Research shows consuming cannabidiol (CBD) may have a host of potential health benefits, such as reducing anxiety, relieving pain, and promoting sleep—explaining the latest surge in CBD’s popularity. But people who use CBD—either regularly or just once in a while—might wonder how long it stays in your system.
No matter how you take CBD, it’s likely that the clinical impact can last for several days after use, says Kelly Johnson-Arbor, M.D., a triple-board certified medical toxicologist and co-medical director of National Capital Poison Center. In fact, a 2020 study in the Journal of Analytical Toxicology found people who consumed a single dose of a standardized CBD formulation had detectable levels of CBD in their urine for four to five days after ingestion  Spindle T, Cone E, Kuntz D, Mitchell J, Bigelow G, Flegl R, Vandrey R. Urinary Pharmacokinetic Profile of Cannabinoids Following Administration of Vaporized and Oral Cannabidiol and Vaporized CBD-Dominant Cannabis. Journal of Analytical Toxicology. 2020;44(2):109-125. .

5 Factors That Affect How Long CBD Stays in Your System
According to Dr. Johnson-Arbor, how long CBD stays in your system can depend on various factors.
How and What You Eat
How much you eat, as well as what you eat, can impact how your body processes CBD, says Dr. Johnson-Arbor. After consuming a high-fat meal, higher levels of CBD are typically present in the bloodstream, making its half-life (the time it takes for half the amount of a substance to be eliminated from the body) longer than in individuals who consume CBD while fasting, she explains. In other words, if you consume CBD on an empty stomach and don’t eat immediately, CBD is more likely to leave your system sooner. Meanwhile, eating high-fat foods, such as avocados, cheese and nuts, can have the opposite effect. One 2019 study also found CBD exposure and absorption increases significantly when paired with high-fat foods  Birnbaum A, Karanam A, Marino S, Barkley C, Remmel R, Roslawski M, Gramling-Aden M, Leppik I. Food Effect on Pharmacokinetics of Cannabidiol Oral Capsules in Adult Patients with Refractory Epilepsy. Epilepsia. 2019;60(8):1586-1592. .
Medications Processed in the Liver and Liver Disease
Certain medical conditions may impact how long CBD stays in your system. “Since CBD is metabolized by the liver, people with liver disease or who take other medications that are metabolized by the liver may have altered metabolism of CBD,” says Dr. Johnson-Arbor. She explains that the human liver contains enzymes that help the body break down medications and other compounds, and some medications can increase or decrease the activity of these enzymes. “When this happens, medications can be metabolized either faster or slower than normal, and this can lead to unwanted adverse reactions,” she says. Since CBD is metabolized by liver enzymes, there can be a potential drug interaction with many other medications.
Frequency of Use
If you use CBD frequently, it can build up over time and stay in your system longer, largely because CBD is highly soluble in fat. “This means that it can build up in our fatty tissues for a long period of time after heavy use and can therefore remain in the system for prolonged periods of time (e.g. weeks) in heavy users,” says Dr. Johnson-Arbor.
How Much You Use
Unsurprisingly, the more CBD you take at once, the longer it stays in your system. A 2005 study in the journal Therapeutic Drug Monitoring found taking 1.35 milligrams of CBD was only detectable in the blood for about six hours after ingestion, but higher doses were detectable for longer periods of time  Nadulski T, Pragst F, Weinberg G, Roser P, Schnelle M, Fronk E, Stadelmann A. Randomized, double-blind, placebo-controlled study about the effects of cannabidiol (CBD) on the pharmacokinetics of Delta9-tetrahydrocannabinol (THC) after oral application of THC versus standardized cannabis extract. Therapeutic Drug Monitoring. 2005;27(6):799-810. .
