CBD Oil, Drug Testing, and The Endocannabinoid System

So, you’ve tried CBD once or twice and you love it! You want to start using it instead of your ibuprofen and melatonin, but you are worried about your jobs random drug screenings. Well, let me tell you something, you can have the best of both worlds! As CBD becomes more and more common in everyday products, more and more people are moving to giving the ancient cannabinoid a try.

Yet, many are worried that it may cause them to fail a drug test. While certain forms of CBD can lead to failing a drug test for THC metabolites, most will not as the THC levels are too low to cause a buildup of metabolites in your fat cells. Preliminary studies have shown that CBD will not cause a failed drug test as long as it is pure, meaning that it is a CBD Isolate product that contains no other cannabinoids other than CBD.

Full-Spectrum CBD Oil & Products

Other products that contain other forms of CBD Oil such as Full-Spectrum CBD Oil (FSO) can cause a positive for THC metabolites. This is because FSO contains all of the cannabinoids in the hemp plant including trace amounts of THC (below 0.3%). Taking excessive amounts of FSO will make you high, so definitely be careful when dosing you sneaky Full-Spectrum CBD user you.

Broad-Spectrum CBD Oil & Products

Broad-Spectrum CBD Oil and products are another form of CBD that can cause you to fail a drug test, not because of THC though. Broad-Spectrum CBD Oil and products contain all of the cannabinoids in the hemp plant except THC which is removed through further processing.

The reason Broad-Spectrum CBD products can cause a failed drug test is because of Cannabinol, also known as CBN. CBN is a derivative of THC whereas CBD and THC are both derivatives of CBG (Cannabigerol). CBN is also the next best cannabinoid for sleep after THC due, in part to its affinity for both cannabinoid receptors.

The Endocannabinoid System

Are you starting to see the best of both worlds yet? No? Then, please take some CBD Isolate (job depending) and continue reading this blog! Do you know how cannabinoids work? No? It’s called the Endocannabinoid System, a vast system of receptors all throughout your body.

Cannabinoids work by interacting with your endocannabinoid system, effectively maintaining your body’s homeostasis which helps regulate your mood, immune system, sleep, inflammation, and pain management.

Within this system, there are two types of receptors, the CB1 and CB2 receptors. The CB1 receptors are located in the brain and the CB2 receptors are located all throughout the body.

THC and CBN bind to both the CB1 and CB2 receptors and therefore produce psychoactive (heady) effects as well as physiological (body) effects, although CBN produces minimal psychoactive effects. CBD and CBG bind to only the CB2 receptors and therefore only produce physiological effects with no head high.

All of this goes to say that if you consume products with THC and/or CBN you may fail a drug screening but if you consume products with only CBD Isolate and/or CBG Isolate then there is almost no chance of failing a drug test. It’s really as simple as that.

Now, you can take this information and use it to safely make the correct decision on CBD products that you want to use in your everyday life, but if you have any further questions, please don’t hesitate to email us at
