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.
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.
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.
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.
How Long Does CBD Stay In Your Saliva?
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.
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.
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:

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.
Different drug tests have different cut-off levels. Legally, hemp products can contain up to 0.3% of THC.
And in 2018, the CDC released a report that found that more than 50 people in Utah were poisoned by CBD products that actually contained synthetic marijuana commonly known as Spice and K2.
First, THC is fat-soluble, so when you ingest it — especially via edibles or a drop of oil under the tongue — it’s absorbed along with other fats and can be stored in your body’s fatty tissue.
Second, there’s a good chance that the CBD product you’re using contains more than the .3% THC legally allowed. In fact, when Penn Medicine researchers bought CBD products online and then analyzed their ingredients, they found that about one in five contained up to 6.4 mg/ML of THC — high enough to cause impairment.
Drug tests don’t screen for CBD, but that doesn’t mean you’re in the clear.
Why CBD might cause you to fail a drug test
So you’re in the clear, right? Not quite. There are two ways you could hit that 50 ng/mL mark.
When it comes to marijuana, drug tests typically only screen for THC — the compound in cannabis that gets you “high” — or one of the compounds created when your body metabolizes it. And by law CBD products can only contain up to 0.3% THC.

To hit 50 ng/mL of THC, you’d probably have to consume upwards of 2,000 mg of CBD products that contain 0.3% or less of THC, which is much higher than the average person is likely to take. Even in clinical trials and research studies, people are usually only administered 100-800mg/day.
Topical CBD products like ointments, lotions, or balms don’t enter the bloodstream in a way that would be picked up by a drug test. Even if it contains the federally legal amount of 0.3% THC, topicals are still safe as far as drug testing is concerned.
When consuming pure CBD, there is evidence you’ll be missing out on some health goodies conveyed by the entourage effect if you chose a full- or broad-spectrum CBD product instead. But it’s the only way to be certain there’s no THC in your CBD, and the only way to buy CBD in states with highly restrictive laws.
CBD is a non-intoxicating cannabinoid found in cannabis plants, and some say it provides the benefit of relaxation without THC’s high.
How to read a CBD label
Upon inhalation, active THC can be found in the bloodstream within a matter of seconds and can be detected in plasma for several hours, depending on the frequency of use and dosage. According to a 2004 review published in the journal Therapeutic Drug Monitoring, the plasma concentration of THC peaks just three to eight minutes after inhalation and then decreases quickly with a half-life of about 30 minutes. The study claims that THC is detectable in blood for about five hours, but the THC metabolite THC-COOH has a detection time of up to 25 days.
