Mental health and substance abuse social workers in California assess, treat, and support people living with psychiatric disorders and addiction. To enter the field, you typically need at least a bachelor’s degree in social work or a related field. For clinical practice and LCSW licensure — which allows you to diagnose and treat within scope of licensure and state regulations — you’ll need an MSW and approximately 3,000+ supervised hours.
One in six Californians lived with a mental illness as of 2019 data. One in 24 had a condition severe enough to impair their daily functioning, based on recent available data. Based on available state and county data, a third of adults who received county mental health services for serious mental illness also had a co-occurring substance use disorder. These numbers describe neighbors, family members, and people sleeping in doorways across the state.
As Charmaine Dorsey, MSW, LCSW, Director of Patient and Social Support Services for LA County Department of Health Services, put it: “The patient is whole: mental health, social health — all those affect each other.”
California has been building toward an integrated response to this crisis for decades. Mental health and substance abuse social workers are central to that effort — working inside county systems, hospitals, courts, housing programs, and community clinics to reach people that other systems routinely miss.
California by the Numbers

- One out of 24 California adults has a mental illness that impairs their daily functioning (based on recent available data).
- Eighteen percent of adults reported binge or heavy drinking in 2020.
- From 2016 to 2020, alcohol was involved in 28 percent of motor vehicle crash deaths.
- A third of adults who received county mental health services for serious mental illnesses had a co-occurring substance use disorder (based on available state and county data).
- People with drug or alcohol use disorders are almost six times more likely than the general population to attempt suicide.
- From 2018 to 2020, there were 17 drug overdose deaths per 100,000 people in the state.

California Mental Health and Substance Use Disorder Treatment
The CDC identifies the integration of behavioral health into primary care as an evidence-based strategy for improving mental health outcomes and reducing drug and alcohol use. That integrated model places social workers at the center. Primary care teams that include social work case managers and behavioral health consultants can catch problems earlier, reduce care gaps, and reach patients who fall through the cracks of a fragmented system.
Mental health disorders and substance use disorders frequently occur together, and simultaneous treatment is required for lasting recovery. Stigma and a widespread misunderstanding of these as moral failures rather than chronic diseases make that treatment harder to access — especially for vulnerable Californians who already face barriers to care.
The problem runs deep. When Governor Newsom was mayor of San Francisco, he observed that a third of the city’s 7,500 unhoused residents were suffering from untreated mental illness and that California’s jails had become, as described in policy discussions, “de facto asylums.” Based on available estimates, more than 30 percent of California prisoners were receiving treatment for a severe mental disorder.
California has responded with sustained legislative action. The 2020 Mental Health Services Act levied a 1 percent tax on millionaires to fund community-based, culturally responsive mental health programs. The 2018 No Place Like Home Act authorized $2 billion for affordable housing paired with on-site mental health and social services. Each of these measures relies on social workers to make them real in people’s lives.
There is strong demand for professionals in this field across a wide range of settings:
- County systems
- Courts and correctional facilities
- Drug rehabilitation centers (inpatient, outpatient, detox)
- Permanent supportive housing programs
- Community mental health service agencies
- Inpatient and outpatient psychiatric facilities
- Hospitals and emergency departments
- Crisis intervention organizations
- Schools
- Nonprofit community mental health organizations serving transition-aged youth and young adults
- Primary care clinics providing integrated primary and behavioral health care
- Research centers, including UCLA’s Center for Health Policy Research and the UC Davis Center for Healthcare Policy and Research
Harm reduction programs, HIV prevention initiatives, public defender support for clients with mental illness, and court diversion programs all require social work expertise. The career pathways in this specialization are broad.
Examples of Mental Health and Substance Use Disorder Programs in California
The California Health Care Foundation
This independent nonprofit works to improve California’s health care system with a particular focus on low-income Californians and communities that face the greatest barriers to care.
CalAIM (California Advancing and Innovating Medi-Cal)
Launched in early 2022, CalAIM transforms the Medi-Cal program by offering whole-person care and addressing fragmented services for people with behavioral health needs through Enhanced Care Management (ECM) and community supports.
California Improvement Network (CIN)
CIN works toward health equity by coordinating health and social services across communities, connecting health care organizations with community-based providers offering food, housing, legal, and other support.

California Laws Governing Mental Health and Addiction Treatment
Social workers practicing in mental health and substance abuse settings must understand the laws and regulations that govern these areas. California’s legal framework is among the most complex in the country, and it continues to evolve.
Licensing and Certification
California has stringent licensing and certification requirements for mental health and substance abuse practitioners. The California Board of Behavioral Sciences oversees LCSW license requirements in California and sets the standards that govern social work practice in clinical settings.
Confidentiality Laws
Protecting the privacy of people seeking mental health and substance abuse treatment is foundational to the work. Social workers must follow HIPAA and California-specific regulations, including the Confidentiality of Medical Information Act (CMIA). These laws aren’t bureaucratic formalities — they’re what make it possible for clients to trust the people trying to help them.
Involuntary Treatment
California’s involuntary treatment laws are actively changing. In October 2023, Governor Newsom signed Senate Bill 43, which expanded the definition of “gravely disabled” under the 1967 Lanterman-Petris-Short Act to include people with a severe substance use disorder or a co-occurring mental health and substance use disorder.
Newsom’s Community Assistance, Recovery, and Empowerment (CARE) Court — signed into law in September 2022 and first implemented in San Francisco, San Diego, Orange, Riverside, Stanislaus, Tuolumne, and Glenn counties — allows for court-ordered treatment plans for people with untreated schizophrenia spectrum or other psychotic disorders. Both CARE Courts and the reformed Lanterman-Petris-Short Act face civil rights criticism. Social workers practicing in these settings must track these developments carefully to remain in compliance and to advocate effectively for their clients.
Discrimination Protections
State laws protecting Californians from discrimination based on physical and mental disabilities include the California Fair Employment and Housing Act (FEHA), the Unruh Civil Rights Act, and the Disabled Persons Act. Social workers in this specialization need working knowledge of all three.
What Do Social Workers Do for People with Mental Health Disorders and Substance Use Disorders?
Dr. Jagruti Shukla, the Los Angeles County director for primary care, describes the problem directly. “We know the patient has diabetes; we are trained to treat them,” she told CalMatters. “But when they are street homeless, they have alcohol addiction, they haven’t eaten in two days…the conversation never moves to health.”
Social workers move that conversation. They address the psychosocial dimensions of addiction, help clients build coping skills, and navigate the social barriers that prevent people from getting care. Through assessment, observation, and collaboration with other health professionals, they apply evidence-based practice models — see also the role of MSWs in mental health advocacy — and connect clients with the community resources they actually need.
In California’s most underfunded and underserved communities, mental health social workers often serve as a consistent point of contact for people the health care system has struggled to reach. How will you serve?
