The 2018 Washington State Legislature directed WSIPP to conduct additional cannabis research, supplemental to the ongoing benefit-cost evaluation of cannabis legalization authorized by Initiative 502 in 2012. For this supplemental work, WSIPP was directed to update its inventory of programs for the prevention and treatment of youth cannabis use; examine current data collection methods measuring the use of cannabis by youth and potential ways to improve on these methods; and identify effective methods used to reduce or eliminate the unlicensed cultivation or distribution of marijuana in jurisdictions with existing legal marijuana markets.
The updated inventory
was released in December 2018. The report on measures of youth use of cannabis
was released in June 2019. The report on cannabis diversion from legal to illegal systems will be submitted to the legislature by July 30, 2019.
