What is delta-8 THC (Delta-8 tetrahydrocannabinol)?

Most people familiar with cannabis can name THC or CBD—but far fewer have heard of delta-8 THC. Despite being one of the many compounds found in the cannabis plant, delta-8 remains a lesser-known cannabinoid that’s increasingly attracting both interest and debate.

Delta-8 THC, or delta-8 tetrahydrocannabinol, is a naturally occurring cannabinoid found in small amounts in the cannabis plant. It is structurally similar to the more well-known delta-9 THC, but it behaves a bit differently.

With more than ten years of practical experience working with cannabinoid profiles at Formula Swiss, I’ve seen how much the industry’s understanding has evolved.

I remember when delta-8 was rarely mentioned outside of lab discussions, now it regularly comes up in formulation planning and regulatory reviews. Delta-8 is a great example of a compound that was once overlooked but is now gaining momentum in both research and product development.

The science behind delta-8 THC

Delta-8 THC is one of the many cannabinoids found in the cannabis plant. It shares much of its chemical structure with delta-9 THC—the compound more commonly linked to cannabis—but the two differ in the position of a key double bond.

In delta-8 THC, the double bond is on the eighth carbon atom; in delta-9, it’s on the ninth. This small structural difference affects how each compound interacts with cannabinoid receptors in the body, which may influence their effects. These distinctions are part of the reason delta-8 is being more closely studied in cannabis research.

What are cannabinoids?

Cannabinoids like delta-8 THC are naturally occurring compounds in the Cannabis sativa plant. A 2018 review published in the International Journal of Molecular Sciences stated that these compounds interact with the body’s endocannabinoid system, which is involved in various biological functions.

While research into this system is ongoing, its receptors are recognised for their involvement in signalling processes throughout the body.

The chemical structure of delta-8 THC

Delta-8 THC shares a similar molecular framework with delta-9 THC, but with a slight variation: the position of a double bond on the carbon chain.

In delta-8, this bond is on the eighth carbon atom, whereas in delta-9, it is on the ninth. Though seemingly minor, this distinction contributes to how each compound behaves during interactions with cannabinoid receptors.

Delta-8 THC and delta-9 THC

While delta-8 THC and delta-9 THC are structurally alike, their subtle chemical difference leads to varying patterns of interaction with receptors in the brain. This may influence their overall effects and how they are perceived.

Delta-8 THC is often reported to produce effects that are less intense than those associated with delta-9 THC, though individual responses can vary.

How is delta-8 THC manufactured?

Delta-8 THC occurs naturally in the cannabis plant, but only in very small amounts—typically less than 1%. Because of this low concentration, it’s rarely extracted directly. Instead, most delta-8 THC on the market is produced through a conversion process using CBD extracted from hemp.

The process begins with the isolation of CBD from hemp using standard extraction methods such as CO₂ or ethanol extraction. Once purified, the CBD undergoes a chemical reaction—often using acid catalysts—that rearranges its molecular structure into delta-8 THC. This synthesis must be carried out under carefully controlled laboratory conditions to ensure safety, accuracy, and compliance with regulatory standards.

Due to the nature of the conversion process, strict quality control is essential. The final product should be thoroughly tested by independent laboratories to verify cannabinoid content and to confirm the absence of residual solvents, heavy metals, or other impurities. Responsible manufacturers also provide Certificates of Analysis (COAs) to ensure transparency and product safety.

This approach allows producers to make delta-8 THC from legally sourced hemp, but the reliance on chemical conversion has raised important discussions within regulatory and scientific communities about product safety and legal classification.

Extraction and synthesis of delta-8 THC

The process of producing delta-8 THC typically begins with extracting CBD from hemp. This CBD is then chemically converted into delta-8 THC through a controlled reaction, allowing for a stable and usable form of the compound.

The choice of extraction method affects the product's quality and safety. Methods like CO2 extraction or solvent-based ones are used based on what's needed and what's available.

Quality control in delta-8 THC production

Maintaining high standards is a priority in the production of delta-8 THC. Each stage of the process is carefully monitored to help ensure that the final product meets strict cleanliness and composition criteria. Independent laboratory testing is conducted to verify the levels and presence of delta-8 THC and to check for any unwanted substances.
