How Long Does CBD Stay in Your System?
Exploring how long CBD stays in your system is crucial for anyone subject to drug testing or mindful of the substances they ingest.
CBD is a non-psychoactive compound of the cannabis plant, and typically, standard drug tests are designed to detect THC, the psychoactive counterpart.
In this post, we will look into the variables that affect how long CBD stays in your system and its implications in contexts such as workplace drug testing.
How Long Does CBD Stay in the Body After Use?
The duration CBD stays in the body depends on various factors like dosage, frequency, metabolism, method of consumption, and individual body composition.
Typically, it might be detectable in blood for 3–5 days, in urine for up to several weeks (especially for frequent users), and in saliva for about 48 hours.
It can also accumulate in fat cells, extending the detection window for regular users.
Most standard drug tests target THC, not CBD, but full-spectrum CBD products may contain trace amounts of THC, leading to potential detection.
To avoid this, users concerned about drug testing should opt for broad-spectrum or isolate CBD products and verify product lab results for THC content.
Remember that CBD’s exact duration in your system will vary with individual usage patterns, and most detection windows provided are general estimations.
How Long is CBD Detectable in Your Body
Generally, most cannabidiol clears out after a week since your last ingestion.
But surprisingly, evidence of CBD use can be detected in your body even much later.
It depends on how the tests are carried out:
- Urine
- Blood
- Saliva
- Hair
1. How Long Does CBD Stay in Your Urine?
CBD is not tested for on a standard drug test, so it will not appear. But if you consumed CBD that contained THC, it could be detectable for up to thirty days after use.

2. How Long Does CBD Stay in Your Blood?
CBD shouldn’t show up in blood tests testing for drug use.
However, if there were trace elements of THC in the CBD, these can show up to 48 hours after use.
3. How Long Does CBD Stay in Your Saliva?
CBD would not show up if you had a saliva drug test.
But if there was THC in the CBD, this could show up for up to thirty days.
4. How Long Does CBD Stay in Your Hair?
CBD is not included in regular drug tests and will not show up.
However, if the CBD you consumed has some THC, it could show up 90 days after consumption.

Will CBD Show Up in a Drug Test?
CBD is legal in the UK but is restricted: it must not contain more than 0.2% THC or under 1mg if ingested.
Drug tests (blood or urine tests) screen for THC or one of its primary metabolites, THC-COOH.
Cannabidiol (CBD) should not appear on a drug test, as drug tests look for THC content rather than CBD.
Full Spectrum products contain trace amounts of THC, marijuana’s principal active ingredient.
If enough THC is present, it can appear on a drug test.
Full-spectrum CBD might lead to a positive drug test in rare cases.
It would be pretty rare for this to happen due to the nano-size particles of THC instead of full-spectrum products.

Factors that Determine How Long CBD Stays In Your System
When you ingest CBD, the effects kick in relatively quickly, but once they fade out, it doesn’t mean there’s no CBD in your body.
The following are some of the factors that determine how long CBD will stay in your system:
Metabolism
An individual’s metabolism rate determines how fast resources are expended.
CBD molecules attach themselves to fat cells; if the metabolism is rapid, they are eliminated just as quickly.
Different factors like genetics, age, and lifestyle determine the rate of metabolism.
Ingestion frequency
Individuals who don’t consume CBD often will have low CBD levels in their system instead of heavy CBD consumers.
The more cannabidiol you consume, the more CBD molecules attach to fat cells, increasing the count.

CBD dosage
Most CBD products have dosage recommendations.
Your dosage may be heavy if you’re managing a serious health problem.
But then, the greater the amount of CBD you ingest, the more latent CBD, causing it to stick around in your system for much longer.
Ingestion method
There are different ways of ingesting cannabidiol, and each method affects the rate of eliminating cannabidiol molecules.
Both sublingual ingestion and vaping make for a rapid onset of action, but vaping can quickly eliminate CBD.
Consuming CBD via oral ingestion involves the metabolism of CBD and, thus, delayed effects.
It also results in higher levels of latent cannabidiol molecules that bind to your fat cells and stay around longer.

Bodyweight
Considering CBD molecules hide within fat cells, it’s a no-brainer that an individual’s fat levels determine how long cannabidiol stays in the body.
A person with excessive body fat will have a greater surface for CBD molecules to latch on than someone with low body fat levels.
Half-Life
Half-life is a scientific phrase that roughly means how long it takes half of the substance to leave your body.
The half-life of CBD oil from oral ingestion is approximately 2-5 days for regular product users.
So, to be safe, you should allow ten to fifteen days for it to be fully processed out of your system.

How Long is CBD Detectable in Urine?
The detection period of CBD in urine can be several days but varies depending on factors like metabolic rate, frequency and amount of use, and individual body composition.
CBD is usually not the target of standard drug tests, which typically look for the psychoactive cannabinoid THC.
However, there can be concerns about trace amounts of THC in full-spectrum CBD products leading to a positive drug test, although such occurrences would be rare.
If drug testing is a concern, using broad-spectrum or CBD isolate products, which are THC-free, would be a safer choice, but verifying product labelling and lab test results is also crucial to ensure no THC content.

Final Notes On How Long CBD Stays in Your System
The maximum time CBD oil can stay in your system is thirty days. This is for oral consumption.
However, in most cases, it will be much less than that.
If you are worried about failing a drug test, it is doubtful that CBD will be tested for, and as long as the oil is good quality, the levels of THC should be too low to cause any issues.
