Will organic CBD oil show up on a drug test?

Will CBD show up on a drug test?

Workplace drug testing and road-side drug testing is now a reality, especially for people who work with vulnerable adults, children, dangerous industries, and government employees.

The answer to the question of whether you will test positive if you use a high-quality, low THC CBD hemp oil is, in a nutshell, “Not unless you use way too much of it”. Let’s look at the facts and see why:

CBD is a cannabinoid, but it differs from THC. Remember? We wrote about this before. THC is what makes you high and the CBD oil that Fleet and Flower sells has a miniscule amount of THC that makes it legal for us to sell. 

THC is the  cannabinoid that is targeted in drug tests. These tests look for the metabolic products of THC and begin with a simple urine test sample.

Science part

The test uses antibodies to detect THC and the metabolite it produces, known by the rather complicated name of ‘11-nor-delta9-caboxy-THC (THC-COOH)’. If initial tests find that you have more than 50 Nano grams (ng) of these substances in your urine, a Gas Chromatography / Mass Spectrometry (GC/MS) test is carried out to confirm the result. This test targets the 11-nor-THCCOOH metabolite and aren’t sensitive to other cannabinoids including CBD. There is no such thing as a CBD drug test because CBD is not a drug.

Trace amounts of THC in CBD oil. If you’re using the best CBD oil, it will contain only tiny amounts of THC and you’d have to use more than 1000-2000 mg of the oil every day in order to test positive in initial screening tests. When this happens and the second test is run, the results of the first test will likely turn up as a ‘false positive’. Remember, the initial test isn’t all that sensitive or accurate, and that’s why the second test is run if the first one picks up a positive result.

Bear in mind that the THC concentrations in hemp oil are nowhere near enough to have any effect on you: hemp plants generally contain only a tenth to one three-hundredth of the THC that marijuana plants contain. An extremely high level of consumption of more than 2000mg daily would thus deliver between 3 and 6 mg of THC and this may cause false positive initial tests in 11 to 23 percent of cases.


Most people use a lot less than that and would only consume a maximum of 0.5mg of THC along with their CBD in that case, there is a lower than 0.2 % chance of a positive preliminary screening result. This is perfectly logical since a good CBD oil contains 400 to 600 times less THC than cannabis.

It’s extremely important to use a CBD source that tests the effective cannabinoids presence in the Hemp Oil. And this process is the organic CBD oil that Fleet and Flower's uses.

Yeah, but what about the Entourage Effect?

 “Entourage Effect”. The Entourage Effect is the synergy observed between various marijuana compounds. Ironically alcohol which is common and damaging doesn’t require any test, but this plant does.

As we wrote earlier, you would want to be smoking huge amount of CBD vape oil to test positive. THe organic CBD vape oil, grown in Ireland, that we sell has a 0.2% concentration of THC which is why it is legal to sell.

Use your best judgement if planning to be tested. Oh and Always consult a medical doctor before modifying your diet or using any new product. ANd again, Fleet + Flower is for over 18s only - to read and or buy from ya gotta be 18+
