Understanding cannabinoids and their varied roles

Cannabis contains a wide variety of chemical compounds, among which cannabinoids are a prominent group. While THC and CBD are the most recognised, they represent only a portion of the plant's chemical profile.

According to a review published in the International Journal of Molecular Sciences, cannabinoids interact with the body’s endocannabinoid system (ECS), a network of cannabinoid receptors, endogenous ligands, and metabolic enzymes. This system plays a role in various physiological functions.

While much of the existing research has focused on well-known compounds such as THC and CBD, there is increasing scientific interest in lesser-studied phytocannabinoids like cannabigerol (CBG) and cannabinol (CBN), which do not produce the same psychoactive effects associated with THC.

These minor cannabinoids are not as abundant as THC or CBD, but they are of growing interest in scientific studies. Each compound has a unique chemical structure, and researchers are working to understand their distinct properties and interactions within the endocannabinoid system.

The significance of the Endocannabinoid System

The endocannabinoid system (ECS) is a biological network identified in humans and other mammals. It consists of receptors and signalling molecules that are currently being studied for their roles in various internal processes.

Cannabinoids found in plants like cannabis are structurally similar to compounds that occur naturally in the body. Scientific investigations continue to explore how these external cannabinoids may interact with the ECS and what this might reveal about their characteristics.

The emergence of minor cannabinoids in research

Research into cannabinoids has grown, focusing on minor ones like CBG and CBN. These compounds are being studied for their unique properties. They were once overshadowed by THC and CBD but are now getting more attention.

CBG and CBN are key areas in cannabinoid research. Based on a 2023 study published in the journal Biochemistry, CBG is referred to as the "mother of all cannabinoids" because it serves as the precursor to other cannabinoids.

Both CBG and CBN are attracting attention as researchers explore the broader range of properties that minor cannabinoids may possess.

Ongoing studies aim to better understand how CBG and CBN function and what sets them apart. Their distinct characteristics have made them a subject of interest in scientific investigations into the cannabis plant’s lesser-known compounds.

Common minor cannabinoids: CBG, CBN, and CBC

Cannabis research has expanded to include lesser-known compounds such as CBG, CBN, and CBC. These are increasingly used in the development of non-combustible cannabis-derived products. They are also of interest for applications requiring specific cannabinoid profiles.

CBG (Cannabigerol): The mother of all cannabinoids

CBG is often referred to as the 'mother of all cannabinoids' because it is a precursor to several other cannabinoids. It plays a foundational role in the formulation of various cannabis-derived products. CBG is non-psychoactive, making it suitable for product lines that do not produce intoxicating effects.

CBN (Cannabinol): Mild and non-intoxicating

CBN is gaining interest in research due to its origin as a breakdown product of THC. It is non-psychoactive and is being examined for its unique chemical properties. This has led to its inclusion in formulations where minimal psychoactivity is preferred.

CBC (Cannabichromene): A lesser-known compound

CBC is another non-psychoactive cannabinoid that has become a topic of scientific inquiry. It is being evaluated for its potential uses in product development involving minor cannabinoids. Its distinct profile adds to the growing variety of options in cannabinoid-based applications.
