The Process: Delta-9 Can Be Converted Too
FIX THE RULES, NOT THE PLANT — PART 2
How the same cannabinoid can reach the shelf through two different manufacturing pathways, and why Texas should regulate where chemical conversion occurs.
Two gummies can both contain 10 milligrams of “hemp-derived delta-9 THC.”
One may contain delta-9 extracted directly from cannabis.
The other may contain delta-9 manufactured by chemically converting CBD.
The package may not tell you which one you are consuming.
That is the regulatory gap.
Two Products. Same Label. Different Process.
Delta-8 and delta-9 are cannabinoid names. They are not manufacturing methods.
Cannabis naturally produces cannabinoid acids, including THCA and CBDA.
Through heat and time, those compounds become neutral cannabinoids such as THC and CBD. A manufacturer can extract and refine those plant-produced cannabinoids into an ingredient for a finished product.
That is the direct-extraction pathway:
Cannabis → extraction and refinement → delta-9 ingredient
But delta-9 can also be made through a different pathway. A manufacturer can begin with CBD isolate or CBD-rich extract and intentionally change that CBD into delta-9 THC through chemical conversion.
That is the conversion pathway:
Hemp-derived CBD → chemical conversion → delta-9 ingredient
Scientific research has documented CBD as a precursor for multiple THC isomers, including delta-8 and delta-9. Recent research has examined how reaction conditions affect which THC isomers are produced, while other researchers have studied delta-9 production through continuous-flow systems.
The target delta-9 molecule may be the same. The manufacturing history is not.
Why Convert CBD Into Delta-9?
Because CBD became an abundant, standardized and relatively inexpensive raw material.
The hemp industry produced large quantities of CBD-rich biomass and CBD isolate. When demand did not absorb all of that supply, CBD became a feedstock for manufacturing other cannabinoids.
A manufacturer can convert CBD into a concentrated delta-9 ingredient, purify it and measure it into large production runs of beverages, gummies, chocolates and other edibles. That supports consistent milligrams across thousands of servings.
Not every hemp-derived delta-9 product is made this way. Delta-9 can also be extracted directly from cannabis. That is precisely why the words “hemp-derived delta-9” do not tell the whole story.
Why the Process Matters
Chemical conversion is not automatically unsafe. Chemistry is part of modern manufacturing. The question is whether the reaction was performed in a qualified facility, properly controlled, purified, tested and documented.
Conversion may involve solvents, catalysts, heat, purification and other processing controls. If the process is poorly controlled, the material may contain residual starting material, processing chemicals, unintended cannabinoids, reaction by-products or other impurities.
FDA has raised concerns about contaminants and by-products associated with CBD-to-THC conversion. NIST-associated research has also documented unknown by-products that can complicate cannabinoid analysis.
A standard potency COA may tell us how much delta-8 or delta-9 was detected. It does not necessarily tell us who performed the conversion, what inputs were used, how the material was purified or what else the reaction created.
A potency result identifies the cannabinoid. A process record explains how it was made.
How Conversion and the 0.3% Rule Work Together
The 0.3% delta-9 THC standard entered federal law as the dividing line between hemp and marijuana. Texas then carried that percentage into its Consumable Hemp Program and applied it to finished products manufactured for human consumption.
That changed what the percentage did. It was no longer used only to classify cannabis growing in a field. It also became part of the formulation rules for gummies, beverages, chocolates and other products.
A manufacturer can produce or purchase a concentrated delta-9 ingredient, measure a specific number of milligrams into a much heavier finished product and formulate the product below the applicable percentage threshold.
Conversion can create the THC supply. The finished product’s weight creates room for the milligrams.
Texas did not merely legalize a crop. It created a Consumable Hemp Program around a plant-based percentage, and the market learned how to manufacture within it.
Texas Is Regulating the Molecule Instead of the Process
Texas DSHS currently states that only naturally occurring trace amounts of delta-8 THC are permissible and that products containing more than trace amounts may be detained and referred to law enforcement. The same guidance says consumable hemp products may contain delta-9 THC at no more than 0.3% on a dry-weight basis.
But CBD can be converted into both delta-8 and delta-9. Naming delta-8 does not, by itself, solve the manufacturing problem.
If chemical conversion is the concern, regulate chemical conversion. If residuals and by-products are the concern, require manufacturing controls and appropriate testing. If potency is the concern, regulate milligrams and serving sizes.
Those are different risks. They require different regulatory tools.
What Smart Process Regulation Looks Like
1. Regulate Conversion Where It Occurs
Texas should clearly distinguish extraction, refinement, decarboxylation, formulation and intentional chemical conversion. Whether the state prohibits certain conversions or permits them under strict controls, the requirement should attach to the facility performing the reaction.
That facility should be responsible for its starting materials, processing controls, purification, testing, records and finished cannabinoid ingredient.
2. Test the Input Once. Trace It Everywhere.
GMP does not require businesses to repeat the same upstream contaminant tests on every flavor, size and SKU when all of those products use the same properly tested cannabinoid input batch.
A representative sample from a homogeneous batch of distillate or isolate can be tested for the hazards associated with that input. The verified COA can then support every finished-product batch and SKU using that exact lot—provided the material remains properly stored, documented and traceable.
Finished-product testing should focus on what formulation and manufacturing can change, including:
· Cannabinoid potency per serving and package
· Homogeneity and dose consistency
· Microbial or stability risks created by the finished formulation
· Contaminants introduced through other ingredients or processing
· Label accuracy and other product-specific hazards
Test the input for the hazards it brings into the facility. Test the finished product for what manufacturing can change.
That is not less testing. It is smarter testing.
3. Tell People Which Cannabinoid Ingredient Was Used
Consumers and regulators should not have to guess whether the delta-9 was directly extracted from cannabis or converted from CBD.
A plain-language disclosure could state:
Cannabinoid Ingredients: Delta-9 THC distillate — directly extracted from cannabis
Cannabinoid Ingredients: Delta-9 THC isolate — chemically converted from CBD sourced from hemp
The label should also provide an easily accessible URL linking to more detailed batch and testing information within three clicks or fewer. The information should not require an account, app download or submission of personal information.
The label does not need to publish a proprietary formula. It should tell people what cannabinoid ingredient was used, how it was generally produced and where its supporting information can be verified.
4. Apply the Same Standard to Out-of-State Material
Texas cannot hold its own manufacturers to meaningful process standards while allowing converted material from another state to enter with nothing more than a finished-product potency report.
If a cannabinoid ingredient is sold in Texas, the manufacturing and documentation requirements should follow it into Texas.
5. Enforce at the Responsible Point
Retailers should verify required documentation and purchase from approved sources. But a retailer cannot reconstruct a chemical reaction by looking at a gummy, beverage or COA.
Enforcement should begin with the manufacturer that created the cannabinoid ingredient and the businesses responsible for placing it into the supply chain.
Regulate Where the Chemistry Happens
This is not an argument against chemistry. It is an argument for accountable manufacturing.
Delta-8 became the villain. Delta-9 became the acceptable alternative. But both can occur naturally, and both can be produced through chemical conversion.
The cannabinoid name tells us what the target molecule is. It does not tell us how the molecule was produced, whether the process was controlled, what else the reaction created or whether the finished ingredient was properly purified and documented.
Texas should stop trying to determine manufacturing history from the name printed on the package.
Follow the ingredient. Follow the records. Follow the supply chain. Regulate where the chemistry happens.
