will cbd oil test positive for thc

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.)

Factors in CBD Oil Showing on Drug Screen

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:

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.

THC can be detected in a urine test for up to 15 days, depending on how often and how much you use. It leaves the bloodstream in about five hours, but substances your body makes from THC (THC metabolites) can show up for as long as 7 days. CBD tends to stay in the bloodstream from 2 to 5 days, depending on dosage and frequency. If you have been using CBD for a while, it can stay in your body for up to 30 days or more.

And, while some studies have suggested drug testing at work is a thing of the past, this is not the case for all jobs. Some jobs, as well as criminal justice and addiction treatment proceedings, among others, still require drug testing.

A team at Johns Hopkins Medicine conducted a study in which six individuals administered pure CBD, both orally and using a vaporizer, as well as inhaled vaporized CBD-dominant cannabis (containing 0.39% THC) on separate occasions.

How We Drug-Test For Cannabis

And this is what Johns Hopkins Medicine researchers set out to do in recent months, publishing their findings at the Journal of Analytical Toxicology this week.

In his and his colleagues’ opinion, these results have important implications for consumers of CBD products.

“Conventional urine drug testing for cannabis targets a common metabolite of THC called THCCOOH (THC is the primary psychoactive component of cannabis). Importantly, many CBD-dominant products contain low levels of THC, including hemp-derived CBD products which can legally contain up to 0.3% THC,” he said. “There is a need to understand whether the use of CBD products, with and without low levels of THC, can impact drug testing for cannabis given their growing availability and increased interest in CBD for therapeutic purposes.”
