¿Qué es el CBG? Efectos, beneficios y diferencia con el CBD
CBG (cannabigerol) is often called the "mother of all cannabinoids" because nearly every other cannabinoid in the hemp plant — including CBD and THC — starts out as CBG. Yet CBG itself is still a niche compound that researchers are only beginning to understand. This guide explains what CBG is, how it is produced in the plant, how it compares to CBD, and what current research suggests about its role in the endocannabinoid system.
What is CBG?
CBG, short for cannabigerol, is a non-intoxicating cannabinoid found in the Cannabis sativa L. plant. Unlike THC, CBG does not produce a psychoactive "high". It is classified as a minor cannabinoid because most mature hemp plants contain only around 1% CBG by dry weight — compared to up to 20% or more for CBD or THC in their respective chemotypes.
The reason CBG is so rare in mature plants is biological: CBG starts its life as CBGA (cannabigerolic acid), which the plant uses as a precursor molecule. As the plant matures, enzymes convert most of the CBGA into the acidic forms of other cannabinoids — CBDA, THCA and CBCA. Only the small amount of CBGA that escapes this conversion remains, and once it is decarboxylated (typically by heat or UV light) it becomes the neutral CBG that consumers can buy.
Because CBG is the chemical "parent" of the major cannabinoids, it is sometimes described as the stem cell of the cannabis plant.
How is CBG produced?
There are two main ways to obtain CBG in usable quantities:
- Early harvest: Hemp is harvested while it is still young, before most of the CBGA has converted into other cannabinoids. This is labour-intensive and gives a lower total yield.
- Selective breeding: Specialised hemp cultivars have been bred to retain higher levels of CBGA throughout the plant's life cycle. These cultivars are the basis for most CBG flower and extract products on the market.
After harvest, CBG is extracted using the same methods as CBD — typically supercritical CO2 extraction or ethanol extraction — and can be processed into oils, isolates, capsules or smokable flower.
CBG vs CBD: what is the difference?
CBG and CBD share many traits — both are non-intoxicating, both come from hemp, and both interact with the endocannabinoid system. But their molecular structure and the way they bind to receptors differ in important ways.
| Property | CBG (cannabigerol) | CBD (cannabidiol) |
|---|---|---|
| Role in the plant | Precursor / "mother" cannabinoid | Major cannabinoid (end product) |
| Typical content in hemp | ~1% | up to ~20% |
| Psychoactive | No | No |
| Main receptor interaction | Binds directly to CB1 & CB2 receptors | Modulates indirectly, low CB1/CB2 affinity |
| Effect on appetite (research) | Studied for appetite-stimulating signals | Often associated with neutral/reducing signals |
| Entourage effect | Contributes as minor cannabinoid | Often the base compound |
| Legal status (NL, <0.2% THC) | Legal as hemp product | Legal as hemp product |
| Price | Higher (rare to produce) | Lower (widely cultivated) |
The key takeaway: CBD is what most people already know — a major cannabinoid present in large amounts and widely studied for general wellness. CBG is rarer, more expensive, and works differently at the receptor level. They are complementary rather than competing compounds.
How does CBG work in the body?
The human body has its own endocannabinoid system (ECS) — a network of receptors (mainly CB1 in the nervous system and CB2 in the immune system) that helps regulate processes like mood, appetite, sleep and inflammation responses. Plant cannabinoids such as CBG can interact with this system.
Research into CBG is still in an early stage, but laboratory and pre-clinical studies suggest that CBG binds directly to both CB1 and CB2 receptors — a different mechanism than CBD, which mostly modulates the system indirectly. CBG is also being studied for its interactions with other receptor systems, such as alpha-2 adrenergic and 5-HT1A serotonin receptors.
It is important to stress: most CBG research so far has been done in vitro or in animal models. Human clinical trials are limited. CBG is not a medicine and Lucky Hemp does not sell CBG products as treatments for any health condition. We sell CBG as a hemp ingredient that adults can explore as part of a balanced lifestyle.
Potential areas being researched
Scientific interest in CBG has grown rapidly over the past five years. Areas currently under investigation in academic literature include:
- Interaction with the endocannabinoid tone and general balance (homeostasis).
- The entourage effect — how CBG works together with CBD and other minor cannabinoids and terpenes.
- Cellular and pre-clinical work on inflammation pathways, appetite signalling and neurological models.
These are research directions, not health claims. Anyone considering CBG for a specific reason should speak with their doctor first, especially when other medication is involved.
CBG products at Lucky Hemp
At Lucky Hemp we focus on EU-grown industrial hemp with less than 0.2% THC. Our CBG flowers collection features dedicated CBG-rich cultivars — hemp varieties that have been selected for higher cannabigerol content than standard CBD strains. These flowers are popular with adult consumers who want to explore CBG specifically, or combine it with CBD flower for a broader cannabinoid profile.
Typical formats include:
- CBG flowers: dried hemp buds rich in cannabigerol, sold as a raw plant product for collectors.
- CBG-CBD hybrid flowers: cultivars with a balanced ratio of both cannabinoids.
- Extracts and oils: CBG can also be processed into isolates and full-spectrum oils.
Is CBG legal in the Netherlands?
CBG itself is not a controlled substance under Dutch law. Hemp products containing CBG are sold legally in the Netherlands as long as the THC content stays below the legal threshold of 0.2% and the product is sold as a non-consumable hemp product. Lucky Hemp ships CBG flowers and hemp products across the Netherlands and the EU within these legal limits.
Frequently asked questions about CBG
Does CBG make you high?
No. CBG is a non-intoxicating cannabinoid. It does not cause the psychoactive effect that THC is known for.
What is the difference between CBG and CBD in one sentence?
CBG is the precursor molecule from which CBD and other cannabinoids are formed, and it interacts more directly with CB1 and CB2 receptors than CBD does.
Why is CBG more expensive than CBD?
Because mature hemp plants contain only about 1% CBG. Producers either harvest hemp early or use special CBG-rich cultivars, both of which lower the yield per hectare compared to standard CBD hemp.
Can I combine CBG and CBD?
Yes, many users combine CBG and CBD products. The two cannabinoids are often described as complementary, and they are part of the so-called entourage effect when consumed together with other hemp compounds.
Is CBG legal in the Netherlands?
Yes, CBG products derived from EU-certified industrial hemp with less than 0.2% THC are legal in the Netherlands.
