ASTM WK94959
New Specification for the Minimum Quality of Precision Fermented, Semi-Synthetic, and Synthetic Cannabinoids to be Sold into a Legal Market
1. Scope
1. Scope: 1.1. This standard shall define a set of minimum quality specifications for cannabinoids produced through: 1.1.1. Precision fermentation or other genetically modified biological mechanisms. 1.1.2. Creation or conversion from other cannabinoids. 1.1.3. Chemical synthesis. 1.2. This standard shall apply to any precision fermented, semi-synthetic, or synthetic cannabinoid regardless of regulatory classification. 1.3. This standard shall define a minimum purity concentration and maximum allowable botanically related substances, impurities, and contaminants for precision fermented, semi-synthetic, or synthetic cannabinoids. 1.4. This standard shall define test methods for verifying the defined quality attributes are within specification, when test methods are available; otherwise, criteria for the validity of test results shall be defined. 1.5. This standard shall define the label content specifications for consumer- and non-consumer-facing packaged denominations. 1.6. This standard shall not apply to cannabinoids produced through natural biological mechanisms of animals or plants. 1.7. This standard shall not apply to cannabinoid-containing products, including cannabinoid-containing substances, or cannabinoid-containing products incorporating precision fermented, semi-synthetic, or synthetic cannabinoids. 1.8. This standard shall not apply to any cannabinoid-based or cannabinoid-containing approved drug product.Keywords

The following specification was developed in collaboration with a diverse group of stakeholders representing cannabinoid synthesis subject matter experts, testing and investigative laboratories, product manufacturers, regulators, and consumers. The intent of this standard is to: ? Provide specifications for cannabinoids produced through precision fermentation, conversion, or chemical synthesis. Specifications shall include minimum concentration, allowable botanically related substances, impurities, and contaminants that must be controlled. ? Outline the test methods for verifying the defined constituents are within specification. The purpose of this standard is to provide a mechanism for reducing the number of unknown and uncharacterized peaks in a chromatography so that if an adverse event occurs from consuming the synthesized cannabinoid, it can be narrowed down to a singular peak rather than a sea of peaks and unknowns. This will help prevent concerns related to unknown by-products and incomplete conversions during the manufacturing process. Most safety issues cited by the FDA are directly related to the impurities found in these compounds and not with the compounds themselves. While most of the input for this standard did come from North America, an effort was made to solicit as much feedback from impacted global marketplaces as possible. This standard is only the beginning and attempts to address a major gap regarding impurity and contaminant specifications for cannabinoids produced through precision fermentation, conversion, or chemical synthesis. Please remember that ASTM International standards are living documents and are intended to be updated and revised over time. This initial version will not be perfect, but it will serve to provide marketplaces with the information they need to make informed decisions regarding cannabinoid requirements and regulations.
