What is CBG?

CBG, short for cannabigerol, is a non-psychoactive cannabinoid found in cannabis plants like hemp and marijuana. Unlike popular cannabinoids such as THC and CBD, CBG does not cause any intoxicating effects. CBG is actually the precursor molecule from which THC, CBD, and other cannabinoids are synthesized. It starts out as CBG in the early stages of the plant's growth and is then converted into other cannabinoids through enzymatic processes.

Unleashing the Potential of CBG: An Exhaustive Guide to Cannabigerol

CBG is considered the "parent" cannabinoid and is abundant in hemp plants, which typically contain higher levels of CBG than marijuana strains. As research into the potential therapeutic uses of cannabis compounds continues, scientists are taking a closer look at CBG and its unique effects within the human body's endocannabinoid system.


Despite having a similar molecular structure, CBG, CBD, and THC have distinct differences:

  • THC is the main psychoactive compound in cannabis that generates the "high" feeling. CBG and CBD are not intoxicating.
  • CBG is the precursor from which THC and CBD are synthesized during plant growth.
  • CBD is the second most abundant cannabinoid after THC. CBG levels are typically much lower.
  • CBG and CBD are both non-psychoactive and may have therapeutic benefits.
  • CBG, THC, and CBD all interact with the body's endocannabinoid system but affect receptors differently.

While CBD is widely available and thoroughly researched, the therapeutic potential of CBG is now gaining more interest. CBG is not scheduled as an illegal substance like THC and can be shipped across state lines. Research is ongoing into the entourage effect of combining CBG with other cannabinoids like CBD.

How is CBG Produced and Consumed?

Extraction methods for CBG

To produce CBG, extraction techniques are used to isolate it from hemp or cannabis plants. Some common CBG extraction methods include:

  • CO2 extraction - Using pressurized carbon dioxide to selectively extract cannabinoids.
  • Hydrocarbon extraction - Using solvents like butane or ethanol to extract oils.
  • Olive oil extraction - Infusing plant material into olive oil to leach out cannabinoids.
  • Distillation - Separating cannabinoids through temperature and vacuum distillation.

CO2 extraction is the most common method used by commercial CBG producers to obtain highly pure compounds. Hydrocarbon extraction can also isolate CBG efficiently but may leave behind residual solvents if not done properly.

Different consumption methods and dosing

Once extracted, there are many ways CBG can be consumed:

  • Oils/tinctures - CBG concentrates that can be taken sublingually or added to food/drinks.
  • Edibles - CBG infused into food products like gummies or chocolates.
  • Capsules - Allow for standardized CBG doses in pill form.
  • Topicals - Lotions, balms, or creams infused with CBG for skin application.
  • Vaping/smoking - Inhaling vaporized CBG concentrate or CBG-rich flower.

Dosing is very individualized and depends on the delivery method. Many people start around 5-25 mg of CBG per day and increase slowly from there looking for the optimal dose. Consistency is important as effects may take several weeks to become apparent.

Comparison with CBD

There are some key differences between CBG and the better-known CBD:

  • CBG is less abundant in plants and more expensive to produce.
  • CBG has been less extensively researched than CBD so far.
  • CBG may have greater affinity for CB1 and CB2 receptors than CBD.
  • CBG is thought to have stronger anti-inflammatory effects.
