ASTM International Technical Committee D37 on Cannabis is pleased to be sponsoring the very first global Workshop on Measurement of Elemental Contaminants in Cannabis/Hemp Consumer Products.
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, growing, extraction, manufacturing and production processes.
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.
