How long CBD lasts in the human body, and how long the effects persist, depends on a variety of factors, including how it’s consumed. 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. Although CBD oil, also known as cannabidiol, is legal, it contains traces of THC. Find out how long CBD oil can be detected in your system here.
How Long Does CBD Stay in Your System?
How long CBD effects last depends on several factors, including the user’s metabolism and if they use CBD regularly. A single dose of CBD may keep working for several hours, and the cannabinoid may persist in the body for days or weeks. The non-intoxicating compound CBD is known to have a variety of beneficial effects, including reduction of pain and inflammation, and anxiety relief. But it does not get you high.
How long does CBD last in your system?
CBD (or cannabidiol) is stored in fat cells in your body, and theoretically can remain detectable for days or even weeks in a blood test. However, research on how long CBD oil stays in the system is spotty, because there’s no real demand for testing. Few employers care if employees consume a non-intoxicating drug that is used mainly to treat pain and anxiety—and commercial testing protocols don’t measure CBD anyway.
How long does CBD keep working?
The first thing to know is that you need to absorb enough CBD for it to have any effect at all. Depending on how you administer CBD, much of its benefit can be lost. Swallowing it forces the drug to first pass through the liver, and as much as 95 percent never gets into the bloodstream. The highest bioavailability (how much is absorbed and gets into the bloodstream) comes from CBD that’s vaped or smoked, with CBD oil tinctures applied sublingually (under the tongue) finishing second.
Because inhaled CBD reaches the brain rapidly, users may feel a much more immediate and pronounced effect than they would from tinctures or edibles. But the therapeutic effects—reduced inflammation, pain and anxiety—are eventually noticeable from all forms of consumption, assuming you use enough. Proper CBD dosing can require some experimentation.
Generally, the effects of CBD wear off within just a few hours, but that depends on the amount of CBD taken, the method used, and the user’s size, metabolism, and history of use. If you begin to feel the pain or anxiety begin to return, you can simply take more CBD. There is no practical way to overdose on CBD.
How long is CBD detectable in your body?
CBD disappears from the body relatively quickly. In a study following 14 patients who were each given about 700 mg of CBD a day orally for six weeks, the average plasma level fell to just 1.5 ng/mL a week after the final dose, and was undetectable after that. The authors estimated the CBD half-life to be about 2-5 days.
It generally takes 5.5 half-lives for a drug to be fully eliminated from the system. So CBD taken orally would completely leave the body in about 11-28 days, but it may be impossible to detect on a blood test well before that. The half-life for vaped or smoked CBD in blood plasma is much shorter than for ingested CBD—just a few hours. A regular user may take longer to fully clear CBD from their system than an occasional or new user.
Research showing how long CBD is detectable in urine is rare, but one study showed a single test subject maintained detectable CBD in his urine for only 24 hours. In any case, CBD is almost never included in standard drug tests (like those given by employers).
If you’re concerned about CBD causing a failed drug test at work, it’s best to restrict your use to the CBD products that contain no THC or almost no THC: CBD isolate and broad-spectrum CBD.
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:
- Weight – CBD is fat-soluble and is stored in fatty tissue
- Frequency of use – CBD can accumulate in your system
- Mode of ingestion
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.

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
- 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:
- Dietary supplements
- 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.
