cbd hemp oil drug test

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:

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.

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

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.

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.

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.

CBD will not show up in a drug test because drug tests are not screening for it. CBD products may well contain THC, however, so you can fail a drug test after taking CBD products. If you take CBD oil, you should plan accordingly if your work or activities require you to undergo drug testing.

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.

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.

1. Using Product With THC

A more likely secondhand exposure scenario is a positive marijuana hair test, resulting from direct contact with marijuana paraphernalia or from another person having THC on their hands.

There are many distinctions between marijuana and hemp that relate to CBD oil. Marijuana contains both THC (the psychoactive component) and CBD, whereas hemp contains CBD and only trace amounts of THC. Hemp contains many cannabinoids—CBD is only one example.

Drug tests look for tetrahydrocannabinol (THC), which is the element in marijuana that causes a high. CBD oils can have trace amounts of THC even if they're labeled “THC-free.” The FDA does not regulate these products, and mislabeling is common.

She and her colleagues at the University of Utah Health Sciences Center in Salt Lake City spiked three batches of urine samples with CBD, CBN and two other cannabis compounds — cannabichromene and cannabigerol.

It all points to the importance of taking “cross-reactivity” into account when a drug screening test comes back positive, Kroner said.

A 2017 study found that about seven out of 10 CBD products did not contain the amount of cannabidiol stated on the label. And about one in five contained THC.

Given that context, it’s important to understand how the compounds interact with drug screening tests, said Grace Kroner, lead researcher on the new study.

The simplest course is to refrain for a while, according to Kroner. But she also advised being up front about your CBD or CBN use — or any supplement use, for that matter — so that your test results can be interpreted in that light.
