In fact, one study discovered that almost 70 percent of the CBD products sold online were not labeled properly, “causing potential serious harm to its consumers.” The reason for this widespread mislabeling is that CBD products are not strictly regulated by the FDA.
As it turns out, depending on the source of the cannabis that is used to produce the CBD oil, some products do contain traces of THC (including low-quality isolates and many full-spectrum tinctures).
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.
4. Secondhand Exposure to THC
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.
Most CBD products are made from hemp, not marijuana.
Arno Kroner, DAOM, LAc, is a board-certified acupuncturist, as well as an herbalist and integrative medicine doctor. He operates a private practice in Santa Monica, California.
Cannabis is the umbrella term describing hemp and marijuana plants—two different varieties of the cannabis genus. Both marijuana and hemp can be described as cannabis plants; however, it is important to note that they are still two separate plants.
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.
Why did only one test pick up CBN? The tests are known immunoassays — which means they use antibodies to detect drugs. Kroner explained that there are slight differences in the antibodies that test manufacturers use — so it’s possible to get different results.
If you think CBD products are suddenly everywhere, you’re right: There has been an explosion since last year, when Congress lifted a decades-old ban on growing hemp.
What should you do if you use any of these products and have a drug test coming up?
CBD and CBN are two of many chemicals found in cannabis plants. They differ from THC, the source of the marijuana “high.” CBD is present in marijuana but more abundant in hemp — cannabis plants that have little THC. CBN, meanwhile, is a THC derivative.
In most cases, it’s highly unlikely that CBD will show up on a drug test. Usually employment drug tests look for the presence of THC or THC metabolites. Most employers abide by the guidelines set forth by the Substance Abuse and Mental Health Services (SAMHSA), which includes detection for THC but not CBD. Tests generally look for THC but how much and how long THC sticks around depends on what’s being tested.
CBD is a non-intoxicating cannabinoid found in cannabis plants, and some say it provides the benefit of relaxation without THC’s high.
THC and its metabolites can also be detected in the saliva of occasional and chronic users. A 2014 study published in the journal Drug Testing and Analysis looked at cannabinoids in oral fluid and found that THC metabolites were detectable in the saliva of occasional users for one to three days and chronic users for up to 29 days.
What drug tests look for
There is mounting evidence that hair follicle drug testing methods are not able to accurately detect marijuana. Research published in the journal Scientific Reports suggests that the presence of THC and THC metabolites can be transferred to the hair follicles of non-consumers through contact with hands, sweat, or exhaled smoke.
If you prefer CBD oil, tincture, gummies, or other ingestible forms, go with a product made from CBD isolate or crystalline CBD. These use 99% pure CBD so you don’t have to worry about THC or anything else being in there.
To obtain a CBD drug test, an entity would have to pay a testing company to develop a CBD test and to change their testing regimen to include it. When you consider that this non-intoxicating compound won’t get you high or impair your ability at work, there’s really no need for a CBD drug test.
Topical CBD products like ointments, lotions, or balms don’t enter the bloodstream in a way that would be picked up by a drug test. Even if it contains the federally legal amount of 0.3% THC, topicals are still safe as far as drug testing is concerned.
