Requirements for Cannabis Product Labeling by U.S. State.

Introduction

As more states allow for medical and nonregistered adult cannabis (i.e., marijuana) use, ensuring proper utilization should be a priority. Standardized labeling for foods and pharmaceutical drugs promotes consumer safety. This study investigated cannabis product labeling requirements in the United States. Materials and

Methods

Researchers compiled the requirements for cannabis product labeling across 31 U.S. states with medical cannabis programs from state regulatory publications.

Results

Information requirements ranged considerably by U.S. state. All states required delta-9-tetrahydrocannabinol content and manufacturer contact information, >80% of states required the batch number, health risks, production tracking, a cannabis symbol, cannabidiol content, children disclaimer, and an impairment disclaimer. There appeared to be a random pattern in requirements for other specific items. The relationships between the extent of cannabis product labeling requirements and the number of years that a state had a medical cannabis program or whether states allowed nonregistered adult use cannabis were not significant, although there was a trend for nonregistered adult use states to require more recommended label attributes.

Conclusion

A comprehensive framework for cannabis use is needed to protect the public, maximize benefits, and minimize harms and risks. Standardization of cannabis product labeling requirements would benefit consumers and promote safer and more effective usage of cannabis products.