Type of CBD Administration
The way in which you consume CBD can impact how long it stays in your system. According to a 2018 review, smoking or inhaling CBD not only causes CBD to enter the bloodstream faster but also leave the body quicker. Meanwhile, the same review found CBD oil can stay in your system longer—up to two to five days. Dr. Johnson-Arbor explains that the reason smoking or inhaling drugs leads to faster clinical effects than consuming a drug orally is because orally administered drugs have to be absorbed through the gastrointestinal tract, and that takes more time. However, whenever you’re talking about how long CBD can stay in your system, it’s important to remember that it really depends on the frequency of use. “CBD (and other cannabinoids) are fat soluble, which means that they can accumulate in fat tissue after chronic use and then be released back slowly into the blood for elimination from the body,” she says. “This means that chronic users may have longer detection times than acute or one-time users (the latter is what’s generally represented in clinical studies and may not be applicable to the general population). The same is true for smoking and inhaling CBD. I don’t want people to get the wrong impression and believe that no matter how much or how frequently they use, CBD will only be detectable in their system for two to five days.”
How Long Do the Effects of CBD Oil Last?
How long the effects of CBD last varies greatly depending on the factors discussed above. “In a study involving healthy individuals who consumed a highly purified CBD formulation, the elimination half-life in the bloodstream was 14 to 17 hours. Since it takes approximately five half-lives to completely eliminate a drug from the human body, it’s likely that CBD stays in the system for about 85 hours, or about 3.5 days” says Dr. Johnson-Arbor.
So, based on the half-life of the drug, it’s likely that detectable levels may be present for several days after use.
How Long Does CBD Stay in Your System?
There are several reasons why a person may ask this question.
Perhaps you have an incoming drug test at work and are worried if they will test you for THC alone or THC and CBD combined.
Or, you’re just interested in the biochemistry of CBD and how it can affect you over time.
Regardless of your motivation, we’d like to answer your question.
This article will clear up any confusion about the time CBD may last in your system on top of explaining the onset time of different consumption methods and the duration of CBD effects.
How Long Should I Have to Wait for CBD Oil to Work?
Some people report the first effects within minutes after consuming CBD, whereas for others, it may take up to an hour until they can feel the difference.
Where does that disparity come from?
That’s because CBD has a different onset depending on how you consume it.
Below we outline the most common forms of CBD and compare the time required for the effects to kick in.
Sublingual CBD (Oil Drops, Tinctures)
Sublingual CBD, such as CBD oil or tinctures, act relatively fast. When using those, you squeeze out the desired amount of oil with a glass dropper and apply it under the tongue. Once there, you hold it for up to 90 seconds, and swallow.
The oil gets absorbed through a complex network of blood vessels that transfer CBD into the bloodstream allowing it to avoid the digestive system. Usually, the effects of sublingual CBD come within 15–20 minutes after administration.
Topical CBD (Creams, Lotions, Balms)
CBD creams and gels have made big headlines in the skincare market thanks to their effectiveness in relieving inflammation, pain, and revitalizing the skin. It’s a smart way to deliver CBD into your system without ingesting it directly. Topicals are applied to the specific area of the skin to help the user fight localized problems. When you rub CBD into the skin, it engages with CB2 cannabinoid receptors in its deeper layers, providing a range of therapeutic effects. This method requires CBD to pass through the pores to reach your system. The onset of their effects may vary from 10 to 90 minutes depending on the user.
Oral CBD (Capsules, Edibles)
CBD capsules offer an easy and convenient way to take your daily dose of cannabidiol. If you’re not into encapsulated supplements, you can also try CBD edibles, which are the new trend on the market — especially the gummies. Not only that, but CBD can be infused into shakes, cookies, dressings, or even pet treats.
Edibles and capsules are taken orally, meaning they need to pass through the digestive system before they can enter the bloodstream. Therefore, this form of CBD has a delayed onset. The effects may come in 20 minutes, but the waiting time can get as long as 90 minutes depending on your weight, metabolism, and whether you take CBD along with a meal or on an empty stomach.
Vaporized CBD (Hemp Flower, CBD Vape Oil, Concentrates)
Vaporization is by far the most efficient way to consume CBD. It combines the quickest onset with the highest amount of CBD that gets delivered to your system. You can experience the effects of vaporized CBD within minutes after inhalation; CBD vapes also have the highest bioavailability of all consumption methods, ensuring that up to 56% of the inhaled content makes it to the bloodstream.
