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.
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 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.
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 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.
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).
In a study conducted by researchers from the Lautenberg Center, researchers discovered that CBD was more effective for treating inflammation and pain when used with other cannabis plant compounds derived from a full spectrum product over a CBD isolate product alone. This is one reason that full spectrum products (those containing THC) are popular.
Breakdown of Cannabis
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.
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.
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.
The difference is primarily a chemical one, with their structures being different, however, both CBD and THC (the main active component of cannabis) are members of the cannabinoid family. CBD does not have the same psychoactive effect as that of THC. The same plant can produce both chemicals, because they are both derived from CBGA. The CBGA will then convert into CBD or THC, dependent on the enzyme that acts on it, with THCA synthase turning CBGA into THC, and CBDA synthase converting it into CBD.
It is noted that CBD extracts from the marijuana plant that contains high levels of THC are illegal to consume or use.
Is CBD marijuana or hemp?
That said at DNA Legal when testing hair we also test THC-COOH which is only produced through the consumption of THC and not CBD.
Yes, it is possible, but it’s unlikely. Certain impure CBD products may contain trace amounts of the other cannabis compounds, including THC. In hair, the heavy repeated consumption of highly impure CBD above 200mg/day may result in the detection of trace amounts of THC.
The market in the UK is worth around £300m a year and that figure is rising, especially as the number of CBD oil users is now in the hundreds of thousands. These figures are expected to triple over the next 5 years according to Savills. Because of the surge in demand for CBD, pharmaceutical companies are entering the industry and attempting to improve the education, knowledge, and reputation of CBD products to maximise their profits.
