Does CBD Oil Have THC? Ask a Pharmacist
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?
The answer: Federally legal full spectrum CBD oil does in fact contain trace amounts of THC. 1
But you may be surprised to learn how important THC is to get maximum benefits from CBD products!
What is THC?
Delta-9 tetrahydrocannabinol (THC) 2 is an intoxicating compound that causes the euphoric effect commonly associated with marijuana intoxication. It can cause mild hallucinations, and it can distort space and time. 3 It’s been the fuel of the American counter-culture since before Woodstock.
Until just a couple of years ago, any amount of THC was 100 percent illegal under federal law. But the passage of the Agriculture Improvement Act of 2018, otherwise known as the Farm Bill, changed the legality of THC to not entirely illegal. This legislation changed the definition of “hemp” to mean any cannabis plant that contains less than 0.3 percent THC. As a result, hemp products with low THC content, like full spectrum CBD oil, are now legal at the federal level. 4
Since the passage of this legislation, hemp-derived CBD products containing trace amounts of THC hit the market hard and fast. So fast that the Food and Drug Administration (FDA) has yet to pass any regulations on hemp-derived CBD products. The CBD industry anticipated the FDA to issue regulations in 2019, but years later Americans are still waiting.
What is CBD?
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
Both CBD and THC are known to interact with the endocannabinoid system, or ECS, a network of cannabinoid receptors in the human body. The cannabinoid receptors in this system interact with these compounds to relay messages between cells to bring the systems of the body into balance, according to preliminary research. This may result in higher quality sleep cycles, an enhanced feeling of well-being, and an improvement on day-to-day aches and pains, according to anecdotal reports. 7
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 have THC?
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
However, these products are considered to have inferior efficacy when compared to full spectrum CBD products, according to anecdotal reports and preliminary research. The trace amounts of THC found in our CBD products is not enough to get you high.
Does CBD Oil Need THC to Be Effective?
Studies show that all cannabinoids work best when they are working together. The combined effect of all cannabinoids together is known as the “entourage effect.” 16 A CBD oil that is labeled as “full spectrum” will have the full range of cannabinoids and provide the best results. 17 So choosing to avoid THC could result in wasting money on an inferior product.
Can I Fail a Drug Test from CBD Oil?
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.
There are new drug tests that can determine that the trace amounts of THC are low enough to be consistent with full spectrum CBD oil use. However, there are still lots of workplaces that do not yet have access to these more sophisticated drug tests. And there are those that don’t care to update their policies regarding CBD use at all.
So the chances are high that you will get a positive drug test result because of CBD oil, regardless of if you try to avoid THC by using broad spectrum products or not. It is best to consult with your company’s HR department to determine if their drug tests can tell the difference between legal CBD use and illegal medical marijuana drug use. When talking to HR about using CBD oils or tinctures, always get their guidance in writing.
CBD Oil Side Effects
CBD can be taken safely in large doses without risk of overdose since it does not affect the circulatory or respiratory systems, and CBD oil doesn’t have intoxicating effects. 18 However, some people may experience negative side effects when they take too much CBD. Research also suggests that many CBD oil side effects could be the result of an interaction with prescription medications. 19
Side effects from too much CBD oil include drowsiness or an upset stomach that could result in diarrhea. 20 Negative side effects can also occur if you are allergic to medical cannabis . One of the most important things to note when taking CBD oil – there is zero risk of overdose from cannabis products, and most side effects can be avoided with careful use.
Is CBD Oil Legal?
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.
It is best to check the cannabis laws for your state (and the state laws of places you may travel to) when seeking any cannabis plant derived CBD product. You also want to purchase from a reputable company that provides third party lab reports to prove the CBD content, and the THC content, of all their products.
How to Shop for CBD Oil
Family-owned Cornbread Hemp is the first CBD oil brand from Kentucky to offer USDA certified organic CBD oils. We are dedicated to providing high quality CBD oil made from Kentucky-grown USDA organic hemp flowers. This is different from many companies who don’t choose organic or source their hemp from overseas, and from companies who use stems and leaves in their extract.
The supercritical CO2 extraction method that many companies employ can produce a harsh, bitter product. Cornbread Hemp chooses to use organic sugarcane ethanol to gently extract cannabinoids from organic hemp flower. This potent extract is mixed with organic MCT coconut oil for optimum bioavailability. As a result, their USDA certified organic CBD oils are smooth and taste great naturally – no need for additional flavors or sweeteners.
