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. How Long Does CBD Stay in Your System?
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.

CBD, also known as cannabidiol, is one of the many cannabinoids found in hemp plants. Over the last few years, CBD-infused products have continued to grow in popularity, especially as growing research uncovers the many therapeutic benefits that CBD offers.
The cannabinoid has shown to have anti-inflammatory as well as calming properties, which means less aches and pains, lower stress levels, and more balanced day-to-day living. CBD can also promote healthier sleep while also supporting various parts of the body, including the brain and heart.
Even though CBD products containing less than 0.3% THC are legal federally, there is still some risk, especially for those who are drug tested to maintain their employment. Because there’s much to learn about how CBD interacts with the body, some are on the fence about trying these products.
Here’s what you need to know about the role CBD plays in the body, as well as how long the compound stays in your system.
Factors to Consider
While CBD doesn’t have psychoactive effects like THC, which means you won’t get high or experience any type of euphoria or confusion, the compound does stay in your body for some time. However, there’s no single answer for how long CBD will stay in your system.
Instead, there are several factors that must be considered, including metabolism, dosage, method of administration, and frequency of use.
A person’s metabolism plays a huge role in how fast CBD is metabolized and then excreted. Younger people tend to have faster metabolisms, which means the compound may leave the body sooner when compared to an older user.
Dose is another important factor to consider. The amount of CBD taken influences how long it stays in your system. The higher the dosage, typically the longer it hangs out in the body.
The effects of CBD and its presence in the body is dependent on how it’s administered into the body. Smoking and vaping CBD offers immediate results, while taking gummies or some other edible delays the onset of effects for an hour or so.
A last factor to consider is frequency of use. Using CBD frequently influences how long the cannabinoid stays in the body.
So what does research say? A 2018 review of existing studies found that the half-life of CBD is two to five days when the compound is taken orally. Other administration methods have various half-lives.
On average, it’s safe to say that CBD can remain in the body for up to two weeks. But that doesn’t mean that levels are detectable in a urine or blood-based drug test.
How Long Does CBD Show Up in Urine?
Many modern drug tests analyze a urine sample to test for any illegal compounds. While there aren’t many studies that have looked at how long CBD is detectable in urine, there is one that uncovered some important details.
A 2016 study tested various forms of CBD including capsules, oils, and flowers. After two hours, the participants’ urine samples were tested, and all tested positive. However, after retesting urine samples 24 hours later, CBD levels were no longer detectable.
Be mindful that this is one of the only studies to test CBD detection in the urine. If you will be drug tested in the near future, it’s best to avoid using CBD for at least a week. Or, use only products that contain CBD isolate or broad spectrum extract.
Will CBD Make You Fail a Drug Test?
While it’s highly unlikely that CBD will cause you to fail a drug test, it’s best to lean on the side of caution. Most drug tests look for the presence of THC, which is illegal at the federal level and in most states (with the exception of a few).
With that said, it’s important to remember that CBD products can legally contain up to 0.3% THC. But because this amount is so low, it’s very unlikely that it would register on a drug test. You would have to take a huge amount of full spectrum CBD oil, something like 1,000mg or 2,000mg a day to be at risk of failing a drug test.
If you want to be extra cautious but still want to reap the benefits that CBD has to offer, you’ll be happy to know that there are tons of THC-free products available. Only products that contain full spectrum extract have THC. To avoid the compound altogether, buy products made with CBD isolate or broad spectrum CBD.
When using CBD for the first time or switching to a new product, always buy from a brand that has its products tested by a third party lab. This way you can buy with confidence knowing that the CBD contains a legal amount of THC or no THC at all.
