Can You Fail a Drug Test After Using CBD Oil?

CBD oil has become extremely popular over the past couple of years. Its emergence has come at a time when medical marijuana is becoming ever more widespread, and people are starting to understand how helpful CBD could be when it comes to treating a variety of different medical conditions. One of the most popular forms of CBD use is through a CBD oil product that can be administered sublingually by holding it beneath the tongue.

One serious issue, however, that will concern a lot of people, is for those who are regularly drug tested at their place of employment. While a lot of people don’t believe in this policy, there are many employers across the world that require their workers to submit to regular drug testing.
The likes of federal employees have mandatory drug testing, but in the private sector it is discretionary, with the individual business deciding if they want to enact such a policy or not. However, it seems that drug testing is becoming more and more popular as time goes on.

In order to be compliant with this type of drug testing, the employer needs to follow the Substance Abuse and Mental Health Services (SAMHSA) guidelines, as this is where they are sound in a legal sense. There will be some sort of an overlap when it comes to the way the test is administered and what level of drug metabolites are found through confirmatory screening and testing.
THC, of course, is the main psychoactive compound that is found in marijuana, and it is what gives the ‘high’ effect. This is why most drug tests are going to look for the presence of THC. If you are undergoing a urine drug testing that looks for marijuana usage, they utilize immunoassay alongside antibodies that can detect the presence of THC, as well as the predominant metabolite of it which is called THC-COOH.

Currently, according to the SAMHSA guidelines, there is a cut-off level when it comes to the positive urine screen, with the immunoassay being at the 50 ng/mL level.
When the reading from the screen is over that number, there will be another test administered, which is called a confirmatory GC/MS test, to confirm that this urine screen is in fact a legitimate result. For this test, there is a cut-off at 15 ng/mL, and it only looks at the 11-nor-THC-COOH metabolite.

Does CBD oil usage show up on this test as a positive result for marijuana usage?

As of now, when testing for THC-COOH using a urine drug screen, there is not much evidence to show that there is a cross reactivity with other types of cannabinoids that are not intoxicating in nature, including the likes of CBN, CBG and CBD. This, of course, is a positive sign for people who stick to the likes of hemp oil and CBD oil.
However, if you are regularly using very high doses of hemp oil product that are rich in endocannabinoids, which would be in the range of between 1000g and 200g of hemp oil on a daily basis, then there is a chance of having a positive test when it comes to the initial urine test. While this would be rare, it would be a false positive result because of the non-THC metabolites, which could potentially react with the test’s immunoassay.
If this happens, the secondary GC/MS test will be negative, and the other types of cannabinoids cannot be detected when it comes to this screen.
For the most part, the reliable and high-quality forms of CBD concentrated hemp oil products are going to have significantly less THC than what would be found when you consume marijuana. It could be anywhere from one tenth to one three-hundredths of the THC content that would be found within marijuana.
Therefore, if a person happened to be consuming between 1000g and 2000g of this type of hemp oil every day, they would be consuming between 3g and 6g of THC. As this is a very significant dosage, there could be a positive result in the urine test, with the range of probabilities being between 11% and 23% of the given assays.
There is certain evidence that shows that the rate of a positive urine test is less than 0.2% when someone is consuming doses of 0.5mg of THC every day as a result of having 3-5 servings of CBD-heavy hemp oil products if they are of a high purity and quality and contain less than 0.1mg of THC. Therefore, this would mean that when compared to marijuana, it would have 400-600 times lower concentration of THC.


To bring everything together, the key takeaway is that, if you are someone who is utilizing a CBD product that is of a high-quality, and if the product is a hemp-based one which has been scientifically vetted at a normal serving size, the chances of you scoring a positive on a urine drug test is going to be very slim.
Having said this, it is very important that you are aware that the use of very high doses could lead to a positive result in a urine test. Of course, this would be proven to be a false positive when the secondary and more accurate GC/MS test has been completed.
It is important that, if you are in a field that has regular drug testing, you are always keeping up to date with the types of regulations your given employer utilizes and that you tailor your use of products to ensure you use ones containing appropriate levels of cannabinoids.
There are, of course, certain products that are completely free from THC, and if they are a trusted brand, this could be an option for you if drug testing is an issue that is keeping you up at night. While CBD oil could provide a lot of benefits for so many people, oftentimes individuals aren’t willing to risk their livelihoods in case they happen to have a positive drug test result from the consumption of these types of products.
