What is CB9? A new cannabinoid?

What is CB9? A new cannabinoid?

Over recent times, new cannabinoids have burst onto the hemp market in Europe. Especially since HHC and other synthetic cannabinoids were banned in many countries, we have seen the appearance of other new cannabinoids that have some psychoactivity and are not illegal. One of them is CB9, a supposed new cannabinoid with psychoactive properties that the internet is full of information about. What is the cannabinoid CB9? Researcher Masha Burelo tells us what she has found out about CB9.

What is CB9?

CB9 is supposedly a new cannabinoid that has certain psychoactive properties. If we search the internet, 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 vaporizer products to CBD flower and CBD hash with this cannabinoid added to give them a psychoactive effect.

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

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

Effects of CB9

If you came here looking for information on the effects of CB9, I'll summarise what is commonly found on blogs and online forums, because, as I mentioned, no such compound is 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 said that CB9 provides a feeling of relaxation and euphoria, although less intense 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 doses have not been established because it has only recently appeared 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.
  • Drug tests: It is suggested that CB9 may go undetected in conventional drug tests, as these usually focus on THC metabolites.
  • Uncertain legal status: Its legal status is unclear in many countries because it is so new.
  • Interaction with CB1 receptors: Some say that CB9, like THC, interacts with CB1 receptors in the brain.

Reality or marketing strategy?

When researching CB9, you can't help asking: where does this information really come from? Who first identified and classified CB9? Why was it given the name CB9, without a detailed description of its structure or function?

Scientific mentions of CB9

In the scientific literature, there is a single mention of CB9, not as a cannabinoid but in relation to “putative cannabinoid receptors”. A book on cannabinoids mentions the CB9 receptor, which appears to work 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 the scientific methodology behind the claims are not clearly stated. In my view, without scientific publications detailing the chemical structure of CB9 and how it was discovered or synthesised, it is hard to consider it a genuine cannabinoid. It could even be a synthetic compound, promoted as natural to make it more appealing in the cannabis market. This is just my hypothesis, but in a context where misinformation can be common, I prefer to rely on reliable sources and formal studies.

Conclusion

The emerging market for synthetic cannabinoids operates largely without specific regulation, which makes it easy for products without quality and safety controls to appear on the market. Examples of this are the ban on synthetic cannabinoids in France, the ban on HHC in Germany, and other countries that have joined in restricting the sale of these products.

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

At Cannactiva you will only find high-quality CBD flower and CBD hash, without CB9 or other synthetic cannabinoids:
