TL;DR:
- Hemp oil does not produce a high because it contains no or negligible amounts of THC. Hemp seed oil, pressed from seeds, is THC-free and used for nutrition and skincare without psychoactive effects.
Hemp oil is defined as a non-psychoactive plant extract that does not produce a high. The question of whether hemp oil will make you high has a straightforward answer: no. Hemp oil contains negligible amounts of THC, the cannabinoid responsible for intoxication, and in most cases contains none at all. Understanding why requires a closer look at what hemp oil actually is, how it differs from CBD oil and marijuana, and what the latest research tells us about its effects on the body.
Will hemp oil make you high? What the science says
Hemp oil does not cause intoxication. The compound responsible for the cannabis high is delta-9 tetrahydrocannabinol, commonly known as THC. Hemp oil, particularly hemp seed oil, is produced by cold-pressing hemp seeds and contains no cannabinoids whatsoever, including no THC and no CBD. Without THC, there is no mechanism in the product to produce a high.
The confusion often arises because hemp, CBD oil, and marijuana all come from the Cannabis sativa plant. They are not the same product. Hemp seed oil comes from the seeds alone, which carry no psychoactive compounds. CBD oil is extracted from the flowers, leaves, and stalks of the hemp plant and may contain trace amounts of THC, but still far below any intoxicating threshold.
Federal law defines hemp as Cannabis sativa L. with a delta-9 THC concentration of no more than 0.3% by dry weight. That limit exists specifically to prevent intoxicating effects while permitting industrial and wellness uses. Marijuana, by contrast, contains THC levels high enough to cause significant psychoactive effects. The gap between 0.3% and the concentrations found in recreational cannabis is substantial.
What is hemp oil and how does it differ from CBD oil?
Hemp oil is a broad term that covers two distinct products, and the distinction matters enormously when you are asking whether it can get you high.
Hemp seed oil is pressed from the seeds of the hemp plant. The seeds contain no cannabinoids, so the resulting oil is entirely free of THC and CBD. It is used in cooking, skincare, and nutritional supplements for its fatty acid content, not for any effect on the endocannabinoid system.
CBD oil (also called hemp extract or hemp-derived CBD oil) is extracted from the flowers, leaves, and stalks of the hemp plant. It contains cannabidiol (CBD) as its primary active compound and may contain trace amounts of THC depending on whether it is full-spectrum, broad-spectrum, or isolate.
The key differences at a glance:
- Hemp seed oil: Cold-pressed from seeds, cannabinoid-free, used in nutrition and cosmetics
- CBD oil (full-spectrum): Extracted from the plant, contains CBD plus trace THC (up to 0.3%)
- CBD oil (broad-spectrum): Contains CBD and other cannabinoids but THC is removed or undetectable
- CBD isolate: Pure CBD only, no other cannabinoids
- Marijuana-derived oil: Contains high THC concentrations and is psychoactive
When a product is labelled simply as “hemp oil,” check whether it means hemp seed oil or a hemp-derived CBD extract. The label should specify the extraction method and cannabinoid content. Cold-pressed hemp seed oil labelled cannabinoid-free carries no psychoactive risk whatsoever.
Why hemp oil will not make you high: THC content explained
THC is the only cannabinoid that produces the classic cannabis high. It binds directly to CB1 receptors in the brain, triggering the euphoria, altered perception, and impairment associated with marijuana use. CBD does not produce this intoxicating effect and does not cause euphoria or impairment, even at higher doses.
Hemp seed oil contains no THC at all. Even broad-spectrum CBD oil, which is derived from the hemp plant rather than the seeds, has THC removed to undetectable levels. Full-spectrum hemp oil may contain up to the legal 0.3% THC limit, but trace THC at these levels does not cause intoxication in typical doses. Any reported cases of accidental intoxication from full-spectrum hemp oil are uncommon and dose-dependent.
The table below summarises how THC content and psychoactivity vary across hemp-related products:
| Product | THC content | Psychoactive? |
|---|---|---|
| Hemp seed oil | None (0%) | No |
| Broad-spectrum CBD oil | Undetectable or trace | No |
| Full-spectrum hemp oil | Up to 0.3% | No at typical doses |
| Marijuana-derived oil | High (often 10–30%+) | Yes |
Pro Tip: If you want to be completely certain a product contains no THC, choose a broad-spectrum CBD oil or a cold-pressed hemp seed oil with a third-party lab certificate confirming cannabinoid content.
Can hemp oil cause a positive drug test or impair mental function?
