It is not likely for CBD oil to make you fail a drug test, but there are different forms of cannabidiol (CBD) oil that do contain some THC and you should know which you are taking. First, if you are worried about failing a drug test, or just plain don’t want to have any “high” effects, make sure the CBD product you are using is derived from hemp and not marijuana (there is a difference).

In short, CBD derived from hemp will contain low to zero levels of THC, up to .3%, by law. While this amount is negligible, if a person were to use large quantities, like take a month’s supply in a day, there is a greater chance of not passing a drug test. If you were to take that much, however, you probably also wouldn’t feel very well.

CBD derived from marijuana will likely contain above .3% and thus will cause intoxicating effects, and is also likely to cause a failed drug test. So, be sure to know what type of CBD you are buying, from hemp or marijuana, when purchasing.

There are some forms of CBD which do contain zero THC. For those afraid of failing a drug test due to CBD, read the following as that will help determine which CBD products you can try.

Full- Spectrum CBD vs Isolate

The 2 main forms of CBD products are full-spectrum and isolate. Full-spectrum is a form of CBD product that contains CBD as well as all other matter contained in the plant. This is similar to how eating an orange would give a person Vitamin C, along with all of the other nutrients contained in the orange.

CBD isolate is cannabidiol in its purest form. CBD is isolated from the plant matter and refined to take any additional plant compounds. The final product is a white power that has about 99% cannabidiol. This is similar to taking a Vitamin C tablet instead of eating the orange mentioned above. Both forms are useful, but it’s important to know the difference as CBD isolate does not contain any THC, while a full spectrum CBD product is likely to contain some (less than .3% legally).

You can tell the difference between these two products apart as CBD isolate is a white powder, and thus will cause any product it is infused into to be a clear color, typically. Full-spectrum or whole plant CBD products, especially oils are darker in nature, and thus using this method, you can typically tell between products that claim “full-spectrum” or isolate.

At the end of the day, if you want to make 100% sure to not fail a drug test when taking a CBD product, be sure to take an “isolate” instead of “full-spectrum” or “whole plant.”
