Cannabidiol (CBD) Oil and Drug Tests
Will CBD Oil show up on Drug Tests?
Although cannabidiol (CBD) is an inactive compound with no psychoactive effects, it is possible that using cannabis-derived CBD oils and other CBD products could theoretically lead to a positive drug test. CBD oil can also be made from hemp, in which case, (Check them out on Amazon) hemp-derived CBD products are legal in any state, can be purchased over-the-counter, and do not require a medical marijuana prescription or other special authorization from the state.
Most cannabis-based CBD products are in the form of oil-based capsules or extracts either taken orally as a supplement or used topically as a lotion. However, new CBD products are constantly arriving on the market.
The United States Food and Drug Administration (FDA) has repeatedly warned companies who manufacture CBD oil to improve incorrect labeling. CBD oil manufacturers have also been criticized by FDA for making medical claims that remain unsubstantiated by the scientific literature. Therefore, it can be difficult to have complete confidence that the CBD oil being sold on the medical marijuana market is in fact what it claims to be. Therefore, individuals who are concerned about having positive drug tests while using CBD oil may want to consider transitioning to a hemp-based CBD oil or taking regular drug tests on their own, because it can be impossible to know what the true component profile of cannabis-based CBD oils are.

What are some different types of drug tests that screen for compounds found in marijuana and other drugs?
There are many types of drug tests that enable detection of compounds in blood, urine, hair follicles, and even perspiration. These different tests can test directly for the drugs of interest, metabolites, and other indirect or direct markers, and have various levels of sensitivity and specificity. However, certain vitamins and minerals, as well as a few prescription and over-the-counter medications can interfere with various types of drug tests and either mask positive results or cause false positives. Therefore, the gold standard, in drug testing is the application of an analytic chemistry technique, Gas Chromatography-Mass Spectrometry (GCMS), to test samples to enable the identification of compounds with very high accuracy.
How do drug tests for marijuana work?
There are many different ways to test for marijuana, which is easy to detect by urine, hair, or saliva tests. Cannabinoids are fat-soluble and can be stored in the body’s fat cells, and therefore will be detected on one’s body and in one’s system for days or even weeks after use. The concentrations of marijuana detected by urinalysis, hair follicle analysis, or saliva tests can distinguish between a person who has been actively smoking or consuming marijuana and a person who has spent some time in the same place as a marijuana smoker.
Can CBD oil show up on a drug tests?
Hemp-based CBD oil can show up on drug tests, especially in cases where a very large amount of the hemp-based product has been used (e.g., consumed or applied topically). However, gas chromatography-mass spectrometry (GC-MS), a more expensive analytic method, can distinguish between using hemp-based products such as hemp-based CBD oil, which is not illegal, and cannabis, which is a Schedule I Controlled Substance according to the Drug Enforcement Administration. In a study by Fortner and colleagues (1997), participants screened positive for marijuana after eating a hempseed bar, but GC-MS did not give a detectable level of marijuana in their systems.
It is important to note that CBD oils are derived from flowers, leaves, and stalks of the marijuana or hemp plant. Therefore, cannabis-derived CBD oil is indeed derived from marijuana and could lead to a positive result on a drug test due to the trace presence of THC in the cannabis-derived product. This positive finding would likely be substantiated by GC-MS.
When and for how long does CBD oil show up on drug tests?
This depends, but marijuana is slow to leave the body and unlike alcohol, which is partially water-soluble, marijuana is fat-soluble and therefore not immediately excreted. Hemp-based CBD oil should not contain some of the psychoactive chemicals present in marijuana and should ultimately be able to be confirmed as a false positive by GC-MS. However, cannabis-based CBD oil could contain trace amounts of marijuana, and if that is indeed the case, the GC-MS test would remain positive for days or weeks.
Marijuana can be stored in fat cells for a long time. People with a high body fat percentage could potentially store the compounds present in marijuana in their adipose tissue for a longer time than individuals with a lower amount of body fat.
