Drug and Alcohol Abuse (CA only) (Archives, 2001-2017)

This database contains information on admissions for drug and alcohol treatment and the characteristics of persons admitted for treatment for drug and alcohol abuse. See treatment defintions for more information on treatment types and individual classification categories.  The area "Small County Composite" includes counties with less than 20,000 population: Alpine, Inyo, Mariposa, Modoc, Mono, Sierra, and Trinity.  Years refer to state Fiscal Years (FY), e.g., 2017 reflects the 2016-2017 FY. 

The source for 2001-2005 data is the California Drug Data System (CADDS).  The source for 2006 through current data is the California Outcomes Measurement System (CalOMS), also known as CalOMS Treatment or CalOMS Tx).  CalOMS is California's data collection and reporting system for substance use disorder (SUD) treatment services. 2001-2005 data are reported by calendar year and 2006 through current are reported by state fiscal year (July-June). Beginning 2006, variables not marked by an asterisk under "primary/secondary alcohol/drug problem" are included in the "other" category.

According to  California Department of Alcohol and Drug Data Programs, the lower values for Detox and NTP Treatment Types for 2006-2010 are most likely due to the increase in the number of Substance Abuse and Crime Prevention Act (SACPA) clients. The proportion of SACPA/criminal justice clients has gradually increased from about 20% of the total treatment population in 2000 to about 50% in 2007. SACPA clients may get treatment over non-SACPA clients and have very different characteristics. For example, as they often enter treatment from a controlled environment, such as jail, they don't require detox services. Also, many judges who refer clients to treatment prefer not to refer clients to narcotic replacement therapy.  See Substance Abuse and Crime Prevention Act of 2000 (Prop. 36) for more information.