Hemp oil will not impair your mental function. The effects of hemp oil on the body are nutritional and, in the case of CBD-containing products, potentially calming through the endocannabinoid system. Neither hemp seed oil nor broad-spectrum CBD oil causes the cognitive impairment associated with THC.
Drug testing is a separate and more nuanced matter. Research from RTI found that participants who consumed doses of 1.0 mg or more of delta-9 THC returned positive urine drug tests, even without experiencing significant intoxication. This is a critical distinction. Testing positive and feeling high are not the same thing.
Conventional drug tests cannot reliably distinguish between THC from illicit cannabis and trace THC from legal hemp products. The tests detect THC metabolites, not the source. The same RTI research found that positive urine samples appeared up to one week after the last dose, even after a washout period. That means trace THC can linger in the body long after any possible effect has passed.
If you are subject to workplace or legal drug testing, follow these steps:
- Choose hemp seed oil or a broad-spectrum CBD product with a verified zero-THC lab report.
- Read the product label carefully and look for “cannabinoid-free” or “THC-free” wording.
- Check whether the brand publishes third-party Certificates of Analysis (COAs) for every batch.
- Avoid full-spectrum hemp oils if drug testing is a concern, even though they are legal.
- Consult your employer’s testing policy before starting any hemp or CBD product.

What is hemp oil used for? Health benefits without the high
Hemp seed oil is valued for its nutritional profile, not for any psychoactive effect. It is one of the few plant oils that contains omega-3 and omega-6 fatty acids in a naturally balanced ratio. A clinical trial published in Food & Function showed that hemp product consumption modulated plasma fatty acid profiles without any negative cardiometabolic effects. That is a meaningful result for anyone interested in heart health and nutrition.
The most common uses of hemp seed oil include:
- Nutrition: Added to smoothies, salad dressings, and health foods for its fatty acid content
- Skincare: Applied topically to moisturise and soothe dry or irritated skin
- Hair care: Used as a conditioning treatment to improve shine and manageability
- Supplement capsules: Taken daily as a nutritional supplement alongside other vitamins
- Cooking: Used as a finishing oil (not for high-heat cooking, as heat degrades the fatty acids)
Cold-pressed hemp seed oil retains its vitamins and fatty acids through gentle extraction, which is why it is popular in both personal care and nutrition. The absence of cannabinoids makes it suitable for daily use without any concern about psychoactive effects or drug test implications.
How to choose hemp oil safely without risk of intoxication
Choosing the right hemp oil product protects you from both unwanted effects and potential drug test complications. The market contains a wide range of products labelled as hemp oil, and not all of them are the same.
Follow this checklist when selecting a hemp oil product:
- Check the label: Look for “hemp seed oil” or “cold-pressed hemp seed oil” if you want a cannabinoid-free product.
- Request a COA: Reputable brands publish third-party Certificates of Analysis confirming cannabinoid levels.
- Avoid vague labelling: Products labelled only as “hemp oil” or “hemp extract” may contain CBD or trace THC.
- Choose broad-spectrum for CBD benefits: If you want CBD’s potential wellness effects without THC, broad-spectrum is the right choice.
- Avoid full-spectrum if drug-tested: Full-spectrum products contain up to 0.3% THC, which can trigger a positive result.
- Buy from regulated UK brands: UK regulations require CBD products to meet strict standards. Stick to brands that comply with Food Standards Agency (FSA) guidelines.

Hemp oil myths I keep seeing, and why they matter
People ask me whether hemp oil will get them high more often than almost any other question about cannabis-derived products. The confusion is understandable. The marketing around hemp, CBD, and cannabis has moved faster than public understanding, and the terminology is genuinely inconsistent across brands and retailers.
What I find most striking is how rarely people distinguish between hemp seed oil and hemp-derived CBD oil. These are fundamentally different products with different compositions and different purposes. Hemp seed oil belongs in your kitchen or your skincare routine. CBD oil belongs in a wellness conversation that includes a proper look at the product’s cannabinoid profile and your personal circumstances.
The drug testing issue is the one that concerns me most for readers. Feeling no high and testing negative are not guaranteed to go together. The RTI research on this is clear: trace THC can persist in the body and trigger a positive result even when there is no impairment whatsoever. If your job, sport, or legal situation involves drug testing, you need to treat hemp and CBD product selection as a serious decision, not an afterthought.
My honest advice is this: read the COA, not just the label. A product can legally call itself hemp oil while containing meaningful amounts of CBD or trace THC. The COA tells you exactly what is in the bottle. Any brand worth buying from will publish it without hesitation.
