Hemp oil is two products, and a state agency says so
The Vermont Agency of Agriculture, Food and Markets publishes a page called “Hemp Seed Oil and CBD Concentrate: Understanding the Difference”. It ranks on the first page of Google for this search.
State agriculture departments do not write consumer explainers for fun. They write them when enough people are being confused, at enough cost, that intervening becomes part of the job.
That is the situation in one sentence. Hemp oil names two products that share a plant and almost nothing else:
- Hemp seed oil is pressed from the seeds. It contains essentially no cannabinoids. It is a culinary and cosmetic oil with an unusually good fatty acid profile, and it is sold by the gallon.
- CBD oil comes from the flowers and leaves. It contains cannabidiol, and it costs an order of magnitude more per millilitre.
Both are correctly called hemp oil. Neither seller is lying. And that is precisely why the confusion has survived a decade of complaints and a state regulator’s intervention.
The two products, side by side
What each one is
| Hemp seed oil | CBD oil | |
|---|---|---|
| Part of the plant | seeds | flowers and leaves |
| Cannabinoids | essentially none | the entire point |
| Typical use | food, skincare | ingested for cannabinoids |
| Where you find it | supermarket, Amazon, by the gallon | specialist shops |
| Price per millilitre | that of a culinary oil | not comparable |
Why the seeds contain nothing
Cannabinoids are produced in the trichomes — the resin glands that cover the flowers and, to a lesser extent, the leaves. The seed is not where the plant makes them.
Trace amounts can appear on seed hulls through contact during harvest, which is why hemp seed oil occasionally shows a barely detectable reading. It is contamination, not content.
Why both names are correct
“Hemp seed oil” accurately describes an oil pressed from hemp seeds. “Hemp” accurately describes the plant cannabidiol comes from. Both usages are true, which is exactly what makes the ambiguity impossible to regulate away.
You cannot ban a company from calling its hemp seed oil hemp oil, because that is what it is.
The scale of the price gap
A litre of hemp seed oil is priced like a good culinary oil. Ten millilitres of a strong CBD oil can cost more than that litre. The two sit in completely different economies, which is what makes the confusion worth exploiting.
Why this SERP proves the point
Half the results are about food and skin
The search results for “hemp oil” include an Amazon listing for extra-virgin unrefined seed oil, a one-gallon jug of USDA-organic seed oil, a page about hemp oil for skin, and several nutrition pieces about fatty acids.
Nobody looking for cannabidiol wants a gallon of anything. The results are answering a different question, correctly, because the words are genuinely ambiguous.
And a state regulator sits in the middle of them
Vermont’s page is short — around five hundred words — and it ranks anyway. That is what happens when a page answers the actual question with no commercial interest attached.
What that tells a buyer
If a term is ambiguous enough that an agriculture department publishes a disambiguation, you should assume that any product using it might be either. The name is not a specification.
The check that settles it in ten seconds
Look for a milligram figure
A cannabidiol product states a quantity — a percentage, or a total in milligrams, or both. It has to, because that number is what you are paying for.
Hemp seed oil states no cannabinoid quantity, because it has none to state.
If no milligram figure appears anywhere on the label or listing, it is not a CBD product. That single test resolves almost every case.
Look at the named ingredient
A cannabidiol product names an extract: hemp extract, Cannabis sativa L. extract, cannabidiol, full spectrum hemp extract. A seed oil names Cannabis sativa seed oil — which, incidentally, is its INCI name in cosmetics.
That word seed is the whole distinction, and it is usually right there.
Look at the volume and the price
A 500 ml or 1 litre bottle at a supermarket price is seed oil. Nobody sells a litre of CBD oil, because it would cost more than a car service.
Where the trick lives
Marketplace listings. Platform rules frequently remove listings that mention cannabidiol, while allowing “hemp oil”. The predictable outcome is bottles priced like CBD whose ingredients list only seed oil, and whose imagery leans heavily on green leaves.
The seller has broken no rule. The buyer receives a perfectly edible product containing none of what they were looking for.
Hemp seed oil is genuinely good at something
The point of this page is not that seed oil is inferior. It is a good product being mistaken for a different one, and it deserves its own paragraph.
