A Research Agenda to Inform Cannabis Regulation: How Science Can Shape Policy.

In the United States, changes to cannabis policy have outpaced scientific knowledge about cannabis, its effects, and the impacts of different policy approaches. Research barriers stem from key federal policies, including strict drug scheduling of cannabis, which comprehensively hinder the ability to conduct cannabis research, affecting state markets, evidence-based regulation, and scientific gains that could more effectively shape policy moving forward. The Cannabis Regulators Association (CANNRA) is a nonpartisan nonprofit organization that convenes and supports government agencies to facilitate information exchange and learning from existing cannabis regulations across US states and territories and other governmental jurisdictions.
