Urine tests for cannabis are common, especially in the workplace. Blood tests are more often used to indicate impairment, for example in cases of driving under the influence. There is the potential for cross-contamination to occur during the CBD manufacturing process, even when THC is present only in trace amounts. There are many differences between marijuana and hemp that relate to CBD oil.
Marijuana contains both THC (the psychoactive component) and CBD, while hemp contains CBD and only trace amounts of THC. Hemp contains many cannabinoids; CBD is just one example. Although tests are being developed to detect CBD metabolites, most employers don't care, they just want to know if you get high. That said, an employer will not be able to tell that you were only using CBD if you fail a drug test for trace amounts of THC.
That's why it's always important to consider the potential risks before using CBD products that contain small amounts of THC. Believe it or not, there are some products on the market without any THC in them at all, making them great options for people looking to pass a drug test. If you need to avoid even trace amounts of THC but still want to consume CBD products, you might consider trying CBD isolate. The drug testing method in question involves a common chemical analysis device called a gas chromatography mass spectrometry machine, or GC-MS.
While there is not necessarily a guarantee that trace amounts of THC in CBD oil will not show up in a drug test, federal workplace drug testing guidelines now include a cut-off value to avoid a positive test for trace amounts of THC. Very small amounts of THC present in the material from which CBD is extracted can enter the CBD oil in high enough quantities to give a positive drug test result. Most of these devices require the drug testing laboratory to add a chemical to the sample to identify traces of illicit compounds, in a process called derivatization. The short answer is that yes, it is possible to take CBD oil that has traces of THC, which you are unlikely to notice.
However, many CBD products contain traces of delta-9-tetrahydrocannabinol (THC), the main active ingredient in marijuana. Secondly, if CBD medicines with traces of THC are used, this must be disclosed in roadside tests prior to any swab testing. For example, an inactive person with high levels of body fat is more likely to retain trace amounts of CBD than those who are lean and exercise daily. The type of drug test you are administered - and the length of time since you last took CBD - could influence whether it is detectable.
Again, you won't fail a drug test for CBD, but you could fail a drug test for any THC residue in that CBD product. This makes it almost impossible to determine if a person is driving under the influence of THC. All over the country there are reports of famous sports players, corporate employees and others testing positive for THC - the psychoactive component of marijuana - even though CBD oil is said to contain no THC. It is a common misconception that CBD and THC are the same; although CBD is a natural supplement, it is possible for THC metabolites to be detected in drug tests.