Third-party lab test results are available via scannable QR code leading to each CBD product’s certificate of authenticity. The Kentucky laboratory they partner with does a thorough job of testing Cornbread Hemp CBD products for the presence of pesticides, residual solvents, mycotoxins, heavy metals, and microbial contaminants. Lab test results also prove each product’s potency, both for THC content and CBD content. All of Cornbread Hemp’s products are full spectrum and guaranteed to less than 0.3 percent THC.
Conclusion: Does CBD Oil Contain THC?
So, does CBD oil contain THC? It depends. Federally legal full spectrum CBD oil contains no more than 0.3 percent THC. 23 This a high enough percentage that you will reap the benefits when it comes to your rest, stress, and well-being. These trace amounts of THC in CBD oil are not enough to make anyone feel “high.” However, even trace amounts of THC in CBD products may trigger a positive drug test result.
You may think you need to avoid THC for whatever reason; maybe you still think you can pass drug tests with THC free products, or maybe you’re still skeptical of THC use because of its years of legal turmoil. Just keep in mind that the full wellness properties of marijuana derived CBD products can only happen with all of the cannabinoids working together.
For the best results when using CBD oil, look for an organic full spectrum product from Cornbread Hemp. Their legal hemp oil CBD products have the widest range of cannabinoids, including small amounts of THC.

Does CBD Oil Have THC FAQ’s
Can you get high with CBD?
Full-spectrum CBD oils that are made legally with less than 0.3% THC do not have nearly enough THC content to get someone high. THC is the psychoactive compound of the cannabis plant that provides a euphoric sensation, but studies show that CBD actually helps to counteract the psychoactive effects of THC.
Can CBD oil make you fail a drug test?
The highest quality CBD oils contain a full spectrum of cannabinoids, which includes up to 0.3% THC. As a result, anyone taking full-spectrum CBD oil products could be at risk of failing a drug test. Speak with your doctor and HR department first before taking CBD oil if you think you may be drug tested.
What can CBD lab tests tell you?
Most labs test CBD products for the presence of pesticides, residual solvents, mycotoxins, heavy metals, and microbial contaminants. Lab test results also prove each product’s potency, both for THC content and CBD content.

Does CBD Show Up On a Drug Test?

Despite the fact that cannabidiol (CBD) is derived from cannabis—the same type of plant that marijuana comes from—CBD should not show up on a drug test. That said, it is possible.
Drug tests check for tetrahydrocannabinol (THC) because that is the cannabis compound that makes people feel high. CBD products are typically THC-free.
However, CBD products can contain 0.3% of THC by law. In some people, that may be enough to yield a positive drug test result.
This article explains why CBD products may show up on a drug test as THC. It also details what to look for in CBD products so you can prevent a positive drug test.
Does CBD Oil Contain THC?
The active chemical in marijuana that gets detected in a positive drug test screening is THC. Most people are under the impression that CBD oil is THC-free, which is generally true. But not always.
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. This includes low-quality isolates and many full-spectrum tinctures. A full spectrum oil contains other active plant compounds in addition to CBD.
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, but they are two different plants.
CBD is one of many active chemical compounds in cannabis plants. One reason it’s becoming more popular is that it’s said to lack THC.
The primary difference between hemp and marijuana is that hemp is nearly void of THC. In fact, a cannabis strain must contain less than 0.3% THC to be classified as hemp. This is why hemp can be legally sold in various products.
Most CBD products are made from hemp, not marijuana.
There are many distinctions between marijuana and hemp that relate to CBD oil. Marijuana contains both THC (the “high”-inducing element) and CBD. Hemp contains CBD and only trace amounts of THC.
Hemp also contains many cannabinoids, which is a name for the compounds found in cannabis. CBD is only one example.
There are several techniques for extracting CBD oil from the cannabis plant. The extraction method determines whether the CBD oil is an “isolate” or a “full-spectrum oil.”
A CBD isolate is a pure compound with no other active compounds or cannabinoids. The full-spectrum compounds may include other active chemicals, such as cannabinol and cannabis terpenes (the part of the plant that gives the plant its aroma).
