Working with Doctors for Cannabis Regulation and other stakeholders, David L. Nathan, MD, proposed the Universal Cannabis Product Symbol (UCPS) in 2019. After its publication in 2020, a broad discussion with various stakeholders led to a series of changes to the UCPS. Working with the standards organization ASTM, the authors of this paper co-designed a modified version of the UCPS, which was renamed the International Intoxicating Cannabis Product Symbol (IICPS). This article presents the IICPS and next steps for the industry to start implementing its use.

This article proposes cannabis labeling standards to serve as a foundation for the regulation of cannabis product packaging for both medical and adult-use products.
