Standard drug tests look for THC rather than CBD. But CBD users are still at risk of failing drug screenings. Find out how long CBD stays in your body. Several factors determine how long CBD stays in your system. Learn how to predict the effects of CBD, how long it will show up on drug tests and more. CBD typically remains in your body for two to five days, though this depends on certain factors. Learn all about how long CBD stays in your system here.

How Long Does CBD Stay in Your System?

Cannabidiol (CBD), and tetrahydrocannabinol (THC) are two of the most well-known compounds in cannabis plants. The latter has psychoactive effects and causes the high marijuana is famous for. THC use impairs judgment and coordination.

As a result, THC and its byproducts are what’s tested for in standard 5-panel and 10-panel drug tests. Pure CBD will not show up on these tests. Tests that can detect CBD are available but they’re more expensive and are not widely used.

How Long Does CBD Stay in Your Urine?

In some cases of heavy use, CBD can stay in the system for up to a week, and windows of detection extend to more than a month. In the case of single exposures, THC and its metabolites are detectable in urine for about 3 days after the last time taken.

Most urine tests come back positive if you consume more than 2,000 mg of legal CBD products per day. This might seem like a large number but frequent use of CBD products could trigger a false-positive test result. This is a possible outcome when you consider that CBD and THC accumulate in the body.

How Long Does CBD Stay in Your Blood?

Blood tests focus on recent use. THC is only detectable in blood for approximately 5 hours, but its metabolites can remain in the system for up to 7 days.

Taking CBD products with unknown amounts of THC would only yield a valid result if a lab test was done on a blood sample within this short period of time.

How Long Does CBD Stay in Your Saliva?

THC can be found in saliva for about 72 hours but chronic use of CBD products tainted with THC could extend this window of detection. Analyzing saliva to detect CBD is rare.

How Long Does CBD Stay in Your Hair?

In general, substances such as CBD can be detected in hair up to about 3 months after they were last taken. Trace amounts of THC will likely not show up in a hair test.

How Long Do the Effects of CBD Last?

The duration of CBD’s effects depend largely on the method of consumption, but in general, CBD lasts between 2 and 6 hours.

Smoking or vaping causes the substance to enter the body rapidly via the lungs. Two teaspoons of a concentrated CBD tincture taken sublingually can also take effect within an hour. These fast-acting modes of administration tend to wear off sooner too.

Chewables have to go through the GI tract before entering the bloodstream, so effects take a little longer to kick in with peak blood levels being reached at around three hours after ingestion. This method of consumption has a more prolonged effect lasting up to eight hours. People often over-consume edibles because the results aren’t instant.

Topical applications like creams also last longer. Because CBD is not psychoactive, it’s more difficult to determine when it’s actually taking effect.

How Does CBD Affect the Brain?

Research on THC in the 1990s led to the discovery of the endocannabinoid system (ECS). Scientists found that our bodies naturally make molecules that are similar to cannabinoids from cannabis plants.

These molecules support our immune systems and are broken down when they’ve completed their function. There are receptors for endocannabinoids all over the body including the central nervous system (CNS). And as it turns out, THC binds to them and CBD does so weakly or not at all. CBD may in fact reduce the effects of THC by blocking it.

CBD influences the release of neurotransmitters in the brain which impact pain, anxiety, sleep, and other functions.

Factors That Influence Detoxing from CBD

Regardless of gender, CBD is generally believed to have an elimination half-life of one to two days. This means that half of the dose leaves the body at this time. But how long it lasts is not the same for everyone. Unique factors that determine how quickly CBD is expelled include:

  • Age
  • Weight – CBD is fat-soluble and is stored in fatty tissue
  • Frequency of use – CBD can accumulate in your system
  • Mode of ingestion
  • Dosage
  • Potency
  • Metabolism
  • Genetics
To summarize:

Most drug tests look for THC rather than CBD. If you are concerned about an upcoming drug test, avoid the use of CBD products that could contain unknown amounts of THC. THC can typically be detected within these windows:

  • Urine – 3 to 30 days
  • Blood – 5 hours up to a week
  • Saliva – 72 hours or more with heavy use
  • Hair – about 3 months

Treatment for CBD Dependence

According to the World Health Organization (WHO), pure CBD has no abuse potential. But CBD products can cause psychological dependence. And THC can cause marijuana use disorders and withdrawal symptoms which negatively impact users’ health and productivity.

