    WK69533

    1. Scope

    1.1 This practice provides a method for storing samples consistent with the specifications in the ASTM Specification for Real-Time Storage and Testing of Cannabis Plant Material (unpublished in development). 1.2 The primary scope of this practice is cannabis plant material for smoking. However, the same plant material may have other uses including analytical standards and samples for determining degradation products. Some regulatory agencies require use by dates. Others will follow, especially if an age-related problem develops. One can anticipate that the plant material will ultimately be regulated as a drug. Plus, vendors will be asked by customers for guidance on how to store the plant material for future use, that is, smoking. 1.3 Plant material designed for vaping is outside the scope of this practice. 1.4 Accelerated testing protocols of degradation are outside the scope of this practice. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of international Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

    Rationale

    Cannabis plant material changes with time. Conditions of harvest, drying, processing and storage all may affect the rate of change. Use-by-dates are required by some jurisdictions for consumer protection. Determining use-by-dates requires data obtained over different storage periods. The influence of other variables needs to be tightly controlled, by rigorous control of the post-harvest process. The critical quality attributes for cannabis products for smoking are different than other cannabis products. Controlling water vapor is one example. If the material is too wet, microbes will grow. Microbes can produce aflatoxins, which are very toxic to humans. If the material is too dry, it burns too fast for smoking.

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