The fatty acid profile
Hemp seed oil is notable for containing omega-6 and omega-3 fatty acids in a ratio close to 3:1, which is unusual among culinary oils and closer to what nutrition research generally regards as favourable than most of what is on a supermarket shelf.
It also contains gamma-linolenic acid, which few common oils do.
In the kitchen
It has a nutty, grassy flavour and a low smoke point, which makes it a finishing oil rather than a frying oil. Use it on salads, on cooked vegetables, in dressings. Heating it hard wastes both the flavour and the fatty acids.
On skin
Hemp seed oil is a light, non-comedogenic oil widely used in cosmetics, where it appears on ingredient lists as Cannabis sativa seed oil. That is a legitimate cosmetic use with a long history, entirely independent of cannabinoids.
How to store it
Polyunsaturated oils oxidise. Keep it cool, dark and closed, buy quantities you will finish, and expect a shorter shelf life than olive oil. A rancid hemp seed oil smells like old paint and should be thrown out.
One plant, three separate crops
The price gap is not a markup. It comes from the fact that hemp is grown three different ways for three different industries, and the farming barely overlaps.
Fibre
Grown densely, harvested tall, processed for stalk. It goes into textiles, rope, paper, insulation and hempcrete. Density is the point: crowded plants grow straight and put their energy into stem.
Grain
Grown for seed, which is pressed for oil or sold as hulled hearts. This is a commodity crop, harvested with adapted combine equipment, priced per tonne like any other oilseed.
Hemp seed oil is a by-product of an agricultural commodity, which is why it costs what a culinary oil costs.
Cannabinoids
Grown spaced far apart, kept unpollinated, often started from clones rather than seed, harvested by hand, dried carefully, then extracted and refined.
Unpollinated matters: a fertilised female plant redirects resources into producing seed and the resin yield falls. So a cannabinoid crop and a grain crop are not merely different varieties — they are mutually exclusive on the same field, because pollen travels.
Why that settles the price question
Grain hemp is a machine crop measured in tonnes. Cannabinoid hemp is a horticultural crop measured in grams of extract, requiring separation from any grain field within pollen range.
A litre of seed oil and ten millilitres of CBD oil come from two different agricultures. The hundredfold price difference is not a scam — it is the honest cost of two very different jobs.
And why the varieties differ too
Grain and fibre varieties are bred for yield of seed or stalk and are naturally low in cannabinoids. Cannabinoid varieties are bred for resin. A field of one is not a usable source of the other, which is another reason the two products never converge.
Hemp cleans soil, and that is your problem
Here is the fact that changes how you read a certificate, and it applies to both products on this page.
The plant is a bioaccumulator
Hemp draws heavy metals and other contaminants out of soil and holds them in its tissue. This is a documented property, and it is useful — hemp has been trialled as a phytoremediation crop, including in soil contamination projects, precisely because it is good at extracting what you do not want in the ground.
Why a virtue becomes a liability
A plant that concentrates cadmium, lead and nickel from the soil is excellent for cleaning a field and a poor choice for an unmonitored food chain. Whatever was in the ground has a route into the crop, and from the crop into an oil.
It applies to seed oil too
This is the part people miss. The heavy-metal question is not exclusive to cannabinoid extracts — grain hemp is grown on soil like any other crop, and the plant’s accumulation habit does not switch off because the buyer wanted salad dressing.
Reputable producers test. The check is the same for both products: a laboratory panel covering heavy metals, pesticides and, for extracts, residual solvents.
What that means when comparing certificates
For most botanicals, the contaminant panel is a formality. For hemp it is the part of the document that is genuinely doing work, and a certificate that reports cannabinoids but omits heavy metals has skipped the more informative half.
And where the soil was
Country of cultivation is worth a glance for the same reason. It is not a guarantee of anything, but a producer who names the region and shows a contaminant panel is telling you they know why the question exists.
Reading a cosmetic label
The INCI system
Cosmetics in Europe list ingredients using INCI names, which are standardised across the industry. This is where the two products become easiest to tell apart, because the names are unambiguous:
- Cannabis sativa seed oil — seed oil, no cannabinoids
- Cannabidiol — the actual compound
- Cannabis sativa leaf extract or flower extract — from the parts that contain cannabinoids
What a cream that says “hemp” contains
Very often the first of those three. A product marketed on cannabinoid imagery whose INCI list shows only Cannabis sativa seed oil is a seed oil cream, whatever the packaging suggests.