CBD vape products include E-liquid (vape oil), concentrates, and hemp flower, which is a THC-free version of cannabis buds that you can roll into joints or consume in a dry herb vaporizer.
How Long Do the Effects of CBD Last?
Now that we’ve established how long it takes for CBD to take effect, let’s take a look at their duration. Of course, this will depend on a number of factors, such as your unique body chemistry, weight, age, gender, metabolism, as well as the size of the dose and consumption method.
Long story short, the more CBD you take, the longer the effects should last. However, there is no one-size-fits-all pattern for figuring out how long each person will experience them.
You can always experiment with different doses of CBD to see how your body responds to them, and how long it will take for the effects to dissipate. We suggest that you start around 2–5 mg per serving, which is considered a small amount. From there, you can monitor the effects and observe your reaction until you reach the point where you start to feel better.
CBD is well tolerated in humans, even in very large doses like 1,500 mg daily. That being said, we encourage you to use it responsibly if you don’t want to experience some minor side effects, such as dry mouth, sedation, or diarrhea.
Generally speaking, the effects of CBD can linger anywhere between 1 and 10 hours depending on the above factors.
How Long Does CBD Oil Stay in Your System?
This one is actually a bit confusing. The time CBD stays in one’s system varies from person to person and is driven by a number of factors.
The potency of your CBD oil, the amount of CBD taken, or personal traits like your gender, weight, age, overall health, and even the amount of water you consume daily — all of them can determine how long CBD stays in your system.
If you use CBD from time to time, your body should remove its metabolites in less than 7 days.
But what if you’re a regular user? How long will CBD stay in your system?
Here’s the Answer: We Don’t Know Precisely Yet
Research on cannabis has made tremendous progress since the past decade, but the truth is that we haven’t always had access to CBD oil that we know it today. Therefore, we still need more studies about the time CBD will last in one’s system. Experts in cannabis science don’t know it yet.
That being said, there have been a few studies that looked into the time CBD can stay in our bodies.
How Long Will CBD Stay in Your System? Here’s What Some Studies Say
A study that examined people who took 700 mg of CBD every day for six weeks has found that after the 6-week period, blood plasma CBD levels reached just 1.5 ng/mL on average among the 15 participants in the first week following the end of their therapy. After the first week, the research team concluded that CBD levels were “virtually nonexistent.”
Another paper on how long CBD can stay in one’s system comes from a 2014 study published in the journal Epilepsy Currents. The authors of the study stated that the half-life of CBD after a single dose applied orally lasts up to 2 days.
According to the University of Nottingham School of Health Sciences, the half-life of an active substance is defined by the “period of time required for the concentration [of the substance] in the body to be reduced by one-half.”
So, let’s say you take 20 mg of oral CBD. After 1-2 days, you would have approximately 10 mg of CBD in your system.
Sounds simple, right?
A growing number of studies suggest that drugs reach their “standby state”, which is the point where they can be effectively flushed from the body, after 4-5 half-life cycles. This would imply that you could use a simple calculation to determine how long CBD will stay in your system. However, the math gets complicated when you consider factors like the bioavailability of CBD or the administration route.
In a 2012 study published in the Journal Pharmaceuticals, the authors claimed that CBD actually had a longer half-life in humans than in animals. The duration is estimated to be between 18 and 33 hours for intravenous administration, between 27 and 36 hours for inhalation, and between 2 to 5 days for oral forms of CBD.
To sum up, CBD oil can stay in your system for anywhere between 4 and 25 days. While we admit this is a huge span, it’s currently the most accurate estimate scientists have come up with so far.
Does CBD with 0.3% THC Show Up On a Drug Test?
As mentioned earlier in the article, there’s a common misconception that CBD could show up on a drug test.
In fact, drug tests have nothing to do with CBD. They only look for THC metabolites in your system.
Not if it’s made from pure CBD or full-spectrum hemp that contains less than 0.3% of THC. CBD can be extracted from hemp and marijuana, so it’s important that you know the source of your CBD oil. Marijuana-derived products contain a significant amount of THC; they can get you high and are legal only in places that allow marijuana for recreational or medical use. Marijuana will also show up on a drug screening.
