In light of COVID-19 (coronavirus) and our priority for the health and welfare of our members and staff, ASTM International has decided that it is inadvisable and impractical to hold the committee meetings in Prague on April 27-May 1. The decision was based on several factors, including, but not limited to:

    • Continued review of information and recommendations from the U.S. Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO) and other governmental bodies.
    • Input from our members whose organizations are increasingly concerned with travel and the large gathering in Prague.
    • Watching the expanding trajectory of the coronavirus.

    Staff managers will be contacting committee leaders to plan alternatives for conducting committee business. For any committees that collected money for events, ASTM will work to issue refunds as necessary. Attendees are responsible for cancelling their own hotel reservations.

    Looking forward, we will rely on these and other relevant criteria and input points to assess the status of future scheduled ASTM meetings and events. Please consult our meeting webpage for the most up-to-date information. Thank you for your understanding and continued commitment to ASTM International.

    About the Event

    The Workshop on Measurement of Elemental Contaminants in Cannabis and Hemp Consumer Products will be held Monday-Wednesday, June 28-30, 2021. Sponsored by ASTM Committee D37 on Cannabis, the workshop will be held virtually.

    Objective and Scope

    Heavy metals are a known consumer safety hazard that are largely not being addressed by the cannabis/hemp industry. Currently four (4) heavy metals (Pb, Cd, As, Hg) are required by thirty-six (36) states in the United States and Canada where consumption of cannabis/hemp consumer products for various purposes is legal. However, there is compelling evidence in the public domain that at least another 10 elements could be of potential concern derived from the cultivation process and growing environment including soil, grow medium, fertilizers, nutrients, water, and growth enhancers etc.

    In addition, the manufacturing of various cannabinoids can also lead to a further increase of these elemental contaminants through the processing, extraction, purification, packaging, dispensing systems, and device hardware, which can represent significant safety risks to consumers. Moreover, Maryland also requires Ba, Se, Cr, and Ag while New York State also includes Zn, Cr, Cu, Ba, and Sb. Clearly there needs to a better understanding of the toxicity role of these additional elemental contaminants, and, in particular, how they are taken up by the plant and whether they find their way into consumer products.

    This workshop will provide a broad perspective and awareness of the current knowledge of elemental contaminants in cannabis/hemp consumer products, communicate their significance, and as a result, educate users, cultivators, processors, testing labs, and regulators within the cannabis/hemp community of their potential risk.

    The following topics will be addressed in the workshop:

    • The most current research detailing the mechanisms for metal uptake into a cannabis plant based on growing conditions and soil chemistry.
    • Optimization of analytical methodology used to measure heavy metals in cannabis/hemp consumer products.
    • Lessons learned from regulating heavy metals in drug products and using a scientifically risk-based approach to predict elemental impurities derived from the manufacturing process.
    • Toxicological impact of heavy metals and the industry’s responsibility for ensuring consumer health and safety.
    • The current state of the art research in phytoremediation and phytoextraction techniques.
    • The most recent research in characterizing elemental contaminants in vaping liquids and aerosols produced by electronic nicotine delivery systems (ENDS) and electronic cannabis delivery systems (ECDS).

    Scientists at the CDC, FDA, NIST and USP are scheduled to present at this truly groundbreaking event. Each presentation will be 30 minutes in duration, followed by 15 minutes of Q&A and discussion.

    The language of the workshop will be English.