If you or someone you know is struggling with a dependency on CBD, help is available. Treatment programs include tailored therapy sessions to address the underlying issues leading to substance misuse. Humans can form bad habits, but bad habits can be unlearned. Take the first step towards a brighter future today.

How Long Does CBD Stay in Your System?

CBD can remain detectable in your system anywhere from 10 hours to 25 days depending on whether you smoke it or injest it and how often you use it.

Cannabidiol (CBD) is a popular chemical compound capable of exerting positive effects on users over time. Yet not everybody experiences the same benefits with CBD use. One reason for this discrepancy could be that people metabolize the chemicals differently. This raises an important question: How long does CBD stay in your system?

Factors That Influence How Long CBD Stays in Your System

Several factors determine how long CBD stays in your system. The first one is the quantity of CBD. The more CBD you take, the longer you’ll experience the benefits, with heavy doses lingering for the better part of a day.

Quality of CBD matters, too. You might take 100 mg of CBD and feel next to nothing if it’s low quality. Pure CBD stays in your system longer than products with fillers and additives. However, there should be no difference between the duration of full-spectrum CBD and that of broad-spectrum CBD.

Your frequency of use also influences how long CBD remains in your system. If you are taking CBD every day, it can cause cannabidiol to accumulate in your body. That’s why you may need to take CBD for a week to begin to feel the desired effects since small doses clear your bloodstream rapidly.

Your body type and metabolism dictate how fast CBD effects will occur and how long they will remain in your body. For instance, people with a fast metabolism can process cannabis products within minutes, while others may take hours. CBD will also leave your system quickly if you have a low body mass index and high-water content.

The food you eat before taking CBD impacts how the compound reacts in your body. If you eat CBD on an empty stomach, it’s the first thing your metabolism will break down. However, if you have a big meal beforehand, it will slow your metabolism and digestion when processing CBD.

Finally, your method of consumption when you take CBD makes a difference in how soon you will feel the effects of CBD and how long it will last. Research shows that vaping provides almost immediate benefits because the cannabidiol goes directly into your lungs and then your bloodstream. If you use a cream, lotion, or edible, your metabolism has to break down the product before you feel the effects, which may take hours.

How Long Do the Effects of CBD Oil Last?

As we mentioned above, several factors dictate how you may experience CBD. For example, a short, thin man using CBD isolate for the first time will experience pain relief for longer than a large man that uses it habitually. As a rule of thumb, CBD oil lasts for four to six hours long, though a heavy dose may last 24 hours.

You will find three popular methods of CBD consumption: sublingual, inhalation, and topical. Sublingual involves placing the CBD product under your tongue. The cannabidiol will take effect in two to four minutes since the CBD travels through the mucous membranes in the mouth and into the bloodstream, bypassing the digestive system entirely.

Inhalation allows people to ingest CBD through vaporized particles. A joint or vape pen turns the cannabidiol into fine specks that individuals can inhale. Once the CBD enters the lungs, the body absorbs it rapidly, making vaping ideal for immediate pain relief.

Topicals take the longest amount of time to work, ranging from 15 minutes to two hours. The lotion, cream, or salve has to dissolve into the skin before the metabolism can process it. The slow infusion means that topicals have the most extensive detectable window of any method of consumption.

Does CBD Show Up on a Drug Test?

According to the 2018 U.S. Farm Bill, any hemp-derived product must contain less than 0.3% tetrahydrocannabinol (THC). That means that both CBD and minute amounts of THC are present in products like full-spectrum hemp-derived CBD.

That trace amount of THC can be a valid concern if you want to pass a drug test. On the other hand, if you use a broad-spectrum CBD, by definition, it should have no THC. However, you only have the word of the company that provides it that all THC has been removed unless you personally have it tested.

This distinction matters because most companies test for THC, not CBD. THC, the compound responsible for psychoactive effects, is the main component of the marijuana form of cannabis but only a very minuscule part of hemp-derived CBD. While CBD and hemp products are legal in some form in most states, the same does not apply to cannabis containing more than 0.3% THC, known as marijuana.

Expect to have small amounts of THC stay in your system and show up on drug tests unless you consume broad-spectrum hemp CBD or CBD isolate. The chances of a positive drug test go up with routine ingestion of CBD-containing THC. That’s because your fat cells may store the THC for a few days after ingestion.

