There are several techniques for extracting CBD oil from the cannabis plant. The extraction method determines whether the active CBD compound gets processed as a “full spectrum oil” or an “isolate.” A CBD isolate is a pure compound with no other active compounds or cannabinoids at all. A full spectrum oil contains other active plant compounds in addition to the CBD such as CBN (cannabinol) and cannabis terpenes (the part of the plant that gives the plant its aroma), and more.
CBD (cannabidiol) oil is a popular product for everything from pain control to anxiety to promoting sleep. However, with the rise of CBD comes the concern about failing a drug test due to detection of CBD oil. News stories are emerging across the country involving famous sports players, employees of companies, and others who have gotten positive drug screening results for the presence of THC—the psychoactive component of marijuana —even though CBD oil is said to be THC-free.
1. Using Product With THC
When a drug test is performed, the active chemical in marijuana that gets detected in a positive screening is THC. However, most people are under the impression that CBD oil is THC-free.
For instance, if someone who had direct contact with marijuana then touched your hair, you could feasibly receive a false positive on a drug screening that tests your hair.
Inadvertent exposure to marijuana (via secondhand smoke) is unlikely to be enough for a person to get a positive drug test result, but it is possible. Being in a room with heavy pot smokers for several hours may cause the inhalation of enough THC containing smoke to result in a positive test.
Topical products that claim to contain CBD—like shampoos, cosmetics or creams—should not cause any reaction during a drug test because they do not enter the bloodstream. In the case of CBD oils, gummies, teas or transdermal patches, the situation is more complicated. In a test of 84 CBD products obtained online, 18 contained THC.
CBD has taken off as a natural remedy for a variety of ailments. CBD products like CBD oil can be made from either the hemp plant or the cannabis plant, which are closely related varieties of the same cannabis species, Cannabis sativa. CBD products contain a cannabinoid—a chemical—called cannabidiol, which does not make you high. The substance in marijuana that causes a buzz is a different cannabinoid, called THC, or tetrahydrocannabinol.
Factors in CBD Oil Showing on Drug Screen
CBD products can still be problematic, however, when it comes to drug testing. Though drug tests screen for THC, not CBD, many CBD products contain a trace amount of THC which will be detected in your bloodstream during a drug test.
The legality of CBD products can be confusing. CBD products made from certain cannabis plant varieties are legal only in states where marijuana is legal, due to the potential THC content. CBD products made from hemp variety plants are legal throughout the United States as long as they contain less than 0.3% of THC and do not make any medical claims. (A hemp plant is defined as Cannabis sativa that contains less than 0.3% THC.)
If you are concerned that THC in your CBD oil or other CBD product may show up on a drug test, you may be able to reduce the chance of that occurring, though there is no guarantee. Some of the factors that may increase the likelihood of a failed drug test are:
Different types of drug tests have different detection thresholds, but the type you’re most likely to encounter is the “pee test.” To pass a urine drug test, the amount of THC in your body must be below 50 ng/mL. That’s the cutoff recommended federally by the National Institutes of Health and clinically by the Substance Abuse and Mental Health Services Administration, which helps set industry standards for lab certifications.
To hit 50 ng/mL of THC, you’d probably have to consume upwards of 2,000 mg of CBD products that contain 0.3% or less of THC, which is much higher than the average person is likely to take. Even in clinical trials and research studies, people are usually only administered 100-800mg/day.
When it comes to marijuana, drug tests typically only screen for THC — the compound in cannabis that gets you “high” — or one of the compounds created when your body metabolizes it. And by law CBD products can only contain up to 0.3% THC.
How cannabis drug tests work
This story discusses substances that are legal in some places but not in others and is for informational purposes only and not for the purpose of providing legal advice. You shouldn’t do things that are illegal — this story does not endorse or encourage illegal drug use.
First, THC is fat-soluble, so when you ingest it — especially via edibles or a drop of oil under the tongue — it’s absorbed along with other fats and can be stored in your body’s fatty tissue.
So you’re in the clear, right? Not quite. There are two ways you could hit that 50 ng/mL mark.
Drug tests don’t screen for CBD, but that doesn’t mean you’re in the clear.
