Cannabis Legalization Evaluation

In November 2012, Washington State voters passed Initiative 502 to regulate and tax the use and sale of cannabis for persons twenty-one years of age and older. As part of I-502, WSIPP was directed to “conduct cost-benefit evaluations of the implementation” of the law. The evaluations must include measures of impacts on public health, public safety, cannabis use, the economy, the criminal justice system, and state and local costs and revenues.

A preliminary report was released in September 2015. The second required report was released in September 2017, and the third required report was released in September 2023. The last mandated report is due in 2032.

Previous Findings
Supplemental to the ongoing benefit-cost evaluation of cannabis legalization authorized by Initiative 502 in 2012, the 2018 Washington State Legislature directed WSIPP to conduct additional cannabis research. 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.

Recent Findings
Initiative 502 and Cannabis-Related Public Health and Safety Outcomes: Third Required Report
We describe findings from analyses of the relationship between non-medical cannabis legalization or licensed retail operations and various outcomes. First, we examined how cannabis possession misdemeanor conviction rates changed in Washington after the passage of I-502. Second, we examined how reported cannabis use has changed in Washington after the passage of I-502 compared to non-legalizing states. Last, we specifically focused on the impact of local access to licensed non-medical retailers. For these analyses, we examined how retail access relates to substance abuse and traffic safety outcomes within the state over time.

Reported Substance Use: Using national survey data, we compared changes in the rates of reported cannabis, alcohol, and other substance use in Washington after the enactment of I-502 and the start of a licensed retail market, relative to changes in comparable states that did not legalize non-medical cannabis.

Cannabis-Related Convictions: We examined how rates of cannabis possession misdemeanor convictions have changed since the enactment of I-502. We examined conviction rates separately for different ages, sex, and racial groups.

Traffic Fatalities: We examined the relationship between greater access to licensed non-medical cannabis retailers and the prevalence of fatal traffic collisions. We also examined the relationship between retail accessibility and the prevalence of drivers involved in a fatal crash who test positive for THC both alone and in combination with alcohol.

Substance Use Disorder Diagnoses: We examined the relationship between greater access to licensed non-medical cannabis retailers and the probability of cannabis use disorder, alcohol use disorder, or opioid use disorder diagnoses.

High School Outcomes: We examined the relationship between school proximity to an operational non-medical cannabis retailer and high school outcomes, including attendance, disciplinary outcomes, and high school graduation.

Effectiveness of the drug offender sentencing alternative (DOSA)

The 2020 Washington State Legislature directed WSIPP to evaluate the effectiveness of the drug offender sentencing alternative (DOSA). DOSA allows individuals to participate in treatment and community supervision in lieu of some (Prison DOSA) or all (Residential DOSA) of their incarceration sentence. This evaluation will examine whether participation in DOSA reduces recidivism and whether those effects vary for prison- and residential-based DOSA programs. The legislature directed WSIPP to repeat these evaluations on a regular schedule to continuously monitor the effects of the program.

An introduction to the ongoing report series that describes the development of DOSA can be found here. The initial evaluation report can be found here. Additional evaluation reports are due to the governor and the legislature on November 1, 2028, and every five years thereafter.

Creating Prison to Postsecondary Education Pathways

The 2021 Legislature passed 2SHB 1044 expanding the types of postsecondary education programs eligible for state funding in the Department of Corrections’ (DOC) incarceration facilities. The bill directs WSIPP to study recidivism, enrollment, and completion rates of incarcerated persons in the postsecondary education system after release from incarceration. The study will use data from DOC, the Washington Student Achievement Council, and the State Board of Community and Technical Colleges. The study must include the following:

  • Patterns and effects on post-release enrollment and participation in the community and technical college sector by individuals who, while incarcerated, participated in postsecondary education;
  • Differential outcomes for individuals participating in different types of postsecondary education courses, certificates, and degree programs;
  • Changes in enrollment and completion of postsecondary education courses, certificate programs, and degree programs due to the expansion in postsecondary education programming; and
  • Recidivism outcomes other than incarceration for those individuals who participated in postsecondary education while incarcerated.

A preliminary report is due to the Legislature on October 1, 2024, and a final report is due October 1, 2027.

Evaluation of the Reentry Community Services Program

The 2021 Legislature passed E2SSB 5304 which modified the state’s Reentry Community Services (RCS) program. The bill includes an assignment for WSIPP to update its evaluation of the RCS program and to broaden its benefit-cost analysis to include impacts on the use of public services and other factors. In addition, the bill directs WSIPP to examine the potential cost, benefit, and risks involved in expanding or replicating the RCS program. Finally, the bill asks WSIPP to examine what modifications to the program are most likely to improve outcomes associated with program participation based on current knowledge about evidence-based, research-based, and promising programs. WSIPP will consult with the Reentry Services Work Group (administered by the Health Care Association) in 2022 to determine any additional research parameters for the final report.

The preliminary report can be found here. A final report was originally due November 1, 2023. In September 2023, the WSIPP Board of Directors voted to shift the deadlines to June 30, 2024.
