New Funding to Explore the Impact of Cannabis Retail Markets in Washington

September 25, 2025

Washington’s cannabis market has evolved rapidly since legalization, with ongoing expansion in the number of retail stores, declining prices, increasing product potency, and proliferation in the number and types of cannabis products available. The long-term implications of these market changes on health-risking patterns of cannabis use remain unclear. New funding obtained from the National Institute on Drug Abuse will be used to examine how cannabis store availability and marketplace characteristics shape long-term patterns of cannabis use among parents and youths in Washington State. The project will use data from the Seattle Social Development Project – The Intergenerational Project (SSDP-TIP), led by principal investigator Jennifer Bailey, with analyses led by Vi Le. Findings from this administrative supplement will inform the development of regulatory policies that minimize underage and health-risking cannabis use behaviors.