Hemp products are legal in all 50 states and shouldn’t result in a positive result for THC — as long as they were tested in a third-party laboratory for their CBD content.
Summing it Up: How Long Does CBD Stay In Your System?
We have no accurate resources to give you a definite answer to how long CBD stays in your system. It depends on how you apply the CBD, how much you take it, and how your body processes cannabinoids. However, most of the time, CBD should be gone out of your body no later than 7 days after the last application. Remember that CBD doesn’t appear on a drug test, so you don’t need to abstain from taking it for the sake of saving your career. As long as your CBD oil doesn’t come from marijuana, you’re safe.

How Long Does CBD Stay In Your System?
As with everything you ingest, especially when it comes to active ingredients in supplements, it’s natural to ask questions about their effects, duration, and metabolism.
While CBD oil doesn’t get you high like marijuana products, it does get stored in your fat tissues. Common drug tests only look for THC metabolites, but some people are still concerned about how long CBD oil will last in their system.
Hemp was just legalized in 2018 under the amended Agricultural Act, and despite the rolling legalization movement (no pun intended here!), scientists are still trying to determine the time the metabolites of cannabis are stored in the user’s system.
This article will explain the time CBD acts in the body, how long it takes to flush CBD out of your system, and why it’s unlikely that it will cause you to fail a drug test.
How Long Does CBD Oil Stay in Your System? (Important Factors)
As much as we’d like to provide you with a universal timeframe for the time CBD oil will stay in your system, it’s easier said than done. Studies are limited in this regard, and different factors can influence the duration.
There are five major variables that determine how long CBD remains in your body:
The Dose of CBD
Usually, it takes about one day for CBD to be flushed out of your system after taking a single dose. However, the higher the dose, the more time your body will need to get rid of it.
How Often You Consume CBD
The frequency of use also determines how long CBD will stay in your system. CBD accumulates in the body over time if you’re a regular user. Most experts suggest taking CBD for at least two weeks to see how it affects your health and whether or not you’re reaping the benefits. For occasional users, the time CBD leaves the system is shorter.
Your Unique Body Chemistry
Everybody is different. People have different diets, lifestyle habits, metabolisms — all of which can affect the way they metabolize CBD. Your fat content, body mass index, and age will also influence the time CBD remains in the body.
CBD is found in many different formats. The method of administration affects everything from the onset and duration of effects for the time required for the CBD to leave your system.
CBD is available as the following products:
- CBD oil
- CBD capsules
- CBD edibles (e.g. gummies and honey sticks)
- CBD vapes
- CBD topicals
The fastest and most efficient way to deliver CBD into your system is through vaporization. Vaping provides quick effects and leaves the body in a similar time manner. CBD oils and tinctures have a slower onset (15–20 minutes), but they last longer (up to 6 hours). Oral products like capsules and edibles need to pass through the digestive system, so their onset may be delayed by as much as 90 minutes. On the other hand, oral forms of CBD provide the longest duration, up to 10 hours. If you’re looking for localized relief from your discomfort, topicals are a good choice. Their absorption rate and duration time may vary depending on the product’s formula, so make sure to carefully read the ingredients list before buying.
Taking CBD on Empty / Full Stomach
How often you eat, how much, and what you eat plays an important role in the metabolism of CBD. If you take CBD on an empty stomach, it will be metabolized and eliminated faster than when you take it along with a meal.
Studies on CBD’s Metabolism: How Long Does It Stay In Your System?
As mentioned, there aren’t many studies investigating the time CBD oil stays in the user’s system. Below we present the most important research to date.
A 1991 study published in the journal Pharmacology, Biochemistry & Behavior examined the levels of CBD in the participants after high doses administered daily. The authors tested a daily dose of 700 mg of CBD on 14 patients with Huntington’s disease. One week after the experiment stopped, the CBD levels were measured at just 1.5 ng/mL. The research team concluded that CBD concentrations were “virtually undetectable.” (1)
According to a double-blind, randomized placebo-controlled 2005 study from the journal Therapeutic Drug Monitoring, low doses of CBD — 1.35 mg taken with 2.5 mg of THC —disappear from the body after nine hours from ingestion (2).