Study of CBD Oil
While some CBD oils claim to be isolates, they may be full-spectrum oils and actually contain more cannabinoids (such as THC) than they claim.
A study conducted at the internationally known Lautenberg Center For Immunology and Cancer found that CBD was more effective at treating inflammation and pain when used with other cannabis plant compounds.
These compounds were derived from a full-spectrum product rather than a CBD isolate product alone. This is one reason that full-spectrum products (those containing THC) are popular.
However, the distinction between full-spectrum oils and isolates makes all the difference if you are being tested for drug use.
Reasons for Failing a CBD Drug Test
There are several common reasons a person can test positive for THC after taking CBD.
Using Product With THC
The most common reason for a failed CBD drug test is that a person is using a CBD oil product that contains THC. This may be a full-spectrum product. Sometimes, though, it could be a low-quality isolate product that contains a small amount of THC.
Although most manufacturers claim their products do not contain THC, this is not always the case.
Cross-Contamination of THC
Very small amounts of THC present in the material that CBD is extracted from can get into the CBD oil in high enough amounts to result in a positive drug test. This scenario may be more likely to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal.
Mislabeling of Products
CBD oil extracted from hemp is not supposed to contain more than 0.3% THC. However, it’s not uncommon for sellers to mislabel their products as THC-free hemp when, in reality, it’s a low-quality oil extracted from marijuana. And marijuana does contain THC.
In fact, one study discovered that almost 70% of the CBD products sold online were mislabeled. This caused “potential serious harm to its consumers.” The reason for this widespread mislabeling is that CBD products are not strictly regulated by the Food and Drug Administration (FDA).
Secondhand Exposure to THC
Inadvertent exposure to marijuana (via secondhand smoke) is unlikely to be enough for a person to get a positive drug test result. But it is possible. Being in a room with heavy pot smokers for several hours may cause the inhalation of enough THC-containing smoke to result in a positive test result.
A more likely secondhand exposure scenario is a positive marijuana hair test. This results from direct contact with marijuana paraphernalia or from another person having THC on their hands.
For instance, say that 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.
CBD Oil Breakdown in the Digestive System
Some sources report that in rare cases, false positive test results have come from CBD oil that breaks down into very small amounts of THC in the stomach. Other studies, however, have refuted this finding.
The conclusion is that it’s still theoretically possible for traces of THC to be present in stomach acid when “less-purified CBD productions” are ingested.
How to Avoid a Positive CBD Drug Test
If you take CBD oil, you can take steps to try to prevent failing a drug test:
- Do thorough research to ensure the CBD product you’re using is pure and that the company is legitimate.
- Look for manufacturers that have been accredited by the Better Business Bureau.
- Ensure that the CBD oil is an isolate product extracted from a viable industrial hemp supply. It should not be a low-quality tincture.
- Ask questions about product processing techniques and the possibility of cross-contamination.
- Avoid secondhand exposure to marijuana use via pot smoking or hair contact from THC users.
CBD oil is usually marketed as THC-free, but that’s not always the case. Full-spectrum CBD oils contain other cannabinoids, which may include THC. Isolate products may be contaminated with THC, as well.
You have to be proactive to avoid failing a drug test if you’re taking CBD oil. Most important: Ensure that you’re using a pure product made by a reputable company.
A Word From Verywell
In theory, getting a false positive on a drug test from CBD oil should be relatively impossible from pure CBD oil containing less than 0.3% THC. However, because CBD oil is not well regulated, there is no guarantee that a product contains pure CBD oil or that its concentration is safe or effective.
Use the utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo a drug screening.
Frequently Asked Questions
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.”
Yes. If the products contain THC, you could test positive. If you know you’ll need to take a drug test, avoid full-spectrum CBD products that may contain small amounts of THC. Be sure you purchase products from a reliable source. And be wary of online retailers; researchers have found that 21% of online CBD and hemp products were mislabeled.
Drug tests do not typically measure CBD. Most tests check for THC, the psychoactive component in marijuana. Depending on the frequency of use, THC can be picked up on a test anywhere from a few days for a single use or over a month for heavy daily pot smokers.
CBD edibles take about 30 to 60 minutes to start to take effect. They last five to six hours, depending on your metabolism and dose. A CBD edible may show up on a drug test as THC metabolites for three days. However, if you frequently take CBD edibles, it can take up to 15 days to have a clean urine test.
