Monkey King H4CBD Hash Incense, 1.75g

What H4CBD actually is

CBD is a cannabinoid the hemp plant makes on its own. H4CBD is not. It is made by taking CBD and running it through hydrogenation, a chemical process that adds four hydrogen atoms to the molecule, which is where the H4 in the name comes from. The result is a compound that does not occur in the plant in any meaningful quantity and has to be manufactured.

That single change matters more than it sounds. CBD has a low affinity for the CB1 receptor, which is the receptor THC acts on and the reason CBD is not intoxicating. Research on hydrogenated CBD compounds found a high affinity for CB1 in mice, an interaction described as more similar to the one between THC and CB1, though nowhere near the level THC itself reaches.

In other words, the hydrogenation appears to move the molecule some distance from CBD in the direction of THC. Consumer reports on the effects are inconsistent. Some describe something like a strong CBD with mild intoxication and others report a considerably more noticeable psychoactive effect.

We are reporting that rather than promising it, because the honest position is that nobody selling this compound in the UK is in a position to tell you with confidence what it does.

The near-identical product that is not this one

This is the single most useful thing on the page, so it goes near the top.

Monkey King makes two hash incense products with almost the same name. One is a CBD hash incense at 1.7 grams, sold at a stated 20 per cent full spectrum CBD. The other is this one, an H4CBD hash incense at 1.75 grams. They share the same brand, the same format, the same strain names, and their weights differ by five hundredths of a gram.

A buyer searching for Black Afghan or King Hassan will find both, and nothing about the listing titles makes the difference obvious. The cannabinoid is completely different in each. One is a plant-derived compound with a long consumer track record and the other is a laboratory-hydrogenated derivative studied once, twenty years ago.

We stock the H4CBD version, which is what this page describes. If you were looking for the CBD one, this is not it, and you should buy from a listing that names CBD explicitly.

About the words on the label

The trade copy for this product describes it as extreme high strength and, in the same paragraph, as non-intoxicating. It also attributes deeper relaxation to it and frames it as suitable for everyday aromatherapy use.

Those statements do not sit together. A compound cannot be extreme high strength and have no effect at the same time, and the pharmacology summarised above points away from the non-intoxicating description rather than towards it.

We are not repeating any of it. We do not make claims about relaxation or any other effect, because UK advertising and medicines rules do not permit a retailer to, and because on a compound with one study behind it we would be inventing the reassurance.

What we will say is what is verifiable. It is a pressed block weighing 1.75 grams. It contains H4CBD and terpenes. It is sold as a novelty incense product and labelled not for consumption. Everything beyond that is either marketing or guesswork, and you are entitled to know which is which.

The incense framing, and what it means

Products in this corner of the market are routinely sold under a label that says they are not for consumption. This one is sold as incense. Others in the same category are sold as hemp tea, or simply as a novelty or collector item.

Those framings are doing legal work rather than describing customer behaviour, and it is more useful to say so than to pretend otherwise. A pressed cannabinoid block sold as incense is being placed outside the rules that would apply to a food or a medicine, by declaring it is neither.

The practical consequence for you is straightforward. The product is sold and described as incense, and that is how we list it. We are not going to publish instructions for using it any other way, and a page that does is a page to be sceptical of.

It also means the usual reassurances do not apply. There is no Novel Foods listing for it, because Novel Foods governs food and this is not sold as one. There is no FSA public list entry, and there is not going to be.

The four pressings

The four options are pressings named in the traditional hash naming convention, and the difference between them is aroma and appearance rather than content.

Monkey King describes the range as combining the H4CBD material with preserved natural terpenes, which is where the differences between the four come from. All four were available at the time of writing.

Where this sits legally, stated carefully

This deserves precision rather than a reassuring sentence, so here is the position as the available UK coverage sets it out.

H4CBD is not named in the Misuse of Drugs Act and is not a controlled cannabinoid under it. That is the narrow point people usually mean when they call it legal.

Ingestible H4CBD products are a different matter. Specialists quoted in UK cannabis coverage state that ingestible products are unlawful in the UK and the EU under Novel Foods, because no H4CBD product holds authorisation and no application has cleared. Vapeable products are described as a grey area. The same coverage notes that the compound's synthesised nature and reported psychoactive properties raise the question of whether the Psychoactive Substances Act 2016 applies to it.

Separately, you will find UK retailers claiming H4CBD is compliant because it holds under a fifth of a per cent THC. That is not the consumer test for anything. That percentage is a Home Office rule about a growing hemp crop. The actual test for controlled cannabinoids is a limit of one milligram per container, covering THC, THCV and CBN, and it has nothing to say about H4CBD either way, because H4CBD is not on that list.

So: not controlled, not authorised, not settled. We would rather set that out than print the word legal and leave you to find out the rest elsewhere. Our full explainer on the compound is linked below.

The other H4CBD lines we carry

We stock a small number of H4CBD products and they are all subject to everything said above. Listing them together is more useful than pretending each is a separate question.

If you want CBD rather than H4CBD, the Euphoria CBD shatter is the closest concentrate we carry that is unambiguously cannabidiol, and the CBD oil aisle is the mainstream route.

Who should not buy this

If you want CBD, buy CBD. This is not it, and the near-identical CBD version of this exact product exists elsewhere in the market. Nothing about H4CBD makes it a better or stronger CBD, because it is not CBD at all.

If you are subject to drug testing of any kind, avoid it. There is no meaningful body of evidence on how H4CBD behaves in a screening test and no responsible retailer can tell you it is clear.

If you are pregnant, breastfeeding, under 18, or taking prescribed medication, this is not a product to experiment with. The evidence base is one study published in 2006.

And if you want a straight answer about safety, the most substantial UK coverage of this compound concludes that far more research is needed to establish its true effects and, most importantly, its safety, and that until then the use of any product containing it cannot be deemed safe or responsible. We disagree with that conclusion enough to stock the product on our owner's instruction. We do not disagree with it enough to hide it from you.