Finally, a 2018 review of existing CBD studies found that the estimated half-life of CBD from CBD oil was 2–5 days for daily users. Other methods of administration brought varying half-lives (3).
What is the Half-Life of a Substance?
The half-life of a compound is a popular unit in medicine that helps researchers determine the time it takes for half of the initial dose of a substance to leave one’s system (4).
Based on the assumption that the half-life of 10 mg CBD is 3 hours, the timeframe for how long CBD stays in your system works like this:
- 1 hour after administration – CBD reaches peak blood levels of 10 mg
- 3 hours (first half-life) – the amount of CBD is reduced to 5 mg
- 6 hours (second half-life) – there’s 2.5 mg of CBD in the body
- 9 hours (third half-life) – only 1.25 mg of CBD circulates in the body
- 12 hours (fourth half-life) – your body is left with 0.62 mg of CBD
As we said, the half-life of CBD depends on the consumption method and how often you take CBD oil.
How Long Do the Effects of CBD Oil Last?
The form of CBD determines how long your body will need for the effects to take hold — and how long they will last. It also affects the bioavailability of cannabidiol (5).
Here’s what to expect:
Sublingual CBD (CBD Oils, Tinctures & Sprays)
Sublingual use is a fairly efficient consumption method because CBD can pass directly into the bloodstream using the tiny capillaries under your tongue. This complex network of blood vessels allows the CBD to avoid the first-pass metabolism in the liver. Sublingual consumption produces its effects within 15–20 minutes after ingestion, lasting between 4–6 hours. The bioavailability of CBD oil — the amount that eventually enters the bloodstream — is measured at 35%.
Oral CBD (Capsules & Edibles)
Oral ingestion is one of the most common consumption methods for CBD products. Taking a capsule or eating a CBD gummy bear is a relatively effective way to reap the benefits of this cannabinoid. However, oral consumption is also the slowest way to deliver the effects of CBD. Since you swallow the product, the CBD needs to be metabolized in the gut before entering the bloodstream. From there, it can reach your endocannabinoid system within 30–90 minutes depending on your metabolism and whether or not you had eaten something before taking CBD.
This phenomenon is referred to as the “first-pass metabolism,” where the liver enzymes decrease the amount of CBD before its remaining dose can start circulating in the body. Although common among on-the-go users and those who dislike the taste of CBD oil, capsules come with the lowest bioavailability. Only up to 20% of swallowed CBD ends up in your bloodstream.
The delayed onset also leads to the gradual release of CBD into the endocannabinoid system, so the effects last longer than with oils — up to 10 hours.
As mentioned earlier, vaporization provides the highest bioavailability of all CBD formats, with up to 56% of inhaled CBD entering your system. When you take a puff from your CBD vape pen or inhale the vapor from a high-CBD flower, the active ingredients enter the bloodstream using the lung tissue. Doing so ensures fast-acting effects; they usually take hold within 5 minutes after inhalation. On the other hand, they provide the shortest duration of all consumption methods; vaporized CBD will last up to 3 hours.
Topical formulations range from creams to salves to gels, lotions, bath bombs, and other skin care products. This form of CBD is suited for people who want to target localized problems, such as irritation and discomfort. Sportspeople and athletes use CBD topicals to improve post-workout recovery. When you apply CBD to the skin, it reaches the epidermis layer, where the CB2 receptors are located. The activation of these receptors leads to an array of benefits related to skin health. Again, the absorption rates of CBD topicals vary between different formulas. Make sure to check the list of ingredients and look for the type of fats and oils used as the product’s base.
Will CBD Oil Show Up on a Drug Test?
In most cases, CBD won’t show up on a drug test.
The majority of drug tests are designed to look specifically for THC metabolites or other illicit substances. Employers must follow the Substance Abuse and Mental Health Services (SAMHSA) guidelines — and they don’t include detecting CBD.
But since hemp-derived CBD products may contain up to 0.3% of THC, this raises questions about the possibility of THC showing up on a drug test when the subject is a daily user.
