New Specification for Medicinal-Use Cannabis Inflorescence

1. Scope

1.1 This specification defines the specifications (appropriate tests, their analytical methods, and acceptance criteria) for the identification, strength (for example, cannabinoid content), and purity (for example, limits for contaminants) for medicinal-use cannabis inflorescence. 1.2 This specification references approved analytical methods used to verify the specifications and, in the absence of approved analytical methods, a suggested method for validating such specifications. 1.3 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations before use.

This standard defines the metrics for identification, cannabinoid specifications, and limits for contaminants for medicinal-use cannabis inflorescence. This specification aligns with multiple specifications practiced globally, as referenced throughout, and thus is inferred to be attainable. Businesses engaged in the cultivation, processing, buying, and selling of medicinal-use cannabis inflorescence use this standard for the creation of contract stipulations and a basis for ensuring that products meet producer claims of cannabinoid dominance and ratio as well as minimum safety and consistency profiles. Testing laboratories use this standard to verify that medicinal-use cannabis inflorescence meets the specification claims within contracts and that unknown samples fall into the appropriate cannabinoid dominance type. Testing laboratories engaged in providing methodology shall use test methods referenced within this specification or those that have been validated per ASTM D8282 with appropriate validation documentation.

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