Open Publication PDF

Adam Darnell, Rebecca Goodvin, Sara del Moral, Casey Hicks, Paige Wanner, Eva Westley - December 2018

Initiative 502 (I-502) legalized recreational cannabis for adults in Washington State. The law directs a portion of cannabis revenues to be spent on substance abuse prevention and treatment services that have been demonstrated to be effective. Specifically, state law requires at least 85% of programs funded by cannabis revenues to be evidence-based or research-based and up to 15% to be promising practices. In this inventory, we rate the research evidence for programs intended for the prevention or treatment of youth substance use, and we identify those specifically effective for marijuana. The 2018 Washington State Legislature directed WSIPP to update this inventory. This is the third update in the series.