The chances of testing false-positive for THC when taking full-spectrum CBD oil are extremely low. You would need to take around 2,000 milligrams daily to risk failing a drug test.
This can be easily avoided by choosing a broad-spectrum product that contains all the non-psychoactive ingredients of hemp, but without traces of THC. If you’re allergic to some of the hemp compounds, CBD isolate will be the safest bet.
How do you ensure that your CBD oil contains 0.3% of THC or less?
Always look for the Certificate of Analysis (CoA) from a third-party laboratory. An independent lab will look at the potency of CBD, the THC content in your CBD oil, and will detect any potential contaminants in the tested sample. Reputable companies share their lab reports with customers either on their websites or on request.
Even if you test false-positive for THC, you can tell your employer that you take full-spectrum CBD oil and ask for another screening.
How Long Is CBD Detectable in Urine?
Studies are limited when it comes to how long CBD stays in a person’s urine. A 2016 study conducted by researchers from Pacific Toxicology Laboratories in California found that CBD needed only 24 hours to flush CBD out of the subjects’ bodies. After two hours from the administration, 14 out of 15 participants still tested positive for CBD metabolites (6).
How Long Is CBD Detectable in the Blood?
Although not as common as urine tests, blood tests can be used to detect THC metabolites from CBD oil. The reason why they’re not the preferred method of drug testing is because of how quickly THC is eliminated from the bloodstream. The time THC and CBD are detectable in your plasma is about five hours after you take it. However, their metabolites can be present for up to a week.
How Long Is CBD Detectable in the Hair?
A hair test can detect drugs for an extended period of time. These tests can detect the THC metabolites from CBD oil for as long as three months post-administration. The time CBD stays in your hair isn’t clear, but hair tests are very uncommon for both cannabinoids.
Does CBD Interact with Medications?
CBD-induced drug interactions are a real thing. CBD may either shorten or prolong the time it takes to flush the active ingredients in medications from the body.
CBD acts as a substrate and inhibitor of CYP450 enzymes, which metabolize the substances in drugs. Therefore, CBD may affect the metabolism of many pharmaceuticals. Depending on the type of interaction, CBD may cause a subtherapeutic effect, or lead to excessive concentrations of the drug in the bloodstream.
If you take any medications, we encourage you to consult a doctor you trust to avoid the said interactions and maximize the health benefits of CBD oil.
Is CBD Toxic for the Liver?
One study on mice has found that extremely high doses of CBD administered acutely can increase the number of liver enzymes and cause toxicity. However, the results haven’t been replicated in humans, not to mention that the CBD dose was exorbitant considering the weight of the mice. Some studies report that CBD is well tolerated in daily doses of up to 1,500 mg. The World Health Organization (WHO) has also acknowledged CBD as a safe substance.
That being said, CBD has a few mild side effects when taken in large doses. These include dry mouth, changes in appetite, dizziness, fatigue, and diarrhea.
The good news is that none of these reactions are life-threatening, not to mention that it’s impossible to fatally overdose on cannabinoids.
CBD and Breastfeeding: Can CBD Pass Into Your Baby’s System?
Doctors suggest that breastfeeding mothers abstain from CBD for at least 1 week before they start breastfeeding. The Food and Drug Administration (FDA) holds a strong stance against the use of CBD during breastfeeding due to the lack of sufficient research on how CBD affects breastfed babies. We only know that some amount of cannabinoid can pass into a baby’s bloodstream with milk.
Until researchers establish the safety of CBD during breastfeeding, it’s safe to avoid it.
So, How Long Does CBD Oil Stay in Your System?
Low-to-moderate doses administered acutely shouldn’t stay in your system for more than 24 hours. Even high doses of CBD should disappear from the body within a week.
However, regular use of CBD may cause it to remain longer in your system. For some people, it takes more than a week to flush CBD completely out of the body. That’s because CBD builds up over time in the fat tissues.
The time CBD oil will stay in your system is determined by several factors, including your age, metabolism, weight, dosage, frequency of use, consumption method, and the use of other medications.
The good news is that drug tests don’t look for CBD, so if you take normal doses of full-spectrum CBD oil, you’re in the clear.
