Cannabinoid observatory and product analysis
Which new cannabinoids are legal in Spain? Reading the schedules for HHC, H4-CBD and THCP
A reader could easily mistake H4-CBD for a variety of CBD. Spain’s official gazette treats that added number and letter as an important distinction. Working out what can be said about a refill, a cream or a seed takes two questions. Which compound is present? What does the law cover for this product in this country?

| Label | Entry in the Spanish order | Why the wording matters |
|---|---|---|
| HHC and HHC-O | Hexahydrocannabinol and its acetate | The order names both. |
| HHCP and HHCP-O | Hexahydrocannabiphorol and its acetate | The extra P marks a distinct family. |
| THCP | Delta-8-THCP and delta-9-THCP | The order identifies the two isomers separately. |
| H4-CBD | Hydrocannabidiol, also called tetrahydrocannabidiol | This entry identifies the hydrogenated derivative. |
| THCA | Delta-9-THCA | The order specifies this particular acid. |
What changed in Spain on 23 April 2025
Order SND/380/2025 brought these compounds under the controls in Schedule II of Annex 1 to Royal Decree 2829/1977. The operative article also covers stereochemical variants, racemates and salts where they can exist. An overseas listing that still describes HHC or H4-CBD as an unrestricted retail alternative gives a misleading picture if read as advice for Spain.
Why France singles out CBN
On 6 June 2025, France’s Conseil d’État considered a decision listing a class of compounds by chemical structure. The definition expressly excluded cannabinol (CBN). The court dismissed the challenges. That exception answers a question about the scope of the French listing. A specific refill still raises separate questions about its full composition, its product category and the market where it would be sold.
Where so many new names come from
The EU Drugs Agency’s 2026 report counted 27 cannabinoids notified for the first time to Europe’s early warning system during 2025. Sixteen were semi-synthetic. The date records the network’s first notification. A laboratory can identify a substance and issue an alert well before reliable information about its effects in people becomes available.
What would establish the status of a particular vape?
A checkable answer identifies the compound, matches the laboratory analysis with the batch and provides the rule applicable to the finished product in the destination country. The Spanish order settles several questions about scheduled substances. In the sources reviewed, we found no authorisation supporting a recommendation of these emerging cannabinoid vapes to the Spanish public.