Why this matters more in cosmetics
Because a cream cannot be tasted or measured by the user, and because cannabinoid claims sell at a premium. The INCI list is the only place the truth is required to appear, and it is required to appear in full.
If you actually wanted CBD
What the label should tell you
A quantity in milligrams or a percentage, an extract named as such, and a batch certificate. The conversions:
percentage × 10 = mg/ml. A 10 % oil is 100 mg/ml. total mg ÷ millilitres = mg/ml. A 30 ml bottle at 1,500 mg is 50 mg/ml — half the strength of a 10 ml bottle at 1,000 mg. price ÷ total mg = cost per milligram, which is the only honest comparison.
The certificate
A batch certificate of analysis from an independent laboratory, with a code matching the bottle. A 2024 review in The Journal of Pain found products sold in North America and Europe with cannabidiol content ranging from none to much more than advertised — which makes the certificate the only defence available.
And what nobody may claim
There is not a single authorised health claim for cannabidiol in the EU register, for any purpose. EFSA’s provisional safe intake for cannabidiol as a food, published 9 February 2026, is about 2 mg a day for a 70 kg adult, and excludes anyone under 25, pregnant, breastfeeding or taking medication.
Hemp seed oil, by contrast, is simply a food. It carries none of that regulatory weight, because it contains none of the compound that attracts it.
The third thing sometimes called hemp oil
Rick Simpson oil and similar preparations
A concentrated cannabis extract, high in THC, is occasionally marketed under the hemp oil name online. It is not hemp by any legal definition, and it is a controlled substance in most places.
How to recognise it
Extremely high advertised concentrations, dark thick consistency described as a paste rather than an oil, syringes rather than dropper bottles, and health claims of the kind no legitimate seller would put in writing.
Why it matters here
Because the ambiguity of the phrase provides cover. Someone searching innocently for a nutritional oil can land on something that is neither food nor supplement, and the shared name is the reason.
The other hemp words, and what each guarantees
Once the seed-versus-flower question is settled, a second layer of vocabulary starts. None of it is dishonest and none of it is precise.
“Hemp extract”
Usually means a cannabinoid-containing extract, but the phrase itself does not specify a quantity. An extract can be rich or nearly empty, and only a milligram figure distinguishes them.
“Hemp derived”
Says where the starting material came from, not what the finished compound is. Delta-8 THC is hemp-derived and intoxicating; cannabidiol is hemp-derived and is not.
On a label, this phrase answers a question about agriculture while appearing to answer one about pharmacology.
“Aerial parts”
A genuinely informative term, and a good sign. It means the above-ground parts of the plant — flowers, leaves, stems — which is where cannabinoids live. A producer writing this is being specific on purpose.
“Full spectrum hemp” and “hemp complex”
Neither has a legal definition. “Full spectrum” conventionally implies the plant’s cannabinoid profile including trace THC; “hemp complex” and similar coinages imply nothing at all and exist because they sound like something.
The certificate is where these words acquire meaning, or fail to.
“Broad spectrum, 0 % THC”
Almost always means below the testing laboratory’s limit of detection rather than genuinely zero, and detection limits differ between laboratories. For anyone screened at work, that gap is the whole question.
The rule underneath all of them
Every one of these phrases is chosen to survive legal review while implying more than it states. Read them as legal artefacts and they become informative in a different way — not about what the product does, but about what its maker knows they cannot put in writing.
The short version
The distinction
Hemp seed oil comes from seeds and contains essentially no cannabinoids. CBD oil comes from flowers and leaves and contains cannabidiol. Both are legitimately called hemp oil, and one costs many times the other.
The ten-second test
Look for a milligram figure. If there is no cannabinoid quantity anywhere on the label, it is not a CBD product. Then look for the word seed in the ingredients, which settles the rest.
Neither one is worse
Hemp seed oil is a good culinary and cosmetic oil with a favourable fatty acid profile and a genuine use. It is simply not what someone searching for cannabidiol is trying to buy.
And the tell that a market has a problem
When a state agriculture department publishes a page explaining a product name, the ambiguity has already cost enough people enough money to become a regulator’s business.