Just because you don’t feel the effects of the THC in hemp-derived CBD doesn’t mean it’s not detectable in urine, blood, or saliva drug tests. The half-life of CBD ranges between 18 and 32 hours. The half-life refers to the point at which the CBD products have 50% of the original dose’s potency.

The Half-Life of CBD

Every drug that enters your system gradually leaves it. CBD is no exception. Your body will break down the cannabidiol in your digestive system and liver before getting rid of it through urine, hair, and sweat.

A study from Pharmacology, Biochemistry, and Behavior looked at CBD half-lives on patients with Huntington’s disease. Each person received a 700 mg dose of CBD each day for six weeks. Researchers found that potency dropped 1.5 ng/mL a week after the last dose.

So what do these results tell us about the half-life of CBD? The study found that even a substantial dose of CBD is undetectable after a week. The patients with Huntington’s disease took 700 mg of CBD per day when most people only use 100 mg of CBD or less.

How long CBD stays in the body depends on how frequently someone uses it. A person that uses CBD more regularly may have it stay in their system for three or four days, while a first-timer may only have it detectable for two days. Researchers have determined that whether a user is male or female does not influence CBD’s half-life.

Let’s use an example to illustrate how long it takes to flush CBD from your system. If you consume 100 mg of CBD that has a half-life of one day, you can expect to have the maximum concentration of CBD (100 mg) in your body after one hour.

The CBD concentration in your body will drop 50% (to 50 mg) after 24 hours. This point marks the first half-life. The CBD concentration will exponentially decline from here until it disappears.

The next half-life occurs two days after your initial dose. The concentration has shrunk to 25 mg and will drop to 12.5 mg and 6.25 mg in the subsequent daily measurements. At this point, the CBD should be undetectable.

Types of Drug Tests for CBD and THC

There are four main types of drug tests that are used to detect CBD and THC. Each type tests a different part of the body, which results in varied results.

Urine Drug Test

CBD remains in urine for 3 to 5 days. As long as you don’t use CBD for at least 5 days leading up to your test, you should be fine. Your metabolism can process and excrete hemp-derived CBD relatively quickly so that it’s no longer detectable.

THC metabolites, however, linger in urine for up to 15 days. Metabolites are a byproduct of the body metabolizing a compound and turning it into a different substance. These compounds stay in your system longer than the parent drug, which is why testers look for them to find evidence of drug use.

Urine tests are one of the most common and popular ways to screen for cannabis. There’s a good chance you’ll encounter one at your next screening.

If you have used full-spectrum CBD recently, you can help it leave your system faster through vigorous exercise and fluid consumption.

Hair Drug Test

The THC metabolites from CBD products stay in your system for up to 90 days. The compounds that pass through your bloodstream eventually become part of your hair. It takes at least 5 days before CBD and THC are detectable in your follicles.

The good news is that hair drug tests are rare. Most employers and organizations rely on saliva or urine tests because they’re faster and cheaper. There’s also the risk of prescribed medications for your hair, leading to false positives.

Saliva Drug Test

Research on how long CBD stays in the saliva isn’t as robust as in other areas. If you consume CBD oil, expect the dose to last in your oral fluids for up to three days. The duration may be longer depending on your method and frequency of use.

Once you consume the CBD oil, it will appear on the saliva test within minutes. Fortunately, few companies use this method to look for THC or hemp-derived CBD in the body. States that permit cannabis allow people to have up to four nanograms of CBD per milliliter in their saliva.

Blood Drug Test

Blood tests are far less prevalent than urine or saliva-based ones. One reason is that they’re not as reliable for detecting CBD or THC. THC is only detectable in the bloodstream for up to five hours, while CBD stays in your blood for up to a week.

Blood tests work better to determine if someone is currently impaired, which is why police officers might take a blood sample following a DUI charge. If you live in a state where cannabis is legal, you can have up to five nanograms of THC per milliliter of blood.

How to Detox

We’ve answered the question, “How long does CBD stay in your system?” Now, it’s time to find solutions to speed up the excretion of CBD, THC, and other cannabinoids. The process can increase how fast your body metabolizes CBD and also lower the chances of a positive test, even if you ingested CBD within 24 hours of your screening.

The first step is to stop taking any product that contains THC. That means going cold turkey. Lowering your frequency of use to zero ensures that no new CBD or THC metabolites will appear in your system before the test.

