What is CB9 and how is it different from CBD and HHC? Discover the effects and range of CB9 products

What is CB9? Formation and chemical structure

CB9 is another cannabinoid discovered in the cannabis plant. Scientists have already identified more than 150 cannabinoids. CB9 is derived from CBD (cannabidiol). At the moment, they are still investigating exactly how it is produced. All we know is that it is a complex chemical process in cannabis, with other cannabinoids (CBD and THC) serving as starting substances. 

The cannabinoid CB9 has a natural 5-carbon chain and differs slightly in chemical structure from CBD. But because even a slight change in structure causes the effects of the cannabinoids to be different, CB9, unlike CBD, is psychoactive.

Unique features of CB9

The essential difference that distinguishes it from other cannabinoids is that it is not prone to crystallization. This aspect is likely to affect its composition in products, solubility, stability and also use.

Although CB9 has a similar structure to the cannabinoids CBD and H4CBD, it dominates in its psychoactive effects. Because of the variation in structure, CB9 is difficult to detect by standard testing methods such as HPLC (high performance liquid chromatography).

What are the effects of CB9?

Much of the effects of cannabinoids have been found to be related to how they interact with the endocannabinoid system (ECS) in our bodies. The ECS affects various bodily functions, including sleep, pain, mood, movement and immunity. This complex system is made up of endocannabinoid receptors (CB1 and CB2 being the most well-known), endocannabinoids and enzymes.  

CB1 receptors are found primarily in the brain and nervous system, while CB2 receptors are found in the immune system, digestive tract and other organs.

If we liken the effects of CB9 to other cannabinoids, they seem to resemble HHC and delta-8-THC. HHC (hexahydrocannabinol) produced in the laboratory is a mixture of 2 stereoisomers, with the active molecule (9R)-HHC probably binding very efficiently to the CB1 receptor and weakly to the CB2 receptor, hence producing a psychoactive effect.

It can be assumed that CB9 will trigger:

  • feeling of euphoria
  • relaxation
  • slightly altered sensory perception

 The interaction of CB9 with ECS is under investigation. It is currently unknown how CB9 interacts with this system.

Potential benefits of CB9

Although CB9 research is at the starting line, current findings suggest that it could have considerable therapeutic potential.

It is thought that it could exhibit neuroprotective, anti-inflammatory and sedative properties. Its use appears to be particularly useful in:

  • promoting overall well-being (relieving stress and anxiety)
  • improving sleep
  • chronic pain and inflammation
  • neurodegenerative diseases

There is now a growing interest in detailed research to understand exactly what the benefits of the cannabinoid CB9 are.

CB9 vs. CBD vs. HHC comparison table





Chemical formula




Occurrence in the cannabis plant



Yes, but only in trace amounts.

Production process

CBD derivative, produced by a complex chemical reaction in the plant; the cannabinoids CBD and THC act as starting substances.

It is obtained using one of the extraction methods, which include:

  • carbon dioxide (CO2) method
  • using solvents
  • from vegetable oils

It is produced by a hydrogenation process mainly from CBD, possibly from terpenes such as citronellal or olivetol.

Psychoactive properties





  • euphoria
  • relaxation
  • slightly altered sensory perception

It is not psychoactive.


It shows therapeutic potential to:


  • euphoria
  • increased energy
  • change in perception
  • relaxing effects


Cooperation with ECS

Probably specificcooperation with the ECS, resulting in uniqueeffects.

How CB9 interacts with the ECS has not yet been elucidated by scientists.

Low binding to CB1 and CB2, it acts as a modulator of these receptors. It also affects adenosine, serotonin and vanilloid receptors.

Molecule (9R)-HHC: seems to bind very efficiently to the CB1 receptor.


  • CB9 distillate
  • CB9 flowers and hash
  • CB9 vapes
  • CB9 gummies

The most widely used cannabinoid on the market.


  • HHC oils and drops
  • flowers
  • HHC vapes a cartridge
  • HHC liquids
  • HHC distillates
  • concentrates and extracts
  • edibles
  • HHC gummies and candies


Availability and offer of CB9 products

On the Czech market, CB9 products are not as easy to find as CBD or HHC, but this is expected to change soon.

On the foreign market you will mainly find CB9 products in the form of vapes, spirits, flowers, hashes and CB9 gummies.


The cannabinoid CB9 is another example of how diverse and complex the cannabis family is. Cannabis continues to surprise us and we can look forward to learning more about this herb. So be sure to stay in the cannabis mood so you don't miss out on any more exciting discoveries.
