Date: October 10, 2023 - October 12, 2023

Event Location:  Virtual Only

Organized by: ASTM Committee D37 on Cannabis



About the Event

The Symposium on Contaminants in the Cannabis and Hemp Industry and Their Impact on Consumer Safety will be held October 10, 2023 through October 12, 2023. The Symposium is organized by ASTM Committee D37 on Cannabis, and will be held virtually.  The language of the Symposium will be English.


Objective and Scope

This symposium will provide a forum for evaluating the current evidence and gaps regarding the presence and measurements of contaminants that pose a risk to consumer health and safety in cannabis and hemp products with a focus on evaluating the sources of contamination (including cultivation, plant uptake, extraction, processing, manufacturing, packaging, and delivery, etc.) and how they can be mitigated.

The information presented will provide a foundation for the development of new standards and specifications related to conducting risk assessments based on common sources of contamination in the Cannabis/Hemp industries. The information will enable sound approaches to identify and mitigate contaminants.

Topics for this symposium include, but are not limited to regulatory limits, standards development toxicity impact, test methods, vaping concerns and other relevant issues for the following contaminants:

  • Elemental Impurities
  • Pesticides
  • Microbials
  • Other Contaminants of Interest


Abstract Submission

To participate in the symposium, authors must submit a 2 to 3-page extended abstract using the appropriate ASTM Extended Abstracts template provided in the Abstract Submission Portal no later than March 31, 2023. To ensure your abstract was received into the ASTM database, please email and let us know that you have submitted an abstract.

To be considered, abstracts must include a clear definition of the objective and approach of the work discussed, pointing out material that is new, and present sufficient details with regard to results generated. The presentation and extended abstract must not be of a commercial nature, nor can it have been previously published in its submitted form. To be considered, authors must ensure their abstract is complete to allow for careful assessment of the paper's suitability for this symposium. Authors will be notified via email by May 5, 2023, of their paper’s acceptability for presentation at the symposium.

The extended abstracts will be included in the symposium program booklet, but will not be peer- reviewed or copy-edited, so accepted authors will need to submit material suitable for distribution.


Publication Information

Based on the technical quality of the abstracts, presenters may be contacted to submit a full paper for a planned special section of ASTM’s Journal of Testing and Evaluation (JoTE). You will be notified by June 15, 2023, if the Editors would like you to submit a full paper for the special section. Please note that all submitted papers are subject to peer review by two independent reviewers.

Manuscripts to be peer reviewed for the special section are due online at the ASTM Editorial Office no later than October 1, 2023. The corresponding author will receive a copy of their paper in an electronic format. All published authors will have the opportunity to purchase reprints of their papers at a nominal cost.
