

It is not entirely clear on how long topical applications will take to enter your body or the time it takes for them to exit, but research suggests when CBD is applied topically to the skin, the CBD's permeability is ten times higher than THC, and peaks after 90 minutes.

Some brands like Mana Artisan Botanics™ also offer therapeutic creams and oils that can be applied directly to your skin.

It feels good and smells great!

NOTE: You are more likely to wash off topical CBD before it is fully absorbed into your body, so you can generally be more liberal with how much you use.

Body weight and BMI contribute to how quickly substances metabolize

Body Weight

Since CBD oil is fat-soluble, your body stores it within its fat cells. Just like any other substance that is metabolized with fat, the amount of fat in your body plays a role in how fast it will metabolize.

For example, people who perform a lot of exercises and burn fat faster have fewer fat cells in which to store CBD long-term. That means CBD will not take nearly as long to metabolize in an active person, versus someone who is not as active and has more fat cells to store it.

Existing research suggests that individuals with higher BMI that use CBD regularly may store excess amounts of CBD for longer durations within their bodies.

There are water-soluble variations as well, but these forms of CBD are usually cut with additives designed to make it water-soluble, which results in a less reliable lower bioavailability product.

Physical activities promote a healthy metabolism


As mentioned above, pure CBD oil is fat-soluble, so people with higher BMI will have a higher chance of retaining excessive amounts of CBD within their system. Similarly, people who perform activities to promote a higher metabolic rate are more likely to expel CBD from their systems more quickly.

People who consume a high-fiber diet are more likely to clear CBD from their bodies quickly versus a diet with lower levels of fiber.

Likewise, those who have a diet rich in vitamins and minerals, who tend to get better rest, who lead a healthy active lifestyle will have a higher metabolism. 

These individuals will, therefore, expel CBD faster than those living a sedentary lifestyle.

Frequency & Dosage

Another essential factor to consider involves how often CBD is consumed and at what concentrations. Since your body stores CBD in fat, when the body uses it wants to use, it stores the rest in fat cells.

For single-serving users, CBD may stay in the body for 2 to 3 days; for users with a moderate frequency, 3 to 5 days; repeated high doses may remain in your body for up to 2 weeks.

CBD metabolism also depends mostly on the concentration of each dose. Lower dosages clear faster than higher dosages, but the variables do not end here.

NOTE: If you consume more CBD than your body wants to use, it will save the excess in fatty tissues.


Everyone has different body biochemistry and will experience reactions to substances differently. Our endocannabinoid systems (ECS) also react to compounds differently from each other. This discrepancy can determine how long it may take for CBD to leave the body.

There is still much medical research that needs to be done, but there is no mistaking that your body's biochemical environment will impact how long it takes for compounds like CBD to clear your system.

How Long Does Cbd Oil Stay In Your System?

It is natural to assume that once the effects have worn off, so has the substance. However, even if you no longer feel the effects physically, that may not mean the compound has left your body entirely. It will gradually reduce over time and can be a slower process than you might think.

We discussed a few different factors that may contribute to how long CBD stays in your body. Consider these factors when making that determination for yourself. Experts posit that CBD takes a period of 3 to 4 days to clear your system completely, but this is a common assumption based on average factors.

Will CBD Appear On A Drug Test?

Whether or not CBD will appear on a drug test depends mostly on what type of CBD product you consume and the type of test a job requires upon employment. CBD products you consume may contain these trace amounts of THC no matter how much CBD oil you take if it is a full-spectrum.

THC content is not an issue if you choose a CBD isolate or broad-spectrum product, so you won't fail a drug test in this case.

As long as CBD products contain no more than a small trace amount of THC, you should not have to worry about failing a drug test.

The best way to ensure this is to examine the product's 3rd Party Lab Test results, which will show the exact amounts of each compound within the product.

Make sure these tests are updated periodically. It is not vital to understand all of the terms on the report. If you email the provider, they will be able to explain parts that are not as clear.

These tests ensure there are no additives, solvent residues, or pollutants within the product. It will also verify the presence and amount of THC and an accurate concentration of cannabinoids such as CBD. Use this information to help you determine how much of that particular CBD product you should take.

In most cases, for the average person, you would need to take an excessive dosage of full-spectrum CBD oil (1,000 to 2,000 mg) to risk testing positive and experiencing a failed drug test.

If you wish to be more cautious, choose a CBD product with no THC. Broad-spectrum CBD oil or products that contain a pure CBD isolate are best in this case. Most drug tests do not screen for CBD only.


CBD oil is well known for its health benefit claims. It can be used to treat physical pain, depression, arthritis, tremors, and PTSD. Since it will not come with any psychoactive side effects, you don't have to worry about feeling impaired at all after you consume it.

It is safe to incorporate into your life daily, but its concentration depends on your individual preferences. However if you use an inferior CBD product with mislabeled THC or do not check the third-party lab tests for it, then you run the risk of failing a drug test if you use CBD too close to the screening date.

The amount of time it takes for cannabidiol to leave the body depends on many factors we covered above, including your lifestyle and dosage frequency.

As with any substance you consume, remember most importantly to take the recommended dosage to avoid overdosing as taking too much CBD will reduce its effectiveness and cause it to take longer to leave your body.
