Fiscal Impact through Fiscal Year 2017 (executive summary)
Initiative 502 would license and regulate marijuana production and distribution; tax marijuana sales; earmark marijuana-related revenues; and specifically prohibit driving under the influence of marijuana. The total fiscal impact on state and local government revenues, expenditures and costs is indeterminate due to the significant uncertainties related to federal enforcement of federal criminal laws related to marijuana. However, the initiative’s provisions related to driving under the influence of marijuana, which are not affected by federal criminal law enforcement, are estimated to generate known state fee revenue of $4,295,000 and known state agency costs of $2,754,000 over five fiscal years.