Step two is to hit the gym. Vigorous exercise speeds up your metabolism, forcing your body to sweat and break down fat cells for energy. Research suggests that 45 minutes of intense aerobic exercise can increase your metabolic rate and may accelerate CBD’s exit from the body.

Don’t forget to drink plenty of water and eat healthy, too. The body needs water to cleanse your system and expel toxins. A diet full of fats, sugars, and processed foods makes it more challenging for your metabolism to process the CBD out of your system.

Using CBD While Breastfeeding

The U.S. Food and Drug Administration recommends that women who are pregnant or breastfeeding not use CBD. Research on CBD’s effects on children remains in its infancy, so the FDA advises a cautious approach.

Researchers do know that CBD can pass from mother to child through breast milk. CBD is a fat-soluble compound, meaning that it gravitates towards fatty compounds as a carrier. A CBD product may also have THC, which could negatively affect the breastfed child.

Important Questions

How long does hemp or hemp oil stay in your system?

When people ask, “how long does pure CBD oil stay in your system?” They are usually talking about ingesting CBD as an oil or tincture. When taken in this form, the CBD will take longer to leave the system.

If you are a heavy user, it could take up to 25 days, but 10-14 days is more common.

How long does CBD stay in your blood?

CBD can stay in your blood anywhere from 2-25 days after consumption. Your method of consumption, frequency of use, and BMI will all affect how quickly it leaves your body.

How long does CBD stay in your system for a saliva test?

CBD is detectable in saliva for around 72 hours after use.

How long does it take for CBD to get out of your system?

It takes anywhere from 2-25 days for CBD to completely get out of your system. It will leave more quickly for people that only use it once and have a low body fat percentage.

How to get rid of CBD oil in your system?

To clear your system of CBD, you need to do several things. Your body will eliminate CBD naturally in 2-25 days, but with some help, it can happen sooner. CBD is a fatty molecule, so it loves the fat in your body. Pushing it out of the fat with exercise and lots of water helps the body to eliminate it. Also, getting a lot of fiber in your diet can aid the process further.

How long does a CBD gummy stay in your system?

Like CBD oil, CBD gummies stay in your system longer than CBD that is smoked or vaped. If you are a heavy user, it could stay in your system up to 25 days, but 10-14 days is more common.

How long does CBD stay in your hair follicles and hair?

While a hair test for CBD is extremely uncommon, it is possible for CBD to be detected in the hair up to 90 days after use.

How long does CBD stay in your system when smoked?

While smoked CBD can be metabolized faster, it’s best to assume that it takes 2-25 days for it to completely leave the body. It will leave more quickly for people that only use it once and have a low body fat percentage.

How long does CBD oil stay in your system for a urine drug test?

When people ask, “How long is CBD detectable in urine?” they are usually concerned about a drug test. It’s very rare for CBD to be part of a drug test. THC, the other major chemical in cannabis and hemp is what’s commonly tested for. Even legal CBD products can have .3% THC in them. This could be enough to trigger a positive on drug test. If you are at all concerned, it’s best to not consume any CBD products 25 days before a test.

The Bottom Line

One of the most frequently asked questions about CBD oil and CBD products is “How long does CBD stay in your system?” The answer depends on several factors, including how much you use, your body weight, metabolism, and consumption method.

While most drug tests look for THC and not CBD, your CBD products may contain trace amounts of THC that lead to a failed drug test. While CBD has a half-life of 18 to 32 hours, it can stay in your system for several days.

Here’s the bottom line: You’re unlikely to fail a drug test because of CBD alone in isolate form. Combining THC and CBD in full-spectrum form is a different story. If you want to eliminate the chances of a positive drug test, you can use CBD isolate or no CBD product at all.

How long does CBD stay in your system?

CBD (short for cannabidiol) has taken the wellness world by storm. Potentially offering benefits like reduced stress , improved sleep quality and better moods , the compound’s popularity keeps growing.

However, while many have started their CBD journey without a second thought, others are put off by fears around how long it will stay in their system, something that could pose issues when it comes to things like drug tests. After all, CBD comes from the hemp plant, which can naturally contain THC, the psychoactive compound that itself is detectable in your system for up to 30 days.

That said, CBD products sold in the UK shouldn’t have THC in them, and CBD itself doesn’t show up on a drug test. CBD can stay in your system for two to five days, however, this is dependent on several factors that we’ll explore in this guide.

Which factors affect how long CBD stays in your system?

