Most people are familiar with the popular cannabinoids THC (delta 9 THC) and CBD; both serve many purposes — medicinal and recreational.

Researchers have identified over 100 cannabinoids, and THC and CBD users often wonder where the others stack up in terms of potency.

This article serves as a guide to cannabinoid potency and will help you find the one that delivers the most intense psychoactive experience.

What Are Cannabinoids?

Cannabinoids are compounds that interact with the endocannabinoid system.

The term most often refers to constituents of cannabis plants that take effect on this series of receptors and signalers. Popular cannabinoids include delta 9 THC (often just called “THC”), CBD, delta 8 THC, and CBG.

How Do Cannabinoids Work?

Cannabinoids bind to or block receptors in our endocannabinoid systems, namely CB1 and CB2 receptors.

These receptor sites in our bodies are closely linked to most bodily systems and help maintain balance, even our thought processes, mood, attitude, outlook on life, and perception of pain and pleasure.

Cannabinoid receptors help control neurotransmitters and hormones in our bodies, allowing cannabinoids like THC and CBD to affect our health.

Which Cannabinoid Is the Most Potent?

The most potent cannabinoid is tetrahydrocannabiphorol, more commonly referred to as THCP.

THCP has seven carbon atoms in its alkyl side chain, making it the most potent cannabinoid that currently exists. For comparison, delta 9 THC has only five carbon atoms. THCP is believed to be up to 33 times more powerful than THC.

List of The Strongest Cannabinoids According To Potency

Not all cannabinoids are created equal — some are much, much stronger than others. We have created a list of the major cannabinoids found in cannabis plants to understand better their effects.

We’re basing this ranking on a combination of personal testing and scientific research exploring the binding capacity of each cannabinoid.

1. THCP (Strongest Natural Cannabinoid)

THCP is at the top of the spectrum of cannabinoid potency by a long shot. Early research suggests it’s up to 33 times more potent than delta 9 THC, but after testing it ourselves, we’d place it somewhere in the 10X range.

There are other cannabinoids that are stronger, but they don’t occur in nature and tend to come with a lot of risks. THCP is found naturally in both hemp and marijuana in small concentrations.

2. THC-O

THC-O is a THC analog that has the same number of carbon atoms in its alkyl side chain. The key difference with this cannabinoid is the acetate group that replaces the hydroxy group found in delta 9 THC with an acetate group.

This small change makes THC-O significantly more bioavailable than any other form of THC. Its increased potency comes from a higher uptake of the molecule into the bloodstream and brain.

This cannabinoid is later metabolized into delta 9 THC, which then exerts the psychoactive effects.

THC-O is considered around 3 times as potent as delta 9 THC.

3. Delta 9 THC

Delta 9 THC is the most popular and well-known cannabinoid.

It’s also the most prevalent psychoactive cannabinoid in marijuana plants, so other cannabinoids’ are compared to it. This is our baseline for assessing the relative potency of all other cannabinoids on this list.

Delta 9 THC has five carbon atoms in its alkyl side chain and a hydroxy group that allows the strong binding capability to CB1 receptors.

4. HHC

Hexahydrocannabinol (HHC) is a more stable form of THC. It’s very similar in chemical structure to THC but is referred to as “hydrogenated” because it contains additional hydrogen atoms that break the double bond (delta) found on other types of THC molecules.

The added hydrogen atoms produce a less snug fit into CB1 receptors, so HHC is about 80% as potent as delta 9 THC.

5. Delta 8 THC

Delta 8 THC is nearly identical to delta 9 THC in molecular structure. However, the difference between delta 8 and delta 9 is that the double bond of the carbon chain in THC is in the eighth position.

Our Delta 8 THC is around 50-65% as potent as delta 9 THC. Most users report a clear-headed psychoactive experience and relaxation with a lower risk of unwanted side effects, like paranoia and anxiety.

6. Delta 10 THC

As the name suggests, delta 10 THC is also almost identical in structure to delta 9 THC. This cannabinoid has the double bond in the carbon chain shifted to the tenth position, the main difference of delta 10 and delta 9 THC.

Delta 10 THC is around 50% as potent as delta 9 THC. Most users report improved focus and attention, as well as a boost to energy and mood.

Tetrahydrocannabivarin (THCV) has just three carbon atoms in the alkyl side chain, but it’s otherwise identical to delta 9 THC. With the minimum number of carbon atoms in the side chain to still produce a psychoactive effect, THCV is approximately 25% as potent as delta 9 THC.

8. CBN

Cannabinol (CBN) has five carbon atoms in the alkyl side chain, just like delta 9 THC. However, it has two additional double bonds in the carbon ring and two fewer hydrogen atoms.

CBN is formed as THC breaks down and thus maintains some of its psychoactive properties.

The differences in CBN’s molecular structure might be minor, but they make it far less likely to bind to CB1 receptors. CBN is approximately 10% as potent as delta 9 THC.

9. CBD & Others (Non-Psychoactive)

The rest of the cannabinoids can all be listed in the same category as they are entirely non-psychoactive. Cannabinoids such as CBD, CBC, CBDV, CBCV, and THCC don’t directly activate the CB1 receptors and therefore won’t make users feel high. Even very large doses of these cannabinoids won’t cause psychoactive properties. You can also check our recent article about CBD and its difference to delta 8.

However, many of them will cause some form of body sensation. Users may feel a little bit heavier or lighter and more relaxed overall.

10. CBG (Anti-Psychoactive)

If you compare CBN to CBG, the latter is in a class of its own because not only is it non-psychoactive — studies have found it actually negates some of the psychoactive properties of other cannabinoids, like THC.

As such, this cannabinoid is sometimes used in combination with THC to reduce the psychoactive “load” of these products. This is good for people who want to experience the health benefits of THC but don’t necessarily want to feel super stoned in the process.

What Makes a Cannabinoid Potent?

“Potency” is the measure of a cannabinoid’s ability to cause a psychoactive experience. Basically, the more potent the cannabinoid, the more intense your psychoactive experience will be.

On a more scientific level, the potency of a cannabinoid is really a measure of how well it binds to or blocks endocannabinoid receptors.

For THC and its psychoactive analogs, potency depends on the number of carbon atoms in the alkyl side chain of the molecule. A molecule with eight carbon atoms would fit perfectly in our CB1 and CB2 receptors, making it the most potent a cannabinoid could possibly be. However, no natural cannabinoid has this many carbon atoms in the alkyl side chain.

Molecules with fewer than three carbon atoms will not bind with endocannabinoid receptors at all, so they won’t provide a psychoactive experience. Those with three offer a mild high, and each additional carbon atom increases the potency.

Other changes to a cannabinoid’s structure can affect how well it binds to endocannabinoid receptors and, as a result, its potency.

Key Takeaways: What’s the Most Potent Cannabinoid?

When it comes to cannabinoids, potency refers to the molecule’s ability to bind to our endocannabinoid receptors. Higher potency means a more intense psychoactive effect or high. Those looking for a more intense feeling of euphoria and boosted mood from cannabinoids naturally look for the most potent option.

THCP is the most potent cannabinoid currently known, about 30x that of delta 9 THC. It has more carbon atoms in its alkyl side chain, meaning it binds more readily and more tightly to receptors in our endocannabinoid system.

There are many other psychoactive cannabinoids with varying potencies, including THC-O, HHC, delta 8 THC, delta 10 THC, THCV, and CBN. They might be less potent, but they’re still powerful.
