New Frontier Data conducted an analysis of data provided by 20 California counties to determine the number of people in California jails for marijuana-related offenses. They found that:
- Thousands of adults are incarcerated for marijuana offenses in California and the severity of sentences varies dramatically across the state.
- There is significant variation between counties in per capita rates of incarceration and length of sentences for similar offenses.
- Black people are significantly overrpresented in the population jailed for marijuana-related offenses.