While two to five days is the typical range for how long CBD stays in your system, the durations can be impacted by the following aspects:

The dosage

Like with most substances, the higher the dosage of CBD you take, the longer it will stay in your system. Here at TRIP, we recommend taking 15 to 30mg a day at first, before increasing in increments of 5mg each week after the first seven days. For reference, one full dropper of our original CBD oil contains 20mg CBD, while there’s 66mg CBD in the strong version.

The frequency of consumption

How often you take CBD will also impact the time it stays in your system. The compound builds up in your body over time if taken regularly, meaning, the more you take CBD, the longer it will stay there. If you only use it from time-to-time, however, it’ll clear your system pretty quickly.

Your body

No two people are the same, and our different body types mean that CBD will impact people in different ways. Aspects like your body mass index, water content and metabolism are just a few of the things that will affect how long CBD stays in your system. For example, the faster your metabolism, the quicker it will pass through.

Your diet

The food you eat, how much you eat, and when you eat can all impact how long CBD stays in your system. Say you consume CBD on an empty stomach, it will get metabolised and eliminated quicker than if you had it in a full stomach, which would slow its digestion.

The method of use

There are numerous ways to take CBD, from oils and drinks , to vaping and edibles, and which method you choose will again affect how long CBD remains in your body. For example, when vaping CBD, it enters your lungs and takes effect quickly, meaning it won’t stay in your system too long. Whereas, if you ate a CBD edible, you’re relying on your digestive system to metabolise it, which can take some time.

How long does it take for CBD to work?

For CBD to work, it must be able to reach the relevant receptors in the body, which is typically achieved through absorption into the bloodstream. Most people take it via CBD oil, which can take between 15 and 60 minutes to absorb. Again, aspects like weight and genetics impact this and it can take up to an hour for CBD to start working overall.

That said, some methods are much quicker — for example, CBD can be absorbed into the bloodstream in just three minutes by vaping it.

For more information on how long CBD takes to work, check out our guide to the topic .

How long do the effects of CBD last?

Again, how long CBD’s effects last depends on aspects like the dosage, your body and the method of use. As a general rule of thumb though, you should feel the effects of CBD for between two to six hours.

Does CBD show up in drug tests?

Even if you have lots of CBD in your system, it shouldn’t show up on a drug test . However, the issue with taking some CBD products is that they may contain THC, which will show up. Some products have traces of the psychoactive compound, so it’s important to be able to differentiate between the different types of CBD products so that you can avoid the risk of accidentally consuming THC. The three main types are:

  • Full spectrum CBD – These products include all of the naturally occurring compounds from the plant they’re extracted from, including THC.
  • Broad spectrum CBD – Broad spectrum CBD products are similar to full spectrum types, but go through a process to remove the THC. However, trace amounts may still be identifiable in a drug test.
  • CBD isolate – These products contain CBD only.

It’s a good idea to avoid full or broad spectrum CBD products and stick with CBD isolate products if you don’t want to risk testing positive for THC. Here at TRIP, we ensure the purity of our CBD products with third party lab testing, so there’s no possibility that you’ll fail a drug test after consuming them.

How long is CBD detectable in urine?

Research on how long CBD stays in a person’s urine is limited. However, one study from 2016 found that subjects tested positive for CBD metabolites within two hours of administration, but flushed it out of their bodies within 24 hours.

How long does CBD stay in your blood?

While not as common as urine tests, blood tests can be used to detect THC metabolites from CBD oil. However, THC and CBD are very quickly eliminated from the bloodstream, which is why urine tests are the preferred method of testing. Overall, THC and CBD are only detectable in your blood for up to five hours after you take them, though their metabolites can be present for up to a week.

How long does CBD stay in your saliva?

Analysing saliva to detect CBD is rare, meaning there isn’t any information out there on how long it stays in your body this way. However, if the CBD product you take contains enough THC for it to be detectable, the psychoactive compound can be found in saliva for up to 72 hours.


In order to ensure you don’t mistakenly consume THC when using CBD, it’s recommended to always buy CBD products from reputable, trusted brands. Be sure to check that the seller you choose is following the necessary regulations and has a COA (Certificate of Analysis) that confirms what they’re advertising is legitimate.

Here at TRIP, we create our CBD products in line with UK and EU legislation, with each and every one third-party lab tested to ensure they don’t contain THC. Check out all of our products here , and don’t hesitate to drop us a text @ +4478 6212 6624 if you have any questions for the TRIP team.
