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 in 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 use of CBD products which 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.

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.
I’m Not Paranoid or Anything, but How Long Does CBD Stay in Your System?

You can expect the effects of CBD to last for a few hours. But even after it wears off, is the stuff still in your system? More importantly — how long does it actually stick around for?
Generally, you should count on CBD hanging around in your body for anywhere from 2 to 5 days.
Of course, that’s a ballpark range, and there are lots of factors that can influence how long the stuff stays in your individual system. That includes your size, your dose, how often you take it, and even whether you took it with food.
In short, there’s no way to know exactly how long CBD can be detected in your body for.
But by reading up on influencing factors, you might be able to get a better sense of what to expect. Here’s what experts know, plus whether CBD that’s still in your system will show up on a drug test.
What exactly happens when you take CBD anyway? To understand how long the stuff stays in your system, it helps to take a step back and look at the bigger picture.
When you use CBD, you’ll feel the effects within 15 to 45 minutes. Precisely how long it takes depends on a bunch of factors including the dose you took and your body composition.
Your delivery method plays a role too. Vaped CBD enters your lungs and takes effect quickly. (Though you probably shouldn’t vape it.) Tablets and oils tend to kick in pretty fast too. But edibles, creams, and lotions usually take a little longer.
At some point you’ll start to notice a feeling of calm relaxation wash over you, kind of like you just finished a really chill yoga class or got a great massage. You’re not high the way you would be if you smoked marijuana or took something with THC. You’re just chill. Like a more mellow version of yourself.
As for how long you’ll keep reaping those stay-calm benefits? Again, a lot of it boils down to your delivery system. Vapes will wear off in about an hour, while you’ll feel the effects of oils or edibles for a few hours or more. If you’re using a skin patch, the effects could last up to 2 days.
CBD will stay in your body for anywhere from 2 to 5 days. But there’s no one-size-fits-all answer for when you can expect CBD to kick in, how long you’ll feel the effects, and ultimately, how long it will stick around in your particular body.
That said, there are some clues that can help you figure out whether your body is likely to get rid of the stuff on the faster or slower side. These include things like:
Your body composition
CBD is a fat-soluble compound, meaning it gets stored in the body’s fat cells. Leaner people with more muscle and less body fat will metabolize CBD quicker, so it’ll exit their systems faster. If you have more body fat and less muscle tissue, CBD will stay in your cells a little longer.
Your activity level
How physically active you are can also affect how quickly (or slowly) CBD gets metabolized. If you’re the kind of person who works out every day, you can probably expect CBD to make its way out of your body on the faster side. Tend to be more sedentary? The exit process might be a little slower.
How often you take it
Taking CBD on the reg will cause it to build up in your system, so it’s less likely to clear out. The opposite is true if it’s your first time taking it or you only take it once in a while. In that case, it’ll probably leave your system sooner.
Whether you take it with food
Using CBD with food is kind of like drinking alcohol with food. Do it on an empty stomach, and it’ll probably hit you sooner and clear out quicker. Do it with something to eat (or just take a CBD edible), and the food will cause the CBD to be metabolized at a slower rate.
All in all? There’s no clear-cut answer to how long it’ll take CBD to leave your body. But you can expect it to take longer if you’re heavier or less active, if you take CBD regularly, or if you use it with food.
On the other hand, it will likely clear out faster if you’re leaner or more active, only use CBD once in a while, or you take it on an empty stomach.
Generally, you should count on CBD hanging around in your body for anywhere from 2 to 5 days. Here’s what experts know, plus whether CBD that’s still in your system will show up on a drug test.
