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.
However, the distinction between full spectrum oils and isolates make all the difference if you are being tested for drug use.
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.
5. CBD Oil Breaks Down in The Digestive System
If you take CBD oil, there are measures you can take to try to prevent failing a drug test.
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.
What are the odds that CBD oil users will test positive when subjected to illicit drug screenings, and what can be done to prevent it?
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.

While CBD isolate might in some ways function as a more potent or concentrated form of CBD, it may be less effective since isolate does not metabolize in your body alongside the other potentially important cannabinoids and terpenes. While some prefer the peace of mind of knowing there’s nothing but CBD in their oil, gummies, or tincture, there’s scientific evidence that consuming full-spectrum products, with all the goodies from the plant, delivers better results via the entourage effect.
While there isn’t necessarily a guarantee that the trace amounts of THC in CBD oil won’t show up on a drug test, you really don’t need to worry about it. If you want to be completely sure that your CBD oil won’t result in a positive drug test, seek out raw CBD oil, CBD distillate, or other pure CBD products.
If you’re interested in benefiting from the potential entourage effect when combining THC and CBD, begin with high-CBD/low-THC cannabis products. Check the ratio of CBD to THC, expressed on the label as something like 10:1, 5:1, 1:1, etc. It may take a bit of experimentation to find the ratio you prefer. It’s possible that CBD works better for some uses, and some people, in conjunction with THC.
So for these consumers, the question inevitably arises: Do CBD products contain THC?
It’s a question asked more frequently than ever, as CBD formulas are popping up in spas, large retailers, coffee houses, online shops, and major pharmacies across the country.
Both cannabinoids bind to the body’s CB1 receptors. THC activates the CB1 receptor, while CBD inhibits it. Trace amounts of THC in CBD products are very unlikely to exhibit any of its effects relative to CBD.
Yes, CBD is legal under federal law so long as it has small amounts of THC, no more than 0.3 percent. 21 However, cannabis laws are constantly evolving at a rapid pace at the state level. At least 36 states have legalized marijuana for medical use by registered patients with prescriptions. At least 11 states have legalized marijuana for recreational use. 22 But there are some states that aren’t even on board with CBD legalization.
Since CBD products are becoming more prevalent in mainstream wellness supplements, some companies have implemented CBD Drug Test guidelines. These suggest a cutoff amount where THC content can be admissible in negligible quantities.
CBD and THC interact with the ECS in different ways. THC more commonly affects CB1 receptors in the brain, hence the feelings of “getting high.” 8 And CBD tends to bond with CB2 receptors elsewhere in the body. Because of this, CBD has many different potential applications 9 and can be used in tinctures, capsules, edibles, and lotions.
Does CBD Oil Need THC to Be Effective?
Any legal CBD product labeled “full spectrum” will contain THC in trace amounts. 13 There are also CBD products labeled “THC-free,” such as “broad spectrum,” and “CBD isolate.” 14 Broad spectrum hemp products have the THC removed, leaving it with only CBD and a few minor cannabinoids. CBD isolate products contain just the single CBD compound by itself. 15
THC and CBD are just two of nearly 150 cannabinoids found in the cannabis plants. 5 Cannabidiol (CBD) is the main compound thought responsible for many of the potential health benefits cannabis plants may provide. 6
When people want to try CBD oil, they may have a lot of questions about THC content. Thanks to the stigma the government placed on marijuana in the early 20th century, many people remain wary when it comes to THC exposure. So naturally people want to know: Does CBD oil contain THC?
