About Prop 1 and the Behavioral Health Services Act (BHSA)
California voters passed Proposition 1 to modernize and strengthen the state’s behavioral health system. As a result, the Behavioral Health Services Act (BHSA) now allows funding to support individuals with substance use disorders, in addition to those with mental health conditions.
BHSA aims to improve California’s behavioral health system by:
- Expanding access to care
- Restructuring how funding is used
- Increasing services and supports
- Prioritizing individuals and communities with the greatest needs
The BHSA builds upon the Mental Health Services Act (MHSA), first passed by voters in 2004. The MHSA—funded by a 1% tax on personal incomes over $1 million—has helped counties across California enhance local mental health programs and supports.
