International Cannabis Policy Study

International Cannabis Policy Study Dashboard

To inform state policy with the best available evidence, LCB partners with the University of Waterloo and Dr. David Hammond on the International Cannabis Policy Study (ICPS). This is an annual, ongoing, and international survey designed to examine trends in cannabis policy and public health impacts. The LCB Research Program utilizes this evidence from Washington to develop insights and actively facilitates data sharing with other academic partners, such as the University of Washington.

Survey Findings for 2026 will become available in Summer 2027.
