Does CBD Hemp Oil Cause You To Test Positive On a Drug Screen Test?

05 June 2017 by Austin Nordyke

When it comes to drug testing in the work force, drug testing is mandatory for federal employees and a reality that many people go through throughout their jobs, or when applying for a job. Many private sectors are also leaning towards drug tests screening processes to ensure their works are not on illicit drug use.

With this in mind, let’s look at how a drug test works. Employers, mandatorily, follow the same guidelines for drug testing, SAMHSA (Substance Abuse and Mental Health Services). The reason this is an across the board guidelines is because it puts all employers on a stable legal ground to cover all of their bases.

How does testing positive for THC work?

THC is recognized as the substance within marijuana that is responsible for the many psychoactivity and euphoric effects of users. A routine drug tests consists of immunoassay and its main metabolite (11-nor-delta9-caboxy-THC) with antibodies that are made to be detected. The cut off level, set by SAMHSA, to test positive for immunoassay is 50ng/mL. If the immunoassay screen comes back positive at the > 50 ng/ML level, a secondary test known as the Gas Chromatography/Mass Spectrometry (GC/MS) is performed. GC/MS has a cutoff level of 15 ng/mL and is only confirmed to the 11-nor-THCCPPH metabolite.

Good News For CBD Oil Consumers

The drug test for THC-COOH is known to have little if any cross-reactivity to other cannabinoids that are not psychoactive. This means you can include CBD (Cannabidiol), CBN (Cannabinol), CBG (Cannabigerol) and other cannabinoids on the list that will not show up as positive for drug use.

With this said, at times individuals using extremely large doses of cannabinoid-rich hemp oil products may test positive for the first phase of the urinary screening. Although very unusual and rare, the screen test, in most cases, comes back as a “false positive” due to other non-THC compounds. These compounds end up cross-reacting with the immunoassay.

If the first phase of the screening process test positive, do not fear because the GC/MS test will come back negative because CBD and other cannabinoids cannot be detected by the more precise, GC/MS screen.

When it comes to reliable and high-quality CBD-rich hemp oil products, they contain minimal doses of THC, unlike marijuana. In comparison to marijuana, CBD oil contains anywhere from 1/10th to 1/300th of THC. Therefore, for you to even consume 3-6mg of THC, you would have to consume 1000-2000mg per day of hemp oil. This overly large dose of hemp oil may result as a positive detection of THC, up to 11% to 23% of assays.

In retrospect, other data has demonstrated that daily doses of 0.5mg of THC from 2-5 servings of CBD-rich hemp oil can result in < 0.2%. The good news is, most servings of high-quality and high purity CBD oil products, such as Inspirit Hemp, contain well below 0.1mg of THC and in turn, have over 400 times less THC than marijuana products.

The Answer Is No

The conclusion is that NO, if you use high-quality, scientifically vetted hemp-based product at the suggested serving size, it is highly unlikely that you will test positive for THC-COOH and/or THC. This does not mean you can over exceed your doses as extremely high doses, at times, may result in a positive screen test, which, shortly thereafter, would show to be false via GC/MS.

If you find yourself in the position of a drug test, or are applying for a job, it is utterly important to be cognizant of the specific regulations implemented by your employer so you can better adjust your cannabinoid consumption.
