The National Institute of Standards and Technology (NIST) is launching an interlaboratory comparison study aimed at helping labs make the accurate Tetrahydrocannabinol (THC) measurements needed to distinguish between hemp and marijuana. For this study, NIST will send samples of hemp and marijuana plant material to labs that will then measure the concentration of various compounds and report back to NIST. This study will help labs diagnose technical issues and increase measurement consistency across labs. More information and an enrollment link are available on the NIST website. Enrollment is open through February 5, 2021.
