What is CB9: A New Cannabinoid?

Masha Burelo, PhD•November 18, 2024

Last updated: June 12, 2026

What is CB9: A New Cannabinoid?

In recent times, new cannabinoids have burst onto the hemp market in Europe. Especially after the prohibition of HHC and other synthetic cannabinoids in many countries, it has been possible to observe the appearance of other new cannabinoids that have some psychoactivity and are not illegal. This is the case of CB9, a supposed new cannabinoid with psychoactive properties about which the web is full of information. What is the cannabinoid CB9? Researcher Masha Burelo tells us about her findings on CB9.

What is CB9?

CB9 is supposedly a new cannabinoid that has certain psychoactive properties. If we do an internet search, we see that CB9 is presented as a natural cannabinoid that comes from the cannabis plant. There are several products with CB9 on the market, from cartridges and vaporization products, to CBD flowers and resins to which this cannabinoid is added to have a psychoactive effect.

However, a more exhaustive search shows that there is no scientific evidence of the chemical structure of CB9 or its origin. This is rare, and it should be noted that there is scientific literature on other new cannabinoids and their chemical formula, such as HHC, HCCPO or H4CBD.

Most of the data on CB9 comes from cannabis blogs and websites, and in many cases the articles simply repeat the same details without citing research or studies. Some sources claim that CB9 is a cannabinoid derived from cannabidiol (CBD), while others claim it is a precursor to cannabidiol (CBD). To date, no book, scholarly article, major university website, or reputable scientific publication has mentioned CB9 as an established cannabinoid in research.

Effects of CB9

If you came here looking for information on the effects of CB9, I will summarize what is commonly found in blogs and online forums, because as I mentioned, there is no such compound described in the scientific literature.

In the realm of alleged user testimonials and observations, a mild psychoactive effect is reported, which fuels the theory that it may interact with CB1 receptors in the brain. However, I reiterate that this lacks scientific evidence.

Among the claims circulating about CB9, the following stand out:

  • Effects similar to CBD, but with mild psychoactivity: Although it is said to have a similar structure to CBD, mild psychoactive effects are reported.
  • Relaxation and euphoric effect: It is mentioned that CB9 provides a feeling of relaxation and euphoria, although with less intensity than THC.
  • Potential therapeutic effects: It is speculated that CB9 may offer benefits such as pain relief, anti-inflammatory properties, mood regulation and improved sleep quality.
  • Dosage and side effects: Optimal dosages have not been established due to its recent appearance on the market, and typical side effects may include dizziness and dry mouth.
  • Possible sensory effects: Given its psychoactive nature, some users report slight alterations in sensory perception.
  • Doping tests: It is suggested that CB9 may go undetected in conventional doping tests, as these usually focus on THC metabolites.
  • Uncertain legal status: Its legal status is unclear in many countries due to its novelty.
  • Interaction with CB1 receptors: Some say that CB9, like THC, interacts with CB1 receptors in the brain.

Reality or marketing strategy?

When researching CB9, it is inevitable to ask: where does this information actually come from? Who first identified and classified CB9? Why was it given the name CB9, without a detailed description of its structure or functionality?

CB9 scientific mentions

In the scientific literature, there is a single mention of CB9, but not as a cannabinoid, but in relation to "putative cannabinoid receptors." In a book on cannabinoids, there is mention of the CB9 receptor, which appears to function as an allosteric site on serotonin (5-HT3) receptors, although this concept has not been thoroughly investigated or confirmed (1).

I must admit that I tend to be wary of online publications, especially when the sources or scientific methodology behind the claims are not clearly stated. In my view, without scientific publications detailing the chemical structure of CB9 and its discovery or synthesis process, it is difficult to consider it to be a genuine cannabinoid. It could even be a synthetic compound, promoted as natural to increase its attractiveness in the cannabis market. This is just my hypothesis, but in a context where misinformation can be frequent, I prefer to rely on reliable sources and formal studies.

Conclusion

The emerging market for synthetic cannabinoids operates largely without specific regulation, making it easy for products without quality and safety controls to appear on the market. Examples include the ban on synthetic cannabinoids in France, the ban on HHC in Germany, and more countries that have joined in restricting the marketing of these products.

CB9, as described on some websites, is available in a variety of cannabis products, but until reliable academic research and publications are available, this compound will remain an unknown. For now, I recommend caution and skepticism, and perhaps, in the future, science will provide more clarity on the true nature of CB9.

In Cannactiva you will only find high quality CBD flowers and cannabis resins, without CB9 or other synthetic cannabinoids:
