Professor Herb Red Lebanon H4CBD Solid Extract 2.0g

What H4CBD is, plainly

H4CBD is made by taking CBD and adding hydrogen to the molecule, a process called hydrogenation. The result is a related but different compound that does not occur in the plant in any meaningful quantity. That is what semi-synthetic means: it starts from something natural and is altered in a laboratory into something that is not.

It is not CBD, and the two should not be treated as interchangeable however similar the names look. No H4CBD product holds authorisation under the Novel Foods regime, and nothing on this page should be read as suggesting that it does or that it has been assessed by anyone.

Because this product is intended to be smoked or vaporised rather than eaten, the live regulatory question is not Novel Foods but the Psychoactive Substances Act 2016, which our page on the brand's wider H4CBD solid extract range covers in more detail. Our learn article on H4CBD sets out the full picture and is the better starting point if this is new to you.

We stock this range on an explicit owner decision, taken with the above set out in front of them. We are not going to soften it here.

One small badge separates this from the CBD pack

We stock both of this brand's Red Lebanon products, so we have been able to put the two cards side by side. They are very nearly the same design.

Both carry a red ribbon reading RED LEBANON. Both have the same SOLID EXTRACT banner above it, the same 2.0g weight flash in the top corner, the same brand seal, and the same tagline printed underneath the ribbon in the same typeface.

The difference is one lime badge in the lower left. On the CBD product that badge reads EXTRA HIGH STRENGTH. On this one it reads H4CBD. Same colour, same shape, same position on the card.

So the only thing on the front of the pack marking this out as a semi-synthetic cannabinoid rather than a hemp extract sits exactly where the other product prints a marketing flash. We are not suggesting that was done to confuse anybody, and style-consistent packaging across a range is completely normal design practice. But if you are choosing between the two on a shelf or in a photograph, the lime badge in the bottom-left corner is the thing to read, and it is the only thing that will tell you.

What Red Lebanon can and cannot mean on this pack

Red Lebanon is not a vague word. It names a specific tradition, and we set out what that tradition involves on our CBD Red Lebanon page: a later harvest, plants dried in the sun, resin sifted from the dried flower through fine mesh or silk screens, the powder wrapped in cloth and pressed with gentle heat, and then the bricks aged for something in the region of four to eight months so the resin slowly oxidises and darkens.

Every part of that describes time and the handling of plant resin. The colour the name refers to is the visible result of months of ageing.

H4CBD has not been through any of it. It is a compound assembled in a laboratory from CBD, so there is no harvest date, no drying, no sifting and no ageing period for anything to darken during.

Which means the name here cannot be describing how the material was produced. What it can describe is the result: a colour and an aroma built to resemble the traditional article. That is a legitimate thing for a style name to do and the whole category does it, from Moroccan to Bubble. It is worth knowing all the same, because anyone who recognises Red Lebanese as a production tradition will read the name as a claim about process, and on this pack it is not one.

Four products, two names, two different substances

The naming overlap runs further than one pair. Professor Herb uses the same style names across both of its 2g solid extract ranges, so our hemp and hash shelf now carries two products called Red Lebanon and two called Moroccan, split across CBD and H4CBD.

The CBD versions publish a stated percentage. The H4CBD versions publish no figure at all, which our page on the wider H4CBD solid extract range goes into.

If you are ordering by name alone, that is the trap. The style name tells you nothing about which of the two substances is in the pot, and on our own site the surest check is which range a product sits in rather than what the ribbon says.

What is in the pot, and what the label does not say

A 2.0g terpene-infused solid extract, dark purple-brown in the brand's photograph, in the same clear pot and hanging card format as the rest of the brand's solid extracts.

What is not published anywhere is a strength figure. The CBD range states a percentage on every one of its five grades. This range states nothing, so there is no published number telling you how much H4CBD is in the pot, and we are not going to estimate one.

The pack carries a QR code to an analysis, as the CBD range does. Who performs that testing and what a cannabinoid panel covers is set out on our Guava Dog page, though a panel built around CBD profiling is not necessarily the right instrument for a semi-synthetic compound, and we would not assume it answers the same questions.

We give no guidance on how much of this to use and no description of what it does. That is deliberate.

Who should not buy this

If you want CBD, this is not it, and the similarity of the packaging to the CBD version is exactly why we have written this page the way we have. The hemp solid extract range is what you are looking for.

If you want a product with a published cannabinoid figure, this range does not have one.

If regulatory position matters to you, H4CBD holds no Novel Foods authorisation, and the Psychoactive Substances Act question described above is a real one rather than a technicality. Read our learn article before deciding.

If you assumed the Red Lebanon name meant traditional production, it cannot mean that here.

Over-18s only. This is not a food, it is not a medicine, and nothing on this page describes an effect or recommends an amount.
