Initiative 502, passed by Washington voters in November 2012, legalized recreational marijuana use for adults in the state. The initiative directed WSIPP to evaluate the policy by considering benefits and costs across a number of key areas including public health, public safety, and criminal justice.
As part of this assignment, we reviewed the evaluation literature on 13 youth prevention programs. These programs are on the state Department of Behavioral Health and Recovery’s preliminary list of evidence-based programs with marijuana prevention outcomes.