The FDA strongly advises against taking CBD or THC products while nursing. Cannabis products can be excreted through breastmilk and are not safe for the baby. Cannabinoids can stay in your milk for up to six days, so “pumping and dumping” may not be a good option.

A better way to feel better.
Our high-quality hemp-based CBD products are designed to help you live a balanced while feeling your best.
Do you know what’s in your CBD oil? According to info recently released by the FDA, they found that more than half of the CBD products they reviewed were inaccurately labelled, in many cases containing significantly more or less CBD than indicated on the packaging. So, how exactly do you know what you’re getting?
Cannabis products produce over 100 cannabinoids, but CBD (cannabidiol) and THC (tetrahydrocannabinol) often receive the most attention. CBD products have become widely available after the 2018 Farm Bill legalized hemp-derived products in the United States, and due to the calming and balancing effects of CBD, it’s become a staple of wellness and self-care routines.
When many of us look to incorporate CBD into our lives—whether to help quiet an anxious mind, improve sleep, or manage pain—a common question is “so exactly how much THC is in CBD oil?” Many of us have different reasons for asking this question. While some are interested in the incorporation of THC in CBD oil, some may have other reasons for avoiding it. The short answer is CBD oils must contain less than 0.3% of THC to be considered federally legal, but the precise amount of THC present, if any at all, depends on the type of oil.
Let’s delve a little deeper into how much THC is in CBD oils, the three main types you’ll see out there, and how to determine what a high-quality product is.
While all federally legal CBD oil products must contain less than 0.3% THC, it’s important to know the three common types of CBD to determine what will provide you with the highest benefit. CBD products are available in three forms:
Full-spectrum CBD oils contain all compounds which naturally occur in the hemp plant they were extracted from. These oils will include other compounds such as terpenes and flavonoids which give the oil its unique scent and flavor and also provide greater benefits when utilized together.
When multiple cannabis compounds are integrated, the benefits and effects are enhanced. This phenomenon, called the entourage effect,suggests that when CBD, THC, other cannabinoids and terpenes are all taken together they become more effective and provide greater benefits than when taken alone.
While CBD oil is typically not intended to be a treatment for any diseases or disorders, it’s believed that synergistic interactions may be present between cannabinoids and terpenes. While more research is needed to fully understand this synergistic effect, many consider full-spectrum CBD to be much more effective.
Similar to full-spectrum CBD, broad-spectrum oils and products contain additional compounds found in the hemp plant, including terpenes and other cannabinoids. However, broad-spectrum is further refined to remove THC. Therefore, while broad-spectrum CBD products are less likely to contain THC, many question whether or not the entourage effect is as strong without the small amount of THC contained in full-spectrum CBD.
CBD isolate is exactly what the name implies—it’s pure, isolated CBD, meaning it doesn’t contain any other compounds from the cannabis plant, such as other cannabinoids, flavonoids or terpenes. It doesn’t contain any THC and is thought to be less effective due to no benefits provided from the entourage effect.
It’s important to choose a product from a company that is transparent about their testing practices for THC levels because otherwise you may not know exactly how much is in your CBD oil—and not every CBD company does this. Always ask for a Certificate of Analysis to ensure you’re buying a product that does have less than 0.3% THC.
Certified third-party testing ensures purity and consistency of the product and tests for aspects such as cannabinoid potency, terpene potency, pesticides, herbicides, heavy metals, microbiological contaminants, and residual solvents.
There should never be more than 0.3% of THC in CBD oils to be considered federally legal. However, even with testing and low levels, some people will respond differently and possibly be more sensitive to how much THC is present just like with how caffeine affects different people differently. While there are plenty of CBD oils available from hundreds of CBD companies in the United States, not all CBD oils are created equal.
Here’s what to look for when choosing a CBD oil:
Safety and Quality: CBD companies should include third-party testing for safety and quality.
Extraction Method: The current industry standard is the CO2 extraction method, which uses pressurized carbon dioxide to extract CBD from the hemp plant.
Ingredients: Always check that the CBD oil is clearly labeled and doesn’t contain added chemicals, fillers, or byproducts.
Concentration: Opt for products with higher concentrations listed by per dose or per bottle. CBD oils with more than 60 MG per dose will provide the greatest benefit.
Type: full- and broad-spectrum CBD oils offer the full range of health benefits.
