Why two products with the same CBD concentration don't have the same effect

When buying CBD, many consumers assume that two products with the same CBD percentage will produce the same effects. However, the reality is much more complex. Let me explain why an identical CBD percentage never guarantees an identical experience.


Things to remember

  • The CBD percentage is just one indicator among many other criteria.

  • Secondary cannabinoids, terpenes, and extraction quality have a significant impact on the experience.

  • Every person reacts differently to CBD, even at the same dosage.


The CBD content tells only part of the story about the product


A figure that is often highlighted


When you visit a CBD shop or an online CBD store, the first piece of information you notice is often the percentage of cannabidiol. 10%, 20%, 30%, or more: these numbers immediately catch your eye.


However, they alone do not allow for an accurate prediction of the effects experienced. The CBD content simply indicates the amount of cannabidiol present in the product. It does not provide information about all the other molecules naturally present in the extract.


Two 20% oils can be very different


Let's take a simple example. Two CBD oils both list 20% CBD. On paper, they seem equivalent.


However, theone may come from a full-spectrum extract rich in terpenes and secondary cannabinoids, while the other may consist almost exclusively of CBD isolate.


The displayed percentage remains the same, but the overall composition changes drastically. This difference directly influences the consumer experience.


CBD never acts entirely on its own


The hemp plant contains several hundred natural compounds. Cannabidiol is just one part of this whole


When these molecules are retained during extraction, they can interact with one another and alter the way the product is perceived; this is known as the entourage effect. This is why two products containing exactly the same amount of CBD can produce different effects.

The Importance of Other Cannabinoids


The Role of CBG


Cannabigerol, often referred to as CBG, is also attracting attention. Even when present in small amounts, it contributes to the product’s overall profile. The effects of CBG are therefore noticeable in the final product.


An oil that combines CBD and CBG could provide a experience different from that of an oil containing only cannabidiol.


CBN and Other Cannabinoids


Hemp also contains CBN, CBC, and other minor cannabinoids. Their concentrations are generally low, but their presence alters the overall balance of the extract.


It's kind of like a recipe, really. Two dishes can contain the same main ingredient yet offer very different flavors thanks to the secondary ingredients.


The entourage effect


Experts often use the term “entourage effect.” This theory suggests that cannabinoids and other compounds in hemp work better together than they do separately.


Although research continues to explore this phenomenon, it is currently one of the main explanations for the differences observed between two products that nevertheless have the same CBD content.

Terpenes significantly alter the experience


What are terpenes?


Terpenes are aromatic molecules naturally found in hemp. They are what give the flowers their fruity, woody, citrusy, spicy, or floral scents. 


But their role isn't limited to scent; they also contribute to the product's overall identity.


Why They Matter So Much


Two oils containing 20% CBD may have completely different terpene profiles. One may be rich in myrcene, while another may contain more limonene or pinene. This difference affects how the product is perceived by the user.


That's actually one of the reasons why some CBD flowers —even though they appear similar on paper— offer noticeably different experiences.


A criterion that is still underestimated


Many consumers focus solely on the CBD content. However, experienced enthusiasts are also interested in the terpene profile. This information often provides more insight into the product’s characteristics than the cannabidiol percentage alone.

The extraction method also makes a difference


Not all extractions are created equal


Extraction determines which molecules are retained in the final product.


Some methods better preserve terpenes and secondary cannabinoids. Others prioritize more thorough purification. The result can therefore vary significantly depending on this stage of the process.


Full-spectrum, broad-spectrum, or isolate


A full-spectrum product retains most of the compounds naturally found in hemp.


A broad-spectrum product generally removes THC while retaining some of the other molecules.


The isolate, on the other hand, contains almost exclusively pure CBD.


Two products containing 20% CBD can fall into these three categories and result in very different experiences.


The quality of the raw material


The origin of the hemp also plays a role in the final experience. A plant grown under optimal conditions generally produces a richer and more stable profile. The quality of the raw material directly influences that of the final product.

Your body also influences the effects


Everyone functions in their own way


Even with the best product on the market, results vary from person to person. Your weight, metabolism, diet, and even your experience with CBD can influence how you feel.


The Endocannabinoid System


CBD interacts, in particular, with the endocannabinoid system. However, this system has characteristics that are unique to each individual. This is one of the reasons why two users taking exactly the same product may report different experiences.


Consumption Habits


Frequency of use also plays a role in how it feels. Someone who is just discovering CBD may notice certain effects more easily than a regular user who is accustomed to this type of product.
