New Specification for Grading Cured Cannabis Bud

1. Scope

The development and maintenance of standards and guidance materials for cannabis and its products and processes. The work of this committee will be coordinated with other ASTM committees and other organizations having mutual interest.


cannabis; quality; grading


Currently, cannabis consumers tend to buy the most THC for the dollar because thats the only metric that is (a) available to them and (b) simple enough for them to understand. This metric has flowed upstream to growers and breeders, pushing the THC levels ever-higher, sacrificing all other potential quality metrics on the altar of THC per dollar. Broadly speaking, the industry would prefer for consumers to buy the best quality cannabis that they can afford, but to effect this change, the industry must offer a new metric of quality. This metric, too, is likely to flow upstream, affecting the strains and methods used to produce cannabis commercially, therefore it should be determined before other cultivation standards. It is To Be Determined whether cannabis should be graded by subspecies (e.g., indica, sativa, auto-flowering, or hybrid), by use (e.g., to sleep, for creativity, for pain relief), by strain name, by chemovar, by genotype, etc. It is expected that buyers all along the supply chain will this cured bud grading standard (and the complementary fresh bud grading standard) to buy the best bud that they can afford. It is expected that buyers will need to be trained to apply the grading standard consistently, that is, to be certified as graders.

The title and scope are in draft form and are under development within this ASTM Committee.
