C1, C2, C3, C4, C5

C1, C2, C3, C4 and C5 are a group of chemical compounds that are classed as derivatives of the cannabis cannabinoid cannabinol (CBN).

As well as containing over 100 different cannabinoids, the cannabis plant also contains a group of cannabinoids that are derived from CBN. This includes Cannabinol-C1, Cannabinol-C2, Cannabinol-C3, Cannabinol-C4 and Cannabinol-C5, which are all also controlled in the UK under the 1971 Misuse of Drugs Act. 

 

What are cannabinoids?

  

Cannabinoids come in two distinct forms: plant-based (phytocannabinoids) and endogenous (endocannabinoids).

Phytocannabinoids are naturally occurring compounds produced by the Cannabis Sativa L. genus of plants, while endocannabinoids are produced within our own bodies. The most well-known and researched phytocannabinoids are THC and CBD.

 

How do cannabinoids work?

 

Cannabinoids interact with receptors in our body's endocannabinoid system, as well as a range of other neuroreceptors. These interactions can affect a wide range of bodily functions, including mood, appetite, pain perception, and inflammation.

 

Is CBD legal?

  

Yes, here in the UK, CBD products that contain less than 0.2% THC or less than 1 mg of CBD per container are legal for sale and consumption, but they cannot be advertised as medical products. Over the counter CBD products in the UK are classed as Novel Food Items.
