Euphoria 97% H4CBD Cartridge 1ml (510 Thread)

What H4CBD is, and what is in this cartridge

H4CBD is hydrogenated cannabidiol. Chemists take CBD, a compound the hemp plant does make, and add four hydrogen atoms to it in a laboratory. What comes out is a different molecule that the plant does not produce. That is what semi-synthetic means: a plant-derived starting material, chemically altered into something else.

This matters for the obvious reason. If you are buying it because you want CBD, you are not buying CBD, and none of what is known about CBD transfers automatically to it. We have written the longer version of this in our guide to what H4CBD is, and it is worth reading before you order anything in this aisle.

As for the hardware, this is a straightforward 1ml cartridge on a universal 510 thread, which is the standard fitting used by most vape pen batteries. The filling is quoted across the trade at 97 per cent, which works out at roughly 940mg in the cartridge. We quote that as the trade figure rather than as ours, because our own catalogue record carries no strength for this line and the manufacturer's product page is currently unreachable.

One honest note before you go further: this cartridge and all four of its flavours currently read as out of stock, at our distributor and across most of the shops listing it. We would rather tell you at the top than at the basket.

The contradiction at the heart of how H4CBD is sold

This is the part worth reading properly, because once you see it you cannot unsee it.

The argument that H4CBD is lawful in the UK rests almost entirely on one claim: that it is not psychoactive. The Psychoactive Substances Act 2016 catches substances capable of producing a psychoactive effect, meaning something that affects mental functioning or emotional state. Several wholesalers therefore argue H4CBD sits outside the Act because it does no such thing.

Now look at how the same substance is marketed. One UK retailer's headline calls it the high strength cannabinoid taking the UK by storm. The retailer with the longest page about this exact cartridge describes it as offering a more noticeable experience. A UK cannabis publication reporting on it describes reportedly mild intoxicating effects, with consumer accounts ranging from something comparable to a balanced CBD and THC product up to a considerably more significant effect. The same piece quotes an expert saying that the synthesised nature and psychoactive properties would point towards the Psychoactive Substances Act.

Both cannot be true. A substance cannot be outside the Act because it produces no psychoactive effect while being sold on the strength of the effect it produces. That tension is not a technicality, it is the whole regulatory question, and the Advisory Council on the Misuse of Drugs is currently reviewing H4CBD among other ingredients.

We are not going to tell you H4CBD is illegal, because that has not been determined. We are also not going to tell you it is fine, because the argument that it is fine contradicts the marketing sitting next to it. What we will say is that this line is stocked as a deliberate decision, that the position may change, and that you should buy it knowing that rather than reassured by a sentence about THC.

Being THC free does not answer the question

Every page we examined leads on the absence of THC. One states that being completely THC free guarantees the product's legality in most countries. Another runs headings reading UK CBD Compliance, UK THC Compliance and CBD Content, on a cartridge that is not CBD, and rests its compliance case on THC testing.

Testing for THC on an H4CBD product answers a question nobody was asking. THC content is what matters for a hemp extract, because THC is the controlled cannabinoid that a plant-derived product might carry across the line. For a molecule that was manufactured in a laboratory and does not occur in the plant, the risk sits somewhere else entirely: in whether the substance itself is caught by legislation aimed at synthesised compounds.

For completeness, since it comes up on every page in this aisle: the UK consumer test for controlled cannabinoids is a quantity, no more than 1mg of THC, THCV and CBN in the container, whatever size the container is. The percentage figures quoted around the CBD trade come from Home Office rules on what a licensed grower's standing crop may contain in a field. Neither of those tests is the one that decides anything about H4CBD.

Where the hundred times stronger claim actually comes from

You will see it everywhere: H4CBD is a hundred times stronger than CBD. It is worth knowing where that number originates, because it is not what most people take it to mean.

It comes from binding affinity at the CB1 receptor, measured in a laboratory. H4CBD binds to CB1 far more readily than CBD does. But CBD's own affinity for CB1 is very low to begin with, and a hundredfold multiple of a very small number is still a small number. Binding affinity is also not the same thing as an effect you would notice.

The one analysis in the ranking set that engages with this at all suggests the practical difference is nearer threefold than hundredfold. The cannabis publication covering it is franker still, saying plainly that it is difficult to be sure what the figure really means, and that considerably more research is needed on the effects and, more importantly, the safety of what is still a new compound.

Nobody selling this cartridge explains any of that. If a hundredfold figure is what drew you to H4CBD, it is worth knowing it describes a receptor measurement rather than a promise about how anything will feel.

Why Novel Foods bites the gummies and not this cartridge

This distinction gets flattened everywhere and it is worth being precise about, because it changes which of our own products you should be cautious about and why.

The Novel Foods regime governs things you eat and drink. Ingestible CBD requires Food Standards Agency authorisation, with validated products appearing on a public list. H4CBD holds no such authorisation, and the reporting on it is unambiguous that ingestible H4CBD products are unlawful in the UK and the EU under Novel Foods.

A vape cartridge is not eaten. CBD vapes and topicals sit outside the Novel Foods regime entirely, and so does an H4CBD one. So on this page, Novel Foods is not the live issue. The Psychoactive Substances Act question set out above is.

Where it does bite is on the H4CBD products in our range that you swallow: the gummies, the oils and the distillate shot. Those are foods, they contain a cannabinoid with no authorisation, and we are not going to pretend otherwise on their pages either. If you have been browsing the H4CBD range generally, that is the line to keep in mind: inhaled and ingested are different regulatory questions, and only one of them is about Novel Foods.

The four flavours

Four terpene profiles, and one thing to understand before you choose. These are strain names describing a terpene blend the cartridge is built to imitate. They are not extracts of those strains, and the H4CBD itself was made in a laboratory rather than pressed out of any particular plant. The name tells you what it smells and tastes like, nothing more.

Only one page anywhere describes any of them, and it covers a single flavour. The descriptions below are of the terpene profiles those strain names conventionally refer to.

If you wanted a CBD cartridge, buy a CBD cartridge

Plenty of people arrive at an H4CBD listing because it appeared in a CBD search, which is exactly how ours is currently shelved and something we should be straight about. If cannabidiol is what you were after, the alternatives below are actual CBD, on the same 510 fitting, and none of them raises the questions set out above.

The comparison worth making is not strength but what the cannabinoid actually is, so that is the column to read first.

Who should not buy this

If you want CBD, do not buy this. It is a different molecule, and the two are not interchangeable however similar the names look on a shelf.

If you are new to cannabinoids, this is a poor place to start. It is a high-concentration cartridge of a compound with far less research behind it than CBD, and the honest summary of the evidence is that more work is needed on both its effects and its safety.

If you are subject to workplace drug testing, or you drive for a living, or you are in any setting where an unexpected effect would be a serious problem, avoid it. The accounts of what H4CBD does vary widely, which is precisely the reason not to find out in those circumstances.

If you need regulatory certainty, this is not the product for you, and we would rather lose the order than dress up a contested position as a settled one. Our CBD vape and cartridge range is on much firmer ground.

And it is out of stock in every flavour at the moment, so for now the question is academic.

18+ only, as with everything we sell.
