Welcome to the California Department of Alcohol and Drug Programs


CalOMS Treatment

The California outcomes measurement system-treatment (CalOMS Tx) is a statewide client-based data collection and outcomes measurement system. CalOMS will allow the Department of Alcohol and Drug Programs to effectively manage and improve the provision of alcohol and other drug services at the state, county, and provider levels.


Drug and alcohol treatment access report (DATAR) provides essential information about the capacity of California’s publicly funded AOD treatment system to meet the demand for services. In the past, DATAR information has supported requests for increased government funding.

Drug Courts - Evaluation Report

California’s first adult drug court began in Alameda County in 1991. In 1995, California’s first juvenile offender drug court began in Tulare County. The Department of Alcohol and Drug Programs (ADP) has supported the development of drug courts in California since 1998.

Indicator Sheets

The Office of Applied Research and Analysis (OARA), as part of its data analysis activities, compiles the report on California indicators of alcohol and drug abuse. The report reflects alcohol and drug information/data for a five-year period. The data may be used by county officials, researchers, students, or others to trend analyses, calculate rates, and to perform other manipulations based on each user’s need or interest.

Prop 36, UCLA, OCJC

The Substance Abuse and Crime Prevention Act OF 2000 (SACPA), also known as Proposition 36, passed by 61percent of California voters on November 7, 2000. This initiative allows first and second time non-violent, simple drug possession offenders the opportunity to receive substance abuse treatment instead of incarceration. The law became effective statewide on July 1, 2001. SACPA requires the state to fund a long-term evaluation and to submit an annual report on the effectiveness and financial impact of the programs funded pursuant to SACPA requirements.


The Substance Abuse Research Consortium (SARC) meetings offer an opportunity for professionals from a variety of disciplines (academic and agency research, law enforcement, criminal justice, treatment practice, and policy analysis) to exchange information on California substance use trends, promising prevention and treatment strategies, criminal justice/social service partnerships, and other substance abuse-related topics.

SIG Evaluation Reports (PDF)

The Center for Substance Abuse Prevention, part of SAMHSA, funds the State Incentive Grant (SIG) Program. The goal of SIG is to enhance the alcohol and drug prevention system throughout the state, through collaborative planning efforts at state, county, and local program levels through the development and implementation of science-based prevention programs and services.
